Effectiveness of stormwater management practices in protecting stream channel stability

Hypotheses

1. Channel instability in Minebank Run is caused by high shear stresses generated during even relatively frequent storm events.
2. Retrofitting the Minebank Run watershed with additional watershed stormwater controls will reduce channel incision and bank failure (will compare environmental site design (ESD) only, traditional downstream controls only, and combination of both).
3. Had Minebank Run been developed with ESD channel incision and degradation would have 1) been prevented, or 2) been reduced.
4. Current channel degradation in tributaries to Little Seneca Creek are the result of recent large magnitude storm events, which are typically not well controlled by ESD.
5. Had the Clarksburg watershed been developed using traditional stormwater control measures (SCMs), more extensive channel degradation would have occurred.
6. A combination of ESD controlling small storms and SCMs controlling larger events is necessary to protect stream channels against erosion.
