This dataset contains:

-Supporting Material SM1, a table listing the initial conditions, design choices and available lidar datasets for each coastal wetland restoration scheme considered. The table contains for each scheme: Implementation date, Latitude/Longitude, Catchment area, Time embanked (with references), Policy context, Site aims, Number of breaches (if MR), Initial creek system, Design details, Other references, available lidar data at 1 m resolution

-Supporting Material SM2, a table listing the tidal data obtained for each site, including: HAT, Mean High Water Spring, Mean Low Water Spring, Mean Spring Tidal Range, Mean High Water Neap, Mean Low Water Neap and Mean Neap Tidal Range.

-Supporting Material SM3, consisting in 52 textfiles containing XYZ data that cover the extent and elevation of UK managed realignment schemes, for all study sites and all available years, after implementing preprocessing protocols 1-4 (stage 2).

-Supporting Material SM4, consisting in 52 textfiles containing XYZ data that cover the extent and elevation of creek networks as detected by lidar and our developed algorithm for all study sites and all available years (stage 3).

-Supporting Material SM5, consisting in 52 textfiles containing XYC data that cover the skeletonized creek network area as detected by lidar and our developed algorithm for all study sites and all available years, and gives the Reverse Strahler order of each branch (stage 3).

The figures are concatenated in a PDF file named SM6, and numbered Appendix A to E:

Appendix A is a table listing all results from the creek network morphometric analysis performed at 10 restored coastal wetlands in the UK, utilising the semi-automated creek parametrisation algorithm for each available lidar dataset. 

Appendix B consists of 10 figures showing the cross-sectional area evolution of the largest entry channel mouth for all sites and all available years.

Appendix C consists of 10 figures showing the evolution of creek morphometric parameters per RS order over the years, plotted against the 95% spread of natural creek parameters.

Appendix D consists of 10 figures showing the evolution of the creek extent, unchanneled length and overmarsh path length over the years for all sites

Appendix E consists of 10 figures showing the elevation gains and losses of all sites between the first and the last year considered, and correlates them to the initial site elevation and distance to creeks to analyse creek forming processes. The effect of creek proximity on the creek network is evaluated up to 20 m away from the creeks to reduce the impact of site elevation or of multiple creek influence on the results. Positive elevation changes are correlated to the most recent creek extent and negative elevation changes to the initial creek extent.
