Prediction of floods in ungauged basins

This chapter focuses on the prediction of floods in ungauged catchments. In the context of this book flood prediction is defined as the estimation of flood runoff and the associated exceedance probability at an unknown future point in time, as opposed to real-time flood forecasting where forecasts are made for the immediate future. The focus is on river floods induced by heavy rain, sometimes in association with snow melt, but dam breach floods, ice jam floods, and floods due to other processes are not dealt with in this chapter.
