Floods are considered as most destructive among all natural hazards which impose lots of damages on human societies. Hence, it is important to estimate such damages and losses and to determine flood impact areas for management plans. HEC-FIA software as a new model (Sep. 2012) was used in Ghohrood and Ghamsar watershed basins to estimate flood-driven losses and impacts. In this model, HEC-RAS a...
Abstract The construction of river training structures has a local influence on hydraulic and sediment regimes. River is simply to modify the dimensions patterns channels, bars, pools. Many scientists have applied developed methods identify suitable techniques for training. In this paper 60 scientific papers were reviewed, through review, researchers divided according method using model problem...
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract This paper presents a case study to estimate peak discharges of extreme flood events of Neckar River in southwestern Germany during the 19th century. It was carried out within the BMBF research project RIMAX (Risk Management of Extreme Flo...
سالانه در نقاط مختلف جهان، جان و مال بسیاری از مردم در اثر وقوع سیل به مخاطره می¬افتد. توسعه مناطق روستایی و شهری در حاشیه رودخانه¬ها، بستر و حواشی دشت¬های سیلابی بدون شناخت و توجه به شرایط هیدرولوژیکی و دینامیکی رودخانه¬ها و قسمت¬های بالادست حوزه که موجب افزایش خطر سیلاب و خسارات جانی، مالی و زیربنایی ناشی از آن می-شود، توسعه را با ناآگاهی مواجه می¬سازد. از این رو اهمیت برآورد خسارات ناشی از س...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
Abstract This research aims to map flood inundated areas under changing climate in the Boyo watershed of Southern Ethiopia. A semi-distributed physically based Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) and Center-River Analysis (HEC-RAS) were used simulate events maps, respectively, for scenarios. The bias-corrected data four models baseline (1976–2005), mid-term (2041–...
The U.S. Army Corps of Engineers’ Hydrologic Engineering Center’s River Analysis System (HEC-RAS) is a widely used software application for performing one-dimensional and two-dimensional steady and unsteady flow river hydraulics calculations, sediment transport-mobile bed modeling, and water quality analysis. User’s of HEC-RAS have often unique applications including the coupling with other sof...
