Basin

Form indicating the overall configuration of the water body. It can be of the following types: "L", in the case of shallow lakes with thermal stratification of little extent and/or unstable (polymictic lakes) and a heavily dominant coastal zone; "P" in the case of deep lakes with a stable thermal stratification (monomictic or dimictic lakes) and a reduced coastal zone; "LP" in the case of lakes with both a stable stratified deep zone (monomictic or dimictic) and a wide coastal area, the basin can be symmetrical or asymmetrical.
