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 ...
Nappe Flow Surges down a Rough-Stepped Sloping Channel
(2017-07-22)
Nappe flow applies to small discharges, and investigation of nappe flow surges helps to understand the mechanism of water flow in stepped open channels. The objective of this paper is to investigate the nappe flow surge ...
A copula-based precipitation forecasting model: Investigating the interdecadal modulation of ENSO’s impacts on monthly precipitation
(American Geophysical Union, 2014-01)
The influence of two large-scale circulation patterns (the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO)), and the effect of the interdecadal modulation of ENSO on precipitation in the state ...
A bivariate mixed distribution with a heavy-tailed component and its application to single-site daily rainfall simulation
(American Geophysical Union, 2013-02)
This paper presents an improved bivariate mixed distribution, which is capable of modeling the dependence of daily rainfall from two distinct sources (e.g., rainfall from two stations, two consecutive days, or two instruments ...
Probability distribution functions for unit hydrographs with optimization using genetic algorithm
(2015)
A unit hydrograph (UH) of a watershed may be viewed as the unit pulse response function of a linear
system. In recent years, the use of probability distribution functions (pdfs) for determining a UH has received much ...
