Evapotranspiration (ET) is one of the largest components of the water balance in agricultural systems. Therefore, measurement or modeling of ET is an indispensible part of agricultural water management or managing risks associated with moisture excess or deficit. Posters that present applications of ET measurement or modeling as part of water management or risk management schemes are welcome. Water/risk management applications of ET measurement or modeling may include water rights administration, interstate compact negotiation/compliance, irrigation scheduling, estimation of water use by invasive species, protection of endangered species, monitoring drought and food security, hydrologic modeling, and crop modeling, among others. This session will include a graduate student poster competition.
