Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

Numerous studies have shown the positive effects of rosmarinic acid on the nervous system. Rosmarinic acid as a herbal compound with anti-inflammatory effects can prevent the destructive effect of inflammation on the nervous system. Furthermore, various studies have emphasized the advantages of three dimensional (3D) culture over the two dimensional (2D) culture of cells. In this study, thermos...

studying risk and frequency analysis of flood is done in order to design structures located in floody lands. in hydrological and water resources engineering projects, first of all, we should determine frequency of this phenomenon- their return period. in this research, the method of planning, the cumulative freguency curve is explained and probability and return period and errors concerning sma...

In designing civil engineering structures use is made of probabilistic calculation methods. Stress and load parameters are described by statistical distribution functions. The parameters of these distribution functions can be estimated by various methods. An extensive comparison of these different estimation methods is given in this paper. The main point of interest is the behaviour of each met...

assessment of watershed management activities is one of the main subjects for future planning of practical projects and natural resources management. due to the lack of any tool for assessment of watershed processes in many cases, distributed hydrological models can be useful. the purpose of this study was evaluation of watershed management activities in kan watershed by hec-hms (hydrologic mod...

The paper presents a Multidisciplinary Decision Support System (MDSS) to analyse rainfall-induced shallow flowslides on steep slopes covered by pyroclastic deposits. This system proposes an approach to provide technical information to the agencies responsible for civil protection and land management about the link between forecasted rainfall and the effects in terms of infiltration, slope stabi...

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–...

In order to examine the relationship between rainfall return periods and flood periods, design storm approach is compared rainfall–runoff continuous simulation frequency analysis approach. The former was based on event-based hydrological simulations, while latter simulations analysis. All were undertaken employing HEC-HMS software. For analysis, Generalized Extreme Value (GEV) probability distr...
