A study carried out in the Oldman River watershed in southern Alberta, Canada, to delineate
potential surface water pollution sources revealed that the use of conventional raster-based …

Roads, ditches, and culverts influence hydrological and geomorphological processes
significantly. However, most hydrological models continue to rely solely on regional digital …

The requirement to digitally delineate accurate watershed boundaries is a routine task
necessary in numerous natural science disciplines. The base topographic data necessary …

This dissertation examines the variations in the results of a physically-based kinematic
routing rainfall-runoff model (KINEROS2) in response to variations in the geometric model …

Urban development significantly alters the landscape by introducing widespread impervious
surfaces, which quickly convey surface run‐off to streams via stormwater sewer networks …

High‐resolution digital elevation data from two small catchments in the western United
States are used to examine the effect of digital elevation model (DEM) grid size on the …

Building channel networks in flat regions of digital elevation models (DEMs) is important for
watershed delineation and hydrological modeling, particularly for areas with gently-sloped …

Topography plays an important role in the distribution and flux of water and energy within
natural landscapes. The automated extraction of topographic parameters from DEMs is …

Abstract Digital Elevation Models are being employed with increased frequency in the
pursuit of watershed-based approaches for water resources studies and assessments …

Drainage direction assignment over flat surfaces in raster Digital Elevation Models (DEM)
