RESEARCH OVERVIEW

To establish the medium to long term impacts of land management on hydrological processes at the catchment scale.

My research interests focus around the core theme of catchment management, particularly monitoring the impacts of land management on hydrological processes. I am currently undertaking a range of research projects examining the impacts of upland management and restoration on water quality and quantity in peat catchments, including impacts on storm discharge, erosion, sediment loads and DOC and POC export.
