IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Als a coastal engineering model for wave propagation, wave-structure interaction and bed morphology evolution
Author : Th. V. Karambas , E. Koutandos , N. Kampanis
In the present work the integrated coastal engineering numerical model ALS is presented (the name ALS becomes from the ancient Greek word αλς which means sea). The model simulates the linear wave propagation, wave induced circulation, sediment transport and bed morphology evolution. The model consists of three main modules: WAVE-LS, WAVE-L and COAST. The Large Scale module WAVE-LS is based on the numerical solution of the directional wave energy balance equation. The nearshore wave transformation module WAVE-L is based on the hyperbolic type mild slope equation and is valid for a compound wave field near coastal structures where the waves are subjected to the combined effects
of shoaling, refraction, diffraction, reflection (total and partial) and breaking. Radiation stress components (estimated from the Large Scale module as well as from the hyperbolic wave module) drive the depth averaged circulation module COAST for the description of the nearshore currents and sediment transport in the surf and swash zone. The module COAST is coupled with a 3D bed evolution module to predict coastal bathymetry changes.
