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...

This study provides a simulation of mercury (Hg) transport in water and sediments the mining-impacted Ambalanga River located Upper Agno Subbasin Philippines. The Hydrologic Engineering Center - Modeling System (HEC-HMS) Water Quality Analysis Simulation Program (WASP) US Environmental Protection Agency (EPA) were coupled to handle both hydrologic modelling total Hg processes, respectively, for...

Abstract. Non-stop heavy rain had happened on 15th December of 2014, causing flood in Kelantan districts. Approximately 250 victims three districts were involved and relocated to six temporary relief centres. A hydrological model is designed simulate the runoff process for a catchment area. In this study, Hydrologic Engineering Center Modelling System (HEC-HMS) Rainfall-Runoff-Inundation (RRI) ...

Abha city is distinguished by urbanization, infrastructure, deepening watercourses, and changes in runoff flow which encourage flash floods the urban zones of many villages region. AlMahalah village prone to flooding due its geographic location near outlet convergence streams significant flow. The Geographic Information System (GIS), Remote Sensing (RS), Water Modeling (WMS), Hydrologic Enginee...

Estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. This study aimed to use the particle swarm optimization (PSO) algorithm for automatic calibration of the HEC-HMS hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...

arid and semi-arid regions of the world are confronted with limited water resources. a large part of iran is arid and semi-arid and rainfall in arid and semi-arid regions is typically meager, irregular and highly variable. this irregularity affects the hydrological cycle and water resources. investigating the hydrology of the arid and semi arid regions is essential to know this environment and ...

This study presents an evaluation of climate and land-use changes induced impacts on water resources Multan City, Pakistan. Statistical Down Scaling Model (SDSM) Geographical Information System (GIS) are used for change scenario spatial analyses. Hydrologic Engineering Center’s Hydraulic Modeling (HEC-HMS) model is rainfall-runoff simulation. The investigated results show significant in climato...

This work focused on the collection and preparation of data required for hydrological modelling Beht catchment area, which covers an area 4560 km 2 with a perimeter 414 km, by combining various spatial technologies, in particular geographical information systems (GIS), remote sensing, digital terrain models (DTM), order to prepare used flood forecasting. The methodology consists, at first, auto...
