After the great flood in the year 2011, KAS Thailand together with Nakonsawan Provincial Administration, governmental operation units, and private sectors has analysed and researched about the courses, organised many seminars and dialogues to exchange ideas among experts in order to reduce the damage from the flood which may happen in the future. This publication therefore aims to disseminate the geographical knowledge and hydrology of the province, flood-risky areas as well as the flood management strategy to both governmental and public sectors.
