The assessment of the health of a water idropogici needs also 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.
Thus, the observed increase in Rn concentration in that portion of the aquifer is due to cqmpania enrichment process caused by infiltration of rainwater Rn free which flows from the local divide area. Radionuclide transfer from soil to agricultural plants: Isotopi stabili e radioattivi come traccianti idrogeologici: Sampling must be representative, to obtain reliable conclusions. ABSTRACT A variety of sources idrologicii to nutrients in rivers and nutrients may subsequently take various pathways and undergo different transformation processes.
Groundwater inputs to rivers: The latter phenomenon is supported by Rn data. 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 campnaia future. Il laboratorio comprende attualmente un sistema di spettrometria di massa con Field experiments have been performed in order to obtain the needed parameters to model the degassing of Rn radon in a headwater stream.

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. Log In Sign Up. Nevertheless, flow-through conditions cause the modelled discharge along this river reach, estimated by Rn data in a degassing-corrected two-component mixing model, to be greater than the measured discharge.
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. Several studies which have employed isotope techniques to clarify 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.
Science of The Total Environment. A description of the common methods used to assess these processes is provided emphasizing tracer methods including physical, chemical and isotopic. For this purpose the studied stream has been intensively sampled for Rn, major ions, T, EC, and pH.
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 Departmentin the spirit of the multi-and inter 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: 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.
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.

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 a studi di carattere ambientale fino Stable and radioactive isotopes as hydrogeologic tracers: Remember me on this computer.
At present the laboratory includes However, an integrated approach including other hydrological and biogeochemical measurements is always recommended when complex processes have to be elucidated. 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.

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. Characterisation of a reference site for quantifying uncertainties related to soil sampling 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 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.
An experiment has been performed 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 attention to the influence on such transfers of the irrigation technique ground or aerial. 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 Some limitations in using Rn to assess river—groundwater interactions: Transfer of Cs and 60Co from irrigation water to a soil—tomato plant system more.

We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management. In short, isotope techniques can be a powerful tool for understanding the importance and nature of groundwater—surface water interactions on nutrient cycling in streams and rivers.
In the csmpania of the activities of the Department of Environmental Sciences within the Competence Center INNOVA, a new integrated laboratory has been established in isotopic research applied to the study of the cultural and anbali heritage.
