AbstractAbstract
[en] The processes of bank filtration were investigated in the course of a six-year interdisciplinary research project of the DFG in the 'Boeckinger Wiesen' drinking water reservoir near Heilbronn. A material and pollutant balance was established for the overall system, with particular regard to the transport in the unsaturated zone, which is located in a 3-5 m layer of meadow loam. Below this, there is a 4-5 m gravel layer which forms the primary aquifer. The deeper body of groundwater is located in solid triassic rock which is highly jointed and partly karstified. The meadow loams were analyzed with regard to their soil-physical characteristics. The soil water conditions of the unsaturated zone were determined in a number of neutron probe measuring points. The observations suggest a capillary sealing effect in the lower part of the loam layer. Groundwater regeneration was quantified in long-term measurements and was integrated in the hydrological balance of the overall system. (orig.). 9 figs

Im Trinkwassergewinnungsgebiet 'Boeckinger Wiesen' bei Heilbronn wurden waehrend eines 6-jaehrigen interdisziplinaeren DFG-Forschungsvorhabens die Vorgaenge bei der Uferfiltration untersucht. Im Rahmen der vorliegenden Arbeit wurde die Stoff- und Schadstoffbilanzierung des Gesamtsystems durchgefuehrt. Besondere Beachtung fand dabei der Eintrag ueber die ungesaettigte Zone, die in einer 3 bis 5 m maechtigen Auelehmschicht ausgebildet ist. Darunter befindet sich eine 4-5 m maechtige Kiesschicht, die den Hauptgrundwasserleiter bildet. Das tiefere Grundwasserstockwerk liegt in zerkluefteten und teilweise verkarsteten triassischen Festgesteinen. Die Auelehme wurden eingehend auf ihre bodenphysikalischen Eigenschaften untersucht. Der Bodenwasserhaushalt der ungesaettigten Zone wurde in mehreren Neutronensonden-Messstellen erfasst. Die Beobachtungen weisen auf das Auftreten eines Kapillarsperreneffektes im unteren Bereich der Lehmschicht hin. Die Grundwasserneubildung wurde in langjaehrigen Messungen quantifiziert und in die hydrologische Bilanzierung des Gesamtsystems integriert. (orig.)Original Title

AbstractAbstract
[en] This invention has to do with a procedure and device for the simultaneous radiometric determination of quantity, quality and foreign substances in moved bulk materials in particular lignite at one measuring point. The section of the bulk material discharge is transmitted by nuclides for soft and hard gamma radiation in pairs. The pulse rates are registered in pairs by means of detectors and evaluated in real-time operation

AbstractAbstract
[en] The invention has been aimed at eliminating or, at least, reducing the influence of density on radiometric determinations of the content of pressed samples, e.g. in determining the ash content of lignite. This can be achieved by recording the changes in density during pressing and stopping the process after reaching a given density value

AbstractAbstract
[en] The invention has been aimed at a procedure and equipment for a radiometric assay of the content of bulk materials moved by conveyor belts. In particular it can be used for quantity and ash content determinations of lignite discharges by means of a radiometric conveyor-type weigher and ash content meter. The average radiometric mass attenuation coefficients of hard and soft gamma irradiation of the lignite-multisubstance mixture have been determined for low and high ash contents by ultimate analysis. A radiometric mass attenuation coefficient correlation has been formed and used for control and correction of the measured values of the conveyor-type weigher and ash content meter
