  • Surface Water
  • Pertains to all water present above the substrate or soil surface including water contained in an ocean, river, stream, lake, pond, lagoon, or impoundment reservoir.
  • Land Use/Land Cover
Abstract from DBPedia
    Surface water is water located on top of the Earth's surface such as rivers, creeks, and wetlands. This may also be referred to as blue water. The vast majority is produced by precipitation and water runoff from nearby areas. As the climate warms in the spring, snowmelt runs off towards nearby streams and rivers contributing towards a large portion of our drinking water. Levels of surface water lessen as a result of evaporation as well as water moving into the ground becoming ground-water. Alongside being used for drinking water, surface water is also used for irrigation, wastewater treatment, livestock, industrial uses, hydropower, and recreation. It is recorded by the Environmental Protection Agency (EPA), that approximately 68 percent of water provided to communities comes from surface water. For USGS water-use reports, surface water is considered freshwater when it contains less than 1,000 milligrams per liter (mg/L) of dissolved solids. There are three major types of surface water. Permanent (perennial) surface waters are present year round. This includes rivers, swamps, and lakes. Semi-permanent (ephemeral) surface water refers to bodies of water that are only present at certain times of the year including areas such as creeks, lagoons, and waterholes. Man made surface water is water that can be continued by infrastructure that humans have assembled. This would be lakes, dams, and artificial swamps. The surface water held by dams can be used for renewable energy in the form of hydropower. Hydropower is the forcing of surface water sourced from rivers and streams to produce energy.

    表流水(ひょうりゅうすい、英語: Surface Water)とは、河川や湖沼の水のように完全に地表面に存在している水のことで、特に停滞していない水(流れを確認することが可能である水)のことをいう。地表水とほぼ同義であるが、地表水が一部の湖沼水や水たまりなどの停滞した水を含むのに対して、表流水には停滞した水は含まない。
