  The Soil erosion mapping is the priority basement of soil conservation program in the watershed management. This study aimed to apply the FAO model and assessing factors affecting erodibility of soil using GIS and producing soil erosion map in Maroon watershed. For this purpose, the basin maps were digitized in a scale of 1:50,000 and they were integrated with each other by using ArcGIS10.3 software. Homogeneous units map was produced. Then, according to the scoring table used in the model of FAO and surveying using GPS in the field and apply the factor scores for each homogeneous units was estimated the final score for each factor and the severity of erosion in homogenous units by GIS. Finally, the produced weight map was reclassified according to the FAO model and the minimum and maximum score of the erosion for the evaluated factors. It was categorized in four classes by including low, medium, high and very high classes. The results revealed that 95 percent of the study area located in the moderate erosion (49.06%) to high (45.98%) and only 5% of the area in the relatively moderate erosion (3.66%) and very high (1.30%) were occurred.

  Soil erosion is one of the environmental problems which can be considered as a threat for natural resources, agriculture and the environment. Thus, determining the temporal and spatial extent of soil erosion is an effective way to management of soil erosion and sediment control through watershed management. Todays, the misuse of lands and converting forests and grasslands into agricultural land, overgrazing, tillage on steep slopes leads to increase soil erosion and sediment yield. Therefore, defining the contribution of different land uses has a significant role in preventing erosion and prioritization of land management activities The objective of this study is to estimate and compare the rate of soil erosion in in different land uses on the current status and prediction of erosion in Two main scenarios and each mail scenario has three sub-scenarios (25, 50 and 75 percent of area) at KalaybarChay watershed with an area of 452 km2 in the province of East Azerbaijan using USLE model. To predict the foregoing, land use map was prepared Using Universal Soil Loss Equation (USLE), Geographic Information Systems (GIS) and TM Sensor of satellite image Landsat5 on the ENVI 4.3 software. After the preparation of USLE model factors includes R, K, LS, C and P model was performed and mean value of each factor was calculated and soil erosion map was prepared by multiplying the average values. Results showed that the average amount of soil erosion rate is 12.3 (ton/ha/yr). Also the highest and least rate of erosion is assigned on conversion of rangeland to dry farming scenario; and the rangeland to tree dryland scenario equal to 15.43 and 9.03 (ton/ha/yr), respectively.

  Nowadays, knowing the amount of soil erosion is an important part of the comprehensive management ofwatersheds. Due to the lack of sufficient information and data relating to water and sediment discharges inwatersheds, soil erosion is estimated using user-friendly models and new technologies. The aim of this study isto predict erosion and sediment yield in the Darkesh watershed, North Khorasan province, usingWaTEM/SEDEM model and RS and GIS and image fusion algorithm. At the first, the crop management factor(C) was mapped based on land use map. The Gram-Schmidt algorithm was used to combining multispectralimages Landsat 7 and 8 with panchromatic images for the two satellite images with 12-year time distance (2003and 2015) and a scale of 1:25,000. The maps of other input factors were then prepared using ArcGIS and ENVIsoftware and the model was run and the rates of erosion and sediment yield with the scale of 1:25,000 waspredicted with and without image fusion algorithm and were compared with the observed rates in the watershed.Comparing observed sediment data in Darkesh watershed with predicted amounts showed that the final map oferosion classification by applying image fusion algorithm led to better and more accurate identification oferosion sensitive areas. Based on the results of this study, high-performance of WaTEM/SEDEM model topredict of sediment yield was proved and it was found that image fusion algorithm was also led to increase theaccuracy of the results.

  Soil erosion management requires providing appropriate solutions that can be achieved with knowing soil erosion situation. The aim of this study, modeling rill erosion potentially by using maximum entropy (MaxEnt) and investigation of its robustness to knowing about rill erosion susceptibility in the Golgol watershed, Ilam province. To this purpose, different geo-environmental factors were selected to be employed in the modeling process. In addition, 157 rill erosion events were recorded by a global positioning system (GPS). These events were then classified into two classes of training and validation with a ratio of 70:30. To evaluate model robustness, these classifications were repeated three times, and therefore, three sample datasets (D1, D2, and D3), were prepared. The area under receiver operating characteristics (AUC) curve was used for evaluating the performance of the model. Regarding the robustness results, all of the datasets obtained good AUC values and all of them were robust for both the goodness-of-fit (RAUC =1.3) and prediction performance (RAUC =3.1). In other words, the results demonstrated that the model remained quite stable when the calibration and validation data were changed. In addition, we found that the MaxEnt model is capable to produce rill erosion susceptibility map. Furthermore, based on the sensitivity analysis, it found that the most important components in rill erosion susceptibility modeling are lithology and distance from stream. The adopted methodology can be useful as an efficient approach for land use planning and erosion risk management. Manuscript profile

  Many factors affect soil erosion and runoff generation. However, the role of some factors such as freeze-thaw (FT) processes has not been well considered yet. The present study therefore aimed to simulate and explain the effect of FT cycle on runoff generation and sediment yield under rainfall simulation condition. Towards this attempt, air and different soil depth temperatures were analyzed in natural condition and 10 cm soil depth was targeted for the soil laboratory experiments. A FT cycle with three and two days for freezing and thawing was taken place. The rainfall storm with 1.2 mm/min and 30 min duration was simulated and conducted for three treatments in soil erosion and rainfall simulation laboratory of Tarbiat Modares University. The results showed that the induced FT cycle soil had a distinct and significant behavior and different from that seen for the control plot. So that, the times of runoff generation in freezed and FT cycle treatments were 2.74 and 3.25 times less, respectively, compared to that reported for the control plots. The runoff volume and sediment yield were also respectively reported in turn of 1.46 and 1.16 and, 11.92 and 2.65 times more for freezed and FT cycle induced treatments compared to those recorded for control plots. Ice lenses and frost heaves plus creating situations close to soil saturation after FT cycle were the most effective factors in distinct behavior of soil induced by Freezingand FT cycle.

  Soil erosion is one of the most challenging issues in optimal conservation of soil and water resources. Land surface cover affects runoff production and soil loss processes. Nowadays, miscellaneous amendments and conditioners are being applied to conserve water and soil worldwide. However, the role of environmentally friend and available organic amendments have been rarely considered. This study was therefore taken place in order to assess the effect of rice straw (0.5 kg m-2) on runoff volume and soil loss on a sandy clay loam placed in three small plots (0.5×0.5×0.3m) with 20% slope steepness using rainfall simulator. The study plots were then subjected to 50 and 90 mm h-1 rainfall intensities for 15 minutes after spreading rice straw on the soil surface. The results showed that the rice straw treatment under 50 and 90 mm h-1 rainfall intensities and in comparison with control plot reducing the runoff about 90% and 96%, respectively. In addition, soil loss was completely controlled in treated plots and under both studied rainfall intensities. All differences were found statistically significant at 1% significancy level.  Manuscript profile

  Simulation of runoff resulted from any significant rainfall events can help to estimate the severity of floods. To protect watersheds, application of a model which is able to predict runoff at certain times and places is essential. Therefore, this study aimed to simulate runoff generation in upstream catchments of the Shahrake Behzisti as well as assessing the effect of implementation of vegetation management scenarios, using three relatively intense rainfall events occurred in recent years. The model of physically based Limburg soil erosion model (LISEM) within PCRaster GIS and programming language was applied in this study. In order to run the LISEM model, four basic raster maps of digital elevation model, landuse, soil texture and roads (impervious areas) were prepared. Digital elevation model map of the catchment was extracted from the Ultracam image of 1 m resolution within the ArcGIS environment. During this study, only two events on 2/11/2014 and 16/9/2015  led to runoff generation. Thus, the first event was used for calibration and the second one for validation of the model. Statistical comparison of the simulated and observed hydrographs of the rain events on 2/11/2014 and 16/9/2015 showed the correlation coefficients of 0.80 and 0.76 and Nash-Sutcliffe criteria of 0.8 and 0.5 respectively. The results of the simulation showed that the model was able to predict total runoff, peak discharge, runoff initiation time and time to peak discharge with relatively good performance. The results of the application of the LISEM model showed that runoff volume and peak discharge significantly decreased by implementation of vegetation management scenarios. Manuscript profile

  In recent years، conservation agriculture has emerged as a multidimensional approach to the sustainable use of water and soil resources and the achievement of sustainable development goals. Despite the efforts، development process of this approach is slow and faces many obstacles. In the present study، an attempt was made to examine the obstacles to the development of conservation agriculture from the mental dimension of the experts of the Research Center. The target population was the experts of Sararud Research Center in Kermanshah in 2019-2020 who were studied purposefully. In this regard, Q methodology was used. This method is one of the mixed research methods. Based on the findings of the Q-factor results، the number and manner of groupings show that the range of mindsets and opinions of experts regarding barriers to conservation agriculture have differences and similarities. Therefore، according to the purpose of studying Q and the criterion of interpretability of factors or groups, 5 categories (technology-centric، tradition-oriented، knowledge-centered, cognitive-centric, institution-centered) of the mentality and beliefs of experts in Sararud Research Center Kermanshah has been obtained. Each group had different mindsets and attitudes about barriers to the development of conservation agriculture. Given the prevailing mental model identified (central institution)، it is recommended that the government provide incentives and grants (loans، etc) to beneficiaries so that they can apply the method conservation agricultural farms.

  the lithological maps is inevitable in the preparation of rock unit’s erosion susceptibility maps. In this study, rock unit outcrops in the Soh Basin (50 km Northern Isfahan) were extracted using nonlinear correlation analysis of satellite data. Moreover, rock unit’s erosion susceptibility such as marl, shale, and quaternary deposits and resistant rock units such as sandstone and limestone were extracted based on soil erosion intensity factors. The lithology of the basin was studied usingthe virtual variables method. Initially, rock units, as a virtual independent variable, and the PC1 (the first principal component) of ETM+ multispectral bands were by amultiple linear regression model. Afterward, rock units were in logistic regression analysis as virtual dependent variables. The results revealed that logistic regression analysis is a suitable model for rock unit’s extraction.           Manuscript profile

  Soil erosion is always occurred as a natural event but human false interference led to accelerated soil erosion and irreversible effects. Mahabad dam watershed, due to topographic mountainous and steep slopes is very susceptibility against soil erosion. The aim of this study is to prioritize the factors affecting sediment production using fuzzy logic and AHP models and finally, generating the susceptibility mapping apron to soil erosion in Mahahbad dam watershed.  At first, based on expert experiences seven factors were recognized on soil erosion including the following; slope degree, land use, time of concentration, elevation of sea, precipitation, lithology and distance to river. The susceptibility soil erosion map based on fuzzy logic and AHP models were classified in five classes. The accuracy of the erosion susceptibility map provided by the model is further checked by calculating Seed Cell Area Index (SCAI). Results show that about 102.12 km2, equivalent to 13.15% of the area has the potential to "very high" risk of erosion and sediment production, which in the sub-basins Dehbokr, Bangvyn, Qzljeh, Maraneh and Syahghol has more potential.

  Abstract Identification,  evaluation  and  prioritization  of  different  areas  can  produce  valuable information for the watershed comprehensive plans, soil conservation and mitigation of the erosion types based on amount of erosion and sedimentation. This study used the MPSIAC and EPM models as a comparison and prioritization to estimate erosion and sediment   in   the   Aro   Watershed   Basin.   Required   data   regarding   the   natural characteristics  of  studying  the  watershed  basin  was  provided  from  comprehensive studies  of Hableh-Rood  basin  and  field  studies.  By using the required  factors,  the amount of erosion was calculated in both the models. In the MPSIAC model, erosion was calculated to be 451 m3/km2/y, whereas sediment was calculated as 233 m3/km2/y. However, the rate of erosion in the EPM model was estimated to be 378 m3/km2/y and for sediment, it was 200 m3/km2/y. The results showed that in some subbasins there was good correlation between the MPSIAC and EPM models, however in areas with high erosion the EPM model has less certainty than the MPSIAC model. The highest area was moderate class in the both of models and both of erosion and sediment in terms of spatial distribution. The results showed that EPM and MPSIAC model have not good agreement in the all classes. Prioritization of the hydrologic units showed that A4 unit in the EPM model and A-1-4-3 unit in the MPSIAC model allocated maximum of amount of erosion and deposition, in this area.

  The knowledge of erosion estimating is requisite for controlling soil erosion. The purpose of this research was estimating annual soil erosion using anatomical changes in exposed roots of Carpinus Orientalis in Hassan abad valley, Chaloos, Iran. For this purpose, we select eight Carpinus Orientalis trees as quite random and cut their exposed roots. Moreover the geographic coordinates of trees, the slope intensity and direction, altitude and percentage of vegetation has been written. Cross-sections of 20 µm were prepared using microtome and the first year of exposure by erosion was identified. We finally estimated the mean annual erosion.  The statistical relationship of the mean annual erosion with the percentage of the plant coverage, geographical aspects and slopes were investigated. The mean erosion of the study area has been estimated around 0.4 mm per year. There was positive relationship between annual erosion and slope density and negative relationship between the annual erosion and percentage of the plant coverage. The samples obtained in southern aspect showed higher annual erosions. We concluded that anatomical changes of exposed roots (Dendrogeomorphology) of Carpinus Orientalisare valuable tools to date erosion events, however, the responses of diverse species under different types of erosion remains to be studied in future.

  Soil Management (SM) is critical to human well-being that it is more important now because of meeting the high demands for food production and satisfying the needs of an increasing world population. Therefore, the purpose of this descriptivecorrelation study was to investigate the effective factors on wheat farmers’ adoption of Farming Methods of Soil Management (FMSM). The research instrument was a structural questionnaire with close-ended questions, which its validity and reliability was confirmed. The target population included all wheat farmers in West Azerbaijan Province (N=24949) that among of them, 371 wheat farmers was chosen by using Krejcie & Morgan’s table through multi-stage sampling (n=371). The descriptive results showed the majority of farmers (237 or 63.90%) had moderate adoption of FMSM. These results also indicated farmers used three FMSM namely 1) using crop rotation, 2) using animal fertilizers, and 3) using soil testing more than others did. On the other hands, there were significant relationships between some of personal, farming, social, economic, and extension-education characteristics of farmers and the amount of their adoption of FMSM. Finally, stepwise regression analysis revealed that 35.30% (R2=0.353) of the variances in the amount of farmers' adoption of FMSM could be explained by the five variables namely farm size, knowledge about FMSM, the amount of extension contacts about FMSM, distance between farm and agricultural service centers, and the amount of attitude toward FMSM.

  هدف از این مطالعه، بررسی تاثیر جاده سازی در میزان ذخیره کربن در حوزه آبخیز زیارت می­باشد. بر این اساس از 5 کاربری جنگل، مرتع، کشاورزی، جاده و آبراهه نمونه برداری و میزان کربن آلی هر کدام محاسبه شد. نتایج نشان می­دهد جاده سازی عامل کاهش ذخیره کربن آلی بوده و میزان آن تفاوت زیادی در کاربری جنکل و سایر کاربری­ها دارد. میزان ذخیره کربن آلی در   کابری­های جنگل، مرتع، کشاورزی، آبراهه و جاده به ترتیب 143، 136، 128، 36 و 29 مگاگرم در هکتار می­باشد. نتایج این مطالعه می­تواند در ترسیب کربن و کاهش گازهای گلخانه‌ای مفید باشد.
