dc.description.abstract | Delineation of capture zones for groundwater source protection is normally performed by using numerical codes which are based
on the porous medium flow equation. However, boreholes are often sited in or along permeable dykes or single fracture zones
through which aquifers are drained. It is very important to take into account dyke-influenced aquifers. This paper makes use of
Linesink to simulate permeable dyke or fractured zones and utilises the pathline distribution to delineate the capture zones.
Conditions when the influence of a fractured dyke can be considered negligible are also discussed through comparison with
stagnation point in a uniform flow field. The approach may be sufficient to illustrate protection zoning requirements when dyke
aquifers are considered. | en_US |
