Abstract
This case deals with hydraulic and tracer migration tests at a synthetic site. A highly detailed, realistic but synthetic geosphere was developed whose geometry, processes and parameter ranges were conditioned with data from the Grimsel Rock Laboratory. A limited number of `experiments` on the synthetic geosphere in the form of transient and steady-state pumping tests were conducted by numerical simulation. The project teams were provided with qualitative and quantitative information from the simulated tests, and could request further data. Modelers calibrated their models with the available data, and were then asked to compute breakthrough of conservative tracer between boreholes using their calibrated models. Results were then compared to the `true` results calculated and supplied by the Pilot Team using the complete synthetic geosphere. The project teams used methods ranging from simple manual adjustment to sophisticated mathematical inverse and geostatistical procedures to estimate the parameters and in some cases predict break through. Result failed to indicate a clear advantage of more complicated methods of analysis over simpler ones. However, several of the teams using more sophisticated methods did not have adequate time to complete their analyses. This exercise demonstrated the great difficulty of predicting site performance on the basis of a
