| 摘要： | The Cheat River, primarily located in northeast West Virginia, experiences majorflooding events that negatively impact nearby communities. Poor water quality dueto acid mine drainage and excess sediment loads during flood events threaten thehealth of communities and numerous animal species who depend on the Cheat as aprimary water source. Communities in the Cheat River watershed are confrontedwith floods that can destroy housing, key infrastructure, and crops, and alsofurther pollute the river. A warming climate is predicted to increase precipitationand storm severity in the region, which could increase flood frequency in thewatershed. The team partnered with the Friends of the Cheat (FOC), anorganization that has historically focused on mitigating acid mine drainage in theriver and has recently begun to focus on proactive flood mitigation. UtilizingLandsat 5 Thematic Mapper (TM), Landsat 8 Operational Land Imager (OLI), andShuttle Radar Topography Mission (SRTM) data, the team conducted a climatologytime series analysis, monitored changes in land use and land cover change, andcreated flood risk and vulnerability maps to improve FOC’s flood mitigation efforts.To calculate the change in precipitation and temperature, the team used theequations of the linear trend lines based on annual averages of Preston andTucker counties and averaged the results. These results indicated thattemperature has increased by about 1.5°C and precipitation has increased by 4.2inches between 1970 and 2020, while monthly river discharge has become morevariable. At the same time, there were no detectable trends in land cover at thecounty level. Communities near Parsons, Masontown, Reedsville, and Eglon areamong the most vulnerable to flood events based on the flood vulnerabilityanalysis. |
