The hydrological role of wetlands in mountain environments are poorly understood, yet as glaciers recede, lakes and wetlands (including peatlands) will become more widespread, altering flow regimes and influencing baseflow and low flows. Wetlands have considerable assets from an ecosystem services perspective; they mitigate downstream effects of extreme precipitation in mountain environments through water retention and reduced flow velocity and also provide water back to ecosystems during periods of drought. Wetlands provide critical wildlife habitat, improve water quality through natural filtration, and are a viable cost alternative to built infrastructure such as levees and bypasses. The overall goals of this project are to establish the ecohydrological function of alpine wetlands, how this function varies among wetland types across an elevation gradient, and to assess their overall hydrological role in the changing mountain environment.
