<br /> <br />Standard Project Flood <br />The flood that may be expected from the most severe <br />combination of meteorological and hydrological conditions that are <br />considered reasonably characteristics of the geographIcal area in <br />which the drainage basin Is located, excluding extremely rare <br />combinations. PG4kdlschargas for these floods are generally about <br />40 percent to 60 percent of the Probable ~ximum Floods for the <br />same basins. Such floods, as used by the Corps of Englneors, are <br />intended as practicable expressions of the degree of protection <br />that should be sought in the design of flood control works, the <br />failure of whiCh might be disastrous. <br /> <br />, <br />. <br />, <br />, <br />I <br />I <br />, <br /> <br />Top of Waterway <br />This Is the roof of the opening In a stream crossing <br />through which water flows under nor"", I conditions.
