Effects of Watershed Management Practices on Some of Flood Characteristics Change in Haftan Watershed
Evaluation of watershed projects is one of the most fundamental problems in countries for future implementation planning and management of natural resources. In regard to lack of required equipment for monitoring and evaluation of watershed projects and investigation of management measures in watersheds, application of hydrologic models is an efficient tool for simulation of watershed behavior ...
متن کاملSustainability-Based Flood Hazard Mapping of the Swannanoa River Watershed
An integrated framework is presented for sustainability-based flood hazard mapping of the Swannanoa River watershed in the state of North Carolina, U.S. The framework uses a hydrologic model for rainfall–runoff transformation, a two-dimensional unsteady hydraulic model flood simulation and a GIS-based multi-criteria decision-making technique for flood hazard mapping. Economic, social, and envir...
متن کاملLandslide hazard zonation , mapping and investigation of triggering factors in Phewa lake watershed , Nepal
landslide also referred to as mass movement, slope failures, slope instability, and terrain instability is the mass movement, usually sudden, of soil and debris down a steep slope (Cruden, 1991). They are caused by a variety of factors such as heavy rains, earthquake ground shaking or geological forces. Different types of landslides move down slope at a wide range of speeds (Varnes, 1978). Most...
متن کاملRole of Watershed Management Practices on Flood Hydrograph Characteristics (Case Study: Kakhk Paired Watershed)
In the present study, the impact of watershed management practices on flood hydrograph characteristics was investigated using HEC-HMS model. In order to design, calibrate, and validate the model, data from a representative paired watershed (Kakhk Watershed, Khorasan Razavi Province, Iran) was collected and field surveys were performed to have the dataset further completed. Results of paired sam...
متن کاملImpact of Watershed Management activities on flood hydrograph Using HEC-HMS Model (Case Study: Ramyan Watershed)
Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...
