Abstract: Research was performed that investigated the effect of survey technology and accuracy and reliability of hydraulic roughness estimates on the accuracy of computed water surface profiles. The survey technologies studied include field surveys, aerial surveys, and topographic maps as data sources for stream geometry cross-sectional definition. A Monte Carlo simulation strategy was applied to develop an array of computed accuracies, and Manning's coefficient reliability. Regression equations were derived for predicting profile errors as a function of survey technology, selected accuracy, Manning's roughness coefficient, and stream hydraulic properties.
