Publisher Summary This chapter deals with the formulation of how to move how much water
into which neighboring cells in order to have a representation of reality that is suitable for a …

The accuracy of the predictions of distributed hydrological models must depend in part on
the proper specification of flow pathways. This paper examines some of the problems of …

This study explores various aspects of catchment hydrology based on a mechanistic
modeling of distributed watershed processes. A new physics‐based, distributed‐parameter …

We describe a new set of data structures and algorithms for dynamic terrain modeling using
a triangulated irregular network (TINs). The framework provides an efficient method for …

Flat areas are a critical issue for the characterization of drainage patterns using digital
elevation models (DEM). In this work, flat area removal and flow direction algorithms are …

Hydrologic processes are affected by the spatial variability of soils, topography, land use
and cover, climate, and human‐induced changes and management. Because contaminants …

The modelling of environmental processes based on catchment elevation surfaces is well-
established, but the use of TIN and grid surface models as three-dimensional …

This study attempts to develop a method for the simulation of surface flow paths on a digital
elevation model (DEM). The objective is to use a facet‐based algorithm to estimate the …

Computer-based terrain models have become increasingly popular as a tool for automating
much of the geometrical data acquisition necessary for hydrologic analyses. An algorithm is …

A hydrologic model for urban areas has been developed which incorporates distributed
parameter modelling concepts and functions in the context of a geographic information …
