Lake Typology and classification system #146

Open pbuttigieg opened 9 years ago

pbuttigieg commented 9 years ago

During the SONet Lake workshop (2015-06-04), it was stated that most classification systems are based on fairly standard textbook knowledge

"What's in the water" Trophic status Oxygenation Salinity Carbonate concentration Ecological communities or presence/absence of invasive Potability

"the lake itself" Mixing regime (mostly done) Lake origin Permanence Connectivity Lake use ([used for, suitable for] recreation, hydropower, flood control) link to ecosystem Management regime Spill point, elevation of the spillway (for reservoirs) conservation pool elevation elevation depth size water residence time Interestingly, morphometry not used for classification very often, but it is used. convex vs concave

"around and encompassing the lake" climate zone / environmental conditions land use /land cover catchment area or catchment area to lake area ratio soil types, geological features rainfall buffer zone vs watershed

lake origin (oxbow, tectonic, glacial, man-made, volcanic, crater, thermokarst);--see also http://www.esf.edu/efb/schulz/Limnology/LakeOrigin.html
