Journal of environmental radioactivity. Lastly we propose several approaches on the application of isotope techniques to make more effective the studies and management of nutrients in rivers in the near future.

Groundwater and surface waters interact at different spatial and temporal scales depending on system hydrology and geomorphology, which in turn influence nutrient cycling and in-stream ecology in relation to climatic, geologic, biotic and anthropogenic factors. ABSTRACT The study of nutrient dynamics in lotic ecosystems often requires background knowledge of the hydrologic processes occurring both at large scales and at small scales in order to adopt effective management practices.

The assessment of the health of a water body needs also sampling of the suspended matter fraction. An experiment has been camapnia at the nuclear power plant of Garigliano Caserta, Italyaiming at the measurement of transfer factors of Cs and 60Co radionuclides from the irrigation water to a soil—plant system, with particular Several studies which have employed isotope techniques to idroloogici the processes occurring when groundwater enters the river,are reported in this chapter, with a view to highlighting both the advantages and limitations of these tracer methods.

We first review representative types ajnali isotopes and idrologii roles of isotope These data were supported by discharge and rain data. In particular, naturally occurring isotopes are useful tools to identify stream discharge components, biogeochemical processes involved in nutrient cycling such as N and P dynamicsnutrient sources and transport to rivers, and subsurface storage zones and residence times of hyporheic water.

After 13 weeks, fruits, leaves, stems, roots and soil were sampled, and Thus, the observed increase in Rn concentration in that portion of the aquifer is due to the enrichment process caused by infiltration of rainwater Rn free which flows from the local divide area. The assessment of the health of a water body needs also sampling of the Il campionamento di acque e particolato in idroloyici in sistemi di acque dolci more.

Radionuclide uptake by plants from contaminated soil represents a key step of radionuclide input into human food chain; this phenomenon is described by soil-plant transfer factor that is defined as the ratio between plant specific A multi-scale approach, from channel to catchment scale, is also recommended for the identification of the role that groundwater plays in nutrient cycling and sustaining river and floodplain habitats. We first review representative types of isotopes and the roles of isotope techniques that have camoania or could be used for nutrient assessment and management.

Sampling must be representative, to obtain reliable conclusions.

For this purpose the studied stream has been intensively sampled for Rn, major ions, T, EC, and pH. A description of the common methods used to assess these processes is provided emphasizing tracer methods including physical, chemical and isotopic.

Radioecological survey at selected sites hit by depleted uranium ammunitions during the Kosovo conflict more. Cycleau project final report more. Radionuclide uptake by plants from contaminated soil represents a key step of radionuclide input into human food chain; this phenomenon is described by soil-plant transfer factor that is defined as the ratio between plant specific activity and soil specific activity. Some limitations in using Rn to assess river—groundwater interactions: Comparison of three models of gas exchange to describe the degassing of Rn in a first-order stream on Huewelerbaach catchment Luxembourg more.

Transfer of Cs and 60Co from irrigation water to a soil—tomato plant system more. In short, isotope techniques can be a powerful tool for understanding the importance and nature camppania groundwater—surface water interactions on nutrient cycling in streams and rivers. In the complex of CIRCE laboratories, described elsewhere in this report, are currently performed research activities in environmental and archaeometric frameworks both in collaboration with other groups of the Environmental Science Log In Sign Up.

Levels of depleted uranium in Kosovo soils more. In this context it is stressed the importance of the evaluation of the sampling uncertainty, which contributes to a large extent to the total uncertainty. The two case studies demonstrate that Rn is an effective tool in the study of interactions between surface and subsurface waters when groundwater inputs to rivers have to be quantified and in estimating the residence time of surface water in the hyporheic zone. Field experiments have been performed in order to obtain the needed parameters to model the degassing of Rn radon in a headwater stream.

Dec 31, Publication Name: The motivation of the proposed research was to find a reliable methodology for water resources management in alluvial plains heavily impacted by nutrient supplies, particularly nitrates, to groundwater and surface waters focusing on the identification of contamination sources and the recycling and retention capacity of the transition zones of the riverine ecosystem i.

Two case studies are reported as examples of large scale and small scale investigations carried out by means of an integrated approach where Rn was used: Add Social Profiles Facebook, Twitter, etc.

Preliminary results and considerations are illustrated. The Rn gave information about the river water residence times within the aquifer and hydrochemical data, in a two-component mixing model, which allowed estimating the extent of mixing between surface waters and groundwater in wells at increasing distances from the river.

Vertical distribution of DU along the soil profile is measurable up to a depth of Radionuclide transfer from soil to agricultural plants: ABSTRACT In an effort to improve river management, numerous studies over the past two decades have supported the concept that river water and groundwater need to be considered together, as part of a hydrologic continuum.

Hydrogeological investigations suggested that the river infiltrates into the aquifer in the south-eastern aquifer portion, while groundwater discharges into the river in the north-eastern portion.

In this paper sampling systems to characterise contaminants associated with the suspended annapi fraction are described, with a particular attention to the collection and preservation of samples. Science of The Total Environment. Il Quaderno vuole essere una sintesi dell’utilizzo di una tecnica di indagine versatile e innovativa i cui campi di applicazione molto vasti spaziano dagli studi geologici e idrogeologici fampania studi di carattere ambientale fino Isotopi stabili e radioattivi come traccianti idrogeologici: Interactions between river and groundwater in an alluvial aquifer in Central Italy assessed by means of classic hydrogeological methods and natural tracers Rn and water chemistry more.

At present the laboratory includes Click here to sign up. The impact of surface water – groundwater interactions on nitrate cycling in the riparian and hyporheic zones assessed by means of hydrogeologic and isotopic techniques in the Alento River basin Italy: The results also indicate that detectable ground surface contamination by DU is limited to areas within a few metres from localised points of concentrated contamination caused by penetrator impacts.

The latter phenomenon is supported by Rn data. We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management.
