An entropy-based morphological analysis of river basin networks
(American Geophysical Union, 1993-04)
Under the assumption that the only information available on a drainage basin is its mean elevation, the connection between entropy and potential energy is explored to analyze drainage basins morphological characteristics. ...
Granulometric characterization of sediments transported by surface runoff generated by moving storms
(Copernicus Publications on behalf of the European Geosciences Union and the American Geophysical Union, 2008-12-16)
Due to the combined effect of wind and rain, the importance of storm movement to surface flow has long been recognized, at scales ranging from headwater scales to large basins. This study presents the results of laboratory ...
Downstream hydraulic geometry relations: 2. Calibration and testing
(American Geophysical Union, 2003-12-04)
Using 456 data sets under bank-full conditions obtained from various sources, the geometric relations, derived in part 1 [ Singh et al., 2003 ], are calibrated and verified using the split sampling approach. The calibration ...
A distributed converging overland flow model: 1. Mathematical solutions
(American Geophysical Union, 1976-10)
In models for overland flow based on kinematic wave theory the friction parameter is assumed to be constant. This paper studies a converging geometry and allows continuous spatial variability in the parameter. Parameter ...
Downstream hydraulic geometry relations: 1. Theoretical development
(American Geophysical Union, 2003-12-04)
In this study, it is hypothesized that (1) the spatial variation of the stream power of a channel for a given discharge is accomplished by the spatial variation in channel form (flow depth and channel width) and hydraulic ...
Hybrid fuzzy and optimal modeling for water quality evaluation
(American Geological Union, 2007-05-08)
Water quality evaluation entails both randomness and fuzziness. Two hybrid models are developed, based on the principle of maximum entropy (POME) and engineering fuzzy set theory (EFST). Generalized weighted distances are ...
A distributed converging overland flow model: 3. Application to Natural Watersheds
(American Geophysical Union, 1976-10)
The proposed distributed converging overland flow model is utilized to predict surface runoff from three natural agricultural watersheds. The Lax-Wendroff scheme is used to obtain numerical solutions. For determination of ...
