Abstract

Today, in the wake of the global water crisis, all countries seek to identify, control, and utilize freshwater resources. Due to the fact that Iran is located in the desert belt of the earth and the reduction of precipitation has caused water scarcity in Iran and Kerman province, therefore identifying water resources and investigating changes in Snow Cover is necessary. Due to the harsh physical conditions of mountainous environments, it is not possible to permanently measure the terrain to estimate snow sources and to form a database. Therefore, using satellite imagery is very important for identifying snowy surveys and assessing its changes. In this study, we attempted to study the changes in Snow Cover reservoirs in Halilroud Watershed using MOD10A2 satellite imagery. For this purpose, Normalized Difference Snow Index was used. This index has a value greater than 0. 4, meaning a pixel with a NDSI greater than 0. 4 is referred to as snow and ice. The Snow Cover specified in the satellite images in ENVI5. 1 software was entered into GIS and was classified into 5 classes from 0 to 5000 and the survey of each class was calculated. Then they entered into SPSS and analyzed. Stepwise multivariate regression showed that during the 8-day interval of February (from 18 to 25 February), the most changes of snow survey had a significant and significant relationship with the snow survey trend in these years. In fact, the explanations for the snow changes in this time interval were related to height 3 (2001-3001) and then 4 (3001-4000), respectively. The 2001– 3001 height alone accounts for 98. 9% of the snowfall trend in the entire study area. Secondly, if the height of 4000-3001 is added, the two class, s justify 99. 2 percent of the snowfall change over the past 20 years.
