Threshold Categories
-
When a forest is disturbed, surface runoff may increase, generating surface runoff and sediment delivery. In some cases, such disturbance can also release nutrients like phosphorus to runoff and subsurface lateral flow, adversely affecting offsite water quality. If there is no forest management, then the risk of wildfire is increased, as is the probability of elevated erosion rates much greater than those associated with disturbances from forest management.

| 08/13/2017 9:43 PM | Kiara Cuerpo-Hadsall | Objectives: The objective of this project was to provide temporal and spatial predictions of nutrient and sediment loadings at the hillslope scale for prescribed fire using an optimized Watershed Erosion Prediction Project (WEPP) model. Optimization was performed through calibration and validation efforts using locally-measured data for WEPP’s most sensitive erodibility parameters (hydraulic conductivity, interrill erodibility, and bulk density); runoff quantity and quality; and sediment yield and composition. Validation was evaluated through quantitative measures of goodness of fit. |

| 08/13/2017 9:40 PM | Kiara Cuerpo-Hadsall | Management Implications: This project, while specific to prescribed fire, optimized the WEPP model with local data, with results that are expected to be applicable beyond the scope of this project, such as improving WEPP’s application to other non-urban fire and non-fire related sources and its application to evaluate best management practices at the necessary smaller-scales for siting, design, cost-benefits, and long-term effectiveness. |
