Water Balance Approach to Prediction of Seepage From Mine Tailings Impoundments, Part II: Theoretical Aspects of Water Balance Approach to Seepage Modeling and Detailed Case History Results
Some of the most significant volumes and rates of interstitial tailings water discharge generally occurs during the initial portions of the primary consolidation process. During primary...
Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...
Grout Penetrability
The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are...
Cement Grouting: Water Minimising Practices
Water gives cement grout its mobility, but the water needed for mobility exceeds hydration requirements substantially in most applications. If this excess water is allowed to collect and...
Some Aspects of Analysis and Prediction of Subsidence
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions...

Successive Application of Reservoir Simulation Models--A Case Study
Replacement of the conventional method of generating hydrology by a well established reservoir simulation model renders enormous amounts of flexibility and savings in computation time....
Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....
Legal Constraints on the Transport of Water
Legal constraints on water transport are based on legitimate concerns for protecting the future interests of the area of origin, but such constraints sometimes appear overly restrictive...
