Channel flow routing provides information on the movement of flood wave as it travels downstream. From the flood forecast viewpoint, it is desirable to have some knowledge about the expected arrival time of peak flow. However, many parameters involved in the flow routing model, in reality, can not be quantified with certainty. In this paper, a probabilistic analysis using the Mellin transform i...

Water engineering problems are typically nonlinear, multivariable, and multimodal optimization problems. Accurate water problem helps predict these systems’ performance. This paper proposes a novel algorithm named enhanced multioperator Runge–Kutta (EMRUN) to accurately solve different types of The EMRUN’s novelty is focused mainly on enhancing the exploration stage, utilizing search mechanism ...

land use change is one of the main factors in the process of changing the regime of flood in watersheds. taleghan watershed has been subjected to many land use changes over years, which probably effects on flood characteristics of taleghan river. in present study the effects of land use change on some parameters including peak flow, volume and flood base time, in part of taleghan basin, was inv...

The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects will occur. This study discusses development hydrological model with application Hydrologic Engineering Center (HEC-HMS) in Karangmumus watershed using data has been verified field divided into zones based on permeability testing laboratory. With hel...

The interaction between groundwater (GW) and surface water (SW) not only sustains runoff in dry seasons but also plays an important role river floods. Lateral inflow is the recharge of to during a flood; this part GW-SW exchange. Hydrological engineers proposed idea modelling flood routing using Muskingum-Cunge method, which exchange fully considered. This study proposes improved nonlinear mode...

Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...
