Abstract: The physical background and some mathematical aspects of advection‐dispersion models are reviewed. It is shown that flood and pollution routing can be accomplished by the same numerical scheme, derived from the discretization ...

Abstract: The tightening of dissolved oxygen (DO) standards in recent years suggests the employment of an accurate predictive method of the BOD‐DO conditions in streams. An advanced method should account for dispersion, which can ...

Abstract: The ability to accurately route flows through storm drain networks relies not only on the skill of the engineer, but also on the resources at his disposal. The purpose of this paper is to stress the advantage of using a ...

Abstract: A practical approach to modeling the hydraulic interaction of a stream and aquifer via streambed leakage is based on the established U.S. Geological Survey (USGS) model, MODFLOW. To represent flood-wave propagation and the ...

Abstract: Inclusion of longitudinal dispersion enhances realism in the assessment of transport in streams by accounting for contaminant mixing. Here we revisit the problem of estimating the longitudinal dispersion coefficient

Abstract: A method for the numerical simulation of longitudinal dispersion of pollutants in streams is developed and tested. It is based on the one‐dimensional, linear advection‐dispersion equation and utilizes the concept of numerical ...

Abstract: DEMOS is an interactive model for the analysis and design of dendritic sewer networks. It routes hydrographs and pollutographs through conduits and detention basins on the basis of the one‐dimensional advection‐diffusion ...
