#002 The Worlds Columbian Exposition Scrapbook, 573 9 B. The Terek Feeding-Canal. Referring to the above-mentioned feeding canals, I would propose to construct one from the river Terek, the beginning of which I would place below the confluence of the rivers Terek and Malka. I would like to mention here that, scientifically speaking, the Terek and its basin, containing a much smaller quantity of water than the Malka, should be considered as an affluent of this latter, and not as geographers state that the Malka is a tributary of the Terek. The elevation of the Terek, at the proposed opening of the canal is 530.74 feet, above the level of the Black Sea. The highest point of the Manytch lowlands above the Black Sea is 81 feet*). Consequently we have a difference of 449-74 feet, which, in 326.40 versts, the total length fo the canal, would give an inclination of 1.38 feet in the verst, or more than 0.0003. This gradient being too considerable we are bound to reduce it to O.0002 by making 48 falls. In the case of the Jumna- Ganges Canal in India an incline of 0.0003 w38 at first allowed, but it was afterwrards found necessary to reduce it by the making of falls. As a general rule we must calculate the speed of current for irrigating and feeding canals at not more than 4 feet per second. From the Terek I propose to take 13.1 cubic sajens per second at low water, and 21.2 cubic sajens per second at high water- this can easily be done, as the quantity of water carried down by the Terek is from 18 to 57 cubic sajens per second, and the fall of the river, below the town of Mozdok, is not less than o.0009**). I also propose to build, close to the village of Tchernoyarskaya, a vast basin for collecting the heavy sediments, for instance sand, as otherwise the canal could become obstructed. The passing of the water through this basin would not prevent the lighter river mud or slime from being carried on into the canal. The utility, for agricultural purposes, of this mud or slime, is obvious to all. The dimensions of this feeding canal are as follows: a) The Terek-Kama Section, for Irrigation only. Length 162.5 versts. Transversal section: Width at bottom 126 feet. Depth, at low water 9 " " at high water 12 Incline 0.0002 Number of falls, 0.75 saj. high 48 Volume of water per second, min. 13.10 cub. saj. " " " max. 21.20 " " *) According to the calculations made by the Kumo-Manytch Expedition. **) Levelling investigations made by Mr. Petersen C. E. and Mr. Dahl, C. E.
