The 4th International Multidisciplinary Conference on Hydrology and Ecology: Emerging Patterns, Breakthroughs and Challenges is to be held in Rennes, France from 13th - 16th May, 2013. The abstract submission deadline is September 30, 2012. The proposed sessions are:

S1: Interactions between surface water, hyporheic zone, saturated and unsaturated groundwater
S2: Plant-, surface- and or groundwater interactions
S3: Hydroecology in the wetland context
S4: River temperature: understanding physical processes and ecological impacts
S5: Pollutant buffering capacities from riparian zones to landscape
S6: Impact and role of extreme hydro-meteorological events on interactions between hydrological and biological processes
S7: Modelling interactions between hydrological and biological processes
S8: Scaling spatio temporal laws in Water, Life, and Landscapes
S9: Relevance and limitation of existing legal and regulatory legislation to maintain and enhance hydrological and biological interactions
S10: Restoration of hydrosystems services
S11: Hydroecological tools for assessment of aquatic ecosystems functions
