Dr. Thom Bogaard

Thom Bogaard obtained his MSc degree in 1993 at the Vrije Universiteit Amsterdam studying surface erosion on terraced agricultural fields and sediment transport in small catchment in central-Java, Indonesia. Additionally he worked on micrometeorological research in relation to the desertification in central Spain. His PhD degree followed in 2001 at Utrecht University on the ‘Analysis of hydrological processes in unstable clayey slopes’. In 2007 he moved to Delft University of Technology department of Water management with main focus on experimental and hillslope/landslide hydrology. He also is affiliated with IHE Institute for Water Education.

Thom’s main research interest can be summarized as the interaction between water and environmental processes and their impacts on human society. Hereto, Thom focuses on hillslope and landslide hydrology as well as on development and application of innovative measurement techniques for hydrology. His main research topics are:

  • Hydrology: Hillslope and catchment hydrology, isotope hydrology, tracer application in water resources
  • Innovative monitoring in hydrology: Applying Fibre Optic Cable for distributed temperature and pressure measurements in hydrological systems; WaterTagging - developing nanoparticles with DNA-tag that can be used as water flow path tracer
  • Landslide hydrology: Hydrology and slope stability, reactivations and feedback mechanisms, vegetation & slope stability
  • Natural hazard and risk management and communication: regional hazard assessment
  • Hydrological and water quality observations and monitoring networks, citizen science
  • Capacity building: Myanmar, Vietnam, Rwanda, Ecuador
