MSc. Pedro Hervé

My research interests focus on quantifying how catchment hydrology and biogeochemical cycling (ecosystem services) are affected by different land covers, mainly driven by Pedroanthropic effects (i.e: tree farming). Among specific interests are the use of tracers like stable isotopes of water (2/1H and 18/16O) for the quantification of (1) catchment water balance (i.e evaporation of water from soils, groundwater recharge, and vegetation root water uptake); (2) hydrograph separation analysis; (3) source contribution of water vapour; (4) Mean residence time of water in a catchment. I also have some experience using other stable (i.e: 13/12C and 15/14N) and radioactive (i.e: 7Be, 134Cs, 137Cs and 210Pb) isotope tracers for a better quantification of ecosystem scale processes (i.e: carbon sequestration and nitrogen use efficiency) and erosive processes at catchment or ecosystem scale.

  • Ecohydrological differences between native and fast growing exotic plantations This research is mainly focused on tracing water pathways and sources during storms and understanding its movement through catchments with different vegetation land cover such as in pristine native evergreen forest and fast growing exotic plantations (Eucalyptus nitens) in Chile, using stable isotopes of water (D and 18O) and water chemistry.

Project ends: April 2016.
