THE SPACIAL DISTRIBUTION OF GROUNDWATER DISCHARGE INTO THE LITTORAL ZONE OF A NEW ZEALAND LAKE

When off-line recharge trenches are used for the artificial recharge of unconfined aquifers the intake rates often decrease due to the deposition of a sediment layer on the surface of the recharge profile. The build-up of the impeding layer causes progressive hydraulic charges in the profile. The significance of these changes in relation to the intake rule depends on whether air is able to enter the pores of the saturated porous materials beneath the trench when the air entry value of the material is exceeded. Flow rates are calculated for recharge through a profile of #17 sand for conditions of "no air access" and "adequate air access". /Author/
