Christoph Jan KUELLS "The eco-hydrological perspective of desert restoration"

  1. 1. The Eco-hydrologicalPerspective on DesertRestorationWG 2 EU COST Action ES1104, Desert Restoration HubC. Kuells, S. Berkovicz, E. Constantini, C. Ritsema,V. Geissen, J. Hooke, I. Stavi, O. Yildiz
  2. 2. The Desert Restoration HubWorking group on soil and hydrologyThe role of ecohydrologyin Desert Restoration - RealmsWorking group ‚soils andhydrology‘ for the DesertRestoration Hub - TopicsParticipation and outreachFrom practice to science to practice –Cooperation 11.04.2013 2
  3. 3. Study SitesFocus on Europe – open to desert hydrology world-wide
  4. 4. Ecohydrology in DrylandsFrom concept models to process realms
  5. 5. Realms of Ecohydrology4 terrestrial zones Soil water ecohydrology The role of carbon in soil hydrology ‚enable WCM‘ Biochar – production and potential use in drylands Hillslope hydrology Are hillslopes the key to unlocking dryland‘s potential? Yair & Lavee 1974; Garvelmann et al. 2012 Ephemeral rivers in drylands Water availability from in drylands ephemeral rivers – functioning and role. Abdulrazzak & Morel-Seytoux 1983; Külls et al. 1994; Dahan et al. 2008 Groundwater ecohydrology in drylands
  6. 6. 4 Realms of EcohydrologyInterfaces: springs, rivers, wetlands, coasts The 4 realms of dryland ecohydrology form a system of redistribution and storage Their interfaces are important system boundaries for D balances of water and matter Disciplinary dissection
  7. 7. Groundwater Recharge of a Desert SoilRecharge at Mafraq/Jordan Zagana et al. 2007: Hydrol. Proc. 21: 2112-2123
  8. 8. Soils as Biogeochemical ReactorsResponse depends on system state Zagana et al. 2007: Hydrol. Proc. 21: 2112-2123
  9. 9. Realms of EcohydrologyHillslopes, topo-sequences, hillflow Soil water ecohydrology The role of carbon in soil hydrology ‚enable WCM‘ Biochar – production and potential use in drylands Hillslope hydrology Are hillslopes the key to unlocking dryland‘s potential? Yair & Lavee 1974; Garvelmann et al. 2012 Ephemeral rivers in drylands Water availability from in drylands ephemeral rivers – functioning and role. Abdulrazzak & Morel-Seytoux 1983; Külls et al. 1994; Dahan et al. 2008 Groundwater ecohydrology in drylands
  10. 10. Hillslopes in DrylandsAccumulators and concentrators Case study Namibia How does Welwitschia Mirabilis survive in a hyper-arid desert? Fog, groundwater, pla nt physiology or hillslopes
  11. 11. Hillslopes in DrylandsNew methods for unveiling soil water flow
  12. 12. Hillslope HydrologySnapshot of the hydrology of the past 1-100 years
  13. 13. Hillslope HydrologySpatial variability of vertical and lateral flows Hillslopes • Concentrate water at the surface and at the subsurface • Create a variety of eco-hydro-logical conditions • Are key structural components of dryland basins Garvelmann et al. 2012: HESS 16: 631-649
  14. 14. Realms of EcohydrologyEphemeral rivers Soil water ecohydrology The role of carbon in soil hydrology ‚enable WCM‘ Biochar – production and potential use in drylands Hillslope hydrology Are hillslopes the key to unlocking dryland‘s potential? Yair & Lavee 1974; Garvelmann et al. 2012 Ephemeral rivers in drylands Water availability from in drylands ephemeral rivers – functioning and role. Abdulrazzak & Morel-Seytoux 1983; Külls et al. 1994; Dahan et al. 2008 Groundwater ecohydrology in drylands

  16. 16. Ephemeral Rivers in DrylandsRole for desert ecohydrology and as water source Ephemeral rivers Concentrate runoff Abdulrazzak & Morel- Seytoux 1983 Are important landscape elements for groundwater recharge Külls et al. 1994 But how do they function? Dahan et al. 2008: Ground Water, 46(3): 450-469
  17. 17. 4 Months after Installation… data revealed functioning of recharge process 70 years of debate about groundwater recharge from ephemeral rivers in arid regions Models, hypotheses and assumptions First direct measurement of groundwater recharge process in arid zone
  18. 18. Ephemeral RiversFloods – vadose zone response - recharge Dahan et al. 2008: Ground Water, 46(3): 450-469
  19. 19. Realms of EcohydrologyGroundwater systems Soil water ecohydrology The role of carbon in soil hydrology ‚enable WCM‘ Biochar – production and potential use in drylands Hillslope hydrology Are hillslopes the key to unlocking dryland‘s potential? Yair & Lavee 1974; Garvelmann et al. 2012 Ephemeral rivers in drylands Water availability from in drylands ephemeral rivers – functioning and role. Abdulrazzak & Morel-Seytoux 1983; Külls et al. 1994; Dahan et al. 2008 Groundwater ecohydrology in drylands The black matter of the desert eco-hydrology universe
  20. 20. Groundwater in DrylandsJordan GREM project Zagana et al. 2007: Hydrol. Proc. 21: 2112-2123
  21. 21. Groundwater in DrylandsDirect recharge (soil realm)… Zagana et al. 2007: Hydrol. Proc. 21: 2112-2123
