Design of Breakwater with Permissible Overtopping Discharge Through Wave Flume Studies for the Development of Port
Rubblemound breakwaters are commonly provided for achieving wave tranquil conditions inside the port. The design of breakwater cross-section is complex as it involves various aspects such as wave-structure interaction, interlocking characteristics of armour and friction between different layers. The conceptual design of rubblemound breakwater will be evolved through several empirical formulae (such as Hudson and Van der Meer). The hydraulic stability of breakwater cross-sections would be confirmed through wave flumes/wave basins studies. This paper describes the details of the wave flume studies carried out for confirmation of hydraulic stability and permissible allowance of wave overtopping discharge to reduce the crest level of breakwater for the proposed development of Green field Port at Vadhavan, Maharashtra. These wave flume models are constructed to a geometrically similar (GS) scale based on ‘Froudian’ criterion of similitude. In order to optimization of breakwater design cross-sections to reduce cost of the project, the 2-D wave flume studies for confirmation of hydraulic stability and permissible allowance of wave overtopping discharge to reduce the crest level of breakwater have been conducted at CWPRS, Pune. The wave flume studies were conducted for combination of design wave height (DWH) at different water levels. The allowable overtopping discharge rate for safety shall be as per the specification in EurOtop 2008 & EurOtop 2018. The trunk portion of breakwater cross-section consists of 11 m3 ACCROPODETMII armour units placed at − 19.0 m bed level w.r. to CD. The top of the crest slab is at el. + 12.5 m level with a parapet top at el. + 15.0 m. The hydraulic stability tests were conducted in the wave flume by reproducing the sections to a geometrically similar (GS) model scale of 1:56 for trunk portion. The hydraulic stability of breakwater section was confirmed for design significant wave height (Hs) of 6.8–7.5 m. The model tray for collecting the overtopping discharge was fabricated at CWPRS laboratory and the overtopping discharge was collected, measured and confirmed with computational values.
