Fracture analysis of concrete gravity dam under earthquake induced loads
In this paper, seismic fracture behavior of the concrete gravity dam
using finite element (2D) theory has been studied. Bazant model which
is non-linear fracture mechanics criteria as a measure of growth and
smeared crack was chosen to develop profiles of the crack. Behavior of
stress - strain curves of concrete as a simplified two-line, dam and
reservoir system using the formulation of the Euler - Lagrange was
chosen. According to the above models, Koyna concrete gravity dam were
investigated by the 1967 earthquake record. The results provide
profiles of growth and expansion first with the effects of reservoir
and second without it. Comparison of the obtained results shows good
agreement with the works of the other researchers

Southern Caspian Sea Coasts, Morphology, Sediment Characteristics, and Sea Level Change
As the world\u27s largest closed body of water, considerable changes in the Caspian Sea water level make it an unique laboratory to study all aspects of coastal zones. This research was aimed at evaluating the linkage between sea level changes and sediment characteristics of the south Caspian Sea coast. Initially, three field surveys were made along 700 km of the southern Caspian Sea coast. In addition to nearshore sampling, land forms were mapped. On the basis of the field reconnaissance, eight principal sampling stations were chosen. Sediments were sampled by divers along profiles at right angles to the coast at 5 depths (2, 4, 6, 8,10 meters). Hydrographic profiles also were surveyed. Laboratory tests on the sediment samples were made, and the sediment characteristics and morphological features were divided into distinct zones based on their response to sea level changes
