Tidal flat and salt marsh response to hydrodynamic forcing

Abstract

Loan 1072 was used to initiate a 2-year measurement campaign on Campfield Marsh, Cumbria. The campaign ran from Spring 2017 until Spring 2019, with the objective of gathering very high resolution topographic data from 4 sites on Campfield Marsh. Loan 1072 allowed the deployment of of a terrestrial laser scanner (TLS) and relative carrier phase GNSS (RCP-GNSS) in March, June and October 2017. Further data were collected under Loan 1091. Due to bad weather conditions, no data was collected in March 2017. Here, we present the measurements taken in June 2017. These data constitute the baseline for our topographic analysis of marsh evolution, which will be presented in the scientific report for Loan 1091. Our preliminary findings show that specific features need to be monitored to understand the evolution of marsh margins. Specifically, the diameter and shape of vegetation patches as well as the scarps and their fronting pool systems will be the focus of the following loan (Loan 1091).
