This paper describes a new armour unit called XP-Overtop which is applied together with XblocPlus units in modular layer order to reduce wave overtopping. placed close the crest of structure. Physical model tests have been performed study hydraulic stability and overtopping reduction as function relative freeboard. Based on performed, following conclusions can be drawn: 1) XPOvertop generates s...

Dhaka-Narayanganj-Demra (DND) Project is one of about 700 water sector projects built by Bangladesh Water Development Board (BWDB) in Bangladesh. It was a successful project from all considerations. But during 1998 flood, there was overtopping and breaching of embankment. At that time BWDB was able to stop much inundation by doing emergency work. Still many people are building their houses and ...

Wave absorbers installed in front of revetments are effective reducing wave overtopping and inundation caused by periodic waves. The absorbers’ mechanism long-period waves such as tsunamis storm surges is not clearly understood. This study conducted a physical modeling test numerical analysis based on large eddy simulation model using in-house code to examine the characteristics according revet...

Impulse waves feature tsunami-like characteristics and are generated by very rapid mass wasting, including landslides avalanches, into water bodies. In engineered reservoirs, these may run up overtop the dam, thereby exerting hydrostatic dynamic forces on its structure. For this work, solitary were applied as a proxy for impulse acting vertical structures during wave run-up overtopping investig...

In this paper existing guidelines to predict wave overtopping on rubble mound breakwaters and coastal structures are modified improved with respect the influence of roughness crest width. Data from recently made model tests data combined demonstrate need for modifying these formulations in EurOtop. A new reduction factor γcw width is established an improvement method by Besley. The slope normal...

This study attempts to refine a model named the Integrated Formula of Wave Overtopping and Runup Modeling (IFORM) improve prediction performance mean wave overtopping discharge for broader range installation conditions. The empirical formula describing relation between maximum runup has been re-examined. A set piecewise formulas is implemented in IFORM by optimal reconstruction coefficients dep...
