Use of Geomorphological Land Classification Maps in Technical Assistance to Developing Countries

Abstract

The usefulness of geomorphological maps for determining areas subject to flooding is recognized both in Japan and in developing countries, especially those in Southeast Asia that have much rain with resultant flooding. At the request of ECAFE, the author prepared such maps for Vientiane, Laos, and for Nongkhai, Thailand, and vicinity. Also, at the request of JICA, the author prepared a map for the Padang area of West Sumatra in Indonesia, and with assistance from the National Research Institute for Earth Science and from the Disaster Prevention Science and Technology Agency, he and others prepared a similar map for the Central Blain of Thailand.
