Geotechnical Aspects of Waterfront Parks: Case Histories
This paper presents several case histories of waterfront developments, and describes the general approach that the geotechnical consultant should take in the design of these projects....
Innovative Repairs to Steel Sheet Pile Structures
Several unique and many unusual repair techniques have been used to structurally rebuild steel sheet pile walls. An example of a unique repair to a cellular cofferdam utilizing a suspended...
Rehabilitation of Gravity Wharf by Underpinning
The Municipal Wharf at the Port of Providence, Rhode Island, is currently under rehabilitation to accommodate modern trends in marine cargo handling and shipping. The three-phased project...
Port of Kismayo (Somalia) Rehabilitation
Extensive deterioration of the 2070 ft long four-berth, marginal wharf at the Port of Kismayo necessitated a major rehabilitation to maintain operations. The selected scheme was a steel...
Tiebacks for Bulkheads
Tiebacks were once used primarily to support temporary structures such as supported excavations. However, the use of tiebacks has been gradually expanded to include the support of permanent...
Implications of Soluble Microbial Products (SMP) Formation on Biofilm Reactor Performance
The objective of this study is to evaluate the implications of SMP formation for biofilm treatment. To do so, the extended steady-state model was applied to predict effluent concentrations...
Field Study of Specialized Bacteria for Nitrification
A full scale field study using specialized bacteria was conducted to determine its effectiveness in achieving nitrification while quantifying dosage rates. A side-by-side comparison of...
Design Considerations and Experiences with VOC Treatment Technologies
This paper presents a review of design considerations and experiences with packed column aeration for removal of volatile organic chemicals (VOC) from groundwater at various locations...
Removal of Phenol from a Brine Aquifer: 2 Years of Operation
The article describes a pilot plant project to biologically treat groundwater polluted with phenols. The treatment scheme was based on laboratory tests, technical and economic analysis....
Unit Operations Approach in Exposure/Release Evaluation for New Chemicals
The unit operations approach may also be applied to the estimation of potential exposure and release of toxic materials from the manufacture and/or processing of new chemicals. By characterizing...
Large Scale ABF Mode Proves to be an Innovative Alternative for the City of Memphis
The article describes a modification carried out to overcome overloading of wastewater treatment plant at Memphis. The plant was originally constructed as a contact stabilization activated...
Biological Removal of Low Levels of Chlordane
This study investigated the removal of chlordane from a synthetic hazardous waste landfill leachate with chlordane as the only hazardous material. The chlordane concentrations investigated...
Mixing and Polymer Performance in Sludge Dewatering
A biofilm reactor, termed the support-aerated biofilm (SAB), was developed in which oxygen was supplied to the interior of the biofilm through a permeable membrane. The reactor was tested...
Leaching Characteristics of Metal Finishing Sludges
The purpose of this research was to study the feasibility of biodegrading phenolics to methane by thermophilic anaerobic treatment. The study was a feasibility level assessment which examined...
Saltwater Intrusion in a Highly Transmissive Unconfined Aquifer
Saltwater intrusion is particularly dynamic in coastal Dade County because of the high permeability of the Biscayne aquifer, because of the good interconnection between canals and the...
Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....
Agricultural Drainage Water Treatment?Are Toxic Elements Useful?
The problems pertaining to disposing of agricultural drainage water in the San Joaquin Valley are explained. Details are presented on a pilot plant which is pretreating the drainage water...
Stochastic Design of Wastewater Storage Ponds
The authors combine the principle of mass conservation with basic ideas from probability theory and then apply Monte Carlo simulation techniques to develop a family of design charts called...
