| The proposed alignment of the Appalachian Corridor H section from Davis to Bismarck passes through Beaver Creek watershed, Tucker County, West Virginia, which was heavily affected by the historical mining, deteriorating the water quality conditions of the Beaver Creek. To improve the water quality of Beaver Creek, identification of the sources of impaired waters and the conveyance of these flows into passive treatment facilities for remediation has been proposed. To aid in the design of these treatment facilities, a baseline hydrology description through the hydrologic modeling of the watershed with the aid of rainfall-runoff models was proposed. The watershed modeling was done with the help of two hydrologic models---the NRCS Technical Release - 20 Model (TR-20) and Hydrologic Engineering Center - Hydrologic Modeling System (HEC-HMS) Program. The main objective of this study was to estimate the peak discharges and obtain runoff hydrographs at various locations along the Beaver Creek watershed for return periods ranging from 1-year to 100-years. This study presents a comparison of both the methods used and recommends peak flow predictions, which can be used in the design of the passive treatment facilities. |
