Computer Simulation Modeling of Ebb-Tidal Deltas
An ebb-tidal delta simulation model has been developed incorporating gross features of delta and channel morphologies which can be measured from vertical aerial photographs. Delta and...
Satellite Imagery Refines PMF Determination
This paper focuses on electromagnetic energy sensors, and describes how they are being used to determine the Probable Maximum Flood (PMF) for a drainage basin in Michigan. Remote sensing...
Use of Remote Sensing and G.I.S. in the Economic Analysis of Flood Damage Reduction?Three Recent Case Histories
Three recent studies of the Trinity River in the nine-city Dallas-Fort Worth metroplex have been based on a regional geographic information system (G.I.S.), using digitized satellite imagery...
Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...
Evaporation and Snowmelt Estimates from Satellite Data
Satellite imagery has been used to estimate saltwater evaporation and snowmelt runoff. Water surface temperatures can be obtained from satellite thermal infrared data. Saltwater evaporation...
Remote Sensing of Rainfall with NEXRAD
In utilizing the Next Generation Weather Radar (NEXRAD) for remote sensing of rainfall, three stages of precipitation processing have been developed by the National Weather Service's...
Beach Evolution in Sulphur Island
Seasonal variation of shore area of Sulphur Island is studied by analyzing aerial photographs of the island taken seasonally for the past two years. Analysis reveals that shore area in...
Building on the Coastal Barriers Resource Act
In 1982, the Coastal Barrier Resources Act (CBRA) was enacted to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish and wildlife and other natural...
Pinpointing Nonpoint Pollution
The Tennessee Valley Authority is using aerial photography to locate nonpoint sources of water pollution. These cause most of the water quality problems in the region. Failing septic tanks...
An Overview of the Ease/Access Space Construction Demonstration
With the successful completion of the EASE/ACCESS demonstration, NASA took a significant step toward understanding construction in space. These experiments were performed on November 29...
National Wetlands Inventory Mapping for San Francisco Bay/Delta Area, California
The U. S. Fish and Wildlife Service's National Wetlands Inventory Project (NWI) completed wetland mapping in 1982-83 for the San Francisco Bay/Delta area of California using mid-1970's...
REMOTS?: Reconnaissance of Benthic Environments
REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling...
Remote Sensing of Estuaries and Tide-Dominated Coastal Processes
The recent appearance of low-cost microcomputers with user-friendly software for analyzing satellite imagery is including more estuarine investigators to use satellite data. High resolution...
The U.S. Geological Survey's National Real-Time Hydrologic Information System Using Goes Satellite Technology
The U. S. Geological Survey maintains the basic hydrologic data collection system for the United States. The Survey is upgrading the collection system with electronic communications technologies...
Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....
Satellite Remote Sensing for Regional Crop Inventories
LANDSAT 4 and 5 Satellite spectral images of the Columbia Basin were obtained during the 1984, 1985 and 1986 growing seasons by Cropix, Inc. of Hermiston, Oregon. A field classification...
Engineers in Court
Engineers who like debating often serve as expert witnesses. Though many avoid forensic work because they find lawyers intimidating, some like the challenge of explaining engineering principles...
Photogrammetric Analysis Using a Personal Computer
In many cases, photographs of the accident scene taken soon after the event contain visible evidence of road marks and/or debris. By the time the case reaches the accident investigator/reconstructionist,...
Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...
Turnaround in Houston
Simply implementing the suggestions of the workers building a 14-story garage in Houston, turned a disaster in the making into a project ahead of schedule and under budget. The work force...
