๐ Monthly Research Spotlight - Assessing Sedimentation and Siltation dynamics in the Exe Estuary 2024 โฑ๏ธ
โฐ This recent EEMP study brings together existing research, surveys and data to better understand how sediment moves around the Exe Estuary and how it is changing over time.
๐ The study combined LiDAR surveys, bathymetry mapping, historical charts and sediment core sampling to build a clearer picture of how the estuary has evolved and continues to
๐ Key findings include:
โ
The estuary is a highly dynamic system, constantly reshaped by tides and waves
โ
Around 1.5 million mยณ of sediment has been lost since 2007
โ
Most sediment comes from marine (sea) sources, not rivers
โ
Channels, sandbanks and shorelines are continually moving and changing
๐ Study rationale โ Why?
โข Helps understand long-term erosion and sediment change
โข Supports safe navigation by tracking channel movement
โข Protects important wildlife habitats and feeding grounds
โข Informs flood risk management and coastal defence
โข Guides future sustainable estuary management
๐ข The study highlights the need for continued monitoring and research to better understand sediment sources and manage this ever-changing environment. ๐ข
