The second in a four-volume study to assist the Netherlands government in a policy analysis of alternative control strategies for operating the storm-surge barrier across the Oosterschelde basin. This volume describes the sensitivity analysis and shows why two specific strategy representations were selected for further evaluation from the three promising barrier control strategies. It explores the effects on performance of varying specific elements of the control strategies: basin inside water levels, their durations, and head differences across the barrier while closing and while closed. Inside water level and duration are surrogate measures for the impacts discussed in Vol. I--dike safety, ecology and commercial fishing, and water management and shipping. Head difference is used to assess impacts on barrier loads.
