Research Questions

For predicting reactive transport in the environment, many scientific models concepts compete with each other. The existence of competing models adds an additional level of uncertainty to any endeavor of system understanding or prediction. Among the competing models, more accurate models are typically more complex. This implies that, unless they are fed with more data for calibration, their predictions are affected by more uncertainty.

To address this problem, we will investigate:



The envisaged methods in project P8 are:

All these methods rely heavily on scientific understanding of the involved catchment, model building, numerical simulation, computational statistics and mathematical optimization.
