Page 195 - CONCLUDING REMARKS. In the preceding pages an attempt has been made to give some idea of the various questions which must, in the near future, engage the attention of those responsible for the control of the Nile. Before bringing this Report to a conclusion, it may be as well to express an opinion regarding the degree of urgency involved in the separate schemes therein set forth. Moreover, in all projects connected with Nile regulation the interests of Egyyt are so closely linked with those of the...
Page 140 - ... on either side of her. During the stormy season, it should if possible always be arranged that two steamers should work in conjunction, one remaining down-stream, so as to be able to go to the assistance of the other if necessary. As no fuel is to be met with throughout the whole length of the sudd...
Page 119 - Bahr-alGabal has an evil name for mosquitoes, and one that is well deserved. With the disappearance of the sun they come forth in countless myriads, and make life a burden until the luminary reappears above the horizon. The whole region has an aspect of desolation beyond the power of words to describe. It must be seen to be understood.
Page 6 - Assouan Reservoir. The great weakness of this projected lake has lain in the fact that by itself it can give a plentiful discharge in April and May, less in June, and very little in July, and it was for...
Page 59 - This region is very similar in its character to that lying to the south of Fort Portal, being a high tableland broken by ranges of low hills, which rise above swampy valleys and stretch to the north and east as far as the eye can see. Few of 'these hills are of any height, and most of them are of rounded outline. The general level rises gradually from the east to the west, ie, to the edge of the escarpment.
Page 168 - ... apparently, upon any actual discharges measured during a maximum flood. The first waters of the Atbra appear to reach the Nile with great regularity during the last week of June, and by the middle of July the discharge, according to the measurements of the last two years, is from 300 to 400 metres cube per second, increasing to double this amount by the end of the month. The rise in August is very rapid, and the maximum is usually reached between the last week of August and the first 10 days...
Page 9 - General of Irrigation in Egypt, stated as his opinion, that in any calculations for the size of the Nile flood escape channel, the minimum discharge to be allowed for, should be 100,000,000 metres cube per diem. Such a discharge would necessitate a canal of very large section. Any such work would involve a very heavy expenditure, which would only be warranted, were no other means of providing for the escape of the flood water possible. Other means do exist, and this brings me to the third and last...
Page 172 - The best way in which to secure the results aimed at would appear to be to reserve the waters of the Blue Nile for the improvement of the countries bordering that river, while Egypt and the area of the Nile Valley lying to the north of Khartoum shall derive their siunmer supply from the sister river.
Page 198 - ... should not be sure. What has once been may again be, and there are good grounds for anticipating an eventual return to prosperity a prosperity, perhaps, even greater than that which excited the astonishment of Nero's envoys nearly nineteen centuries ago. Those to whom the privilege shall be granted of assisting towards this consummation will have a chance given to them such as seldom falls to the lot of man. To rescue the Upper Nile from the marshes in which it has lost more than half its...
Page 20 - ... 1904. fol. Pp. 20). The object of this study was to collect existing data as to the changes of level of the lake, and to endeavour to trace from these data the oscillations of the lake during the last twenty or thirty years. Two rainy and two dry seasons make up the year in the Victoria Lake basin, the rains coinciding more or less with the equinoxes, and the dry seasons with the solstices, except that the second, or minor, rains are delayed one or two months after the autumn equinox. The rainfall...
