Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. [1] The main concerns in groundwater engineering include groundwater contamination , conservation of supplies, and water quality .
The Journal which was issued once a year became a monthly. Apart from maintaining high standards for the Journal, a series of other publications, Memoirs, Lecture Notes, Field Guide Books, Mineral Resource Series and Text Books of Geology and Mineral Resources of individual States have been brought out.
Agricultural hydrology is the study of water balance components intervening in agricultural water management, especially in irrigation and drainage. [ 1 ] Illustration of some water balance components
The energy balance of groundwater flow can be applied to flow of groundwater to subsurface drains. [2] The computer program EnDrain [3] compares the outcome of the traditional drain spacing equation, based on Darcy's law together with the continuity equation (i.e. conservation of mass), with the solution obtained by the energy balance and it can be seen that drain spacings are wider in the ...
Groundwater and surface water flows can be studied with hydrologic simulation. A typical program used for this work is MODFLOW. However, simulation models cannot easily help make management decisions, as simulation is descriptive. Simulation shows what would happen given a certain set of conditions.
In hydrogeology, groundwater flow is defined as the "part of streamflow that has infiltrated the ground, entered the phreatic zone, and has been (or is at a particular time) discharged into a stream channel or springs; and seepage water." [1] It is governed by the groundwater flow equation. Groundwater is water that is found underground in ...
Graphic on Groundwater Flow. Groundwater-Dependent Ecosystems (or GDEs) are ecosystems that rely upon groundwater for their continued existence. Groundwater is water that has seeped down beneath Earth's surface and has come to reside within the pore spaces in soil and fractures in rock, this process can create water tables and aquifers, which are large storehouses for groundwater.
Although one well may be sufficient to solve groundwater and soil salinity problems in a few hectares, one usually needs a number of wells, because the problems may be widely spread. The wells may be arranged in a triangular, square or rectangular pattern. The design of the well field concerns depth, capacity, discharge, and spacing of the ...
