Coastal Research and Modelling Services utilises historical maps and aerial photographs to track long-term changes in coastal morphology:

1. Time-series comparisons of maps and satellite imagery reveal trends in erosion, accretion, and land loss over decades.

2. Photo archives, including early aerial surveys and satellite data from the 1970s onward, allow visualisation of shoreline retreat, marsh fragmentation, and infrastructure impacts.

3. Datasets are georeferenced and layered with modern imagery to assess the spatial and temporal evolution of coastal features.

Coastal Research and Modelling Services provides actionable advice by interpreting these datasets to understand:

1. Sediment transport and deposition.

2. Storm surge and tidal dynamics, which influence erosion and habitat loss.

3. Human impacts, such as dredging, levee construction, and land use changes, which alter natural coastal processes.

The insights from Coastal Research and Modelling Services are used by:

1. Environmental managers to guide wetland restoration and sediment diversion projects.

2. Policy makers to prioritise funding and infrastructure based on vulnerability assessments.

3. Researchers to model climate adaptation strategies and ecosystem resilience.
