Rainwater Management at Al-Baha City by Using Time- Series Models in the Prediction of Precipitation Rates for the Period from 1985 to 2014 AD

Abstract

The aim of this research is to select the best from the among time series models available for the preparation of the proper rainwater management, by providing the necessary information to the competent authorities to be able to employ them optimally and to maximize the benefits from them; also to use the result predictions in improving the future rainfall management data, The outcome of the study is that there is significant humidity is there for the rainfall in following years and also there is no significant wind speed impact on rainfall so it has been excluded from the model; The Researcher recommended the adoption the result of this study and also recommends the adoption of this forecasting model by the relevant authorities for the approval of the appropriate scientific method to use in prediction of the rainfall.
