Analysis of Inflow Time Series for Haditha Dam using Minitab Program

The optimal exploitation of water from a dam reservoir requires a comprehensive knowledge of future availability of water resources. In this paper Haditha dam selected (is located on the Euphrates River, the provider of a modern city with 7 km, with an initial storage capacity of 8,28 billion cubic meters). An annual series of inflow discharge records are used for twenty one year from (1991 to 2011) with two month (January and Feb.), in this paper estimating a linear trend function and generate the random series of inflow discharge by using classical decomposition of the series. The Minitab program as used in the procedures of time series analyzing. The data and results were explained in tables and graphs.
