Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -To gain a better understanding the sedimentological behaviour in the estuarine, coastal environment and their distribution patterns in trace elements in the estuary and to examine variations in associated sediment uxes, 20 surface samples were collected throughout the Manakudy estuary, a minor Pazhayar river in south-western India. These samples, collected in typical dry season during Premonsoon 2012, were analyzed for Sedimentological, Textural and Trace Elements (HOAc). Our results show that estuary is dominated by sand fraction of the sediments (72.68%), the conservative behavior of trace metals with salinity has been strongly has been affected by the introduction of these metals by external sources and they are due to the higher organic activity in soils as well as faster rates of chemical weathering reaction in the source region. Even though the trace metals in the contaminated sediments have been removed and incorporated in sediments due to flocculation, the concentration of these metals did not decrease. The present study provides a history of accumulation of trace metals and their present level, and the data can be used as a baseline to monitor the estuaries environments. 76 pp. Englisch.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The transport of trace metals from the land to ocean has a number of different routes and efficiencies. The sources of toxic elements into the rivers to be debouched into the sea through estuaries are either weathered naturally from the soils and rocks or introduced anthropogenically from point or non-point sources, in labile form or in particulate form. However, recent studies indicate that the transport of trace elements to the aquatic environment is much more complex than what has been thought. The chemistry and ecology of an estuarine system are entirely different from the fluvial as well as the marine system. Estuarine environment is characterized by a constantly changing mixture of salt and freshwater. In the present study area Manakudy estuary is situated about 8 kilometres north west of Kanyakumari (Latitude N 08° 05 21.8 and Longitude E 077° 29 03.7 ). To gain a better understanding of the geochemical behavior of physico-chemical parameters and trace elements in the estuary and to examine variations in associated chemical uxes, 20 water samples were collected throughout the Manakudy estuary, a minor river in south-western India.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Geo-environmental terrain assessments and territorial zoning are useful tools for the formulation and implementation of environmental management issues (including policy-making, planning, and enforcement of statutory regulations). They usually involve a set of procedures and techniques for delimitation, characterization and classification of terrain units. However, terrain assessments and zoning exercises are often costly and time-consuming, particularly when encompassing large areas. Bhavani basin (Study area) is the fourth largest (about 6,500 km2) sub-basin in the Cauvery basin (81,000 km2). The western part (Western Ghats) is hilly terrain with an altitude ranging from 300 to 2,400 metres. The northern and north-eastern (Eastern Ghats), the southern and south-eastern sides of the basin are dominated by rugged discontinuous hills, with altitudes ranging from 300 to 1,000 metres. LANDSAT ETM+ data is one of the best River Basin models that can be used for understanding the geology, geomorphology, hydrology as well as agricultural productivity. It is also proved that the model can be employed under different climate change as well as management scenarios for developing adaptation. 96 pp. Englisch.…
