Aquifer Modelling in Greater Noida Region (U.P) Using MODFLOW

Abstract

Groundwater is a very useful resource of water for domestic, industrial and agricultural necessities in Greater Noida. Groundwater withdrawal has increased in the last two to three decades due to the requirement of water in domestic, agricultural and industrial field. A part of Yamuna–Hindon River is incorporated for the study area. A careful study of water balance of a basin is essential for the effectiveness of groundwater management. The behaviour of the flow system and water balance was assessed by groundwater flow modelling. MODFLOW was established to quantify groundwater using steady-state finite difference model with 26 groundwater data from tube wells in Greater Noida region. Location map and well inventory are used to evaluate the groundwater level, direction and surface features. Different boundary conditions are used to recharge the ground by rainfall and irrigation returns, seepage losses from unlined canal and horizontal flows using diverse boundary packages available in Visual MODFLOW. In this study, hydraulic conductivity and recharge parameters are analysed by MODFLOW and are shown the sensitiveness of the model. For more optimistic urban groundwater intercessions to be executed in urban cities, we have to energize increasingly incorporated, foundational and quantitative assessment of the possible pathways, mediations and communications. This is progressively conceivable with the utilization of connected and coordinated demonstrating where groundwater procedure models, physical models and water industry models can be coupled and illuminate financial appraisal, where the estimation of water, in the entirety of its appearances, is progressively being perceived.
