The rapid growth on industrial and commercial development has greatly increased the demand for water. Through proper operation a water resources system achieve to satisfy various types of water demand. Due to the inherent hydrologic uncertainty and others, it is impossible and economically impractical to design a water resources project having a sufficient capacity for all demands. Therefore, to determine a reliable yield with an allowable shortage is a key issue for assessing in the performance of a water resources projects. Furthermore the issue on the tolerances for various projects, is contraversial and does not have an acceptable standard. Currently shortage index is a common technique used for the assessment.
The purpose of this study is to present a procedure on the availability evaluation a water resources of system. This procedure emphasizes on the statistical analyses of failure data, and is applied to the Kao-Ping & Tseng-Un River Basin Management System as an example. A comparison with the commonly used SI index, has shown that the proposed method is superior.
