East Yorkshire coastal erosion

activity index






Measurement of cliff loss is normally carried out during autumn and spring in order to capture change over summer and winter.

Seasons of coastal erosion vary considerably in intensity across the years. It is sometimes helpful to have an idea of activity in terms of loss for comparative purposes.

Each entry represents a seasonal total of cliff loss in rounded metres for all unprotected monitoring profiles. A value of 105, or 104 from May 2014, would mean a hypothetical loss of one metre for the half year along the entire coast.

No survey was conducted during autumn 2016 because of poor weather conditions. The cumulative total for the year is split 2:1 over the seasons.

Averages values: autumn = 57, spring = 121, all = 88.
