The <span>ancient civilization that relied primarily on underground rivers, springs, and lakes to support their cities</span> was Egypt. This is also as a result of the Nile river.
The answer is C) Egyptian. The Egyptians had good sources of water so it was natural for them to learn how to use them in the best way. The Nile river was the most useful source, but other lakes/rivers were also used. The Manzala Lake, being a saltwater lake, was practically useless other than for fishing. <span>Aswan (Nasser) Lake was located behind the Nile river and was used for farming. </span> These lakes/rivers were used for Irrigation, <span>canals, and fishing. Hope this helps!</span>
The Groins are hard structures and used to maintain uplift beaches as to restrict longshore sediment transportation form tasking place. Are meant to capture sand transportation by the currents.
While the jetty is another type of shore perpendicular structure that is placed adjacent to the tidal inlets and controls the inlet migration. Both of them are used to destabilize coastal systems and disrupt the natural sediment regimes.
