Approximate equations at breaking for nearshore wave transformation coefficients
(NIO, Goa, 1991)Based on small amplitude wave theory approximate equations are evaluated for determining the coefficients of shoaling, refraction, bottom friction, bottom percolation and viscous dissipation at breaking. The results obtainEd. ... -
Morphological changes at Godavari delta region due to waves, currents and the associated physical processes
(Geological Society of India, 1991)Wave conditions, the most important in coastal modification, prevailing in the region of Godavari Delta for different seasons are illustrated. The analysis of GEOSAT altimeter data for the period November 1986 to October ... -
Implication of thermal discharges into the sea - A review
(Kalpana Corporation, 1991)The adverse effects of thermal discharges into coastal waters from power plants have been reviewed. The direct and indirect impacts of thermal pollution to marine biota have been discussed briefly. The tolerance limits ... -
Current measurements over the western continental shelf of India
(Pergamon, 1991)Current meter observations obtained from a site off Goa (15 degrees 08'N, 73 degrees 16'E) over the western continental shelf of India are presented. Data were collected from the site during three different months in a ... -
Wave statistics around the Indian coast based on ship observed data
(NISCAIR, New Delhi, 1991)Wave characteristics around the Indian Coast are discussed based on the ship reported wave data compiled over 19 y (1968-1986). This data have been compared with instrumentally measured waves at 2 locations (Kakinada on ... -
Wave measurement in severe ocean currents
(Institution of Engineers, India, 1991)The measurement of ocean waves has been of particular interest, as wave data and understanding of wave phenomena are essential to ocean engineering, coastal engineering and to many marine operations. The National Institute ... -
Marine meteorology and fisheries
(NIO, Goa, 1991)Weather conditions over the sea affect the fisheries both directly and indirectly. Fishing activity gets hampered even at moderate sea state conditions, and under low winds, if the swell is predominant in the operational ... -
Ocean wave nonlinearity and phase couplings
(NISCAIR, New Delhi, 1991)Bispectrum of a swell dominated sea state is computed using Fourier coefficients from an original record and from simulated Fourier coefficients using pseudorandom (uniform) phase spectrum. The differences in the bispectra ... -
Wind-driven coastal upwelling along the western boundary of the Bay of Bengal during the southwest monsoon
(Pergamon, 1991)A hydrographic survey during the southwest monsoon (July-August 1989) showed that along most of the western boundary of the Bay of Bengal, in an approximately 40 km wide band, isopycnals from depths up to about 70 m surfaced ... -

The warm pool in the Indian Ocean
(Indian Academy of Sciences, 1991)The structure of the warm pool (region with temperature greater than 28 degrees C) in the equatorial Indian Ocean is examined and compared with its counterpart in the Pacific Ocean using the climatology of Levitus. Though ... -
Flushing characteristics of Amba river estuary, west coast of India
(NISCAIR, New Delhi, 1991)Tide dominated Amba River Estuary was studied to evaluate its flushing characteristics. Although, spring tidal range of 3.4 m was observed at 40 km inland, the seawater component here at high tide was less than 1%. The wet ... -
Shallow water tides

Buoyancy package for self-contained acoustic doppler current profiler mooring
(NIO, Goa, 1991)A buoyancy package for self-contained Acoustic Doppler Current Profiler(SC-ADCP 1200 RD instruments USA) was designed and fabricated indigenously, for subsurface mooring in coastal waters. The system design is discussed. ... -
Association between premonsoonal SST anomaly field in the eastern Arabian Sea and subsequent monsoon rainfall over the west coast of India
(NISCAIR, New Delhi, 1991)Interannual variability of premonsoonal (April-May) surface heat flux parameters together with sea surface temperature (SST) anomaly field in the eastern Arabian Sea has been examined for the period 1975-1984 in relation ... -
Estimation of directional wave spreading
(NIO, Goa, 1991)Directional properties of ocean waves are of great economic interest. The knowledge of wave directionality is important for the design of maritime structures and offshore operations. Two main aspects are considered for ... -

The coastal current off western India during the northeast monsoon
(Pergamon, 1991)Hydrographic data collected during December 1987 and January 1988 are used to describe the poleward coastal current along the west coast of India that flows against weak winds during the northeast monsoon. Near the southern ...
