Field experiments can serve as a base for modelling or for verification and calibration of the model. Mathematical models enable smaller amount of measurements in a certain area by means of measurements carried out only in characteristic points. Field experiments are very often very time and physical work demanding, so they have to be planned carefully and complex enough to be of cost benefit for researches. Combination of on site measurements and mathematical modelling proved to be an efficient method for understanding of processes in nature.
F.10 Improvements to an existing technological process or technology
COBISS.SI-ID: 6061945The large wetland area with its numerous aquifers in the extreme south of the Ljubljana basin is a very important water resource with very complicated hydrological structure. Tritium and oxygen isotope composition were therefore determined, beside others parameters such as concentrations of gamma-ray emitters and geochemical parameters (Ca2+, Mg2+, Na+, K+, Cl-, SO42-, NO3-, HCO3. Conductivity, pH, H-2). Obtained results confirmed existance of many different types of groundwaters in the basin and clarify the status of lower aquifers.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 22950951In the lecture the results of the project ''Farming possibilities in water protection areas'' were presented. The project is being carried out in the area of Dravsko polje, which is at present the most heavily polluted aquifer in Slovenia. With regard to the WFD (European Water Framework Directive) it is possible that a good groundwater chemical status will not be achieved by 2015. Therefore the main objectives of the project are to realistically evaluate the degree of groundwater pollution resulting from agricultural activities, and to suggest such farming practices which will present a lesser pollution load on groundwater and at the same time maintain sufficient crop yields.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 1971541In the publication, Slovenian water resources protection system is presented. Groundwater has a prevailing share in the balance of Slovenia's water resources and in the public drinking water supply. The European Water Framework Directive (WFD) demands that the state establishes a good chemical and quantity status in all surface and ground water bodies. Three important intergranular aquifers are in the danger of not achieving the WFD demands by 2015. The current Rules on the criteria for the determination of groundwater protection areas determine four categories of water protection areas, introducing different degrees of problematic land use limitation. The article presents also supplementary measures contained in the draft of the Slovenian Water Management Plan, intended to establish a good quality status also in these heavily polluted aquifers.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 1950549The aim was a complex interpretation of Ljubljansko polje and Ljubljansko barje (LPLB) aquifers chemical status on the basis of the groundwater (GW) monitoring data. Hydrochemical data were merged and uniform time series of concentrations of individual relevant pollutants in the area of LPLB aquifers were obtained. Typical values for relevant chemical parameter were elaborated. Results enabled identification of problematic GW pollutants and delineation of most contaminated areas. Results form the basis for the implementation of groundwater remediation actions.
