The hydrological simulation program FORTRAN(HSPF) is a comprehensive watershed model designed to simulate water quantity and quality *** is used widely throughout the *** discharge from a stream reach by HSPF is based mainly on function tables(ftables),which describe the relationship between surface area,stream stage,volume,and *** traditional method of FTABLE generation(using general stream cross-sections and the Manning equation or other discharge relationships) can be time-consuming and inaccurate when there are limited calibration stations and survey *** insights into generalized coupled stage/storage and stage/discharge relationships,however,offer the potential to improve both the speed and accuracy of compiling ftables and thus HSPF *** study tested the application of these insights in generating *** study domain included 18 gauging stations in a coastal plain environment on the Peace River watershed in West-Central *** the calibration of this model, wetlands were treated as reaches in HSPF with storage-attenuation *** the simulation period,the modeled daily flow and stage correlated well with observed data at all gauging stations along the Peace *** Nash-Sutcliffe efficiency and correlation coefficient computed using observed and simulated daily flows were 0.90 and 0.91,respectively,at the Peace River *** testing found that the new system for calibrating the ftables improved the model predictive ability and *** in un-calibrated station performance was also *** model parameters obtained in this study could potentially serve as reference values for model application in similar climatic *** may also have particular relevance in disaster management,as the simulation period extended over the hurricane season of 2004,and the model domain was within a high hurricane impact *** possible effects of hurricanes on discharge are also
