Project: Experimental Characterization of Instream-Hyporheic Fluxes in Vegetated Channels and Wetlands

Acronym: HYPOVEG
Main Objective: The project will provide a conceptual model for the hydrodynamics of exchange processes between the hyporheic region and the surface in vegetated areas. As the findings of the project will eventually mature into simulation tools that will positively impact river (bio)engineering practices, the immediate innovations pertains essentially to fluid mechanics and to instrumentation, comprising:
- a new database of flows within and over the bed of idealized vegetated streams;
- a Navier-Stokes solver based on Lagrangian SPH discretization, applicable to open-channel flows and flows within multiply connected domains (porous media and vegetated regions);
- a new time-resolved PIV and LIF instrumentation will be developed, remaining available, once the project is terminated, to Portuguese and international research groups.
The innovative aspect of the instrumentation must be highlighted: the time-resolved PIV-LIF system is a sophisticated measuring device that will create the conditions for major advances in realm of fluid mechanics and mass transport with applications to environmental problems.
