1Drainage equation — A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt s… …
2Drainage system (Agriculture) — An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production.=Classification=Figure 1 classifies the various types of drainage systems. It shows the field (or… …
3Drainage system (agriculture) — An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production. Contents 1 Classification 1.1 Surface drainage systems 1.2 Subsurface drainage systems …
4Groundwater recharge — Water balance Groundwater recharge or deep drainage or deep percolation is a hydrologic process where water moves downward from surface water to groundwater. This process usually occurs in the vadose zone below plant roots and is often expressed… …
5Depression-focused recharge — Also referred to as depression focused groundwater recharge. In hydrology recharge implies replenishing a supply of water held within a geological formation underground. Even surface aquifers are within soil. Contents 1 Recharge 2 Depression… …
6irrigation and drainage — ▪ agriculture Introduction artificial application of water to land and artificial removal of excess water from land, respectively. Some land requires irrigation or drainage before it is possible to use it for any agricultural production; other… …
7Aquifer — Typical aquifer cross section An aquifer is a wet underground layer of water bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be usefully extracted using a water well. The study of water flow… …
8Runoff model (reservoir) — A runoff model is a mathematical model describing the rainfall runoff relations of a rainfall catchment area or watershed. More precisely, it produces the surface runoff hydrograph as a response to a rainfall hydrograph as input. In other words,… …
9environmental works — ▪ civil engineering Introduction infrastructure that provides cities and towns with water supply, waste disposal, and pollution control services. They include extensive networks of reservoirs, pipelines, treatment systems, pumping stations …
10hydrologic sciences — Introduction the fields of study concerned with the waters of the Earth. Included are the sciences of hydrology, oceanography, limnology, and glaciology. In its widest sense hydrology encompasses the study of the occurrence, the… …
