5284306956	surface runoff	Precipitation that does not infiltrate the ground or return to the atmosphere by evaporation.	14
5284306957	watershed	The land area that supplies water to a river system. An ecosystem where all water runoff drains into a single body of water	15
5284309824	floodplain	an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.	16
5284314471	channelization	An engineering technique to straighten, widen, deepen, or otherwise modify a natural stream channel.	17
5284321407	levees	Barriers composed of sediments made on either side of a river due to flooding.	18
5284323341	consumptive use	Freshwater that is removed from a particular aquifer or surface water body and is not returned to it. Used for agricultural, industrial, & households (drinking water)	19
5284340324	non consumptive use	Fresh water use in which water from an aquifer or surface body water is not removed or is removed temporarily and then returned	20
5284384372	desalination	A process of removing salt from ocean water	21
5284388165	distillation	A process that separates the substances in a solution based on their boiling points	22
5284391079	reverse osmosis	A technique for purifying water by forcing it through a semipermeable membrane.	23
5284397516	artesian well	water rises on its own because of pressure within an aquifer	24
5284397517	reliable run off	Surface runoff of water that generally can be counted on as a stable source of water from year-to-year.	25
5284401219	withdrawal	freshwater removal	26
5284404756	center pivot irrigation	An irrigation system comsisting of a spray arm several hundred meters long supported by wheels pivoting around a central well from which water is pumped.	27
5284410503	water hot spots	In these areas, competition for scarce water to support growing urban areas, irrigation, recreation, and wildlife could trigger intense political and legal conflicts; where water is scarce.	28
5284416455	hydrological poverty	Serious water shortages are emerging as the demand for water in many countries simply outruns the supply forcing people to live in poverty.	29
5284418551	shantytowns	Unplanned slum development on the margins of cities, dominated by crude dwellings and shelters made mostly of scrap wood, iron, and even pieces of cardboard.	30
5284421834	land subsidence	due to rapid rate of withdrawing large amounts of groundwater from sand and rock in aquifers; leads to land above settling and sinking over time	31
