A Statistical Hydrometeorological Analysis of North Gujarat Region

Meteorology is the key driving force of hydrology along time, from the immediate states and processes until the monthly, yearly, seasonal and sometimes multiyear sequences. Meteorology influences much of the hydrological flows and storages. The Mehsana district area has been facing severe water scarcity due to scanty precipitation and intensive agriculture during the last few years. The present study shows that the average rainfall in the Mehsana district is around 743 mm and the average depth to water level in this region is very deep particularly during pre-monsoon, where the water level lies below 25m at almost all the places. Groundwater level varies from 20.16 mm to 174.70 mm in the Mehsana region which shows very high difference in underground water level at various places in the study area. Hydrometeorology study indicates that uncontrolled extraction of groundwater is the only cause leads to unpredictable relation between precipitation and ground water level.
