Discharge Sediment and Power Generation Interaction Case Study Roseires Dam

Abstract

The prevailing problem of Rosaries Dam Reservoir is the sedimentation problem which endangered its operation performance. Rosaries Dam Reservoir is suffering from downstream river bank erosion, with problems in power generation. The objective of this study is to assess the relations among discharge sediment, and power generation. The researcher conducted dimensional analysis using Buckingham pi theorem and SPSS models, for both simple and multiple correlation. The software name of SPSS originally stood for Statistical Package for the Social Sciences. The simple correlation gave acceptable results with high correlation coefficients. Complete set of dimensionless groups were obtained using the rules of dimensionless analysis and theory of models in the multiple regression correlation. The results obtained clearly defined the interationship among the variable groups in a single equation. To reveal the interrelationship among discharge, sediment, generated power and irrigated areas, each dimensionless variable was put as independent variable on the left hand side of the equation and the other three on the right hand side to reveal the interaction and the degree of dependence. Examination of the results indicated good correlation with acceptable error.
