Characteristics and behavior of the flow in hydraulic structures, a complex phenomenon that isimperative to use software that will beto be study.Gabiony stepped spillway is a simple hydraulicstructures to control erosion downstream of dams, and, depreciation of structures is used. Roughstairway consisting of overflow from the stairs near the crest of the weir is started and continues tohave a l...

A new method of evaluation of the response of a water table to artificial recharge is presented. The solution is formulated in the form of a simple numerical model. The model has several advantages over the traditional methods of mounding prediction. The effect of the unsaturated zone, which modifies the recharge rate as compared with the infiltration rate, is considered. Mounding is calculated...

The Aefjord-Sitas area (approximately 68*15'N;16*45'E) includes three of the principal tectonic elements of the northern Scandinavian Caledonides: a) a nappe complex, representing the main Caledonian allochthon and consisting of metasedimentary and metaigneous rock sequences that are probably in part of oceanic provenance; b) the Rombak window, a fenster through the nappe complex revealing Balt...

New Ar-Ar muscovite and Rb-Sr biotite age data in combination with structural analyses from the Apuseni Mountains provide new constraints on the timing and kinematics of deformation during the Cretaceous. Time-temperature paths from the structurally highest basement nappe of the Apuseni Mountains in combination with sedimentary data indicate exhumation and a position close to the surface after ...

Chemical maps of garnet are the key to understand the tectonometamorphic evolution of the metamorphic rocks. They provide useful information on element distribution, diffusion, and mechanical truncation of crystal. In the Himalayas, studies on ultra-high pressure rocks denudated along the Main Central Thrust (MCT) revealed the great displacement along this intracontinental shear zone. Pêcher (1...
