Wind Surge: Interactive On-line Mac and PC
This material was originally created for
Starting Point:Introductory Geology and is replicated here as part of the SERC Pedagogic Service.
Summary
Wind surge (more info) is a JAVA based applet for exploring how water level on the windward and leeward side of a basin depends on wind speed, basin length, water depth, and boundary type. Theoretical discussion is provided.

Assessment
Student problem: Assess the effect of varying the windspeed on the surge elevations for a given basin geometry. Do the same with the water depth and basin length for a fixed wind speed. Plot your results.
Student problem: Examine the influence of the end wall. Find a basin size and wind speed such that a given wall height is overtopped (note: if overtopping occurs, the word 'overtopping' is written next to the eta(l) value.) Then, increase the wall elevation until overtopping stops. Explain the difference in results.
