The zero is: at Assuân R. L. 85·00 at Assiut „ 45·55 at Cairo „ 12·25 =N.B.=--At Assiut R. L. 45·55, according to the reservoir levels, is R. L. 45·05 according to the 4th Circle levels. (The discharges are in cubic metres per second.) This discharge table may be used approximately for any gauge on the Nile north of Assuân with its zero at mean low-water level; adding ·5 to the gauge in Kena Province, and deducting ·5 from the gauge in Minieh and Beni-Suef. If the river is rising, take the discharge corresponding to the higher gauge; if falling or stationary to the lower one. ======+========== Gauge.|Discharge. ------+---------- -1·0 | 360 - ·8 | 406 - ·6 | 452 - ·4 | 498 - ·2 | 544 ------+---------- 0·0 | 590 ·2 | 668 ·4 | 746 ·6 | 824 ·8 | 902 ------+---------- 1·0 | 980 ·2 | 1086 ·4 | 1192 ·6 | 1298 ·8 | 1404 ------+---------- 2·0 | 1510 ·2 | 1652 ·4 | 1794 ·6 | 1936 ·8 | 2078 ------+---------- 3·0 | 2220 ·2 | 2408 ·4 | 2596 ·6 | 2784 ·8 | 2972 ------+---------- 4·0 | 3160 ·2 | 3404 ·4 | 3648 ·6 | 3892 ·8 | 4136 ------+---------- 5·0 | 4380 ·2 | 4674 ·4 | 4968 ·6 | 5262 ·8 | 5556 ------+---------- 6·0 | 5850 ·2 | 6150 ·4 | 6450 ·6 | 6800 ·8 | 7200 ------+---------- 7·0 | 7600 ·2 | 8000 ·4 | 8400 ·6 | 8800 ·8 | 9300 ------+---------- 8·0 | 9800 ·2 | 10300 ·4 | 10900 ·6 | 11500 ·8 | 12100 ------+---------- 9·0 | 12800 ·2 | 13600 ======+========== TABLE XXXVIII.
