text: Depending on circumstances, various hydrological, environmental, ecological, and economic side effects can be realised by the implementation of a tidal inlet closure, including:
  * change of tide (amplitude, flows) at the seaward side of the dam
  * change in bar and gully topography, outside the dam
  * removal of tides on the inner side of the dam
  * change in groundwater level in adjoining areas
  * alteration of drainage capacity for adjoining areas
  * loss of fish and vegetation species
  * loss of breeding and feeding areas for water birds
  * rotting processes during change in vegetation and fauna
  * stratification of water quality in stagnant reservoir
  * accumulation of sediments in the reservoir
  * impact on facilities for shipping
  * impact on recreation and leisure pursuits
  * change in professional occupations (fishery, navigation)
  * social and cultural impacts.
