Dykes, or levees, are structures designed and constructed to keep the water in a river within certain bounds event of flood. In relation with climate change, more frequent floods, higher intensity, can be expected due anthropogenic emissions greenhouse gases into atmosphere. The objective this review paper is address many ways which geosynthetics contribute sustainable construction dykes thus s...

If a class of nitely generated groups G is closed under isometric amalgamations along free subgroups, then every G 2 G can be quasi-isometrically embedded in a group Ĝ 2 G that has no proper subgroups of nite index. Every compact, connected, non-positively curved space X admits an isometric embedding into a compact, connected, non-positively curved space X such that X has no non-trivial nite-sh...

mineral paragenesis of rodingitized basic rocks of iranian ophiolites are presented and metasomatic reactions between ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. it is concluded that ca+2 rich aqueous fluid in equilibrium with serpentinite has high ca+2 chem...

Injected sandstones occurring in the Kimmeridgian of NE Scotland along the bounding Great Glen and Helmsdale faults formed when basinal fluids moved upward along the fault zones, fluidizing Oxfordian sands encountered at shallow depth and injecting them into overlying Kimmeridgian strata. The orientation of dykes, in addition to coeval faults and fractures, was controlled by a stress state rela...

In the upper Subansiri District of Arunachal Pradesh, India, Higher Himalayan Crystallines are exposed in and around Taliha and the outcrop of MCT in the immediate south of Taliha is recognizable with the development of tourmaline bearing leucogranite dykes representing melting of the crustal rocks. The gneisses of the Taliha area consist of mainly quartz, mica, K-feldspar and garnet. The Quart...
