Lake bed geomorphology and sedimentary processes in glacial lake Windermere, UK
A 1:10,000 map of the geomorphological features and sedimentary processes shaping the landscape is presented for Windermere, the largest lake in the English Lake District. High-resolution multibeam bathymetry and backscatter data, lake bed photography and sediment samples reveal a complex landform r...
