The Rippl method is a reservoir sizing method where the size of the reservoir is
equal to the maximum cumulative difference between inflows and outflows. The
Rippl diagram shows the cumulative net volume in the reservoir.
Lake with a moderate supply of plant nutrients. Has moderate chlorrophyll-
a concentration, moderate algaie growth, depleted hypolimnion dissolved
oxygen concentration, low pollution, and limited resource multiuse
impairment.
Excessive drying out of the soil. It's bad because clay loses it's low-permeability
properties when it's very dry.
Air stripping is the transferring of volatile components of a liquid into an air
stream. It is an environmental engineering technology used for the purification of
groundwaters and wastewaters containing volatile compounds.
