GroMoPo Metadata for Poondi Micro-Watershed model

Ground water is one of the major source of water for drinking and agriculture in rural areas. Due to rapid increase in population, urbanization and industrialization, the consumption of ground water has been increased which leads to the over exploitation of available groundwater sources. The present study focuses on simulating the discharge groundwater pattern for Poondi micro-watershed, Tamil Nadu, India using Visual MODFLOW. United States Geological survey developed a finite difference discharge model named Visual MODFLOW. The ground water flow equations are represented in terms of computer codes. The steady and transit state conditions were calibrated using the Visual Modular Three-Dimensional Finite-Difference Groundwater Flow Model (Visual MODFLOW). The calibration and validation was done for the period 2012-2018. The optimization of the model for spatial distribution of hydraulic conductivity and storage properties was done using trial and error technique. The model output show that ground water level mainly depends on precipitation and recharge rate. Due to the presence of river and the water level contours, prediction using the model showed high ground water level in Poondi.
