for non-darcy flow in submerged porous media a one- dimensional mathematical model has been developed. rockfill detention dams are one of these porous media that comprised of relatively homogenous coarse rockfill which can be used to reduce flood discharge and hydrograph peak. in this research the focus was on the rockfill detention dams in submerged condition. the existence of overtopping rock...

This paper describes a one-dimensional finite element code for debris flows developed to model the flow within a steep channel and the stopping conditions on the fan. The code allows the systematic comparison of a wide variety of previously proposed one-phase flow resistance laws using the same finite element solution method. The onedimensional depth-averaged equations of motion and the numeric...

Knowledge of design peak flow is crucial in various applications related to hydrology, hydraulics and water resources management. However, obtaining challenging especially ungauged basins lacking discharge observations, a circumstance that does not allow the calibration advanced hydrological models. Recently, new method called EBA4SUB (Event-Based Approach for Small Ungauged Basins) was introdu...

The Sor and Gebba watershed has undergone several natural anthropogenic changes, as evidenced by the physical alterations artificial mismanagement of water resources in watershed. These situations alter underground storage aquifer contribution to streams. Thus, understanding baseflow enables us identify groundwater system potential dynamicity. main objective this research is estimate using hydr...

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...

The physically-based distributed hydrological models play an important role in watershed hydrology. Physical simulation of flow routing depends largely on the field distribution of flow velocity.Terrain analysis studies have previously focused more on the delineation of geomorphologic structures rather than the description of hydraulic factors. As affected by multiple uncertain factors includin...

This paper presents a comparative analysis of two hydrological models in the Storm Water Management Model (SWMM) software, namely, non-linear reservoir (N-LR) and unit hydrograph (UH), on urban catchment Cascina Scala, Pavia Italy. The were applied for simulation rainfall-runoff transformation 42 sub-catchments while flow routing underground channels was simulated by means De Saint-Venant equat...
