WebMean annual evaporation estimates were determined for 30 lakes by use of a numerical model (Morton, 1979) and by use of an evaporation map prepared by the U.S. Weather Service (Kohler et al., 1959). These estimates were compared to the reported value of evaporation determined from measurements on each lake. Various lengths of … WebOct 1, 1983 · 1. INTRODUCTION Operational estimates of lake evaporation must rely on readily available information and in practice this means climatological data or pan evaporation data that have been observed in the land environment. There are several problems associated with the use of such observations.

WebSalt evaporation pond. A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The Salt pans are shallow and expansive, allowing sunlight to penetrate and reach the seawater. Natural salt pans are formed through geological processes, where water evaporating, leaving behind salts deposits. WebPrevious estimates of average annual evaporation from the lake formed by the High Dam at Aswan, Egypt, fall in the range from 4.65 mm d−1 to 7.95 mm d−1. The difference between these limits, more than 7 billion m3 yr−1 at the highest storage level, is nearly one-eighth the share by treaty of Egypt, and more than one-third of the share of the Sudan.
