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...

The hydrological response of a medium-sized watershed with both rural and urban characteristics was investigated through event-based modeling. Different meteorological event conditions were examined, such as events high precipitation intensity, double peak, mainly normal to wet antecedent moisture conditions. Analysis the hydrometric features conducted by comparing different rainfall time inter...

Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

With advancements in computational technology, data assimilation techniques, high-resolution remote sensing, and complex climate models, numerous precipitation products are available with different spatiotemporal resolutions; however, their evaluation, especially the Himalayan region, is unexplored. Therefore, this study attempts to assess four sources (gridded observation dataset, reanalysis, ...

Rainfall-runoff simulation is vital for planning and controlling flood control events. Hydrology modeling using Hydrological Engineering Center—Hydrologic Modeling System (HEC-HMS) accepted globally event-based or continuous of the rainfall-runoff operation. Similarly, machine learning a fast-growing discipline that offers numerous alternatives suitable hydrology research’s high demands limitat...

[1] Despite significant recent developments in computational power and distributed hydrologic modeling, the issue of how to adequately address the uncertainty associated with hydrological predictions remains a critical and challenging one. This issue needs to be properly addressed for hydrological modeling to realize its maximum practical potential in environmental decision-making processes. Ar...

In the current study, a novel method is proposed to analyze simultaneous impacts of non-stationarity in hydrological time series and land-use changes urban areas predict future floods probable damage. For this purpose, rainfall frequency analyses were conducted for two periods (first: 1979–2009 second: 1979–2019), results compared. Then, hydrologic modeling catchment was carried out using HEC-H...

In component-based modeling, a complex system is represented as a series of loosely-integrated components with defined interfaces and data exchanges that allow the components to be coupled together through shared boundary conditions. Although the component-based paradigm is commonly used in software engineering, it has only recently been applied for modeling hydrologic and earth systems. As a r...
