Abstract: Twenty‐one drainage lysimeters were installed in 1988 to measure water balance parameters for citrus trees. The lysimeters were designed to simulate the high water‐table conditions that exist for the more than 150,000 ha ...

Abstract: An ensemble Kalman filter (EnKF) estimates the error statistics of a model forecast using an ensemble of model forecasts. One use of an EnKF is data assimilation, resulting in the creation of an increment to the first-guess ...

Abstract: Consideration of flows in which the rate of change of momentum is much smaller than the Coriolis force suggests that the advected quantity momentum may be approximated by its geostrophic value but that trajectories cannot ...

Abstract: Satellite observations of temperature, water vapor, precipitation and longwave radiation are used to characterize the variation of the tropical hydrologic and energy budgets associated with the El Niño?Southern Oscillation ...

Abstract: A decision framework is presented for assessing the value of ground-water sampling within the context of ground-water management under uncertainty. The framework couples two optimization models—a chance-constrained ...
