Abstract
The rating curve method is used to quantify daily sediment and phosphorus loads to Lake Lanier. The
sediment rating curve was constructed using discharge
and suspended sediment records for the Chattahoochee
River and tributaries. Bedload sediment transport is not
included in the sediment rating curve. The daily variability of sediment concentration is reconstructed using the
discharge-sediment rating curve. Total phosphorus concentrations are strongly correlated with sediment concentrations. This approach is superior to other sediment and
nutrient yield models (e.g., the Universal Soil Loss Equation) because the seasonal and annual estimates provided
by these approaches are not compatible with the need to
model lake water quality dynamics on a daily basis.
