In this study, we conducted flood mapping of a hypothetical dam break by coupling the Hydrologic Engineering Center’s Modeling System (HEC-HMS) and River Analysis (HEC-RAS) models under different return periods inflow. This study is presented as case on Kesem embankment in Ethiopia. Hourly hydrological meteorological data high-resolution land surface datasets were used to simulate design floods...

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...

A hydrometeorological forecasting system has been operating at the Institute of Marine Biological Resources and Inland Waters (IMBRIW) Hellenic Centre for Research (HCMR) since September 2015. The consists Advanced Weather Forecasting (WRF-ARW) model, WRF-Hydro hydrological HEC-RAS hydraulic–hydrodynamic model. provides daily 120 h weather forecasts focusing on Greece (4 km horizontal resolutio...

Green porous and ecofriendly scaffolds have been considered as one of the potent candidates for tissue engineering substitutes. The objective of this study is to investigate the biocompatibility of hydroxyethyl cellulose (HEC)/silver nanoparticles (AgNPs), prepared by the green synthesis method as a potential host material for skin tissue applications. The substrates which contained varied conc...

in many flood control projects, watershed management and water resources development, calculation of the river flow discharge is of the paramount importance which requires a comprehensive hydrological modeling of the region of interest. in this respect, lack of the existence of hydrometric and meteorology measuring stations in most of watersheds, has caused numerous problems in development and ...

In this study, a novel fibrous membrane of hydroxyethyl cellulose (HEC)/poly(vinyl alcohol) blend was successfully fabricated by electrospinning technique and characterized. The concentration of HEC (5%) with PVA (15%) was optimized, blended in different ratios (30-50%) and electrospun to get smooth nanofibers. Nanofibrous membranes were made water insoluble by chemically cross-linking by gluta...

Levee breaches are some of the most common hazards in world and cause loss lives, livelihoods, property destruction. During 2010 flood Pakistan, devastating breach occurred at Tori on right bank Indus River, downstream Guddu Barrage, which caused residual floods northern Sindh adjoining regions Balochistan province. In this study, 2D unsteady flow modeling performed for computed inundation by c...

In this study, randomly oriented hydroxyethyl cellulose/polyvinyl alcohol (HEC/PVA) nanofibers were fabricated by electrospinning. The blend solutions of HEC/PVA with different weight ratio of HEC to PVA were prepared using water as solvent to fabricate nanofibers. These nanofibrous scaffolds were coated with bone-like apatite by immersing into 10x simulated body fluid (SBF) for different time ...

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...
