On the informative value of the largest sample element of log-Gumbel distribution
(Versita, 2007-12)
Extremes of stream flow and precipitation are commonly modeled by heavytailed
distributions. While scrutinizing annual flow maxima or the peaks over
threshold, the largest sample elements are quite often suspected to be ...
Kinematic wave model of bed profiles in alluvial channels
(American Geophysical Union, 2006-06-21)
A mathematical model, based on the kinematic wave (KW) theory, is developed for describing the evolution and movement of bed profiles in alluvial channels. The model employs a functional relation between sediment transport ...
Kinematic wave model for transient bed profiles in alluvial channels under nonequilibrium conditions
(American Geophysical Union, 2007-12-27)
Transient bed profiles in alluvial channels are generally modeled using diffusion (or dynamic) waves and assuming equilibrium between detachment and deposition rates. Equilibrium sediment transport can be considerably ...
A fractional dispersion model for overland solute transport
(American Geophysical Union, 2006-03-18)
Using the kinematic-wave overland flow equation and a fractional dispersion-advection equation, a process-oriented, physically-based model is developed for overland solute transport. Two scenarios, one consisting of downslope ...
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 ...
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 ...
Longitudinal Dispersion Coeffiient in Straight Rivers
(2001-11)
An analytical method is developed to determine the longitudinal dispersion coefficient in Fischer’s triple integral expression for natural rivers. The method is based on the hydraulic geometry relationship for stable rivers ...
Derivation Of The SCS-CN Parameter S From Linearized Fokker-Planck Equation
(2003)
The potential maximum retention, S, of the Soil Conservation Service Curve Number (SCS-CN) method (SCS, 1956) was derived for a large set of published infiltration data ranging from Plainfield sand to Yololight clay using ...
Physics Of Flood Frequency Analysis. Part I. Linear Convective Diffusion Wave Model
(2002)
It is hypothesized that the impulse response of a linearized convective diffusion wave (CD) model is a probability distribution suitable for flood frequency analysis. This flood frequency model has two parameters, which ...
