Improving overland flow routing by incorporating ancillary road data into Digital Elevation Models
Watershed Delineation Road Geographic Information System GIS Flow Direction Digital Elevation Model DEM Hydrological Modeling
2015/8/6
Roads, ditches, and culverts influence hydrological and geomorphological processes significantly. However, most hydrological models continue to rely solely on regional digital elevation models (DEMs) ...

Kinematic wave theory is utilized to investigate diverging overland flow which
does not appear to have been previously investigated in watershed hydrology.
This paper is the first in a sequel of two...
This paper presents kinematic solutions, both analytically and nomographically,
of surface water lag time for diverging overland flow. These solutions
can be utilized to estimate lag time from physi...
A desk-top method based on kinematic overland flow and Green-and-Ampt infiltration models is developed to determine the time of concentration of and the peak runoff rate from a converging basin. The g...
