A review and re-assessment of sediment transport along the Goa Coast, India
(Coastal Research Foundation, 2002)Although, a variety of methods have been employed to determine sediment transport along Goa coast, India, the results differ in some sections. Fifteen studies have been reviewed, compared, re-assessed and a corrected shore ... -
A shallow seismic reflection study of the Gulf of Kutch, northwest India - Observations on its structural evolution
(Elsevier, 1988)A study of echosounding (678 line km) and shallow seismic reflection (180 line km) records of the E-W trending Gulf of Kutch, India showed the following features: The gulf margins in the east, and partly in the southeast ... -
Coastal processes and longshore sediment transport along Kundapura coast, central west coast of India.
(Elsevier, 2014)Longshore sediment transport (LST) is one of the main factors influencing coastal geomorphology. This study examines the variation in the LST estimate using four well known formulae and the sensitivity of wave parameters ... -
Cochin backwaters: An introduction to the system, prior studies, historical trends and future implication
(Kalpana Corporation, Varanasi, India, 1994)Studies over the last 2 decades in the Cochin backwater system in India are reviewed to have an integrated profile with a point to evaluate future development projects in terms of potential consequences to the estuarine ... -
Distribution and origin of seamounts in the central Indian Ocean Basin
(Taylor and Francis, 2005)Approximately 200 seamounts of different dimensions have been identified, from multibeam bathymetry maps of the Central Indian Ocean Basin (CIOB) (9 degrees S to 16 degrees S and 72 degrees E to 80 degrees E), of which 61% ... -
Exploring the oceans- The geophysical way
(Current Science Association, Bangalore, India, 1993)The evolution of the eastern continental margin of India (ECMI), the Bengal Fan and the Central Indian Basin (CIB) is a consequence of the breakup of India from the eastern Gondwanaland in Late Jurassic to Early Cretaceous. ... -
Geomorphology and geology of the Bay of Bengal and the Andaman Sea
(Oxford and IBH, New Delhi, 2001)Marine geological studies in the Bay of Bengal were initiated by the Andhra University in early 1950's and have subsequently become widespread during the International Indian Ocean Expedition (IIOE - 1962-65). Geomorphological ... -
Geomorphology and surficial geology of the western continental shelf and slope of India: A review
(Current Science Association, Bangalore, 1997)Coastal geology and geomorphology of the area and nearshore currents played a significant role in the distribution of placer minerals off Kerala and Maharashtra. Transport and sedeimentation of fine-grained materials at ... -
Geomorphology of the Goa Coast
(Indian Academy of Sciences, Bangalore, 1982)This paper is based on the observations and interpretations of aerial photographs (1;25, 000 and 1:15, 000) of the Goa Coast. Aerial photocharacters like zonal differences, texture, shape, size, form, pattern, vegetation, ... -
Hydrodynamic and geomorphic controls on the morphology of an island ecosystem in the Vembanad Lake, West Coast of India
(The Coastal Education and Research Foundation, 2008)Textural characteristics of the surficial sediments around Perumbalam Island located within the Vembanad Lake, southwest coast of India, were studied on a seasonal basis to understand the geomorphic response of the region. ... -
Influence of seamount topography on the local facies variation in ferromanganese deposits in the Indian Ocean
(Elsevier, 1988)The morphology and chemistry of ferromanganese nodules and encrustations from a seamount in the Central Indian Ocean Basin show local variations. Nodules from the summit of the seamount have sporadic distribution, are less ... -
Influence of sedimentation on the geomorphology of the northwestern continental margin of India
(Taylor and Francis, 2000)Based upon the analysis of about 10,000 line km of echosounding and bathymetric data and variations in mass accumulation rate along the NW continental margin of India (between Kori creek and Mumbai), which has deduced in ... -
Influences of Holocene sea level, regional tectonics, and fluvial, gravity and slope currents induced sedimentation on the regional geomorphology of the continental slope off northwestern India
(Elsevier, 1993)Regional geomorphology derived from echosounding and bathymetric data (lines of a total of 12,000 km), depth to basement, regional deep seated tectonic features, surficial sediment distribution and Holocene sedimentation ... -
Interpretation of aerial photographs of Ratnagiri Bay - a case study
(CSIR-NISCAIR, 1987)Aerial photocharacteristics like tonal difference, texture, shape, size, form, pattern, vegetation, soil characteristics and associated features were used to identify fluvial, marine and aeolian features such as tidal ... -
Marine investigations in the Lakshadweep Islands, India
(Antiquity Trust, 1999)The Lakshadweep Islands lie on the sea route between West Asia and Africa on the one hand and South Asia and the Far East on the other. In maritime history, these islands have played a vital role by providing shelter, fresh ... -
Morphological variations in the polymetallic nodules from selected stations in the Central Indian Ocean
(Springer, 1987)Polymetallic nodules from the Central Indian Ocean largely range in size from 2 to 6 cm. The smaller nodules (4 cm) are subspheroidal to spheroidal in shape and with the increase in size, nodules become more discoidal and ... -
Morphology of a coral bank, western continental shelf of India: A multibeam study
(Geological Society of India, 1993)Morphology of a living coral bank (Gaveshani Bank) is described using multibeam swath bathymetric survey system Hydrosweep. The bank has a height of 42 m, length of 2 km and a maximum width of 1.66 km, with steep flanks ... -
Morphology of an uncharted seamount from Central Indian Basin
(Elsevier, 1989)The morphology of a seamount at 12 degrees 35'S and 76 degrees 16'E is studied. This conical seamount has a maximum height of 1275 m (water depth 4135 m) and covers an area of about 189 sq km. The maximum basal extension ... -
On the role of geometry of cross-section in generating flood-dominance in shallow estuaries
(Academic Press, 1992)Shallow estuaries often show tidal asymmetry of flood-dominance in which duration of the flood is shorter and its peak discharge larger than the corresponding values during ebb. A simple analytic model for this phenomenon ... -
