Assessment of Aquifer Parameters under Pravara Canal Precinct Using Pumping and Recovery Test Data
Journal Title: Universal Journal of Environmental Research and Technology - Year 2016, Vol 6, Issue 1
Abstract
Aquifer characteristics influence the movement of groundwater and contaminants along with it. Formations comprising of top overburden soil crest, gravel, and weathered rock leading to fissured rock, functioning as flow media are found in the study region. Seepage from agricultural lands and Pravara canal is the chief source of recharge to groundwater and movement of contaminants. The capacity to hold, transmit, water and dissolved solution is measured in terms of Transmissivity, Storativity, and permeability of the formation. Pumping& Recovery tests are carried out on four open shallow wells in the study region. In the absence of data on long duration pumping test with regulated discharge, recovery test data is used to arrive at the aquifer parameters; Transmissivity, Storativity, permeability, radius of influence using modified formula. The average value of Transmissivity, Permeability for well 1&2represent medium to good inflow with radius of influence of 114m&121.75m respectively, while that for well 3 indicate medium to low inflow with radius of influence of 60.52m.The average value for well 4 indicate low inflow with radius of influence of 63.92m.
