<p>Importing text file</p> <p><b>Nová stránka</b></p><div>:Slovak term: [[Slovenský termín]]<br /> # Groundwater recharge should be defined as the downward flow of water reaching the water table and replenishing groundwater resources (WHO 2006).<br /> <br /> ==Explanation==<br /> It is important to distinguish between infiltration of precipitation and groundwater<br /> recharge. When rain falls, some infiltrates into the soil. Much of this moisture is taken up<br /> by the roots of plants and is subject to evapotranspiration from the soil zone, and some<br /> becomes interflow drainage to streams and rivers. Only a part of the infiltration becomes<br /> recharge and moves deeper into the subsurface under gravity, and in arid and semi-arid<br /> areas this may be a very small proportion indeed (WHO 2006).<br /> <br /> ==Example==<br /> Now that the hydrological cycle has been interfered with as a result of human activities,<br /> recharge can also be derived from canals, reservoirs, irrigated land, water mains and<br /> sewerage systems in urban areas, mining waste, sewage lagoons -in fact - any artificial<br /> water body that is in connection with the subsurface. Artificial recharge, which is becoming<br /> an increasingly important resource management option, can also introduce water of<br /> different origin and quality into aquifers. This of course means that groundwater recharge<br /> is not always of the same good quality as infiltrating rainfall, which itself may be<br /> contaminated by acid rain or atmospheric acid deposition (WHO 2006).<br /> <br /> ==References==<br /> * WHO (2006) [http://www.who.int/water_sanitation_health/publications/protecting_groundwater/en/index.html Protecting groundwater for health.]<br /> <br /> ==Links==<br /> * [http://apps.who.int/thelexicon/ WHO — The Health and Environment Lexicon]<br /> <br /> [[Category:EN]]</div>
