Wave directional spreading at shallow and intermediate depth
(Cent. for Earth Sci. Stud., Cochin (India), 1997)
Based on wave measurements carried out at shallow and intermediate water depths variation of directional spread parameter 's' is studied. A comparison of the mean wave directional and principal wave direction shows that ...
Spectral representation of measured shallow water waves
(CWPRS, Pune, 1994)
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. ...
Autoregressive modelling of measured sea waves off west coast of India
(Brazilian Water Resources Association, Brazil, 1995)
The spectral analysis of measured sea waves can efficiently be carried out by the Fast Fourier Transform (FFT) technique. Even though many present techniques can be used for the generation of time series on sea waves from ...
Variation of longshore current and sediment transport along the south Maharashtra coast, west coast of India
(NISCAIR, New Delhi, 1993)
The longshore current velocity varied between 0.1 and 0.33 m.sec/1. The longshore current direction was predominantly southward at Ratnagiri, Ambolgarh (Maharashtra, India), whereas it was variable at Vengurla during the ...
Dredge spoil disposal off Kavaratti Island, Lakshadweep, India
(NISCAIR, CSIR, 1996)
Maintenance dredging has been carried out along the navigational channel at Kavaratii Island and dredge spoil is disposed in the open sea. This paper describes the movement of sediment plume while dredging and disposal. ...
Field measurement on longshore current variation between Ratnagiri and Mangalore, west coast of India
(CWPRS, Pune, 1992)
The daily measurements on longshore current velocity and direction were carried out at selected 12 stations along the coast between Ratnagiri and Mangalore, India. The directional wave data measured at Karwar were used to ...
Response of surface buoy moorings in steady and wave flows
(Oxford and IBH, New Delhi, 1992)
A numerical model has been developed to evaluate the dynamics of surface buoy mooring systems under wave and current loading. System tension response and variation of tension in the mooring line at various depths have been ...
Wave refraction and prediction of breaker parameters along the Kerala Coast, India
(NISCAIR, CSIR, 1997)
Numerical wave refraction study for the Kerala Coast has been carried out for waves representing southwest monsoon (June-September), northest monsoon (October-February) and fair weather period (February-May). Distribution ...
Coastal processes along the shorefront of Chilka Lake, east coast of India
(NISCAIR, New Delhi, 1993)
Chilka Lake (Orissa, India) inlet mouth is exposed to high annual littoral drift of about 1 x 10 super(6) m super(3). The inlet mouth was observed to migrate about 500 m northward during the period of one year study. ...
