Estimation of wind speed and wave height during cyclones
(Elsevier, 2003)Wave and wind characteristics based on the cyclones, in the vicinity of the Nagapattinam coastline (east coast of India) were estimated. In all, 11 cyclones have crossed near the study region during 1960-1996. For the four ... -
Modeling of sediment transport along Mangalore coast using mike 21
(Allied, India, 2003)The objective of the present study is to understand the sediment transport along Mangalore Coast and to quantify the sediment transport rates. The data used in the present study includes Wave, Wind, Tide, Naval Hydrographic ... -
Performance of Honeywell silicon pressure transducers
(Allied, India, 2003)Simultaneous calibration of three Honeywell pressure transducers (PPTR) at four ambient temperatures have been carried out using a novel static calibration system developed in-house. Calibration results indicated that ... -
Delineation of high tide line using DGPS and laser trak instruments: With special reference to mapping techniqus
(National Institute of Oceanography, India, 2003)Delineation of High Tide Line (HTL), Low Tide Line (LTL) and demarcating the Coastal Regulation Zone (CRZ) boundaries for any part of the Indian coast has to be dealt with great care. This technical report suggests the ... -
An overview of the numerical and neural network accosts of ocean wave prediction
(Lanka Hydraulic Institute, Sri Lanka, 2003)This paper presents an overview of the development of the numerical wave prediction models and recently used neural networks for wave hindcasting and forecasting. The numerical wave models express the physical concepts of ... -
Field evaluation of navigational sensors using DGPS/GPS for a small AUV
(Allied, India, 2003)This paper presents the preliminary results of a field experiment for low-cost strap down IMU/GPS combination for the estimation of 2-D components of vehicle position (Trajectory). In present approach the effects of earth ... -
