Abstract |
|
Drought is the disastrous natural phenomena. It differs from other natural hazards by its slow accumulating process and its indefinite commencement and termination. To analyze drought its intensity is necessary. Meteorological drought is related with the lack of precipitation. Hydrological drought is related with effects of precipitation (including snowfall) shortfalls on surface and subsurface water supply, stream flow reservoir, lake levels, and ground water level. Vegetation drought is concerned with the decrease in crop production due to lack of precipitation or lake of water supply to the crop. In this study, drought intensity is determined by Standardized Precipitation Index (SPI) for meteorological drought, Standardized Water Level Index (SWI) for hydrological drought for the Patan district. The correlation change of rainfall with the ground water level is also explained. |
