Il laboratorio comprende attualmente un sistema di spettrometria di massa con 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 campanix. Skip to main content. Hence, in the study site, the use of only Rn to predict river—groundwater interactions causes some estimation inaccuracies and it must be coupled with other hydrochemical and hydrogeological parameters wnnali gain a thorough understanding of such interactions.

We first review representative types of isotopes and the roles of isotope techniques that have been or could be used for nutrient assessment and management. Sampling must be representative, to obtain reliable conclusions. Interactions between river and groundwater in an alluvial aquifer in Central Italy assessed by means of classic hydrogeological idrllogici and natural tracers Rn and water chemistry more.

In the framework 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 Groundwater inputs to rivers: However, an integrated approach including other hydrological and biogeochemical measurements is always recommended when complex processes have to be elucidated.

Remember me on this computer. 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 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.

We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management.

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 xampania of a hydrologic continuum.

Radionuclide transfer from soil to agricultural plants: Metals and radionuclides in water systems can be easily adsorbed on suspended matter and, finally, they could eventually accumulate in the aquatic environment. In particular, the project aimed to test the noble gas The assessment of the health of anjali water body needs also sampling of the suspended matter fraction.

Field experiments have been performed in order to obtain the needed parameters to model the degassing of Rn radon in a headwater stream. Il campionamento di acque e particolato in sospensione in sistemi di acque dolci more. 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. In this paper, groundwater inputs to rivers are explored from two different and complementary perspectives: La contaminazione da nitrati nelle acque: Characterisation of a reference site for quantifying uncertainties related to soil sampling more.

ABSTRACT A variety of sources contribute to nutrients in annalii and nutrients may subsequently take various pathways and undergo different transformation processes. The main recommendations for their use are to keep well in mind the appropriate spatial and temporal scales of the chosen technique and to use them in conjunction with other methodologies in order to better test working hypotheses and conceptual models. A case study in central Italy more. Comparison of three models of gas exchange to describe the degassing of Rn in a first-order stream on Huewelerbaach catchment Luxembourg more.

In particular, naturally occurring isotopes are useful tools to identify stream discharge components, biogeochemical processes idrokogici in nutrient cycling such as N and P dynamicsnutrient sources and transport to rivers, and subsurface storage zones and residence times of hyporheic water.

Add Social Profiles Facebook, Annwli, etc. 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.

For this purpose the studied stream has been intensively sampled for Rn, major ions, T, EC, and pH. Help Center Find new research papers in: 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.

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.

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 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.

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. 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 In particular, studies of the interface between surface water and groundwater the hyporheic zone have seen the tight collaboration of catchment hydrologists and stream ecologists in order to elucidate processes affecting stream functioning.

Cycleau project final report more. 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.

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.
