USE OF STATE ESTIMATION TECHNIQUES IN WATER RESOURCE SYSTEM MODELING1
Dennis P. Lettenmaier, Stephen J. Burges · JAWRA Journal of the American Water Resources Association · 1976
ABSTRACT. A relatively straightforward illustration of the potential uses of State Estimation techniques in water resources modeling is given. Background theory for Linear and Extended Kalman Filters is given; application of the filter techniques to modeling BOD and oxygen deficit in a stream illustrates the importance of model conceptualization, model completeness, uncertainty in model dynamics and incorporation of measurements and measurement errors. Potential applications of state estimation techniques to measurement system design; model building, assessment and calibration; and data extension are explored.
