Probabilistic Approach to Local Bridge Pier Scour
(1992)
A method is presented for evaluating the risk of failure of bridge structures due to pier scour during flood events. The method takes into account the hydrodynamics of the flow field in the vicinity of the pier. A newly ...
Application of Kinematic Wave Equations to Border Irrigation Design
(The British Society for Research in Agricultural Engineering, 1985)
Accuracy of the kinematic wave (KW) approximation was tested on 31 experimental irrigation borders by computing the KW number and its modified version. In a majority of cases. This approximation was found to be sufficiently ...
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 ...
SCS-CN Method. Part I: Derivation of SCS-CN-Based Models
(2002)
This part of the paper, in a sequence of two, provides an analytical treatment of the Soil Conservation Service Curve Number (SCS-CN) method including its derivation from a) early rainfall-runoff methods, such as the Mockus ...
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 ...
