Recognition and Distinction of Hydrological Relations of Tashk and Bakhtegan Lakes Using GIS & RS Techniques

Abstract

Lakes as close ecosystems on the earth which have special patterns and hydrological relationships in lakes can determine the development or reduction trends of lake ranges, attachment or detachment between them, lakes water balance and also the changes and fluctuations in water regimes, during the time. Therefore, the Tashk and Bakhtegan lakes were studied, based on the regional climate studies and identification the droughness and wetness years, multi-spectral satellite images using the LANDSAT satellite (including the OLI, ETM+, ETM and MSS sensing images) and IRS during the years 1979_2013. Were used and analyzed and also the lake water level fluctuations during different periods were determined. Based on all used models from lakesin studied period, the hydrological relationship between lakes were proved, and the effects of climatic factors and in the stage after that, the effects of geomorphological factors as detachment factors for Bakhtegan and Tashklaked were determined.
