The non-equilibrium equation can be used to determine the storage coefficient and transmissivity of confined aquifers. These aquifer constants are useful in the design of tubewells and for studying groundwater movement. Several approximate solutions have been developed for the purpose. Some of them are outlined in the following paragraphs: 1. Theis Method: This is a […]

How to Construct Multiple Well Systems? | Geography
Article shared by : 
In this article we will discuss about how to construct multiple well systems. If there are a number of pumping wells in a given well field, the drawdown at any point is the sum of the drawdowns due to each pumping well, for which the distance of the point from each well and the discharge […]
How to Measure Well Losses? | Geography

The ultimate drawdown in a well measured at the designed rate Q of continuous pumping for a given period is different from the theoretical drawdown due to well losses. The total drawdown sw is made up of: (i) Head loss resulting from laminar flow in the formation (formation loss), (ii) Head loss resulting from the […]
