Technologies such as aerial photogrammetry allow production of 3D topographic data including complex environments such as urban areas. Therefore, it is possible to create High Resolution (HR) Digital Elevation Models (DEM) incorporating thin above ground elements influencing overland flow paths. Even though this category of big data has a high level of accuracy, there are still errors in measur...

A rainfall regionalization method based on variation coefficient was applied with a variant in the construction of flash flood hyetographs several return periods using shape historical event that occurred September 2021 Tlalnepantla River basin, Mexico, caused severe damage to population and its infrastructure few hours. The simulated semi-distributed model free software HEC-HMS order obtain ou...

Abstract. Detention dams are one of the most effective practices for flood mitigation. Therefore, impact these structures on basin hydrological response is critical management and design control structures. With aim providing a mathematical framework to interpret effect flow systems river dynamics, functional relationship between inflows outflows investigated derived in closed form. This allowe...

Abstract Flood events are the most commonly occurring natural disaster, with over 5 million properties at risk in UK alone. Changes global climate expected to increase frequency and magnitude of flood events. hazard assessments, using projections as input, guide policy decisions engineering projects reduce impact large return period Probabilistic modeling is required take into account uncertain...

Dam overtopping failure and the resulting floods are hazardous events that highly impact inundated areas less predictable. The simulation of dam breach flood wave propagation is necessary for assessing hazards to provide precautions. In present study, a two-dimensional HEC-RAS model was used simulate from hypothetical Al-Udhaim on River, Iraq, dam-break along 100 km downstream site scenario. ma...

Riparian cottonwood (Populus deltoides) forests form the one of the most extensive deciduous forest ecosystems in arid regions of the western United States. However, cottonwood populations are threatened by flow alteration and channel degradation caused by dams, water diversions, and groundwater pumping. We developed a stochastic, densitydependent, population model to (1) consolidate informatio...

Hydrological modeling is a widely used approach for estimating the hydrological response of basin to precipitation. Floods are among most catastrophic natural disasters in small urban watersheds, inflicting loss life, massive property destruction, and severe danger economy. As result, appropriate can be useful tool preventing mitigating such flood hazards. Despite this, flash prediction remains...
