Having systematically reviewed a comprehensive range of management measures across a wide range of rivers this chapter provides an overview of lessons learned to inform future management strategies. Key lessons are elucidated that relates to (i) urban flood management, (ii) the role of floodplain sedimentology in the design of effective hydraulic infrastructure (iii), the unintended geomorphic consequences of hydraulic engineering (iv), the palimpsest of floodplain management (v), dam removal and reservoir management and (vi), linkages between geodiversity and biodiversity. These lessons pertain to three main fluvial environments, including fluvial adjustment of channels, embanked floodplains, and flood basins and deltas. The study concludes by discussing reasons for concern and reasons for optimism as regards future management of lowland river environments.
