Abstract
"ENGINEER", established in 1973 by The Institution of Engineers, is a Journal for dissemination of Engineering knowledge, published quarterly.If you are interested in contributing an Original Technical Paper based on research by the author(s) (intended for Section I) or an Original Article of Professional or Technical interest related to Engineering. (Section II) to this journal please go through the publication checklist which can be downloaded from here.Cover DescriptionCover images show a few views of the Maduru Oya reservoir and construction of right bank canal. The Institution of Engineers, Sri Lanka, acknowledges Eng. L.D. Amila Sanjeewa of the Department of Irrigation for providing images and related information of the project.
Highlights
Various methods are being used to mitigate coastal erosion due to both natural and manmade causes around the world
For waves propagating over an impermeable bed, Nwogu [5] showed that if a proper zzαα is used, the range of applicability of the Boussinesq-type equations can be extended to intermediate water depths
The predictive skills of a Boussinesq-type model for simulating wave transformation over porous beds are evaluated with a particular emphasis on the influence of model parameters αα and ββ on the wave height distribution
Summary
Various methods are being used to mitigate coastal erosion due to both natural and manmade causes around the world. Some resort to soft measures such as beach nourishment, berm management, etc., and some tend to rely on hard measures such as offshore breakwaters, seawalls, revetments etc Many of these hard measures involve structures, a solid understanding of their interaction with waves is vital. The recent developments in wave theories and numerical models have substantially helped coastal researchers to study the evolution of waves and currents in the vicinity of solid structures but not to the same extent when it comes to porous ones. This is primarily due to the uncertainty in determining a few empirical coefficients associated with porous media
