Contaminant flow inside rivers or estuaries
In Vereeniging, 120 million litres of raw sewage is being discharge into the Vaal
River system every day (from http://thegreentimes.co.za/urgent-action-needed-to-

Boston’s John Hancock Tower (241 m, 60 floors) was originally vibrating excessively at wind speeds > 45mph and causing windows to fall (…became the “Plywood” palace!)

Civil, Architectural, and Environmental Engineers need to know how fluids flow, and how they affect or are affected by
objects in contact with them (or dispersed inside them), so that they design these objects properly, for un-interrupted and
safe function (or to provide better control of the dispersed substances)!
