Modelling vadose zone flows and groundwater dynamics of alluvial aquifers in Eastern Gangetic Plains of India: evaluating the effects of agricultural intensification

The floristic exploration and critical examination of specimens collected of family Convolvulaceae from Upper Gangetic Plains of India, resulted in addition of 2 new records for the flora viz. Ipomoea littoralis and Ipomoea capitellata var. multilobata. Detailed description, phenology, ecology, distribution, locality, field number, type specimens examined, illustrations and other relevant notes are provided.

This paper is a survey of overall species counts from northern and central Hampshire sites, of Iron Age, Roman and early Saxon date, and their implications for chronological changes in animal husbandry and diet. Three zones, around Basingstoke, Andover, and central Hampshire, are compared with each other, and also with the Roman urban centres of Silchester and Winchester. The Andover region shows the greatest degree of continuity from Iron Age to Roman times and later, while the Basingstoke region has a pattern of change from sheep/goat dominated assemblages to ones with higher cattle numbers. This may be due to agricultural intensification, and an orientation of the animal economy in northern Hampshire more towards the Thames Valley and supply to Silchester, than an earlier 'Wessex pattern' more focussed on sheep and wool production.

Abstract Goczałkowice reservoir is one of the main source of drinking water for Upper Silesia Region. In reference to Water Frame Directive matter since 2010 the strategic research project: „Integrated system supporting management and protection of dammed reservoir (ZiZoZap)”, which is being conducted on Goczałkowice reservoir, has been pursued. In the framework of this project complex groundwater monitoring is carried on. One aspect is vadose zone research, conducted to obtain information about changes in chemical composition of infiltrating water and mass transport within this zone. Based on historical data and the structural model of direct catchment of Goczałkowice reservoir location of the vadose zone research site was selected. At the end of November 2012 specially designed lysimeter was installed with 10 MacroRhizon samplers at each lithological variation in unsaturated zone. This lysimeter, together with nested observation wells, located in the direct proximity, create the vadose zone research site which main aim is specifying the amount of nitrate transport in the vertical profile.
