abstract:Tou-Chien Creek is located in Hsin-Chu County and has two tributaries, namely, Shang-Ping Creek and Yu-Lo Creek. The Shang-Ping Creek originates from the Hsueh Mountain, and the Yu-Lo Creek originates from the Li-Tung Mountain. The area of the Tou-Chien Creek watershed is 566 km<sup>2</sup> and the averaged annual rainfall is 2239 mm. The total runoff volume in a wet year is around 623 × 10<sup>6</sup> m<sup>3</sup> and is around 366 × 10<sup>6</sup> m<sup>3</sup> in a dry year. The target of the reservoir is for agriculture and public water supply. There are two weirs, namely, Chao-Shu-Pai and En-Lung, for dividing the stream flow. The Pao-Shan reservoir and the second Pao-Shan reservoir are the only storage facilities in this area. Recently, water demand in the Hsin-Chu Scientific Park is increase; therefore, the water distribution for agriculture and industry is a serious problem during drought. The objective of this study is to analyze the available water during drought in the Tou-Chien Creek basin. Since conventional drought flow analyses were based on stochastic approaches, the most up today rainfall information cannot be put into the model simulations. Therefore, a deterministic approach will be conducted in this study to simulate drought flow from aquifer under different return period conditions. The analytical results of this study can be used as a reference for water distribution in the Tou-Chien Creek basin during drought.
