Speeding Across Spain
Spain is extending its high-speed rail system�the Alta Velocidad Espa�ola (AVE)�to include a line running from Madrid to Lleida, with stops in Guadalajara and Zaragoza. The line will extend...
Stabilizing a Crater Rim
A geocell and geogrid reinforced soil slope concept was selected to stabilize approximately 120 m of eroding and unstable portions of the crater rim at the National Memorial Cemetery of...
The California Experience
With a terrain that ranges from the highest mountains to the lowest deserts, from salt marshes to beaches, from sierra to plateau, the natural environment that challenges the California...
Making Way for Water
The State Water Project Coastal Branch Aqueduct and Extensions brings 48,000 acre feet of water annually to 23 Southern California communities. built over five years, the project involved...
Paradise Crossed
Hawaii's Interstate H-3 project is the winner of the 1998 Outstanding Civil Engineering Achievement Award. The highway, built to alleviate commuter congestion and to link...
Bringing Low Flow to Eskimos
Engineers in Alaska initiated a program to bring potable water and wastewater service to a town of 500 Yup'ik Eskimos. This entailed building a 7.2 km boardwalk over permafrost...
Outside Plant
Outside Plant can be defined as equipment and facilities connecting a CO to other COs, and connecting a CO to subscribers. Depending on the distance and the terrain involved, the methods...
Runoff Computation Using Spatially Distributed Terrain Parameters
A spatially distributed unit hydrograph is developed based on linear system theory applied to subareas or cells within a watershed Each cell has a unique unit response function independent...
Water Balance of the Niger Basin
A map-based method is used to construct a monthly water balance model of the 2.3 million km Niger River basin in West Africa. The watersheds and stream network within the basin are derived...
Enabler Chassis Features and Mobiltiy Analysis
The Enabler is a proposed Lunar Base work vehicle. The unique construction of the Enabler's six-wheeled chassis provides unusual articulation for steering, balancing, and overcoming obstacles....
Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...
Combining a 2-D Flood Plain Model with GIS for Flood Delineation and Damage Assessment
This paper describes potential applications of Geographical Information System (GIS) for flood hazard delineation and damage assessment. The hydraulic model simulates both 1-D flood routing...
Detecting Dam Failures
Federal Energy Regulatory Commission guidelines say that unattended hydroelectric dams must be monitored against failure around the clock. Design and installation of failure monitoring...
Sampling Sediment on a Complex Site
The remedial design of a complex Superfund site hinged on a variety of sampling methods required by the site's diverse terrain. Cadmium, lead, cobalt and nickel are the culprits...
Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...
Convective Model Applications: Mountainous Terrain
