Yes, I am happy to collaborate with any potential users. There is a long history of CAESAR being take up by others including researchers in Italy, France, Spain, NZ, Australia, USA. +

CAESAR is a cellular landscape evolution model, with an emphasis on fluvial processes, including flow routing, multi grainsize sediment transport. It models morphological change in river catchments. +
