Often, Paleolakes are identified based on relict lacustrine landforms such as coastal landforms that form recognizable relict shorelines, referred to as paleo-shorelines. graphically based classification schemes is to re-duce variability based on spatial covariance in cli-mate and geology, and thus topography, climax veg- etation, hydrology, and soils. Classification of these is a function of water table location within the subsurface, its structure and hydraulic conductivities into two namely; Confined Aquifers and Unconfined Aquifers and then … Introduction The measure of the rate at which work is performed is called “productivity”. Expression of productivity in terms of lake volume eliminates the problems found using integral productivity both in shallow lakes and in those with low kw, and therefore, with potentially deep euphotic zones.
