Abstract

The aim of this chapter is to analyze the effect of the groundwater flow in free-surface hydrodynamics. Several series of turbulent flow measurements were carried out in a re-circulating flume where upward seepage was induced by external hydrostatic pressures acting in the lowest part of the channel bed. The results of the experimental measurements (namely, the mean velocities, statistical moments, and other turbulence parameters for established hydrodynamic conditions) are presented and analyzed. The differences between the open-channel hydrodynamics with and without seepage are compared. The upward seepage influenced the behavior of velocity fluctuations. Consequently, some of the turbulence parameters were affected, such as the turbulent kinetic energy and the Reynolds stresses.
