Title: Estimation of Lake Evaporation and Potential Evapotranspiration
Abstract: Evaporation is one of the major losses from lakes and reservoirs, which requires to be accounted for water budgeting. When there is no instrumentation available for the direct measurement of lake evaporation, it becomes necessary to use models for its estimation. The Penman method is considered as one of the most reliable methods for estimating lake evaporation and is discussed in sufficient detail in the chapter. Besides estimating the evaporation loss from reservoirs, estimation of reference crop evapotranspiration or potential evapotranspiration is also required, which forms the basis of estimating the crop water requirement for irrigation planning. In this chapter, the Penman–Monteith method and ASCE-EWRI Standardized Penman–Monteith equation are discussed in detail along with the Hargreaves method for limited meteorological data availability.
