Dry Weather Field Screening as an Indicator for Urban Drainage System Rehabilitation
In November 1990, EPA published final rules governing National Pollution Discharge Elimination System (NPDES) Permit Application Regulations for stormwater discharges. The rules affect...
Efficient Sizing of Storm Water Treatment Ponds
An anticipated result of the NPDES storm water program will be the proliferation of regional storm water ponds that capture and treat urban land surface runoff, thereby improving the quality...
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....
Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...
Use of Manned Submersibles to Investigate Slumps in Deep Water Gulf of Mexico
The Johnson-Sea-Link manned submersible was used to investigate surface slumps in the deep water Gulf of Mexico. High quality and specifically placed seafloor cores, video tapes, 35 mm...
The Thermal Regime Surrounding a Longitudinal Edge Drain
Newton Airfield in Jackman, Maine, was constructed in 1986 to perform as a drained pavement system. The drainage design consisted of a permeable base course with a longitudinal edge drain...
A Model to Predict the Production Rate of AMD
Results generated from a model to deterministically calculate the production rate of acid mine drainage compared to those generated by an empirical model are nearly identical. The model...
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
Computer-Assisted Geometric and Kinematic Analysis of Subsurface Faulting in the Vicinity of Yucca Mountain, Nevada, Using Balanced Geologic Cross Sections
Computer-assisted geological cross section balancing methods are used in the geometric and kinematic analysis of subsurface structures in the vicinity of Yucca Mountain, Nevada, including...
Pore-Water Extraction from Unsaturated Tuffs Using One-Dimensional Compression
To support the study of the unsaturated-zone hydrochemistry at Yucca Mountain, Nevada, a one-dimensional compression system was developed and tested to extract unaltered and uncontaminated...
Risk Assessments for the Design of Subsurface Openings
A probabilistic approach was introduced to assess the risk of structural instability due to rock joint systems in rock mass, where subsurface openings are excavated, such openings as shafts,...
Norfolk Uses a GIS to Satisfy its Stormwater Management Information Needs
The key component of stormwater management is to obtain a good understanding of the data describing the system so that regulatory, maintenance, and capital decisions concerning the system...
Integration of SCADA and GIS Technologies in Jefferson Parish, Louisiana
Due to its physiographic setting in the delta region of the Mississippi River, a majority of the inhabited lands in Jefferson Parish, Louisiana are below local mean sea level and much...
Automated Estimation of Hydrologic Parameters
An expert system was developed that automatically generates drainage area boundaries and times of concentration using digital elevation and stream data. Drainage areas and hydrographs...
Unique Water Quality Aspects of Lake Pontchartrain
Natural factors causing changes in Lake Pontchartrain, can be grouped into the following: subsidence and wetland loss due to the deterioration of the St. Bernard Delta, natural variations...
Forthcoming ASCE/WPCF Manual of Practice
The forthcoming ASCE/WPCF Manual of Practice for the Design and Construction of Urban Stormwater Management Systems includes, as Chapter 1, a derivation of the following text. This chapter...
Urban Storm Drainage Design Hydraulic Principles
Chapter 6 of the manual on Design and Construction of Urban Storm Water Management Systems discusses the hydraulic principles and equations under which drainage system structures must...
Drainage Design Criteria: Too Restricted? Too Broad? Too Outdated?
Should drainage design policies be more flexible, leaving the field more open to engineering judgment? Are some policies too loose or broad? Should design criteria more closely reflect...
Challenges in Planning and Design of Drainage Facilities for the Orange County Toll Roads
The Orange County Toll Roads project is a program which includes three modern, high-capacity, limited access highways; the Foothill, San Joaquin Hills and Eastern Transportation Corridors....
Mission Bay Park, San Diego Sewage Interceptor System
Mission Bay Park is a major aquatic facility located in, and operated by, the City of San Diego. In response to sewer related pollution problems, the City of San Diego has embarked on...
