Singh, Vijay P., Auteur ; Jain, S. K., Auteur ; Van Genuchten, M. Th. |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 suction and water content.[...]

Mritunjay Kumar Singh, Auteur ; Premlata Singh, Auteur ; Singh, Vijay P., Auteur |Using the Hankel Transform Technique, an analytical solution is derived for two-dimensional solute transport in a homogeneous isotropic aquifer. The aquifer is subjected to time-dependent point source contamination. The solution is derived under[...]

Mishra, Surendra Kumar, Auteur ; Singh, Vijay P., Auteur |The Soil Conservation Service-curve number (SCS-CN) method is analytically derived and its basis in the Mockus method analyzed. A Modification and general form of the SCS-CN method are proposed. Using data from five watersheds, the existing SCS-[...]

Singh, Vijay P., Auteur ; Zhang, L., Auteur |Using the copula method, bivariate distributions of flood volume, and duration were derived. A major advantage of this method is that marginal distributions of individual variabls (i.e., flood peak, volume, and duration) can be of any form and t[...]

Adrian, Donald Dean, Auteur ; Singh, Vijay P., Auteur ; Deng, Zhi-Qiang, Auteur |A Multitude of natural processes occuring in environmental and water resources are diffusive processes, and their observations exhibit a natural lower bound of zero and pratically no upper bound. Such processes can be modeled using a dye diffusi[...]

Jain, M. K., Auteur ; Mishra, Surendra Kumar, Auteur ; Babu, P. Suresh ; Venugopal, K. ; Singh, Vijay P. |Incorporating the storm duration and a nonlinear relation for initial abstraction (Ia), this paper presents an enhanced version of the Soil Conservation Service curve number-based Mishra—Singh model. The proposed version is compared with existin[...]

Singh, Vijay P., Auteur ; Deng, Zhi-Qiang, Auteur |An Entropy based method is developed for estimating parameters of the four parameter kappa distribution. Using sets of data on annual maximum rainfall and on annual peak flow discharge, the entropy based method is evaluated and compared with the[...]

Tsai, Ching-Nien, Auteur ; Singh, Vijay P. ; Adrian, Donald Dean, Auteur |A Probability distribution is developed to describe data collected from processes that are diffusion driven, in addition to data sets in which the range of the random variable has a fixed lower bound, a fixed upper bound, or both. Chemical equil[...]

Liu, Q. Q., Auteur ; Singh, Vijay P., Auteur ; Teng, Michelle H., Éditeur scientifique |Using a laser-Doppler split-phase measuring technique, the rates of fluctuation in horizontal and vertical directions of pipe flow containing solid particles were observed. Employing these observations the effect of particles on flow turbulence[...]
