Predicting Overland Flow Response: Effects of Spatially-Varying Soil Properties
A physically-based model of Horton overland flow is applied to experimental data from a simulated rainfall event in eastern Washington. The model employs the Green-Ampt infiltration equation...

Computation of Unsaturated Soil Parameters Using Upward Infiltration Empirical Data
The relationship between soil moisture content and hydraulic conductivity with the soil tension be defined to simulate unsaturated flow in a porous media. Direct measurements of these...

A Mathematical Model of Erosion and Sedimentation of Hyperconcentrated Flow in Reservoirs
The motion of the flow with hyperconcentration has its unique law. In this paper, based on the analysis of the motion of the flow with hyperconcentration of sediment and the sediment transport...

A Hybrid Model for Sediment Concentration Profiles
The paper discusses the deficiency in the existing theories on suspended concentration profiles which is due to the variations of theories for modeling the velocity profiles. As can be...

Scour in Non-Cohesive Beds at Culvert Outlets
An empirical relationship was developed to estimate the depth of scour in non-cohesive material at culvert outlets. The scour depth is expressed as a function of mean particle size of...

Maximum Scour Below Dams Caused by Over-Fall Flow
The scour of sediment below a check dam caused by over-fall flow will lead to the destruction of dams. The formation of the scour hole below the dam will lead to shorten the seepage lines,...

An Investigation of Continuity Equation and Flood Routing
In this paper, a flood routing scheme, which gives consideration to the advantages of both the Muskingum method and the unit hydrograph method, is derived by using the continuity equation...

Kinematic Wave Based Hydrologic Models with Different Solution Methods
The hydrologic simulation models RUNOFF and HEC-1 are applied to a 3212-ha watershed in New Jersey, and performances of the two models in predicting historical stromwater hydrographs from...

Comparison of Correction Factor for Dispersion Coefficient Based on Entropy and Logarithmic Velocity Profiles
Recently, new velocity distribution equations have been developed by Chiu (1987, 1989) through the use of maximum entropy principle. A comparison will be made of the correction factor...

3-D Cavity Flow Analysis by a New Fractional Step Method Based on the Finite Element Method
This paper describes a new finite element scheme for solving the time-dependent incompressible viscous fluid flow expressed in terms of the Navier-Stokes equations. The main feature of...
