The contribution to the sample mean plot, originally proposed by Sinclair (1993), is revived and further developed as practical tool for global sensitivity analysis. The potentials of this simple and versatile graphical tool are discussed. Beyond the qualitative assessment provided by this approach, a statistical test is proposed for sensitivity analysis. A case study that simulates the transpo...

A BEM numerical model is presented for the flow and solute transport in fractured porous media, which is based on the dual reciprocity method multi domain scheme (DRM-MD). The model solves the 3D flow equation based on the Darcy law in the coupled system of porous media, fracture network and fracture intersections. Unlike the discrete fracture models, which for simplicity use Fick's law in the ...

Construction of underground research laboratories and geological disposal facilities has a significant transient impact on groundwater flow, leading to a drawdown in the water table and groundwater pressures, and groundwater inflow into shafts, access ways and tunnels accompanied by desaturation of the surrounding rock. Modelling the impact of underground facilities on groundwater flow is impor...

LIFE+ project “Strategies to improve and protect soil quality from the disposal of olive oil mills’ wastes (OOMW) in the Mediterranean-PROSODOL” aims towards the development and application of technologies for the protection, improvement and remediation of soils which are polluted from the disposal of olive oil mill's wastes. In this effort, several geospatial application tools were presented a...

The Waste Isolation Pilot Plant (WIPP) has been developed by the U.S. Department of Energy for the geologic (deep underground) disposal of transuranic waste. Compliance with the containment requirements is demonstrated by means of performance assessment (PA). The term PA signifies an analysis that 1) identifies the features, processes and events (FEPs) that might affect the disposal system; 2) ...

C around the world are researching, developing and demonstrating disposal of long-lived radioactive waste in engineered repositories located in suitable deep underground geological formations as the reference solution to protect present and future generations and the environment. In some countries, actual implementation of geological disposal projects is only a few years away. Countries are als...

In the United States an estimated 140,000 Class II wells for salt water disposal and enhanced hydrocarbon recovery are presently injecting some 30 million barrels of brine per day into subsurface formations. While no systematic survey has documented the extent of shallow ground water contamination from these disposal practices, it is recognized as a major potential pollution source in leading h...

The thermo-hydraulic-mechanical behaviour of a large in situ heating test, the Buffer/Container Experiment (BCE), carried out at Atomic Energy of Canada’s underground research laboratory, is considered. The work can be seen as an extension of the authors’ previous research, investigating the behaviour of a large-scale test, the socalled ‘isothermal test’, to now include heating effects. Suggest...

The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...
