1. füzet - Lougani, Hocine-Zsuffa István: Segédlet a dombvidéki tározók hidraulikai méretezéséhez
Segédlet a dombvidéki tározók hidraulikai méretezéséhez 99 резервуаров с простой геометией (рис. 5.) результаты расчетов приведены в таблице II. Путем дальнейшего упрашения расчета авторами предлагается использовать лишь одно соотношение, т.е. соотношение объема при 50% высоте наполнения к полниму объему резервуара (рис. б). В ходе расчета водосброса необходимо учитывать помимо гидравлических и топографических данных и гидрологические исходные данные (рис. 8). Для расчета аварийного сброса авторами предлагается семейство кривых, полученных по кривым расходов (В) широкопорогого водослива, зависимость (16). В случае узких долин скрутыми склонами необходимо учитывать, что быстроток проходит по склону дамбы. Для расчета данного неблагоприятного и опасного случая предлагается сложная номограмма (рис . 9). Manual for the hydraulic dimensioning of reservoirs in hilly areas by Hocine, LOUGANI C.E. and Dr. István ZSLJFFA C.E., candidate of technical sciences In order to speed up the pace of planning, and to secure its uniformity, a manual for hydrological and hydraulic dimensioning of reservoirs had been issued to support the national program of constructing small reservoirs in the hilly areas of Algeria. By aid of the above introduced manual (Groupes d'études, 1986) structures of reservoirs in hills, their pipe-sluices for water intake, the bottom-drain, their spillway emergency outless, chutes, and energy breaking basins can be determined. Dimensioning of water intakes is a simple hydraulic problem. The so-called Moody-diagrams (Fig. 1.) are for a direct determination of the discharges as functions of the pipe-diameter (£>), pipe-length (L), and pressure head (A) Fig. 2 is a presentetion of simplified procedure if a given or recommended dam cross-section was the basis of dimensioning. Fig. 3, however the product of the composite discharge-factor of the pipe (C w) and of its surface area (A c) is obtained as a function of relative length (L/D) of the pipe-sluice. While dimensioning the bottom-drain, the dimensions of the reservoirs basin and its geodetic parameters are to be taken into account beside other hydraulic information and relationships (Fig. 4.) Results obtained for reservoirs with simple geometry (Fig. 5) are summarized in Table I. For further simplification, the use of a single value-pair is recommended by the authors; the ratio of the volume belonging to half water stage, and of the total volume storable water (Fig. 6). In the dimensioning of spillways, hydrological information was predominant beside the hydraulic and topographical parameters (Fig. 8). If emergency outlets were designed the recommended procedure is to use the enclosed diagram containing a set of curves (Eq. 16) based on the rating curves derived from the discharge measurements of wide-threshold weirs. In case of extremely narrow and steep walled valleys, spillway-chutes must be constructed in the side-slopes of the earth-dam. In such exterme, unfavourable and dangerous cases a composite nomogram is recommended by the authors (Fig. 9).
