ABSTRACT
Two of the important parameters needing evaluation in development of irrigation and storage facilities for reclaimed water irrigation systems are losses through the process of evaporation and gains from precipitation. In fact this chapter could appropriately be titled “Net Losses in Surface-Atmosphere Interactions.” In this chapter procedures are developed for estimating expected losses of water through transpiration (T) by plants and evaporation (E) from plant, soi1, or pond surfaces. The combined 1oss for a cropped surface is commonly referred to as evapotranspiration (ET). Extensive precipita tion records are already available.
