    Hydraulic Performance of ‘HOBO’ units
    (2015-08-03) Odara, MGN; Hettiarachchi, SSL; Mirihagalla, PD
    The paper presents the results of a detailed two dimensional model investigation of a rubble mound breakwater armoured with Hollow Block (HOBO) concrete armour units, with respect to the hydraulic performance. The results of the model investigations are analysed to obtain graphical and numerical relationships between the energy dissipation, wave reflection, energy transmission, wave steepness, wave period, Iribarren number and the section properties of the breakwater.

    Hydraulic performance of rubble mound breakwaters
    (Department of Civil Engineering, University of Moratuwa, 2014-03) Hettiarachchi, SSL; Odara, MGN; Godagedara, TH; Herath, HHHB; Hettiarachchi, MTP
    Breakwaters are widely used to mitigate the adverse impacts of ocean wave action. Breakwater failures that occurred during late seventies and early eighties, have highlighted the need for further investigations on breakwaters in terms of their hydraulic performance. This paper presents the hydraulic performance of conventional rubble mound rock armoured breakwaters and concrete armoured rubble mound breakwaters, statically stable berm breakwaters and reshaping berm breakwaters based on the re-analysis of large scale model tests.
