Three sites M1 (tide pole site in the centre of Chwaka Bay), M2 (at the entrance to the mangrove creek) and X1 (in the mangrove creek)An echo-sounder measured depth along east-west transects in the bay and in the mangrove creek on the south-western side.

For training purposes, the model was also applied to Tudor Creek, Mombasa, Kenya (but no field data are available for this).
