Computer program HEC-1, a precipitation-runoff model widely used throughout the United States, includes the capability to estimate automatically any of twelve parameters necessary to model the precipitation-runoff process and the channel routing process. The parameter estimation scheme employs Newton's method to minimize a weighted sum of squares of differences between observed and computed hydrograph values. Applications of this parameter estimation procedure are presneted, and typical steps of the procedure for deterimining optimal parameter estimates are outlined. Recent efforts to improve the estimation algorithm and recent use of the calibration capability to update sequentially parameter estimates in a flood forecasting application are discussed. (Author).

"The importance of selection of parameter ranges is currently given little attention in the calibration process, but even with the superior search capability of GOMs, inflated search spaces can frustrate their searches and may lead to inferior parameter estimation. Several inequalities relating model parameters with the hydrologic data were developed, which when coupled with the SCE method, significantly improved the GOM performance. This modified SCE method appeared less sensitive to the problem of parameter range specification. A method for formulating these constraints was demonstrated on synthetic data and a procedure for its application to real data was done using data from two tropical watersheds." --

Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 6. During the past four decades, computer-based mathematical models of watershed hydrology have been widely used for a variety of applications including hydrologic forecasting, hydrologic design, and water resources management. These models are based on general mathematical descriptions of the watershed processes that transform natural forcing (e.g., rainfall over the landscape) into response (e.g., runoff in the rivers). The user of a watershed hydrology model must specify the model parameters before the model is able to properly simulate the watershed behavior.

Computer program documentation is important to proper model use. Common causes of poor documentation include: organizational negligence and lack of capability, difficulty in clearly communicating a description of the model, motivation on the part of the modeler to prepare good documentation, absence of examples of good documentation, inadequate time funds, staff.
