Information retrieved from in-situ and spaceborne observations can be used to develop hydro(geo)logic models . These may aim to understanding and forecasting the water balance and its components, flooding patterns and risk, irrigation water needs, drought, groundwater probability mapping, hydrometeorological models.
Water balance, precipitation, evapotranspiration
