AN IMPLEMENTATION OF STAGE-FALL-DISCHARGE RELATIONSHIP ON DIGITAL COMPUTERS
IMPLEMENTATION STAGE-FALL-DISCHARGE RELATIONSHIP DIGITAL COMPUTERS
2009/10/30
The stage-discharge relation is defined by the complex interaction of channel
characteristics, including area, shape, slope, and roughness of the cross-section.
The combination of these effects has ...
Snow Surface Measurements from Digital Landsat MSS Data
Snow Surface Measurements Digital Landsat MSS Data
2009/10/28
The snow cover is an important parameter for water run-off prediction in high
mountain areas. At present its seasonal changes can be monitored regularly by
satellite. The paper presents a new method...

Digital Elevation Hydrological Modelling in a Small Catchment in South Australia
Digital Elevation Hydrological Modelling Small Catchment South Australia
2009/10/22
A rainfall runoff model based on a digital elevation model (DEM) was applied to a small catchment in Happy Valley, South Australia to predict catchment storm runoff. The DEM was used to partition the ...
THE EFFECT OF DIGITAL ELEVATION MODEL SCALE FACTOR ON SOIL EROSION STUDIES：CASE STUDY IN CAMERON HIGHLANDS, MALAYSIA
digital elevation model SOIL EROSION SCALE FACTOR
2009/10/12
The digital elevation model (DEM) is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. The DEM is a model of the elevation surface, which is...
Improved estimation of flood parameters by combining space based SAR data with very high resolution digital elevation data
synthetic aperture radar devastating catastrophes flood parameters
2009/7/22
Severe flood events turned out to be the most devastating catastrophes for Europe's population, economy and environment during the past decades. The total loss caused by the August 2002 flood is estim...
Uncertainties associated with digital elevation models for hydrologic applications：a review
Digital elevation models hydrologic applications surface flow
2009/5/12
Digital elevation models (DEMs) represent the topography that drives surface flow and are arguably one of the more important data sources for deriving variables used by numerous hydrologic models. A c...
Digital terrain analysis of the Haute-Mentue catchment an scale effect for hydrological modelling with TOPMODEL
digital elevation model topographic index
2009/3/24
It is widely recognised that topography plays an important role in the generation of runoff. The scale of a digital elevation model has been found to have some impacts on the results of hydrological m...
