    • Variations in wave direction estimated using first and second order Fourier coefficients 

      SanilKumar, V.; Anand, N.M. (Elsevier, 2004)
      In most design applications such as alignment of the berthing structure and breakwater alignment, it becomes necessary to determine the direction of design wave. There are two different approaches to determine wave direction. ...
    • Wave characteristics in the sea around the Andaman and Nicobar Islands 

      Gouveia, A.D.; RamaRaju, D.V.; Murty, C.S. (CSIR-NISCAIR, 1981)
      Wave data were collected during 51 and 52 cruises (Feb. 1979) and 66 and 67 cruises (Jan. 1980) of R.V. Gaveshani using a shipborne wave recorder. Some wave records were also obtained along the 5 degrees 30'N lat. from ...
    • Wave climatology of the Indian Ocean derived from altimetry and wave model 

      Vethamony, P.; Rao, L.V.G.; Kumar, R.; Sarkar, A.; Mohan, M.; Sudheesh, K.; Karthikeyan, S.B. (NIO, Dona Paula, Goa (India), 2000)
      GEOSAT altimeter data for the period 1986-1989 have been utilised to derive wave climatology for the Indian Ocean region bounded by 20 degrees S to 25 degrees N and 40 degrees E to 110 degrees E. The results are presented ...
    • Wave directional spectrum from array measurements 

      Fernandes, A.A.; Sarma, Y.V.B.; Menon, H.B. (Allied, Chennai (India), 1996)
      Using the method of Esteva (1976, 1977), whcih assumes that at the frequency band the waves approach from just a single "mean" wave direction, wave direction has been consistently, accurately and unambiguously evaluated ...
    • Wave directional spreading at shallow and intermediate depth 

      SanilKumar, V.; Deo, M.C.; Anand, N.M. (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 ...
    • Wave forecasting in near real time basis by neural network 

      Rao, S.; Mandal, S.; Prabaharan, N. (Allied, Chennai, 2001)
      In modern age, the human settlements and activities are very much increasing near the oceanfront. In order to cope up with the need such as construction of jetties, harbours, offshore berths, offshore platforms, navigation ...
    • Wave Observations in the Mahanadi Basin (Bay of Bengal) during September 1980 

      Fernandes, A.A.; Gouveia, A.D.; Sathe, P.V.; Nagarajan, R. (Indian Association for Limnology and Oceanography, 1981)
      The sea state at the location 20 degrees 21'E, 87 degrees 10'N (40 m depth) is described for the periods September 7-11, 1980 (calm) and September 16-18, 1980 (stormy) from the results of spectral analysis and wave by wave ...
    • Wave Persistence in Central Bay of Bengal during the Southwest Monsoon 

      Sathe, P.V.; Gouveia, A.D. (Indian Association for Limnology and Oceanography, 1982)
      Wave data collected on board RV @iGaveshani@@ in central Bay of Bengal during Monex-79 are analysed for significant wave height (H@ds@@), average period (T@dc@@), zero-crossing period (T@dz@@) and spectral width parameter ...
    • Wave refraction and prediction of breaker parameters along the Kerala Coast, India 

      Sajeev, R.; Chandramohan, P.; SanilKumar, V. (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 ...
    • Wave transmission by suspended pipe breakwater 

      Mani, J.S.; Jayakumar, S. (American Society of Civil Engineers, 1995)
      A suspended pipe Breakwater was designed specifically for fishery/pleasure-craft harbors where moderate wave agitations in the harbor basin are admissible. The present breakwater consists of a row of closely spaced pipes ...
    • Wavelength of ocean waves and surf beat at duck from array measurements 

      Fernandes, A.A.; Menon, H.B.; Sarma, Y.V.B.; Jog, P.D.; Almeida, A.M. (American Society of Civil Engineers, Virginia, USA, 2001)
      Wavelength of ocean waves and surf beat (infra gravity waves) has for the first time been computed as a function of frequency from different combinations of non-collinear 3-gauge arrays. Data at the 15-gauge polygonal array ...
