The mangrove formations of Godavari estuary are due to silting over many centuries. The estuary covers an area of 62,000 ha of which dense Coringa mangrove forest spread in 6,600 ha. Satellite sensor data was used to detect change in the mangrove cover for a period of 12 years (1992-2004). It was found that an area of about 1,250 ha of mangroves was destroyed by anthropogenic interference like ...

SUMMARYDuring excavations undertaken for the Dover Western Dock Revival Scheme, Kent, UK, Archaeology South-East (ASE; UCL Institute of Archaeology) encountered substantial remains associated with development port Dover. Despite natural limitations, especially in form silting from River Dour and longshore drift, has historically been a strategic location which to maintain port. The presented he...

a total of 3528 specimens of freshwater turtles belonging to two families viz., geoemydidae (brown river turtle, kachuga smithi; indian saw-backed turtle, k. tecta; brahminy rrive turtle, hardella thurgi; spotted pond turtle, geoclemys hamiltonii) and trionychidae (indian soft-shell turtle, aspederates gangeticus; peacock soft-shell turtle, a.hurum; narrow-headed soft-shell turtle, chitra indic...

Groundwater containing high amounts of products pyrite weathering as a consequence lignite mining flows into receiving waters for number years. Iron hydroxides causing turbidity and silting will strongly affect the river Spree many decades. In addition to liming acidic surface conventional treating mine waters, microbial sulphate reduction inflowing anoxic AMD groundwater is tested long-term re...

The use of the segmental pipe section immersed tunnel suffers from several problems, such as complex construction, weak foundation, great water depth, thickness siltation back on top tube, and difficult settlement control. Based Winkel’s elastic foundation beam theory, a mechanical calculation model is established according to case an inhomogeneous soil layer, force deformation structural syste...

Abstract Gentle algebras are in bijection with admissible dissections of marked oriented surfaces. In this paper, we further study the properties and show that silting objects for gentle given by associated surface. We associate to each algebra a line field on corresponding surface prove derived equivalence class is completely determined homotopy up homeomorphism Then, based winding numbers Arf...
