Abstract: Overland flow erosion has a significant role in determining the drainage properties of a land surface. Most physically based models of soil erosion over hillslopes use a constant value of critical shear stress τ

Abstract: The method of characteristics is used to develop analytical expressions for the transient one-dimensional movement of fine particles at the local scale. These solutions are applicable when the porous medium is homogeneous ...

Abstract: Climatic variables that are used as inputs in hydrologic models often have large measurement uncertainties that are mostly ignored in hydrologic applications because of lack of appropriate tools. This study develops a set ...

Abstract: This study investigated the use of similarity profiles in space for analyzing surface-runoff hydrographs occurring at the outlet of small watersheds. The spatial behavior of the flow depth over each element (overland region ...

Abstract: We study the problem of field-scale infiltration over soils where spatial variability of saturated hydraulic conductivity is represented by a homogeneous correlated lognormal random field. The Green-Ampt equation was used ...

Abstract: The stochastic-convective model of solute transport was analyzed using interval arithmetic. An interval distribution function was developed to facilitate the identification of appropriate intervals to be used in the proposed ...

Abstract: Groundwater, one of the world’s most important natural resources, is under constant threat of exploitation with increasing population and economic development. Proper understanding and modeling of subsurface water movement ...

Abstract: Groundwater quality has been a long-standing concern to water engineers and managers. Numerous studies have examined the causes of contamination, and designs for remediation systems have been developed for contamination ...
