Abstract
This report, Volume 9 of the 11-volume report on the master design simulator (MDS), describes the water generator subsystem. This subsystem simulates the flow of water through a typical watershed- reservoir combination to predict mine drainage quantities in underground workings. The model is an integrated one that handles both the unsaturated and the saturated flow domains as a unified system. The solution of the model is achieved by numerical techniques of finite difference method coupled with finite element analysis. The water generator can be operated either as a free- standing model or in connection with the geology and reserves subsystem as a part of the MDS. A case study is included illustrating the application of the model to actual data. The appendices constitute a user's manual and a program listing.
