Abstract The compound labyrinth weir is a new type of that considered good applicable choice for increasing the capacity discharge. flow over complex problem because behavior three-dimensional. present study aims to simulate into critical regions cannot be observed when using an experimental test. computational fluid dynamics (CFD) programme was utilised implement sensitive analysis this purpos...

The Paramirim Aulacogen was filled by the Espinhaço and São Francisco supergroups in period from 1.75 to 0.69 Ga, suffered partial inversion during Ediacaran. In northern sector of intracontinental domain Araçuaí-WestCongo Orogen, six compressive deformational phases were interpreted associated with frontal Aulacogen. Three structural domains identified: Jacaraci Fold-Thrust Belt, Caetité Nappe...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

The area between the villages of Reka in Idrijca Valley, Bukovo and Zakriž near Cerkno belongs geographically geotectonically to Dinarides. consists two large inner thrust blocks Trnovo nappe, which were thrusted for tens kilometers direction SW their present position. They are overlain by Tolmin lowest unit Southern Alps. nappe was from N S a smaller intermediate sheet. In western part contact...

Les agriculteurs utilisant les eaux des khettaras, galeries souterraines drainant la nappe phréatique et donnant un accès collectif à l’eau souterraine dans oasis, font aujourd’hui face dilemme. khettaras se tarissent sous l’effet conjugué du pompage pour potable de l’irrigation exploitations agricoles nouvelles extensions, d’une recharge décroissante nappe. Leurs menacées disparition, certains...
