Flood Risk Zoning of Satluj River Basin, Himachal Pradesh, India

摘要: Increasing intensity and frequency of rainfall coupled with gradual retreating glaciers due to climate change in Himalayan region likely increase the risk floods. A better understanding zones which are vulnerable flood disasters can be evolved from detailed studies on slope, geomorphology land use/ cover pattern. Information these parameters is an important input for identification areas. Flood maps provide useful information about places that may at flooding. It offers a cost-effective solution planning, management mitigation strategies risky Traditional methods mapping based ground surveys aerial observations, but when phenomenon widespread, such time consuming expensive. The possible combination DEM other area using overlay operation method within Geographical System (GIS) platform lead derivation spatial association between various could used predict zones. study i.e. Satluj River Basin has been broadly divided into five viz., very low, moderate, high helped differentiate areas different intensities flood. zone covers only 3.25 % total area, while low 13.63 %. falls constitutes 9.52 basin area. Domain moderate 30.66 But maximum river constituted by 46.19 Identification will help timely adopting adaptation measures. Preparation zoning also helps regulating indiscriminate unplanned use practices
