Water Evaporation in Areas of High Aridity

This study was conducted to estimate the evaporation rate in an arid region; namely the Dead Sea. Estimation of evaporation helps in planning, operation and management of water resources. Direct measurement of evaporation rates on daily basis extended for one year. Daily energy-budget and Penman s evaporation rates were determined from available data to quantify evaporation rates and to assess the assumptions associated with Penman s method for use in an area characterized as arid. An attempt was made to correlate the evaporation rate with the meteorological data affecting it. A procedure was developed and found suitable for calculating the evaporation rate from the sea site and other similar regions of high aridity
