Application of the probability matrix method to the Labugama & Kalatuwawa reservoirs

Abstract

The research considers the application probability Matrix Method to Labugama and of the Kalatuwawa reservoirs and storage-draft-probability of failure relationships have been derived. The study shows that preliminary design procedures using the Mass Curve Method/Residual Mass Curve Method also give useful results which can be used in the Probability Matrix Method. The Probability Matrix Method requires a relatively large computational effort. It has been observed that for satisfactory results a large number of zones are needed in the analysis without which the hunting effect arises.
