Hydrological zoning (or simply zoning) is an approach to divide land into different zones based on their hydrological properties. Typically, each type of zone has different land use and development regulations linked to it. This land and water management method aims to protect local water sources from risks of over-abstraction, land salinization, groundwater pollution and waterlogging by managing land use activities based on the assigned hydrological zones. For example, zones with a high groundwater table, large amounts of surface water (e.g.

This research was aimed at assessing the accuracy of indigenous knowledge data on groundwater fluctuations when compared to scientific measurements in order to ascertain if it can be used for practical groundwater management. The study was done at three sites in ward 28 of Zaka district in Zimbabwe. The results at all sites were taken to show that the correlations between estimated groundwater levels from indigenous knowledge and actual recorded levels had correlation coefficients between 0.755 and 0.991 that were statistically significant.
