PHYSICAL EVALUATION OF THE HYDRODYNAMIC STABILITY OF AN ECO-ENGINEERED ARMOURING UNIT

ECOncrete®‘s Coastalock is an ecologically designed armour unit, providing alternative and/or a complement to traditional layers with enhanced armouring that provides shoreline stabilization, while also creating well-defined local ecosystems mimic natural rock pools. The 2D physical model tests performed at TU Delft focused on the stability, reflection and overtopping of slope regularly placed single layer armour. 2V:3H had impermeable core, no wave breaking foreshore toe. stability was seen double, number Ns (Ns= Hs/ΔDn50) increasing from roughly 2 4 above, by porosity between blocks spacing units 0percent 25percent. So less concrete use led more stability. mean discharge could be characterized roughness factor gamma_f = 0.610 (for 25percent spacing). A key goal development demonstrate innovative eco-engineered unit design it now possible add ecological considerations into process promote biodiversity provide ecosystem services, achieving both structural goals.
