Maximum Weighted Log-Likelihood Estimation for Parameterization Selection Uncertainty
Hydraulic conductivity identification remains a challenging inverse problem in groundwater modeling because of inherent non-uniqueness and lack of flexibility in parameterization methods....
Enhancing the Solution of Large Monitoring Network Design Problems Using a New Epsilon-Dominance Hierarchical Bayesian Optimization Algorithm
Designing long-term monitoring (LTM) networks for contaminated groundwater is a challenging problem that has long been recognized to suffer from the curse of dimensionality. LTM design...
Irrigation Hydrology: Crossing Scales
Hydrology is the science concerned with distribution, circulation, and properties of water of the earth and its atmosphere, across the full range of time and space scales. Subject matter...
Impact of Scaling Rule on Simulating the Transport of DNAPLs
Due to the pollutants from lots of industry sewage and organic solvents, they arelow solubility in water and hard to decompose in nature, didn.t treated adequately, itwill cause the ground...
Scaling the Monument
One of the three phases in the restoration of the Washington Monument was the design and construction of an aluminum scaffolding system with both functional and aesthetic purposes. The...
Fouling of Nanofiltration Membranes by Natural Organic Matter
Nanofiltration membranes (with pore sizes on the order of 10-9 m) have been shown in pilot plant studies to provide a very effective means of removing...
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
Pilot Test on Groundwater Organics Removal by Low-Pressure Membranes
A 1-year membrane pilot study has been performed to evaluate disinfection-byproduct (DBP) precursors and color removal by low-pressure membranes from groundwater with color values up to...
Scale Dependence of Effective Media Properties
For problems where media properties are measured at one scale and applied at another, scaling laws or models must be used in order to define effective properties at the scale of interest....
Energy Dissipation Characteristics of Rubber Cylinders
A simplified procedure for scaling the energy absorption characteristics of rubber cylinders during high speed impact is presented. Static and dynamic tests of scale model and full size...
Design Considerations for Large-Scale Filament-Wound Composite Structures
An experimental investigation was conducted to quantify scaling effects in filament-wound composite structures. These preliminary results support the notion that an increase in thickness...
Movable-Bed Model Study of Storm-Induced Beach Fill Erosion at Ocean City Maryland
Movable-bed physical model scaling guidance has recently been validated for the case of turbulent-dominated sediment transport, such as occurs in the surf zone. The tests successfully...
Hydrogen Sulfide in Hydropower Reservoirs
Hydrogen sulfide is toxic to aquatic life and corrosive to construction materials at concentrations that are considerably lower than detection limits of analytical procedures commonly...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
Fouling and Wood-Boring Communities Distribution on the Coast of Rio De Janeiro
The paper reports on a study of the dynamics of fouling communities and the distribution of wood-boring organisms along the coast of Rio de Janeiro, Brazil, which was motivated by the...
Application of Field Proven Fine Bubble Membrane Aeration Technology
Fine bubble membrane diffusers represent a significant technological advancement in diffused aeration technology by providing the consistently high transfer efficiencies of fine bubble...
Biofouling Control of Water Intake Structures
Biofouling of water intakes can affect condenser performance and availability. This paper discusses four biofouling control technologies: thermal backwash, antifouling coatings, chlorination,...
