Determining corrosion and sedimentation potentials is one of the most significant quality aspects of groundwater in different expenses. So, the aim of this study is to appoint corrosion and sedimentation potentials by applying Langelier and Ryznar indexes and their compilers in Marvdasht-Kharameh plain underground water. For this purpose, 49 wells of agriculture well were sampled in five years and compilers of total hardness (TH), total dissolved solubility (TDS), total alkalinity (TA) were measured. Simple kiringing statistical earth method was used for mapping of Rynzar and Langelier indexes and their compilers. The results demonstrated that spherical model is the best fitting for Langelier and Ryznar indexes and their compilers. The effect scope for variable compilers was from 15752 to 32711.local correlation class modified from good to intermediate quality. The average of Langelier index was 0.58 that displayed low sedimentation potential to intermediate. The average of Ryznar index was 6.3 which exhibited low corrosion potential in Marvdasht-Kharameh plain aquifer. Based on mapping plots, in the northern parts, TH and TDS compilers and consequently the Langelier index had the most quantity that it displayed intermediate sedimentation potential. Probably in the northern part, carbonate compositor’s effect was evaluated as an increasing factor .By regarding to sedimentation and corrosion potentials, Marvdasht-Kharameh underground water has entirely intermediate quality.

Due to the growing demand for water and water use variation, simulation of water reservoirs operational parameters is the most practical and important works to achieve the optimum management of dams. In this study, the operation of the Soork Dam’s reservoir was simulated using HEC-ResSim. The simulation was performed based on the input flow data during 2001-02 years to 2010-11, downstream water needs and physical properties of the reservoir. Preliminary results showed that the reservoir is not able to meet the downstream demands (Agricultural and environmental) in the most times. Three scenarios were defined and evaluated for dam performance in different situations. In this scenarios supply completely environmental demand and supply Percent of agricultural demand was evaluated by taking the right way irrigation. The results of the considered scenarios indicated that the downstream demands may meet in some cases. By changing planting pattern and increasing the efficiency irrigation can be best efficiency of water available in this area Manuscript profile

Evapotranspiration is the main source of water loss in basin and so knowledge of various aspects of water resources management is essential. Type text or a website address or translate a document. On the other hand, knowledge of the actual evapotranspiration plains is important to determine and manage crop pattern and irrigation of horticultural and agricultural. Due to the effects of climate change on all environmental aspects of watersheds, Check these changes on actual evapotranspiration of catchment is essential as a key factor in determining the water balance and water management planning for the sustainable management of natural resources and the environment. The aim of the present study is investigation of climate change effective on actual evapotranspiration in Tuyserkan Basin in west of Iran. For this aim MODIS satellite images and SEBAL algorithms was used to estimating of actual evapotranspiration in Tuyserkan basin for 10 years old. Impact of climate change was analyses through 15 atmospheric general circulation model and under two scenarios A1B and B1 in Software LARS-WG. The results showed that the probability of 80% in future periods, minimum temperature from 13 to 20% and maximum temperature from 2.4 to 6.4 percent has increase. Actual evapotranspiration is the probability of 80% in future periods will increase from 0.4 to 1.4%. Manuscript profile

Due to the importance of water and its vital role in human life, river studies and consequently studies on watersheds seem necessary. Golestan province with an area of 20437 square kilometers is located between latitude 36˚ 24΄ to 38˚ 0΄ north and 53˚ 51΄ to 56˚ 14΄ east. Gorganrood is one of the most important rivers in Golestan province and flows in the whole plain of Gorgan and divides it into two parts. Its catchment area is 10,250 km2. The main and important step in the study of erosion and sedimentation by experimental method is to determine and identify the forms and appearance of erosion. At this stage, various maps including river network, slope, geology, geomorphology, soil science and land use were studied; The map of the region was determined and the map was verified by interpreting aerial photographs and field visits. MPSIAC model was used to estimate the amount of erosion and sediment in the sub-basins. According to field studies and the results obtained, various types of erosions have occurred in the study area. According to the studies, the highest erosion was under the basin with code 1625220 (bed load 3.62 and with suspension 14.47) and the lowest erosion was under the basin with code 1624210 (bed load 0.32 and suspended load 1.3). Based on results, the sediment delivery ratio in the studied basins is between 23.6 to 39.6%. thus, the amount of special sediment varied between 1.6 to 18.1 and special erosion between 4.9 to 58.3 tons per hectare per year.

Runoff estimation is effective way in utilization and allocation of water resources for various agricultural, drinking, hydraulic and environmental sectors. In this paper, continuous simulation of rainfall-runoff in the basin with two different models including HEC-HMS conceptual model and data-processing model (artificial neural networks) are considered to evaluate the ability and accuracy of these two models in estimating runoff. The continuous flow simulation was used to calculate soil moisture losses (SMA) in sub-basins. For calibration of the model, daily precipitation, flow, evapotranspiration data from 2001 to 2007 were used and for model accuracy period of 2008 to 2011 were used. The results showed that the HEC-HMS model, along with the SMA model, has a good ability to continuously simulations in dry and continuous periods in the basin. In order to select the input variables that affect the flow rate in artificial neural networks, a generalized feeder grid (GFF) and a radial base function grid (RBF), partial interpolation algorithm (PMI) was used. The results of using the PMI algorithm showed that the input variable influences the flow velocity at the Gargar hydrometric station, the current day flow rate at this station. The results showed that the GFF network has more efficiency and accuracy than the conceptual model of HEC-HMS and RBF network in continuous run-run run simulation in the basin. The Nash coefficient for HEC-HMS and GFF and RBF networks is 0.6, 0.6677 and 0.6676 respectively Manuscript profile
