PREFACE

Due to rapid economic growth in recent years, the demands of water for additional agriculture, industry and public water supplies in Taiwan have increased drastically each year. In compliance with the "Comprehensive Development Pro-grams for Taiwan", the entire area of Taiwan is divided into north, central, south and east water resources regions. Each region is considered as an integral unit to provide optimum economic utilization of water resources through effective control and distribution in commensurate with the social and economic requirements.

Hydrological data is the basic requirement for water resources management and development. Hydrometric stations on the river basins in Taiwan have been successively established by agencies concerned in the past years. In collaboration with the Commission, Taiwan Hydrometeorological Network has been set up for years. The ways of observation and recording are standardized through the network. Therefore, the Commission, after proper processing, published the data collected from the primary hydrometric stations from the very beginning of each station.

The first volume of "Hydrological Year Book of Taiwan", covering the data collected from the beginning of each station up to 1970, was published in 1972. The Year Books of 1971 through 1985 were also published annually. Compilations of these publications have been improved gradually. This volume for 1986 will be distributed to various agencies. It might be expected that the government agencies as well as the private interested could make practically use of this publication. Any suggestions for improvement of the Year Book would be appreciated.
