Kolja Rotzoll

Biography

Kolja Rotzoll is a hydrologist with a focus on combining coastal processes and hydrology. His expertise is in:

  • numerical groundwater-flow and transport modeling of island aquifers (SUTRA, SEAWAT, MODFLOW with SWI2)
  • soil-water balance modeling to estimate spatially distributed recharge (SWB2)
  • time-series analysis of coastal groundwater levels to estimate hydraulic properties, impacts of sea-level rise, and other hydrological processes in Hawai‘i and Guam
  • script-based approach to model-file generation, data analysis, and presentation (Python, MATLAB)
