The geochemical characteristics of sediments deposited within a channel-type reservoir situated behind the weir of a water mill on the River Liswarta (southern Poland) were studied in relation to land use in the catchment. The catchment in question is an agricultural one with large forest areas. The contamination of sediments with trace elements was assessed using the geoaccumulation index. The...

The occurrence and abundance of darwinulid ostracods, as well as environmental factors influencing these patterns, were investigated in the alluvial valley of the upper Paraná River. Ostracods were sampled from several substrates, like littoral sediments and pleuston, which included several aquatic macrophytes species, from 31 localities (lentic and lotic) belonging to different riverine system...

The surfaces of alluvial fans and river deltas (collectively fans) are often dissected by a small number of channels radiating from the fan apex. On long timescales, channels migrate via avulsion, the process of channel bed deposition and abandonment that often results in catastrophic flooding and loss of life on densely populated fans. We present results of an experimental fan that creates rea...

This paper discusses conceptual elements and preliminary results of a workflow assessing habitat distribution and quality by means of object-based image analysis in a riparian forest. This follows the design of a ‘site-level’ service within the EC GMES project MS.MONINA to support the implementation of the Habitat Directive in Europe by providing dedicated EO-based services. We developed routin...

Investigation of the climatic and environmental impacts of the Youngest Toba Tuff (YTT, ∼74 ka BP) eruption of Toba volcano, Sumatra, is crucial for understanding the consequences of the eruption for contemporaneous human populations. The Middle Son Valley, in India, was the first locality on the Indian subcontinent where the YTT was reported. The ash bed forms a discontinuous layer stretching ...

This investigation was carried out at the Madeira River basin, located in the state of Rondônia, Brazilian Amazon. Fish from Madeira, Jaciparaná, and Jamari rivers between 7 and 11° parallels south and between 62 and 65° meridians west in Rondônia state, Brazil, were sampled and chemically analyzed for mercury in order to evaluate if the inputs of this metal into the food-chain is occurring in ...

The article is based on a long-term study of floodplain soils the Amur River valley within north-eastern part Middle-Amur Lowland. results field work soil-geomorphological profile across Slavyansky Island, located 200 km from Khabarovsk down River, are discussed. analyzes occurrence island's riolkas [1] and their properties, with an emphasis morphology lithological particle-size composition. fe...

In recent decades, China has been experiencing rapid economic development, population growth and urbanization. These processes have stressed the shortages of water resources in China, especially in the arid regions of northwestern China. In order to sustain the expanding cropland, people increased groundwater exploitation in these regions. The purpose of this study was to quantitatively analyze...

Changes in surface land use may threaten groundwater quality and ecosystem integrity, particularly in shallow aquifers where links between groundwater and surface activities are most intimate. In this study we examine the response of groundwater ecosystem to agricultural land uses in the shallow alluvial aquifer of the Gwydir River valley, New South Wales, Australia. We compared groundwater qua...
