Abstract Event-based rainfall-runoff models are practical tools commonly used to predict catchments’ response a rainfall event. However, one of the main concerns is that characteristics rain events neglected in model development. This paper develops novel event-based equation incorporate into account. The performance new evaluated based on root mean square error, Nash–Sutcliffe efficiency coeff...

The hydrological models are important tools to evaluate the behavior of watersheds, helping in decision making. Thus, this study had objective evaluating performance Soil and Water Assessment Tool (SWAT) model flow simulation Ribeirão Taquaruçu Hydrographic Basin. Flow data from two fluviometric stations were used April 2013 August 2015. results sensitivity analysis indicated that most influent...

The ERA5 global reanalysis has been compared against a high-resolution regional (COSMO-REA6) by means of scale-separation diagnostics based on 2d Haar discrete wavelet transforms. presented method builds upon existing methods and enables the assessment bias, error skill for individual spatial scales, separately. A new score (evaluated random chance) Symmetric Bounded Efficiency are introduced. ...

Changing of precipitation regime and intensification extreme storms in semi-arid regions because climate change requires the use numerical models to forecast outlet hydrographs. In this paper, HEC-HMS software was applied using a loss method curve number CN estimate excess parametric unit hydrograph model compute transformation into direct runoff over watershed. The Muskingum-Cunge routing used...

With the acceleration of urbanization in a river basin, changes underlying surface structure basin are more and intense, which causes frequent floods. This article aims to analyze applicability HEC-HMS model flood simulation basins influence land use on catchment runoff. Pu River Basin is typical taken as research project. Based changes, soil types, long-term hydrological data Basin, constructe...

Rainfall–runoff responses were observed in a laboratory environment using rainfall simulator and 7.43 m2 green roof cassette equipped with weighing lysimeters. SWMM LID controls developed for various profile configurations based on the physical properties of composite materials. Unknown parameters affecting drainage layer adjusted calibration. The was modeled both as typical Green Roof control ...

In this study, we propose a hypothesis that an automatic calibration framework can address modeling uncertainties in the Storm Water Management Model (SWMM) due to structural defects result inability of model account for runoff generated on building walls from wind-driven rain. To test hypothesis, introduce rainfall error into indirectly consider effects inclined rain walls. We couple optimizat...

Abstract Analyses based on precipitation data may be limited by the quality of data, size available historical series and efficiency adopted methodologies; these factors are especially limiting when conducting analyses at daily scale. Thus, methodologies sought to overcome barriers. The objective this work is develop a hybrid model through maximum overlap discrete wavelet transform (MODWT) esti...

An assessment of hydropower potential at the watershed scale was conducted White Bandama Watershed (WBW) in Côte d'Ivoire (West Africa). The method used involves application a hydrological model [Soil and Water Assessment Tool (SWAT)] coupled with Quantum Geographic Information System (QGIS), denoted as QSWAT, to assess water resource availability streams determine sites for future development ...

Abstract This study presents a coupled invasive weed optimization-adaptive neuro fuzzy inference system method to simulate physical habitat in streams. We implement proposed Lar national park Iran as one of the habitats Brown trout southern Caspian Sea basin. Five indices consisting root mean square error (RMSE), absolute (MAE), reliability index, vulnerability index and Nash–Sutcliffe model ef...
