Water quality dynamics in low-order watersheds: identifying and understanding the impacts of environmental change

Session ID#: 82509

Session Description:
Freshwater systems are under increasing pressure due to unprecedented environmental change (e.g. climate, land-use and management) and increased societal demand for water. Headwaters are particularly important as they control the flux of water, heat, sediments, nutrients and other solutes to larger downstream river systems and ultimately into the marine environment. Thus, understanding the drivers and impacts of change on water quality dynamics in headwater catchments is essential to better inform policy and management. With this in mind, it is becoming increasing clear that long term monitoring needs to be coupled with high frequency in-situ techniques to identify inter- annual/decadal trends and also short term responses to extremes. We invite contributions from all freshwater environments (pristine to human modified), and on long- term studies as well as high frequency studies exploring episodic responses to events. Also, we welcome contributions outlining novel technologies and analytical tools
