Estimating actual evapotranspiration (ET) is essential for crop and groundwater management.<\/p>\n\n\n\n

Estimation of plant water requirement allows for optimization of irrigation, as well as better estimation of groundwater recharge.<\/p>\n\n\n\n

Unfortunately we do not have direct measurements of evapotranspiration at the watershed scale, so many models are developed.<\/p>\n\n\n\n

In a first step, I will show the influence of the spatial and temporal distribution of evapotranspiration and recharge on the outflow of a karst hydrosystem.<\/p>\n\n\n\n

In a second step, a data assimilation approach is used to explore the uncertainty of evapotranspiration at the field scale.<\/p>\n\n\n\n
