A methodology is presented for extracting topographic, topologic, and hydrologic information, from the digital spatial data of a hydrologic system, for hydrologic modeling with HMS. Methods for stream and watershed delineation from digital elevation models are presented. After vectorizing the raster-based stream segments and watersheds, navigation fields are added to their tables to support top...

The current study presents the first attempt to investigate November 2019 catastrophic flash flood in Olympiada (North Greece) under an operational forecasting and monitoring context, based on mesoscale weather research (WRF) model integrated multi-satellite retrievals for global precipitation measurement (GPM-IMERG) algorithm. When evaluated against ground-based rainfall measurements, WRF show...

Abstract Frequency of flash floods and droughts in the Mediterranean climate zone is expected to rise coming years due change its climate. The assessment impact at a basin scale essential for developing mitigation adaptation plans. This study analyses variation hydrologic regime small river (the Kalloni Lesvos Island, Greece) by examination possible future scenarios. response was simulated base...

Abstract Floods are one of the extreme events and widespread natural disasters that significantly affect civil infrastructure livelihood people. Recently, climate change has affected rainfall pattern increased flood worldwide, especially in India. Therefore, it become essential to map potential inundation regions for various future developing appropriate mitigation management strategies. This s...

Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...

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–...

Many cities have been built along large rivers. The rivers can provide a source of drinking water, act as receiving water for treated effluent, provide navigation for shipping, and other beneficial uses. However, the city must also be protected from flooding due to the close proximity to the river. Hydrologic analysis plays a crucial role in the development of plans for protecting a river city....

Flash floods cause great harm to people’s lives and property safety. Rainfall is one of the main causes flash in small watersheds. The uncertainty rainfall events results inconsistency between traditional single pattern actual process, which poses a challenge for early warning forecasting floods. To carry out effective flood forecasting, this paper proposes novel by coupling total peak intensit...
