Role 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 کاملDetermining the effect of physical characteristics on flood hydrograph (Case study: Western section of Jazmurian Basin)
Abstract Flood causes great and uncompressible damage to people’s life and properties as well as environment each year in Iran. This research was carried out at the west section of Jazmurian basin that placed in the southeast of Iran. In this research physical characteristics such as area (A), perimeter (Pr), average elevation of basin (av.e), average slope (av.s), gravelious coefficient (G),...
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 ...
متن کاملEvaluation of geomorphology method application for flood Hazards risk classification using Fuzzy Logic (Case study: Ojan Chay drainage basin)
Past decades damage by floods in Iran and on the other of the world has shown that we have still much work to do to cope with this problem. Hence, the study of these events and development of more effective adaptation and mitigation policies has become a priority, in other parts of the globe. First step in achieving flood risk assessment is data collection. Availability, suitability and quality...
متن کاملبرآورد هیدروگراف واحد مصنوعی با استفاده از تحلیل منطقه‌ای سیلاب و پارامترهای ژئومورفولوژیکی (مطالعه موردی: حوضه‌های آبخیز مارنج و کانی‌سواران، کردستان)
Estimation of flood hydrograph is of necessities in hydrological studies such as flood mitigation projects. This estimation in un-gauged watersheds is usually taken place using geomorphological characteristics of watersheds. The objective of this research is to estimate synthetic unit hydrograph using regional flood frequency analysis and geomorphological parameters of watersheds. 1-hour and 2-...
