Abstract: This research developed methods to estimate the total phosphorus flux into a reservoir. Chiu's models for calculating the distribution of velocity and sediments over a channel cross-section were combined in this study. Models were applied to estimate the total phosphorus flux in inflows of Te-Chi Reservoir and Feitsui Reservoir in Taiwan. The model results compare favorably to the vertical distribution of observed data in velocity, sediments, and dissolved and particulate phosphorus concentrations. Using long-term streamflow data (hourly or daily), the annual total phosphorus loading rates can be estimated by the models developed herein. Those loading rates are essential for water quality and eutrophication modeling in the reservoir.
