Assessment, development and management of ground water from confined aquifers of a hilly terrain

Abstract

The object of the project is to study Characteristics of aquifer in the vicinity of National Institute of Technology, Rourkela Campus in assessing the ground water resources and the extent of utilization. The purpose of exploration was to establish aquifer constants such as transmissibility (T), storage coefficient(S), permeability (K) and yield through pumping tests. Several pumping tests, including those conducted this for project work, were carried out in non- equilibrium or unsteady state condition. The results were analyzed based on the following methods:
(a) Theis method of solution
(b) Jacob Method of solution
(c) Chow Method of solution
(d) Recovery Test
The results were interpreted and studied to get an idea of ground water potential and the yield. The results gave us an indication of satisfactory yield from the well (chosen for our project). The results of all the above tests are indicated in this project report. The results obtained from the above tests confirmed that the confined aquifer existing in the said area can provide satisfactory amount of water for use at least for gardening purpose. For the use of this water for additional supply for the drinking purpose needs further tests for quality. This location being in the vicinity of an industrial area it is suspected that the ground water is likely to contain more iron contents than the prescribed limits. Therefore, it is suggested that the water from this well should be used for drinking purpose after confirming the quality through Physical Tests, Chemical Tests and Pathogenic tests etc.
