PREFACE

With rapid economic growth in recent years, the demands for additional agricultural, industrial and public water supplies in Taiwan increase drastically each year. In compliance with comprehensive development program for Taiwan, the Commission is dividing the island into seven water resources regions, each as an integral unit to provide optimum economic use of the water resources by coordinated control and distribution in commensurate with social and economic development.

Hydrologic data is the basic information for water resources management and development. However, the existing hydrologic stations on the rivers in Taiwan were established by various agencies for different purposes and their measuring methods are diversive. The Commission, therefore, has collected from 72 main hydrologic stations on the major rivers the original records covering the period from the establishment of the said stations to 1970. With reference to hydrological year books of other foreign countries, these data were analyzed and consolidated into “Hydrological Year Book of Taiwan, 1970” last year. The year book is not only supplemented with new hydrological data up to the end of 1971, but also compiled with data of surface water quality and published as “Hydrological Year Book of Taiwan,1971” as references for agencies related to water resources planning and development.
