Circulation and Flushing in Casco Bay, Maine
A modified 3-D hydrodynamic numerical model MECCA (Model for Estuarine and Coastal Circulation Assessment; Hess, 1989) has been applied to Casco Bay, Maine, with a horizontal resolution...
Modeling Initial Mixing of Ocean Wastewater Discharges to Develop Toxic Effluent Limitations
The UM model, released by USEPA in 1992, was utilized to simulate the initial mixing of a discharge to the Atlantic Ocean near Ocean City, New Jersey. The study included field verification...
Computerized Building Settlement Analyses for a Contaminated Groundwater Remediation Project
The use of spreadsheets is becoming ever more popular in the practice of civil engineering. Engineers are able to use this tool to meet deadlines which were once insurmountable. This paper...
The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...
Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...
Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...
A Case History of Settlement of an Embankment on Lagoonal Deposits Influenced by Artesian Conditions
A geotechnical engineering investigation was performed for the Pearl Kai Center, a shopping center in the Pearl Harbor area of the island of Oahu, Hawaii. The proposed commercial development...
Performance of Oil Storage Tanks on Vibroflotation Improved Hydraulic Fill in the Port of Tampa, Florida
The paper describes a case history of design, construction and performance monitoring of two 80,000 barrel oil storage tank foundations 35 meters in diameter on a soft hydraulic fill soil...
Prediction of Low Level Vibration Induced Settlement
A prediction model of vibration induced settlement was developed for small to intermediate vibration levels (0.25-1.78 cm/s). Seven factors affecting vibration induced settlement such...
Settlement Predictions Using Piezocone
Detailed data on settlement predictions and measured values are given for two water tanks and an area of fill constructed on a thick soft clay stratum that showed decreasing preconsolidation...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
Performance of Three Large-Diameter Oil Tanks on Soft Clay
Preloading using a clay surcharge at the proposed locations of 3 large-diameter steel oil storage tanks founded on a 20-m thick stratum of soft Nile-delta silty clay produced about 1.5...
Settlement of Deep Compacted Fills in California
Measured settlement of deep compacted engineered fills from a single site were summarized and compared to data from other sites. The data indicate that the rate and magnitude of movement...
Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...
Collapse Mechanism of Compacted Clayey and Silty Sands
The mechanism of wetting-induced collapse (hydrocompression) and the influence of fines ratios on compacted sandy soils are investigated. Various ratios of clay and silt are mixed with...
Settlement of Building Foundations on Clay Soil Caused by Evapotranspiration
This paper reports on the results of a field investigation and settlement monitoring program which involves five buildings founded on shallow foundations in the sensitive clay deposits...
Prediction of Movement in Expansive Clays
The movement of expansive soils is usually due to a change of suction near the soil surface. The properties of the soil that govern the amount and rate of movement are the suction compression...
Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...
Reliability Analysis of Water Distribution Systems
The aging and deterioration of our water supply infrastructure have resulted in performance deficiencies. Limited budgets require that resources for maintenance and rehabilitation be allocated...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
