For the development of groundwater resources in a given area, knowledge of the occurrence and movement of groundwater is required. In addition, the hydrological parameters of the aquifers are needed to decide the location and types of wells. The geological conditions of the area will influence the occurrence and movement of groundwater. Hydrogeology refers to the study of the laws [...]
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 graphical method of superposition that [...]
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 flow varies from 1 to [...]
