Monitoring the Effects of Drought on Vegetation Cover and Groundwater Using MODIS Satellite Images and ANN
Author(s): Atta Areffian, Maryam Kianysadr, Saeid Eslamian, Ali Khoshfetrat, Saleh Yousefi
The main aim of present study was investigation on the effects of drought on vegetation cover and groundwater resources. In present study an available climatic data series (2001-2017) for 9 synoptic stations in Lorestan province were analyzed to detect wet and dry years by SPI. Also a long data series of MODIS data were analyzed by remote sensing data and the NDVI maps have been produced for study period (2001-2017). In addition the relationship between rainfall and groundwater level was investigated. Results of present study show that there is a direct significant correlation (R2=0.83) between SPI and the NDVI. In addition, results show that there is a significant correlation between groundwater level and three months ago precipitation at 95% confidence level. During study p... view more»
