Ground water moves from levels of higher energy to levels of lower energy, its energy being essentially the result of elevation and pressure, the velocity heads being neglected since the flow is essentially laminar. The velocity is very small in the laminar range—of the order of 1 cm/sec—and the Reynolds number (Re) for ground water […]

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 […]
