Caption: Coastal sediment deposition modelling. Researchers working on a water tank model of the Somme Bay in France. This model is being used to simulate the rate of deposition of river sediment, a process known as silting. The bay has a surface area of 60 square kilometres, and some 700,000 cubic metres of sediment are deposited every year. The rate of silting is increased by the construction of dams and polders, threatening the shellfish farms. This study (on a scale of 1 to 350) simulates in one day the effects of tides over a whole year. Photographed at SOGREAH (Company for Studies and Hydraulic Applications), in Grenoble, France.
