Department of Climate Change, Energy, the Environment and Water / Hydrographic Surveying for Tweed Sand Bypassing - 19-803

The Tweed River Entrance Sand Bypassing Project (TRESBP) is a legislated marine sand transportation project, which operates in perpetuity. The Project was established in the late 1990s to overcome the interruption of natural sand transport to the southern Gold Coast beaches of Queensland and improve conditions for navigation at the mouth of the Tweed River. Both these aspects were detrimentally affected by the extension of the river entrance training walls in the 1960s.

Under the project legislation, the TRESBPs two main objectives are:

1. Objective for Queensland: Achieve a continuing supply of sand to the Southern Gold Coast beaches at a rate consistent with the natural littoral drift rates, and supply of additional sand as required to restore and maintain the recreational amenity of the beaches;

2. Objective for New South Wales: Establish and maintain a navigable depth of at least 3.5 meters below Indian Spring Low Water (ISLW) and 70 meters wide in the approach and entrance channel to the Tweed River; Monitoring of environmental conditions is essential in ensuring that the project meets the above objectives and also allows for a greater understanding of coastal processes which can lead to project improvements and innovation.

The expected outcomes will be the delivery of accurate survey data utilising specialised surveying equipment through the engagement of suitably qualified and registered surveyors for hydrographic and land surveying works. The survey works are essential to comply with the Tweed Sand Bypassing environmental conditions of approval. Data will be used for the mapping and monitoring of bathymetric conditions within the project area which will be linked to the local coastal processes.

Department Planning, Industry & Environment will be closed over Christmas from 23/12/19 - 3/1/2020 - any enquiries during this period will be addressed upon return 6 January 2020.

You must have a CPHS Level 1 hydrographic surveyor overseeing all of the hydrographic surveying projects and sign off on final records. It is expected that the Level 1 will attend key phases of bathymetric survey activity specifically, mobilisation and set to work validations/calibrations. You must have a CPHS Level 2 hydrographic surveyor as a survey team member should the Level 1 not be on-site on a continual basis.
