Aerial photography was used to detect whether an entrance was trained and whether the rock protection occurred on both sides. For artificially opened entrances, coastal councils and DECCW regional offices were contacted for existing records and/or personal knowledge of the level at which the entrance is opened.;\n;\nTidal flow can be affected by breakwaters or training walls built to keep estuary entrances open and the artificial opening of lagoon entrances for flood mitigation, water quality, fish and prawn recruitment and other purposes. Both result in an increase in salinity levels, tidal ranges and flushing which can alter water quality, the distribution and composition of aquatic vegetation and animal species and ecological processes. Entrance training can also increase the erosion of inlet channels altering sediment processes and feeding back into even larger tidal ranges. Artificial opening at levels below natural can also lower frequency of inundation of peripheral vegetation such as saltmarsh and reeds.", "num_resources": 0, "num_tags": 0, "organization": {"id": "07979e16-5cbe-436c-9b35-6dd8c9d30512", "name": "oeh-office-of-environment-and-heritage", "title": "Office of Environment and Heritage (OEH)", "type": "organization", "description": "OEH cares for and protects NSW\u2019s environment and heritage, which includes the natural environment, Aboriginal country, culture and heritage, and built heritage.\r\n\r\nThe Office supports the community, business and government in protecting, strengthening and making the most of a healthy environment and economy in NSW.\r\n\r\nOEH also provides services and other support to the Royal Botanic Gardens and Domain Trust, NSW Environmental Trust, Western Sydney Parkland Trust, Parramatta Park Trust, Centennial Park and Moore Park Trust, Historic Houses Trust, Taronga Conservation Society Australia, Jenolan Caves Reserve Trust, and the Environment Protection Authority.\r\n\r\nSee: http://www.environment.nsw.gov.au/\r\n", "image_url": "2019-06-20-041940.170661Office-of-Environment-and-Heritage.jpg", "created": "2018-06-15T18:40:10.365903", "is_organization": true, "approval_status": "approved", "state": "active"}, "owner_org": "07979e16-5cbe-436c-9b35-6dd8c9d30512", "private": false, "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[154.0, -37.5], [154.0, -28.0], [148.0, -28.0], [148.0, -37.5], [154.0, -37.5]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[154.0, -37.5], [154.0, -28.0], [148.0, -28.0], [148.0, -37.5], [154.0, -37.5]]]}", "state": "active", "temporal_coverage_from": "2010-01-08", "title": "Estuary Entrance Condition", "type": "dataset", "unpublished": "false", "update_freq": "unknown", "url": null, "version": null, "extras": [{"key": "harvest_portal", "value": "SEED"}, {"key": "harvest_url", "value": "https://dataset-uat-new.stage.lz.seed.nsw.gov.au/dataset/estuary-entrance-condition03ad9"}], "resources": [], "tags": [], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "likes": 0, "tracking_summary": {"total": 0, "recent": 0}}}
