Sediment Graphs Based on Entropy Theory
(2014-08-20)
Using the entropy theory, this paper derives an instantaneous unit sediment graph (IUSG or USG) to determine sediment discharge and the relation between sediment yield and runoff volume. The derivation of IUSG requires an ...
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 ...
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, ...
Bivariate Rainfall and Runoff Analysis Using Entropy and Copula Theories
(2012-09-24)
Multivariate hydrologic frequency analysis has been widely studied using: (1) commonly known joint distributions or copula functions with the assumption of univariate variables being independently identically distributed ...
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 ...
Water requirements and single and dual crop coefficients of sugarcane grown in a tropical region, Brazil
(2012)
A field experiment was conducted throughout 2009/2010 in a sugarcane field of a commercial distillery located on the coastal area of Paraiba state, Brazil. The objectives were to determine sugarcane water requirements and ...
