Entropy approach for 2D velocity distribution in open-channel flow
(2011-11-21)
In this paper, considering time-averaged velocity as a random variable, two-dimensional (2D) velocity distributions in open-channel flow have been derived based on the Shannon entropy concept and the principle of maximum ...
Integrating Entropy and Copula Theories for Hydrologic Modeling and Analysis
(2015-04-15)
Entropy is a measure of uncertainty and has been commonly used for various applications, including probability inferences in hydrology. Copula has been widely used for constructing joint distributions to model the dependence ...
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, ...
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, ...
Tsallis Entropy-Based Flow Duration Curve
(American Society of Agricultural and Biological Engineers, 2014)
The flow duration curve (FDC) is employed for addressing a multitude of problems in water resources engineering, such as prediction of the distribution of future flows, forecasting of future recurrence frequencies, comparison ...
Entropy theory for derivation of infiltration equations
(American Geophysical Union, 2010)
An entropy theory is formulated for modeling the potential rate of infiltration in
unsaturated soils. The theory is composed of six parts: (1) Shannon entropy, (2) principle
of maximum entropy (POME), (3) specification ...
Modeling multisite streamflow dependence with maximum entropy copula
(American Geophysical Union, 2013)
Synthetic streamflows at different sites in a river basin are needed for planning, operation, and management of water resources projects. Modeling the temporal and spatial dependence structure of monthly streamflow at ...
