This session welcomes abstracts that consider how to measure, model and analyse interactions of people and water, and the effects of human and environmental changes on hydrological systems. It is organised as part of the IAHS Panta Rhei hydrological decade 2013-2022; and focuses on gains in our understanding of human-influenced hydrological systems during the second biennium of Panta Rhei 2015-2017.

All scientists working in the areas of hydrology, society and change are invited to submit abstracts. Examples of relevant areas include:

- Hydrological models that include anthropogenic effects
- Measurements of human impacts on hydrological processes
- Interactions of communities with local water resources
- Creation of databases describing hydrology in human-impacted systems
- Data analysis and comparisons of hydrological systems around the globe and especially in developing and emerging countries
- Human interactions with hydrological extremes of flood, drought and water scarcity.

This session will include an invited presentation by Lieke Melsen of Wageningen University, on including anthropogenic effects in hydrological modelling in the context of Philosophy of Science.
