This paper analyses the value of flood warning information and most reliable media for disseminating early warning in rural communities of Nepal with a case of the West Rapti River Basin. Five focus group discussions and 240 household interviews were conducted to assess the preferred early warning techniques and communication medium. A siren/alarm system was ranked the most preferred technique. The sound produced from this system can easily be heard by a large mass of people at varying locations within a short time. Flood early warning information from the right place, on the right time, to the right people provides in advance the notice of flood occurrence which helps to reduce casualties and damages.
