Abstract

Bellarine Bayside is a Victorian government appointed committee of management that manages 17 kms of coastal reserves along the northern Bellarine Peninsula on the western coastline of Port Phillip Bay. In order to obtain quality data on sediment movement along the shoreline across temporal and spatial scales, Bellarine Bayside has recently implemented a citizen-science community coastal monitoring program titled Beach Watch. The program incorporates many social and community objectives.

Dedicated Beach Watch community volunteers regularly measure beach profiles at 20 strategically selected monitoring locations. To ensure the data is scientifically rigorous, quality control measures have been incorporated into the survey methodology and volunteers are provided with a step-by-step manual; maintained monitoring kits; regular training; and assistance every step of the way.

At each monitoring location a marker post has been installed to provide the AHD benchmark height. When measuring profiles, volunteers use an optical dumpy level and survey staff to measure elevations along a set transect which extends from the beach back shore to the inter-tidal zone. Height measurements and beach substrate data is recorded at no greater than 2 metre intervals along the transect. Raw data is submitted to staff who check and process the data using a pre-designed Microsoft Excel template, which generates the profile.

Next steps for Beach Watch is to investigate the development of a simple data base to store and help analyse the information and to incorporate other monitoring techniques such as photo-point monitoring and drones.
