Tigris–Euphrates river system border. Since the 1960s and in the 1970s, when Turkey began the GAP project in earnest, water disputes have regularly occurred in addition to the associated dam's effects on the environment. In addition, Syrian and Iranian dam construction has also contributed to political tension within the basin, particularly during drought. The general climate of the region is subtropical, hot and arid. At the northern end of the Persian Gulf is the vast floodplain of the Euphrates, Tigris, and Karun Rivers, featuring huge permanent lakes, marshes, and forest. The aquatic vegetation includes reeds, rushes, and papyrus, which support numerous species. Areas
Water flow test Water flow test A water flow test is a way to measure the water supply available at a building site, usually for the purposes of installing a water based fire protection system (fire sprinkler system). The most common test involves measuring the flow of water flowing out of a municipal fire hydrant (measured in gallons per minute) while recording how much the water pressure has dropped (from no water flow to test flow). When the results are collected carefully, formulas can be applied to figure the varying pressure(s) that will be available when different amounts of water flow are used
