Analysis of Gradual Earth-Dam Failure
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 ...
A Kinematic Model for Surface Irrigation
(American Geophysical Union, 1978-04)
A kinematic wave model is developed to study surface irrigation. Depending on the variability of infiltration and the kinematic wave friction parameter, three cases are distinguished. Explicit analytical solutions are ...
Evaluation of Models of Border Irrigation Recession
(The British Society for Research in Agricultural Engineering, 1982)
Recession characteristics play an important role in the design of border irrigation systems. This is particularly true of those borders which have closed downstream ends where surface storage is large even after the cessation ...
Probabilistic Approach to Local Bridge Pier Scour
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 ...
Improved Finite-Element Method for Solute Transport
Five major modifications to the Galerkin finite-element formulation for solute transport were made in this study: (1) A mixed formulation for the time-derivative term of the governing equation was developed by combining ...
Solution of Three-Constraint Entropy-Based Velocity Distribution
A two-dimensional velocity profile based upon the principle of maximum entropy (POME) for wide open channel flows is presented. The derivation is based on the conservation of mass and momentum. The resulting profile involves ...
Learning disabilities in Costa Rica: Challenges for "an army of teachers."
(Journal of Learning Disabilities, 1997)
Optimal Symbol-by-Symbol Detection for Duobinary Signaling
An optimal symbol-by-symbol detection scheme for duobinary signaling (Class I PRS) which exploits the inherent correlation properties of partial response signaling (PRS) is postulated. Analytical results indicate a maximum ...
Evidence for a Surface-Phonon Contribution to Thin-Film Superconductivity - Depression of Tc by Noble-Gas Overlayers
(American Physical Society, 1973)
Faceting via correlated disorder of a stochastically growing interface or domain boundary
(American Physical Society, 1998)
We consider a stochastically growing or evaporating interface in the presence of disorder which is correlated in the direction normal to the interface. The growth or evaporation rate at randomly distributed disorder points ...
