Scarlatos, Panagiotis D.; Singh, Vijay P. (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 ...

Scarlatos, Panagiotis D.; Singh, Vijay P. (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 ...

Genuchten, M. Th. van; Jain, Sharad K.; Singh, Vijay P. (2004-09-05)Many studies of water flow and solute transport in the vadose zone require estimates of the unsaturated soil hydraulic properties, including the soil water retention curve (WRC) describing the relationship between soil ...

Singh, Vijay P.; Tayfur, Gokmen (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 ...

Ram, Rama S.; Singh, Vijay P. (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 ...

Kwak, Jaewon; Kim, Soojun; Kim, Gilho; Singh, Vijay P.; Park, Jungsool; Kim, Hung Soo (2016-03-30)Long-term streamflow data are vital for analysis of hydrological droughts. Using an artificial neural network (ANN) model and nine tree-ring indices, this study reconstructed the annual streamflow of the Sacramento River ...

Li, Chao; Singh, Vijay P.; Mishra, Ashok K. (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 ...

Zhang, Lan; Singh, Vijay P. (Entropy (Basel, Switzerland), 2012)
-
Singh, Vijay P.; Zhang, Lan (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 ...

Singh, Vijay P.; Swiatek, Dorota; Tayfur, Gokmen; Wita, Andrew (2005-06-01)A finite element method (FEM) and an artificial neural network (ANN) model were developed to simulate flow through Jeziorsko earthfill dam in Poland. The developed FEM is capable of simulating two-dimensional unsteady and ...

Pruski, Fernando Falco; Rodriguez, Renata Del Giudice; Singh, Vijay P. (International Journal of Engineering Research and Technology, 2016-03-03)Water scarcity in semi-arid regions compromises the quality of life, principally human health, in these regions. The use of cisterns with adequate dimensions, that ensure the minimum of water required to meet human needs, ...

Khedun, C. Prakash; Mishra, Ashok K.; Singh, Vijay P.; Giardino, John R. (2014-01-14)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 ...
