Available in PDF, EPUB and Kindle. Book excerpt: A small, rugged and relatively inexpensive velocity meter has been developed to measure uniform and oscillatory water flows in laboratory facilities. The Acoustic Doppler Velocimeter (ADV- 1) is capable of measuring three-dimensional velocities. The ADV- 1 measures velocities from 0 to 2.5 m/s at a sampling rate of up to 25 Hz. The measurements are made in a sampling volume located 5 cm in front of the probe. Since this instrument is new, the objective is to compare the ADV-1 with other laboratory current meters and prepare operational guidelines for the ADV-1 system. Three-dimensional velocities are measured in a wave tank with the ADV-1 horizontal velocity average 0.9 cm/s higher than the laser Doppler anemometer (LDA) and the ADV-1 vertical velocity average 0.93 cm/s lower than the LDA. A horizontal velocity profile is measured in a wave flume by the ADV-1 and a pitot tube, and the instruments differ by 3.5 %. Measuring velocity profiles around a stationary cylinder with the ADV-1 in the wave flume was highly successful, showing the ability of this instrument to measure velocities near structures in future laboratory research. The ADV-1 is portable and can be used for extended periods without recalibration. (jg).

This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field test program was conducted to evaluate the potential of two indirect wind sensing techniques as possible support in a warm fog dispersal system. The sensors examined were a Laser Doppler Velocimeter and an Acoustic Doppler Wind Sounder. Data from these devices were correlated with measurements taken by anemometers mounted upon a 61-m meteorological tower. The average deviation of the Laser Doppler Velocimeter was + or - 1.0 m/sec in wind speed and + or - 7 deg in azimuth. Five-minute averaging periods were taken and four to six altitudes were scanned during each run. The average deviation of the Acoustic Doppler Wind Sounder for 5-min averages was + or - 0.9 m/sec in wind speed and + or - 13 deg in azimuth. In one protracted run using 10-min averages, the deviations were + or - 0.6 m/sec in wind speed and + or - 6 deg in azimuth.

Book excerpt: The application of multibeam and sediment transport measurement technologies and the adoption of multi-faceted research methodologies have greatly advanced our understanding of the sedimentary processes on continental shelves in the last decade. This book uniquely blends cutting-edge research and state-of-the art review articles that take stock of new advances in multibeam mapping and sediment transport technologies, spatial analysis and modelling, and the applications of these advances to the understanding of shelf sediments, morphodynamics, and sedimentary processes. Case studies are also presented to illustrate the utilization of seabed property and process knowledge in habitat mapping and ocean management With its mix of papers focusing on technological advances, integration of shelf morphology and processes, and the application of these advances to coastal and ocean management, this Special Publication volume will serve as a milestone reference for professional marine scientists and as advanced text for students in marine geology, sedimentology and oceanography. This book is part of the International Association of Sedimentologists (IAS) Special Publications. The Special Publications from the IAS are a set of thematic volumes edited by specialists on subjects of central interest to sedimentologists. Papers are reviewed and printed to the same high standards as those published in the journal Sedimentology and several of these volumes have become standard works of reference.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geographic Information Technology have raised the expectations of users. A static map is no longer enough; there is now demand for a dynamic representation. Time is of great importance when operating on real world geographical phenomena, especially when these are dynamic. Researchers in the field of Temporal Geographical Information Systems (TGIS) have been developing methods of incorporating time into geographical information systems. Spatio-temporal analysis embodies spatial modelling, spatio-temporal modelling and spatial reasoning and data mining. Advances in Spatio-Temporal Analysis contributes to the field of spatio-temporal analysis, presenting innovative ideas and examples that reflect current progress and achievements.
