The Construction of Dams The earliest remains of dams that archaeologists have discovered date back to approximately 5000 A.D.They were assembled as a member of a national water supply system for the ancient city of Jawa in Jordan. Over the next few millennia, the building of dams for water retention spread across the Mediterranean, the Middle East, Southern Asia, China, and Central America. Afterwards, as technology enhanced and industrialization took hold in Europe, dam mechanisms advanced to incorporate watermills. With the introduction of the water turbine in 1832 and improvements in electrical engineering, the first hydropower plant began running in Wisconsin in 1882 (IRN n. pag.) . Over the next few decades, while structural technology techniques enhanced, dams multiplied in size, strength, and numbers worldwide. Now, although the construction of new dams is stopping ( albeit with less energy in underdeveloped countries) (p Villiers 146; Pielou 206), now they're still being assembled around the world for a great number of social and economic reasons: flood control, hydroelectric power generation, river navigation, and irrigation, individual consumption, industrial usage, emergency water reservation, tourism, and flat-water diversion (e.g., NPDP n. pag.; Trout Unlimited 11). For all of the benefits that dams provide, however, there are adverse results and concerns that arise out of manipulating the surroundings in this unnatural method. Impacts of Dams on the Hydrologic Regime Dams are ultimately generated as a water reservoir. This impounding of water hastens the circulation of a river and then changes the hydrology and ecology of the river network and its own neighboring environments. Beneath a dam, the rise in water level submerges the l.. .
