Abstract
The flash flood warning process typically includes monitoring, forecasting and warning dissemination components. With current systems, there are many opportunities for improvements throughout this chain, particularly in the accuracy of observations and forecasts and the efficiency of warning procedures. This chapter highlights a number of recent developments in these areas, including phased array weather radars, wireless sensor networks, adaptive sensing techniques and the provision of warnings to road users. This includes a discussion of some of the challenges in translating research ideas into operational practice and the role that hydrometeorological testbeds can play in this process. Some current research themes in rainfall and flood forecasting are also described which are of particular interest for flash flood applications, including the communication of probabilistic information to end users.
