EFFECT OF THE AERATION ZONE ON THE HYDRAULICS OF SUBSURFACE DRAINS FOR INFILTRATION WATER INTAKES
The aeration zone forms in the course of the infiltration intake operation as a result of basin floor clogging due to silt build-up. This zone was found to have a noticeable contribution to the hydraulics of the infiltration water intake. The aeration zone effect was investigated on a modified infiltration water intake model. The model included the contribution of the silt build–up phenomenon. The investigations have revealed that – compared to the influence of other contributing factors – the contribution of the degree of silting-up is dominant, and so is the influence of the aeration zone.
