Dutch Delta Plan

Hawkes, Nigel. Structures TheWay Thin Are Built. 1990. Reprint. New brk Macmillan, 1993. Discusses many weU-known civil engineering projects. Chapter 4 contains information about seventeen projects, including the Great Wall of China, the Panama Canal, and the Dutch Delta Plan. Contains illustrations and discussion of the effect of the projects. 

In estuaries trace metal chemistry intensive studies have been devoted to the distribution of heavy metals between dissolved and suspended matter phase, the special influence of phytoplankton population and the complicated heavy metal concentration regulation in the estuarine water column affected by the salinity gradient and resuspension and solubilization phenomena. Detailed long-term studies are investigating the situation and its seasonal dependence in various parts of the Oosterscheldt in connection with effects exerted by the completion of the Dutch Delta Plan[42,43,44]. The influence of the dry and wet season have been studied in an African tropical estuary[44]. 

The Zuiderzee reclamation was easily the largest effort by the Dutch to reclaim lost land. The Delta Project was the largest coastal flood protection project ever attempted by the Dutch. These two projects are similar in many ways. Both were initially planned without any urgency until a flood event sent the plans into action. Both projects were developed in stages allowing new developments to alter the plans as time went by. And, both projects took longer to complete than originally planned.
