For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

Introduction Fly ash, a by-product from power plants, is a powdery gray material that is stored in large ash dykes or ponds. This ash is used in making bricks and in cement factories. Fly ash is considered to be a major pollution problem as it is dispersed into the air and pollutes bodies of water. However, for the local tribal populations of Korba district, Chhattisgarh state, fly ash is becom...

Assessing and mapping damage risk of floods for large river basins is still in its infancy. Damage risk is understood to be the combination of flood hazard and the vulnerability of communities to a flood of a particular return period. Risk is calculated and mapped for two communities in which dykes are not located for flood protection: Meissen on the Elbe River and Döbeln in the Mulde catchment...

Previous studies have indicated that in patients with severe attacks of ulcerative colitis, changes occur in the levels of the serum proteins. These changes consist principally of a fall in the serum albumin level, and a rise in the level of the alpha 2 globulins (Bicks, Kirsner, and Palmer, 1959; Brooke, Dykes, and Walker 1961; Soergel and Ingelfinger, 1961). Furthermore attacks of ulcerative ...

post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...

metagabbro, metadiabase and metabasalt of the chah palang and me'raji mountains associated with lower paleozoic metamorphites are situated in the south of arousan. metabasites of these areas are relatively similar in terms of mineralogy and geochemical characteristics. rock-forming minerals of the me'raji metabasites are feldspar, amphibole, biotite, sphene, epidote, chlorite ± calcite. metagab...

The Kızıldağ (Hatay) ophiolite in southern Turkey represents a complete, although fault-dissected, remnant of oceanic lithosphere that formed within the South Tethyan ocean during late Cretaceous. forms part Upper Cretaceous belt which includes Troodos (Cyprus), Baer-Bassit (Syria), Amanos (S Tukey), S Iran and Semail (Oman) ophiolites. Ion-probe (SIMS) dating seven samples crustal rocks (cumul...

Introduction: Metadolerite dykes in the Western Dharwar Craton represent oldest generation of mafic dyke swarms craton. The emplacement these after a period crust building activity and komatiite volcanism, helps to understand evolution Subcontinental Lithospheric Mantle (SCLM) Archean dynamics. Methods: We report whole rock major, trace element geochemistry Sr-Nd isotope characteristics for thi...
