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 […]

The following tests may be performed to get an idea of the probable yield of the well: 1. Pumping Test: The water level is depressed to an amount equal to the safe working head for the subsoil. Then the water level is kept constant by making the pumping rate equal to the percolation into the […]
