Engineering Aspects of Wetland Design
Successful wetland enhancement, restoration, or creation projects require integration of desired wetland functions, local hydrologic and soil conditions, and biological requirements into...
Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...
Fingerprint Identification of Groundwater Petroleum Contamination Using Synchronous Scanning Fluorescence
Synchronous scanning fluorescence spectroscopy, SSF, is a simple, cost effective method for the fingerprint analysis of many petroleum contaminates in groundwater and soil samples. The...
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...
Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...
Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...
Proposed Development of South Central Florida Hydrologic Ecosystem Model
The Corps of Engineers has been authorized to develop and operate a simulation model of the hydrologic ecosystem of central and south Florida. This ecosystem is fragile and complex, and...

Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...
Investigation of a Concrete Blistering Failure
During construction of a concrete pavement at a military airfield, numerous small blisters formed on the concrete surface behind the slipform paver and were filled by the contractor using...
Standard Methodologies for the Forensic Investigation of Pavements
The high costs of new construction have made the preservation and restoration of existing pavements an attractive alternative to replacement structures. Existing pavements that are to...
An Airfield Pavement Forensic Analysis: Cairo East Air Base
The US Army Engineer Waterways Experiment Station (WES) was requested by the Middle East/Africa Projects Office in April 1989 to provide technical assistance in analyzing an unstable asphalt...
Forensic Analysis of a Two-Component Joint Sealant Using FTIR-ATR
Fourier-Transform Infrared Spectroscopy using Attenuated Total Internal Reflectance (FTIR-ATR) was used to chemically identify joint sealants obtained from an airfield pavement joint which...
Procedures for Evaluating Aggregate Gradation Specifications
The construction and rehabilitation of transportation facilities annually consumes huge quantities of aggregates. And, the variability in supply and demand for these materials as well...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Forensic Analysis Techniques for Joint Sealants
Growing concerns involving the field performance of pavement joint sealant materials has illustrated the need for forensic capabilities in determining the cause of sealant failures. Methods...
Implementation of Material Requirements in Specifications
