Short summary
This paper presents a study on short-term ensemble flood forecasting for small dam catchments in Japan. Numerical ensemble simulations of rainfall from the Japan Meteorological Agency nonhydrostatic model are used as the input data to a rainfall–runoff model for predicting river discharge into a dam. Overall results are considered on some level helpful for decision-making related to flood control, especially as a supporting tool in addition to discharge observations and radar rainfalls.
