| Abstract | The fate and transport of Cryptosporidium parvum oocysts affecting groundwater involves processes at the surface and in the subsurface which are impacted by hydrological events and human and animal activities. In these coupled systems, numerical modelling is crucial to assess how oocysts deposited at the surface may influence the quality of groundwater. Describing the oocysts as microbial colloidal particles, we can obtain travel paths and the viability of oocysts using a random walk particle tracking (RWPT) method in a coupled flow system. The coupled flow system consists of overland flow and flow in variably saturated media. The interaction between two media is handled through coupling fluxes. For the given hydraulic and oocyst conditions, rapid oocyst transport into groundwater is observed, and oocysts traced remain viable for a long period in the aquifer. |
