An atlas of 26 maps (including index) is described showing existing tidal marshlands of the San Francisco Bay estuarine complex. This work is based upon a prior delineation and acreage...

Historical Atlas of Tidal Creeks, San Francisco Bay, California
Historic widths and depths of 69 major tidal creeks in San Francisco Bay were studied from maps dated from 1852 to the 1980's. Survey maps by the U.S. Coast Survey (and successors, U.S....

Challenges Associated with Metriciation of the Nautical Chart
Under the Metric conversion Act of 1975, Omnibus Trade and Competitiveness Act of 1988, and Executive Order 12770 of 1991 all federal agencies are required to convert to the international...

An Overview of Chemical Contaminants Throughout the Coastal and Estuarine United States
Informed decisions on the use and management of the nation's coastal resources require convenient access to current and reliable information. In 1984, the National Oceanic and Atmospheric...

Calculating Erosion Rates: Using Long-Term Data to Increase Data Confidence
Computer cartographic techniques were used to produce historical shoreline change maps for two study areas: (1) an eight kilometer section of Calvert County, Maryland; and (2) an eight...

Shoreline Erosional/Depositional Patterns in Oman
This paper presents a brief synopsis of the physical setting and geomorphology of the Oman coast, emphasizing the areas with the most dramatic erosional/depositional eyeless. Eighty-three...

A Man-Machine Partnership for Map Production: An Application of Image Classification and Auto-Vectorization in Charting Coastlines
The semi-automatic production of coastal area maps through computer processed digital images is described. Two sources of digital imagery were addressed: satellite and aircraft mounted...

Slides and Slumps on the Coastal Zone Between San Miguel and El Descanso, Baja California, Mexico
The coastline between Tijuana and Ensenada is being subject to intensive development, mainly as resort property, and because of the roughness of the adjacent areas inland, the coastal...

The North Black Sea and the Sea of Azov Coasts Under a Possible Greenhouse-Induced Global Sea-Level Rise
The first attempt is presented to compile a map of coastal evolution of the Black Sea and the Sea of Azov under the possible accelerated greenhouse-induced sea-level rise by 1m (medium...

Sandy Accumultive Forms Within the Black Sea Coastal Zone
Most of the sandy accumulative forms of the Black Sea are within Ukraine territory. There are various types of these forms differing in morphology, dynamics, source of material, interaction...

Designing the Framework for Coastal Mapping and Database Building in Support of a Coastal Zone Management Program: Nova Scotia, Canada
The Province of Nova Scotia has undertaken a program to manage its coastal zone. In support of this program it was recognized early in the process that comprehensive sets of data and information...

Comparative Accuracies of Technologies for Vehicle Location and Navigation
A variety of vehicle location and tracking technologies are under consideration for such IVHS applications as Automatic Vehicle Location (AVL), Computer Aided Dispatch (CAD), and vehicle...

Digital Mapping for Road Navigation in Japan
In Japan, more than 300,000 vehicles are presently equipped with car navigation systems. Development of these systems had been greatly aided by the completion of a standardized digital...

Monongahela River Mapping & Flood Hazard Study
The study described here represents a unique collaboration and cost-sharing effort between two Federal agencies: the U.S. Army Corps of Engineers (USACE) and the Federal Emergency Management...

Mean Areal Precipitation Estimation Using Radar
The accuracy of mean areal total storm precipitation (MAP) over small urban basins (30-100 km2) in the Denver, CO metro region was examined using...

The Utah Climate Center Weather Data Network
The Utah Climate Center weather data network includes 52 sophisticated, automated weather stations. Weather parameters are monitored in real-time and hourly summarized data are gathered,...

Advanced HEC-2 Modeling on Forester Creek
The goal of this paper is to share information regarding advanced modelling techniques used to solve complex hydraulic flow issues using the HEC-2 Computer Model (1990). There are several...

Hydraulic Modeling and Mapping of Mud and Debris Flows
The prediction of hyperconcentrated sediment flows on alluvial fans was advanced through the development of a two-dimensional, finite difference flood routing model FLO-2D. The model simulates...

Mapping Debris-Flow Hazard in Honolulu Using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of...
