Beach processes between Mulgund and Shiroda, west coast of India
Study on beach processes for an year shows seasonal changes without annual net erosion. The beaches are stable and regain the maximum profiles during February to April. Distribution of longshore current direction is not ...
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. ...
Real time wave measurements and wave hindcasting in deep waters
Deep water waves off Karwar (lat. 14~'45.1'N, long. 73~'34.8'E) at 75 m water depth pertaining to peak monsoon period have been measured using a Datawell waverider buoy. Measured wave data show that the significant wave ...
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 ...
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 ...
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. ...
Analysis and design of instrumented subsurface mooring
(Surathkal: KREC, 1989)
The analysis and design of instrumented mooring is complex, since the environmental loading on the system may be static or dynamic and random. By using certain assumptions, an equivalent static loading system can be adopted ...
