ANN and Fuzzy Logic Models for Simulating Event-Based Rainfall-Runoff
(2006-12-01)
This study presents the development of artificial neural network _ANN_ and fuzzy logic _FL_ models for predicting event-based rainfall runoff and tests these models against the kinematic wave approximation _KWA_. A three-layer ...
Analysis of Gradual Earth-Dam Failure
(1988-01-01)
Analytical models are developed for the simulation of earth-dam breach erosion. Using a reservoir water-mass depletion equation, broad-crested weir hydraulics and a breach-erosion relation, solutions ae derived for ...
Analysis of Nonlinear Muskingum Flood Routing
(1987-01-01)
The three-parameter nonlinear Muskingum method for flood routing is analyzed. Analytical solutions for simplifying cases and approximate integral solutions for general cases are derived. Its accuracy depends mainly on the ...
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, ...
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 ...
