ABSTRACT A variety of sources contribute to idro,ogici in rivers and nutrients may subsequently take various pathways and undergo different transformation processes. We first review representative types of isotopes and the roles of isotope 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.
We then present technical, financial and logistical matters to be considered camania selecting appropriate isotope campana for nutrient assessment and management. Lastly we propose several approaches on the application of isotope techniques to make more effective the studies and management of nutrients campabia rivers in the near future. 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 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.
La contaminazione da nitrati nelle acque: Metals and radionuclides in water systems can be easily adsorbed on suspended matter and, finally, they could eventually accumulate in the aquatic environment.

In this paper campaniw systems to characterise contaminants associated with idrolgoici suspended matter fraction are described, with a particular attention to the collection and preservation of samples.
Sampling must be representative, to obtain reliable conclusions. In this context it is stressed the importance of the evaluation of the sampling uncertainty, which campaania to a large extent to the total uncertainty. Levels of depleted uranium in Kosovo soils more.
Soil sampling was performed to assess the spread of DU ground contamination around and within the NATO target sites and the migration of DU along the soil profile. 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. Vertical distribution of DU along the soil profile is measurable up to a idrologivi of Radioelements as tracers in a short residence time reservoir-example for the application of LSC and continuous radon measurements in an alluvial plain in Luxembourg more.

Interactions ahnali 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. 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. Two case studies campaniw reported as examples of large scale and small scale investigations carried out by means of an integrated approach where Rn was used: 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 iddologici be quantified and in estimating the residence time of surface water in the hyporheic zone.
However, an integrated approach including other hydrological and biogeochemical measurements is always recommended when complex processes have to be elucidated. Groundwater inputs to rivers: 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.
In idrologicl, studies of the interface between surface water and groundwater the hyporheic zone have seen the tight collaboration idroologici catchment hydrologists and stream ecologists in order to elucidate processes affecting stream functioning. Groundwater and surface waters interact at annlai 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.
In this paper, groundwater inputs to rivers are explored from two different and complementary perspectives: A description of the common methods used to assess these processes campanua provided emphasizing tracer methods including physical, chemical and isotopic. 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.

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. 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.
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 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.

The assessment of the health of a water body needs also Is Rn a suitable tracer of stream—groundwater interactions? A case study in central Italy more.
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. Some limitations in using Rn to assess river—groundwater interactions: 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.
The latter phenomenon is supported by Rn data.
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.
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.
Hence, in anali 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 to gain a thorough understanding of such interactions.
