Entropy theory-based criterion for hydrometric network evaluation and design: Maximum information minimum redundancy
(American Geophysical Union, 2012)
Hydrometric information constitutes the fundamental input for planning, design, operation, and management of water resources systems. How to optimally site monitoring gauges such that they are effective and efficient in ...
Monthly river flow simulation with a joint conditional density estimation network
(American Geophysical Union, 2013)
River flow synthesizing and downscaling are required for the analysis of risks associated with water resources management plans and for regional impact studies of climate change. This paper presents a probabilistic model ...
Entropy theory for movement of moisture in soils
(American Geophysical Union, 2010)
An entropy theory is formulated for one‐dimensional movement of moisture in unsaturated soils in the vertically downward direction. The theory is composed of five parts: (1) Tsallis entropy, (2) principle of maximum entropy, ...
Single-site monthly streamflow simulation using entropy theory
(American Geophysical Union, 2011)
Using entropy theory, a new method for single-site monthly streamflow simulation is developed, which is capable of preserving mean, standard deviation, skewness, and lag-one correlation. The method entails deriving joint ...
Entropy-copula method for single-site monthly streamflow simulation
(American Geophysical Union, 2012)
An entropy-copula method is proposed for single-site monthly streamflow simulation. In this method, the joint distribution of adjacent monthly streamflows is constructed using the copula method, whereas the marginal ...
Case Study: Finite Element Method and Artificial Neural Network Models for Flow through Jeziorsko Earthfill Dam in Poland
(2005-06-01)
A finite element method (FEM) and an artificial neural network (ANN) model were developed to simulate flow through
Jeziorsko earthfill dam in Poland. The developed FEM is capable of simulating two-dimensional unsteady and ...
ANN and Fuzzy Logic Models for Simulating Event-Based Rainfall-Runoff
(2006-12-01)
This study presents the development of artificial neural network _ANN_ and fuzzy logic _FL_ models for predicting event-based rainfall runoff and tests these models against the kinematic wave approximation _KWA_. A three-layer ...
Analysis of Gradual Earth-Dam Failure
(1988-01-01)
Analytical models are developed for the simulation of earth-dam breach erosion. Using a reservoir water-mass depletion equation, broad-crested weir hydraulics and a breach-erosion relation, solutions ae derived for ...
Analysis of Nonlinear Muskingum Flood Routing
(1987-01-01)
The three-parameter nonlinear Muskingum method for flood routing is analyzed. Analytical solutions for simplifying cases and approximate integral solutions for general cases are derived. Its accuracy depends mainly on the ...
Derivation of 2D Power-Law Velocity Distribution Using Entropy Theory
(2013-04-08)
The one-dimensional (1D) power law velocity distribution, commonly used for computing velocities in open channel flow, has been derived empirically. However, a multitude of problems, such as scour around bridge piers, ...
