  Background and Objective: Drought is a natural and repeatable disasterwhich affects all climates. Because of the intrinsically dry climate and low precipitation in Sistan plain, the main water resources are surface water originated from a neighboring country. This study investigates the relationship between meteorological and hydrological drought in Sistan plain. Method: At first, meteorological and hydrological drought were investigated by indices including moving average, SPI and SDI in Sistan plain. Moreover, the relationship between them was evaluated for 45 years. Findings: Results show that indices of meteorological and hydrological droughts do not match with each other in the entire of the study period, but there is a significant relationship between them during dry years. It was also observed that a drought period started in 1999 and continued until 2012. Discussion and Conclusion: Therefore, due to low volume and high coefficient of variations of rainfall and vital role of surface flows in the supply of water in the plain, hydrological drought shows conditions of drought is better than the meteorological drought in Sistan plain.   Manuscript profile

  In optimal planning and management of natural resources, knowledge of how land cover changes and land use and the factors that cause it are very necessary. In this field, remote sensing data have high potential to study temporal and spatial changes in land cover and land use. The purpose of presence study is prediction and assessment of the trend of land use changes and land cover in Zahak area of Sistan plain. For this purpose, land use and cover maps were prepared from landsat satellite images using support vector machine method of supervised classification in 1987, 2001 and 2018. Then, using the land use map in 1987 and 2001, land cover in 2018 was predicted. Land use maps for 2001 and 2018 and land cover for 2030 was predicted using integrated method of Markov chain and automated cells. To analyze the trend of land use changes and land cover since 1987- 2001, 2001- 2018 and 2018- 2030, Land change modeler was used. Results indicated that areas of watery agriculture 2013 hectares, tree cover 1117 hectares, water areas 2391 hectares and barren lands 9535 hectares has decreased since 1987- 2001. Also, the mulching area uses area 192 hectares, and sand dunes 14864 hectares were increased. During the period 2001- 2018, the areas of watery agriculture land uses 3533 hectares and barren lands 3707 hectares has decreased and uses area tree cover 313 hectares, water areas 5385, mulching area 247 hectares, and sand dunes 1295 hectares were increased. In the forecasting the time period 2018- 2030, the area of uses watery agriculture will be 1098 hectares, sand dunes 527 hectares, and barren lands 2020 hectares are reduced. In this forecast, land use of tree cover 16 hectares, water area 3607 hectares, and mulching area 23 hectares will increase. Manuscript profile

  Sand dunes are one of the most important facies of wind erosion. Our understanding of the complex interactions of sand dunes is often limited by the lack of accurate morphological data. The erosion and sedimentation process is very important and there is currently a lack of field data for executive projects, study plans and validation of erosion and sedimentation models. Images of the study area were taken using a Phantom 4 Pro UAV at an altitude of 60 meters on September 22, 2019. This type of UAV, which is small and light, with its 20-megapixel camera and GPS, can provide high quality images. After separating the dunes, a three-dimensional area in terms of square meters and volume in terms of cubic meters were obtained. And the product of a small amount of bulk density of soil in terms of cubic centimeters and the volume of dunes in terms of cubic meters The weight of the dunes was obtained in terms of tons.In the study, the slope percentage and sediment height were determined based on the windward part and the wind shelter of the dune The highest wind area was slope 10-20% And the maximum sediment is in the slope of 70-100% And in the wind shelter, the maximum area was on a slope of 30-50% And the highest sediment was determined in the slope of 70-100% .

   In order to be aware of groundwater-level fluctuations in arid and semi-arid regions, it is necessary to make an accurate forecast of the groundwater depth situation. The drying of Hamoon lake, severe water shortages and significant reduction in groundwater levels have led to critical environmental conditions in the Sistan plain. Spatial understanding of groundwater depth changes in the region and awareness of the severity of groundwater depletion are important for the development of water resources management strategies. Therefore, this study was conducted with the aim of zoning groundwater depth using geostatistics and GIS techniques in the agricultural lands of Sistan plain located in the east of Hamoon Lake, with an area of about 201000 ha. For this purpose, groundwater depth data were collected from 846 wells by field survey using piezometric wells in the study area.  In this research, various geostatistical methods including deterministic interpolation method and geostatistical methods were evaluated to compare the prediction ability of groundwater depth spatial variations. The results showed that the intensity of groundwater depth changes in the study area with a coefficient of variation of 19.87% is moderate. The spherical model could better explain the spatial variation of the experimental variogram of the studied parameter in the region. Finally, the results related to the deterministic method of inverse distance weighted with power 2 estimates a better prediction for groundwater depth zoning than kriging and cokriging geostatistical methods.

  The main goal of this study is to investigate theinteractionbetween East Khorasan winds regimesand Sistan120 Days winds. The climatic data  of Synoptic stations used in the present study was obtained fromkhorasan razavi, khorasan jonobi and sistan and baluchestan meteorological organizations. The statistical period is from 2000 to 2011.  To do synoptic analyses, the maps of sea level pressure, geopotential height of 850 Hectopascal level, wind direction and the relativevorticity were used. The sample  extract form  the daily wind velocity data base of Zabol station and include the fourteen days with the highest velocitywinds.  The results shows that the wind direction in the Khorasan Razavi province is from north. while, the direction changes toward Northwest as it arrives to Sistan plain. This change in the direction of wind is due tothe topographyand geographical location of thearea. The geopotential height maps shown that the main reasons for the winds of 120 days are thecore ofthe highpressureonthe Caspian Sea and the core of the low pressure in Pakistan. Moreover, strengthening the low pressure intensifies the winds Manuscript profile
