When an architect is designing a building, they build a scale model to check how their design will work as an actual physical structure. What happens, however, when engineers are designing things that will have to be compatible with the currents in rivers ... things like dams, bridges, or pump stations? Well, that’s where water resources engineering firms like Northwest Hydraulic Consultants (NHC) come into the picture. Their work often includes building exact miniature recreations of waterways, complete with flowing water. We recently caught up with NHC principal Darren Shepherd, who guided us through the production process of one of his more exciting models – a one-twelfth scale Norwegian whitewater kayaking park.
