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 ...
Derivation of Rating Curves Using Entropy Theory
(American Society of Agricultural and Biological Engineers, 2010)
Using the entropy theory, this study derives the stage‐discharge relation, often called the rating curve, which is based on two simple constraints: (1) the total probability and (2) the mean logarithmic discharge. Parameters ...
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 ...
Derivation of Furrow Geometry Using Entropy Theory
(American Society of Agricultural and Biological Engineers, 2012)
The instantaneous unit hydrograph (IUH) is a commonly used method for computing surface runoff hydrographs from small watersheds. Assuming travel time as a random variable, a general equation for IUH is derived using the ...
Tsallis Entropy Theory for Derivation of Infiltration Equations
(American Society of Agricultural and Biological Engineers, 2010)
An entropy theory is formulated for deriving infiltration equations for potential rate (or capacity) of infiltration in unsaturated soils. The theory is comprised of five parts: (1) Tsallis entropy, (2) principle of maximum ...
An IUH Equation Based on Entropy Theory
(American Society of Agricultural and Biological Engineers, 2011)
The instantaneous unit hydrograph (IUH) is a commonly used method for computing surface runoff hydrographs from small watersheds. Assuming travel time as a random variable, a general equation for IUH is derived using the ...
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 ...
