Abstract
Abstract: Knowledge of bankfull discharge (Qbf) is essential for planners, engineers, geomorphologists, environmentalists, agricultural interests, developments situated on flood prone lands, surface mining and reclamation activities, and others interested in floods and flooding. In conjunction with estimating Qbf, regionalized bankfull hydraulic geometry relationships, which relate Qbf and associated channel dimensions (i.e., width, depth, and cross‐section area) to drainage basin area (Ada), are often used. This study seeks to improve upon the common practice of predicting Qbf using Ada exclusively. Specifically, we hypothesize that predictions of Qbf can be improved by including estimates of the 2‐year recurrence‐period discharge (Q2) in regression models for predicting Qbf. For testing this hypothesis, we used Qbf estimates from 30 reports containing data for streams that span 34 hydrologic regions in 16 states. Corresponding values of Q2 and Ada were compiled from flood‐frequency reports and other sources. By comparing statistical measures (i.e., root mean squared error, coefficient of determination, and Akaike’s information criterion), we determined that predicting Qbf from Q2 rather than Ada yields consistently better estimates of Qbf. Other principal findings are (1) data are needed for at least 12 sites in a region for reliable hydraulic geometry model selection and (2) an approximate range of values for Qbf/Q2 is 0.10‐3.0.
