South Humber Gateway

Degree of synergistic effects and conflicts according to WFD aims

This measure was all about the creation of new intertidal habitat which provides a much needed habitat in the Humber Estuary to give land back, which can be utilised as natural flood defence and to provide extra space within the Estuary, which in turn can also improve water and sediment quality and reduce sedimentation in the main channel, which in turn reduces dredging requirements.

S.I. 1.1 Habitat loss and degradation during the last about 100 years: Intertidal       X   Development of intertidal habitat.
S.I. 1.5 Gross change of the hydrographic regime during the last about 100 years       X   Opportunity for additional space along the Humber Estuary. 
S.I. 3.1/3.2 Decrease of water and sediment chemical quality       X   Intertidal habitat and wetlands have the potential to improve water and sediment quality. 
D.I. 1.3 Land claim during the last about 100 years       X   Land given back to the Humber Estuary.
D.I. 1.7 Relative Sea Level Rise       X   Opportunity to provide natural defence against flooding in line with increased sea level rise. 
D.I. 2.4 Maintenance dredging       X   Fewer requirements for dredging as sedimentation occurring through accretionary trends in intertidal and saltmarsh habitats.
