Efficient Data Assimilation Method for Optimizing Prediction of Flow Field and Sediment Transport in Open Channel

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter ks in a shallow‐water equation model (via the momentum ...

The Arkansas Irrigation Scheduler

World Environmental and Water Resources Congress 2009, 2009
In the US Mid-South, annual rainfall is generally sufficient for limited crop production, but periods of drought during the growing season make irrigation essential for optimum yields. However, factors such as cloudy weather, rainfall, and temperature swings caused by the movement of weather fronts all complicate irrigation scheduling.
