A Raft System for Large River Hydraulic Measurements
Collection of hydraulic data in large rivers is a difficult, time consuming, and occasionally perilous task. High water velocities, considerable depths, and wide channels present obstacles...
Urban Runoff and the Environment
This paper discusses complex water quality problems, including management of urban runoff. Mathematical modelling is used to asses runoff quantity and quality. Environmental impact...
The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...
Simulation of ATIS Strategies to Mitigate Special Event Congestion
This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information:...
Cycletime Simulation of Shield-Tunneling Operation
Computer simulation...
Graphical Resource-Based Object-Oriented Simulation for Construction Process Planning
Simulation is a powerful tool for construction process design and optimization. The results of a simulation provide detailed process information, such as resource utilization and idleness,...
Simulation Architecture for Advanced Traffic Management Systems
Trends in Intelligent Highway-Vehicle Systems (IVHS), specifically Advanced Traffic Management System (ATMS) technologies are directed toward better integration between intersection controller...
Modeling the Traffic Flow Impacts of Rehabilitation Activity on Two-Lane Highways
Researchers at the Purdue University have been involved in developing techniques for predicting the operational impacts created by one-way traffic control. These techniques estimate average...
A Short-Term Demand Forecasting Model from Real-Time Traffic Data
Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions...
Landfill on Screen
Engineers for a $3.7 million regional landfill in Iowa turned to computer-aided design at every project step from conceptual design through operations monitoring following construction....
Free the Elwha|
The Elwha River flows northward from the middle of Washington's Olympic Peninsula to the Strait of Juan de Fuca. As a coastal river basin, it was once home to all five species of Pacific...
Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...
Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...
Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
Streambank Inventory and Protection Soldotna Reach, Kenai River, Alaska
This paper discusses bank conditions found along the Kenai River within the city of Soldotna in Alaska. River banks were inventoried in May 1990 by USDA Soil Conservation Service (SCS)...
Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...
Priority Problems of the Barataria-Terrebonne Estuarine Complex
The Barataria-Terrebonne Estuarine Complex encompasses an area of approximately 3600 square miles within the Mississippi deltaic plain, and consists of system of water bodies and wetlands...
Northwest Coastal Strategy
The activities of the Coastal AMerica Northwest Regional Implementation Team are discussed. The Coastal America northwest demonstration project, wetlands restoration in the Duwamish River...
Using GIS to Monitor Wetlands Loss/Gain
This paper represents the work being done at the National Wetlands Research Center (NWRC) for the U.S. Army Corps of Engineers (COE) to monitor wetland change in the Mississippi River...
Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...
