Since the main source of water recharge to these aquifers is from surface waters (e.g. Lake Chad), the aquifer system is highly sensitive to climatic changes. • ...The boundaries of an aquifer are usually gradational into other aquifers, so that an aquifer can be part of an aquifer system. The top of an unconfined aquifer is the water table. A confined aquifer has at least one aquitard at its top and, if it is stacked with others, an aquitard at its base.
