Flow Resistance Interactions on Hillslopes With Heterogeneous Attributes: Effects on Runoff Hydrograph Characteristics

Sediment transport by runoff on debris-mantled dryland hillslopes

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

A Simple Model for Flow on Hillslopes

A simple hillslope hydrological model predicting water movement on sloping shallow soils is developed. Unlike existing hillslope models, the new model can be used to predict flow for long records of climatological data and it can be easily extended to include preferential flow. It compares favorably to other models with more restrictive input requirements. Its application is illustrated for exp...

Flood Hydrograph Simulation with Uncertainty in Rainfall - Runoff Parameters

Flood hydrograph simulation is affected by uncertainty in Rainfall – Runoff )RR( parameters. Uncertainty of RR parameters in Gharasoo catchment, part of the great Karkheh river basin, is evaluated by Monte–Carlo (MC) approach. A conceptual-distributed model, called ModClark, was used for basin simulation, in which the basin’s hydrograph was determined using the superposition of runoff generated...

Conceptualizing lateral preferential flow and flow networks and simulating the effects on gauged and ungauged hillslopes

[1] One of the greatest challenges in the field of hillslope hydrology is conceptualizing and parameterizing the effects of lateral preferential flow. Our current physically based and conceptual models often ignore such behavior. However, for addressing issues of land use change, water quality, and other predictions where flow amount and components of flow are imperative, dominant runoff proces...
