In an uncertain environment like this more flexible measures are needed. Also, the time between design-survey and approval of dredging proposals needs shortening, as the river morphology changes fast. Close monitoring and associated modelling has led to new insights into the behavior of the river. This examples shows that the approach promoted by Building with Nature and applied here can give a technically sustainable solution. Due to governance complications, however, this particular project could not be shown to be sustainable in the long run.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After three years of dredging the river discharge had increased and the river was flowing all year round, thus increasing its navigability.
