This paper focuses on the risk assessment of a new type of concrete artificial fish-reefs in Shengsi when typhoon waves with the lowest water level and maximum tidal current speed occur.

Model tests were carried out on the stability of a new type concrete block revetment under regular and irregular waves in a wave flume.

An accurate and efficient method for computing Sommerfeld type integrals is crucial in the analysis of the electromagnetic waves for radiators and scatters in the presence of a conducting half-space.
