Sources of change to the hydrology:

  • Water extraction (both surface and groundwater) and impoundment reduce the amount of water entering a wetland
  • Point sources can increase water flows to wetlands.
  • Livestock (both domestic and feral) can reduce the amount of water present in a wetland through drinking and disturbance (resulting in increased evaporation).
  • Activities that change the wetland form, such as excavation, drainage, infrastructure and land forming/reclamation, result in altered hydrology of the wetland.
  • Clearing of vegetation and soil compaction/impervious surfaces (urbanisation) result in increased surface water flow and often decreased groundwater recharge.
