Abstract
Bofedales, seasonally saturated peat-forming wetlands, are recharged by groundwater draining from uplands and store and regulate water resources important to downstream communities across the seasonally dry puna grasslands of Perú. Bofedales form in interior basins where rainfall and surface topography cause a positive water balance that leads to seasonally saturated conditions. However, little is known about the subsurface structure linking contributing hillslope aquifers to bofedales. We combine geophysical methods, long-term hydrological monitoring, and a rock physics model to characterize the hydrogeologic connection between the hillslope aquifer and bofedales in the Upper Ramuschaka Watershed, a headwater catchment within the Vilcanota Urubamba Basin of Cusco, Perú. Over 2.8 km of seismic data reveal a thick weathered zone (> 30 m) below hillslopes and a thin weathered zone (0 to 20 m) below bofedales. We present a watershed-scale conceptual model that highlights the zone of hydrologic connectivity between the hillslope and bofedal. This insight into the subsurface can inform sustainable bofedal management in the puna, contributing to local and regional water security.
