Degree of synergistic effects and conflicts according to WFD aims
This measure was about the creation of new intertidal habitat which provides a much needed habitat in the Humber Estuary and allows land to be used as a natural flood defence, which in turn can also improve water and sediment quality and reduce sedimentation in the main channel, which in turn reduces dredging requirements. The compensation measure was not designed to meet the requirements of the Water Framework Directive (WFD). However, it covers two of five main pressures the polyhaline zone of the Humber estuary is affected by.
