Ponding euthophication
WebEutrophication in marine, coastal and estuarine ecosystems is a consequence of nutrient over-enrichment, mostly inputs of nitrogen, phosphorus and organic matter from land-based sources (agriculture, urbanisation), marine activities (aquaculture) and from atmospheric deposition (e.g. from road transport and shipping emissions to the air). WebThe deflected shape crosses the horizontal datum in the region of L/16, creating negative slope and a “bowl” at the low end. A “bowl” naturally retains water and restricts free drainage or water discharge. Ponding or water retention should be expected toward the low end of a plane designed to a ¼ in 12 slope.

Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity".
