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...

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...

A thermosensitive polymer can be held liquid before being injected to deliver living cells or therapeutic agents and formed monolithic gels when injected in vivo. In this study, chitosan-based thermosensitive hydrogels were prepared, characterized and the biocompatibility for culturing mice bone mesenchymal stem cells (BMSC) on 2D films and within 3D hydrogel were investigated. The gelation tem...

Woodland planting is gaining momentum as a potential method of natural flood management (NFM), due to its ability break up soil and increase infiltration water storage. In this study, 2.2 km2 area in Warwickshire, England, planted with woodland every year from 2006 2012, was sampled using Mini Disk infiltrometer (MDI). Infiltration measurements were taken 10 200 cm away the trees, November 2019...

Linearized versions of the Nelson-Siegel (1987) and Svensson (1994) models for the cross-sectional estimation of spot yield curves from samples of coupon bonds are developed and analyzed. It is shown how these models can be made linear in the level, slope and curvature parameters and how prior information about these parameters can be incorporated in the estimation procedure. The performance of...

A methodology for elaborating multi-temporal Sentinel-1 and Landsat 8 satellite images for estimating topsoil Soil Moisture Content (SMC) to support hydrological simulation studies is proposed. After pre-processing the remote sensing data, backscattering coefficient, Normalized Difference Vegetation Index (NDVI), thermal infrared temperature and incidence angle parameters are assessed for their...

The U.S. Army Corps of Engineers’ Hydrologic Engineering Center’s River Analysis System (HEC-RAS) is a widely used software application for performing one-dimensional and two-dimensional steady and unsteady flow river hydraulics calculations, sediment transport-mobile bed modeling, and water quality analysis. User’s of HEC-RAS have often unique applications including the coupling with other sof...

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....

Abstract Hydrological modeling is important to provide relevant hydrologic information from limited data. In this study, Hydrologic Modeling System (HEC-HMS) was used simulate the rainfall–runoff relationship for Dabus subbasin of Blue Nile Basin. Daily precipitation and stream flow data 2002 2019 were as key input model, together with soil land use/land cover data, a digital elevation model st...
