Theme 5: New Hydrological Theory - Wednesday, October 24, 2012
Convener: Murugesu Sivapalan (sivapala@illinois.edu)
Co-Conveners: Hessel Winsemius, Alexander Gelfan (hessel.winsemius@deltares.nl; hydrowpi@aqua.laser.ru)

The IAHS PUB decade has seen much activity and many advances in process understanding, methods of predictions, and assessment of the predictive methods. Have the explosion of new knowledge and the methodological advances led to a unified theory of hydrology at the catchment scale compared to before PUB was launched? Theory here is seen as more than the sum total of all knowledge, but as distilled knowledge, and as knowledge that is causally interlinked, i.e., every piece of knowledge makes sense with regard to all other pieces. Theory helps to connect the specific to the general, the local to the global, and the past to the future. Theory provides a framework to assess what we know and what we do not know. Theory provides avenues to seek the knowledge that we do not possess. This session is aimed at soliciting and debating potential new ideas that could contribute to a unifying framework that connects the various advances in knowledge and understanding gained over the PUB Decade towards a coherent new theory of hydrology at the catchment scale and in this way advance our ability to make predictions in ungauged basins and under change.
