Utilization of Weather Radar for Hydrologic Forecasting
New technologies to collect, analyze, store, retrieve and display hydrologic data offer significant improvements to conventional methodologies used for predicting hydrologic events. Computer...

Remote Sensing and the Coastal Management in Brazil
This paper intends to demonstrate the possibility of employing remote sensing techniques in the Brazilian Coastal Management Program (Programa Brasileiro de Gerenciamento Costeiro). It...

Detection of 2-D Nearshore Wave Patterns Using Linear Prediction and SAR Data
Extraction of wave parameters such as wavelength and direction on radar images is normaly done using fast Fourier transforms (FFT) on typical image size of 256 × 256 which may not be appropriate...

HF Radar Ocean Surface Mapping in Monterey Bay as a Prototype for California Coastal Environmental Monitoring and Governance
A network of coastal HF radars is being established to provide real-time coverage of ocean surface currents, onshore waves, and ultimately wind fields over Monterey Bay. Data products...

Gas Transfer Velocities and Radar Backscatter from the Water Surface
Gas transfer velocities of sulfur hexafluoride, methane, and nitrous oxide were determined in two different wind-wave tanks and related to friction velocity and radar backscatter from...

Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...

Computer-Aided Structural Design of a Lunar Radio Telescope

Two-Dimensional Modeling of Overland Flow
Two-dimensional distributed finite element (F-E) and finite difference (F-D) models are developed to simulate storm events on arid watersheds. The F-E model uses the kinematic wave approximation,...

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...

A Multi-Level Contour Method for Tracking and Forecasting Rain Fields of Severe Storms by Weather Radars
A new automated method is developed in order to track and predict in short-term (15 min-1 hr lead times) the evolution of rain fields in time and space, as observed by weather radars....

Results from Three Rain/Snow Enhancement Cloud Seeding Programs in the Southern Sierra Range of California

Analysis on SLAR Images of Internal Waves

Radar Rainfall Measurements and Runoff Forecasting
Rainfall varies in intensity and depth over time and space. Weather radar systems can provide estimates of rainfall at points in space with nearly continuous coverage with respect to time....

New Clues to PMP
Great changes have occurred in meterology in the last two decades. Formerly, weather data were available for forecasting and climatological analyses only at points - at weather stations....

From Guesswork to Guarantee?
Maser describes a project to determine the effectiveness of radar and infrared thermography in detecting deterioration of asphalt overlaid bridge decks. The project, sponsored by the New...

Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...

A Regional Program on Coastal Monitoring and Management of Mangrove in Brazil
The results presented in this paper correspond to a synthesis of the evaluation of mangrove in the Brazilian coastal zone, based on calculations over radar imagery generated by RADAMBRASIL...

Measurements of Near-Survface Current in Inlets and Bays with Synthetic Aperture Radar
Synthetic Aperture Radar, SAR, provides images of land and ocean surfaces irrespective of solar illumination, and practically under all weather conditions. Developed originally for land...

The Estimation of Rainfall for Flood Forecasting Using Radar and Rain Gage Data
The use of radar-rainfall data in combination with rain gage measurements may improve rainfall estimates over those based on either form of measurement alone. A set of rainfall analysis...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
