Abstract. Floods are among the most destructive natural hazards in world, posing numerous risks to societies and economies globally. Accurately understanding modeling floods driven by extreme rainfall events has long been a challenging task domains of hydrologic science engineering. Unusual catchment responses flooding cause great difficulty predicting variability magnitude floods, as well prop...

In the present study, streamflow simulation capacities between Soil and Water Assessment Tool (SWAT) Hydrologic Engineering Centre-Hydrologic Modelling System (HEC-HMS) were compared for Huai Bang Sai (HBS) watershed in northeastern Thailand. During calibration (2007–2010) validation (2011–2014), SWAT model demonstrated a Coefficient of Determination (R2) Nash Sutcliffe Efficiency (NSE) 0.83 0....

  Application of gepraphic information system and image processing in evaluation of surface runoff of a watershed in recent years has increased greatly. In the study , the runoff curve number map was prepared using geographic information system (GIS)and Landsat Sattelite Images (ETM+)for two watersheds of Mansourabad in southern Khorasan province and Navroud in Gilan province based on the facto...

Abstract Discrepancies between estimated sediment and actual yields are large. The sedimentation often causes severe damage due to a lack of on-site measurement data in the current disaster prevention system. This paper presents robust early-warning system which statistical analysis used predict is conducted within context underlying physical mechanisms. three-phase employs collection, generati...

This paper concerns the design of a geographic location system to identify urban road sections susceptible runoff accumulation through analysis efficiency surface drainage networks. To this end, combination Geographic Information Systems (GISs) and stormwater models was proposed. First, GIS hydrology tools were employed generate all information required characterise catchments geometrically. Th...

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...

introduction: planning and management of water resource and river basins needs use of conceptual hydrologic models which play a significant role in predicting basins response to different climatic and meteorological processes. evaluating watershed response through mathematical hydrologic models requires finding a set of parameter values of the model which provides thebest fit between observed a...

This research evaluates the applicability of different types hydrological models to simulate discharge behavior scenarios in a northern Moroccan watershed, Oued Laou Watershed (OLW). In this context, an improved understanding runoff mechanisms through modeling OLW can assist hazard risk management and facilitate effective planning water resources. For that end, multitude were used perform very ...

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...
