Selection of Parameter-Estimation Method for LP3 Distribution
Publisher: American Society of Civil Engineers
Abstract: The quantile prediction accuracy of the log-Pearson type III (LP3) distribution depends largely on the accuracy of the parameter-estimation method used. The performance of a parameter-estimation method, on the other hand, ...
Regional Frequency Analysis of Extreme Precipitation in Louisiana
Publisher: American Society of Civil Engineers
Abstract: A regional frequency analysis procedure is outlined and applied to precipitation data in Louisiana. A total of 92 rain gauges were used to generate 25 synthesized stations with long periods of record. Annual maximum series ...
Modeling 3D Ground‐Water Flow by Modified Finite‐Element Method
Publisher: American Society of Civil Engineers
Abstract: In this study, a number of theoretical improvements were made to the finite‐element formulation for modeling three‐dimensional steady and unsteady ground‐water flow. First, the Galerkin method was combined with the collocation ...
Improved Finite-Element Method for Solute Transport
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Development of 24‐Hour Rainfall Frequency Maps for Louisiana
Publisher: American Society of Civil Engineers
Abstract: Maximum annual 24‐hour rainfall maps for return periods of 2, 5, 10, 25, 50, and 100 years were developed by using hourly precipitation data. Data from 92 rain gauges for the period of 1948 to 1987 were compiled and combined ...
1‐D, 2‐D, and 3‐D Infiltration for Irrigation
Publisher: American Society of Civil Engineers
Abstract: Models for one‐, two‐, and three‐dimensional infiltration for irrigation are derived using an energy equation and Darcy's law. The models were verified with Fok and Chiang's (4) experimental data. A good agreement is found ...
Discussion and Closure: Selection of Parameter-Estimation Method for LP3 Distribution

Cloud Cavitating Flow Over a Submerged Axisymmetric Projectile and Comparison Between Two Dimensional RANS and Three Dimensional Large Eddy Simulation Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the cloud cavitation around slender axisymmetric projectiles, a twodimensional (2D) numerical method was based on the mixture approach with Singhal cavitation model and modified renormalizationgroup (RNG) k–خµ ...
Thermal Conductivity Enhancement of Ethylene Glycol Based Suspensions in the Presence of Silver Nanoparticles of Various Shapes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this technical brief, the effect of adding silver (Ag) nanoparticles of various shapes on the thermal conductivity enhancement of ethylene glycol (EG)based suspensions was investigated experimentally. These included Ag ...
