Comparison of Linear and Non-Linear Hydrologic Flood Routing Models on Four California Rivers and Relationship of Model Parameters to Channel Physical Characteristics

摘要

The relative performance of three Flood Routing models in natural systems has been investigated. Traditional Muskingum, Non-Linear Muskingum and Linear Least-Square models have been fitted to historic streamflow records on four California rivers. The simple Linear Least - Squares model, which fits the Muskingum model is found to be most accurate in predicting downstream flows for a variety of river and flood types. The rel of this model results from a lack of constraints and subjectivity imposed in the formulation of the Muskingum and Non-Linear models.
