Abstract

The National Hydraulics Laboratory which, in collaboration with the Saclay Nuclear Research Centre, has for several years been devising equipment and techniques for the study of sediment movements by the radioactive tracer method, is now endeavouring to develop a really quantitative method of research. Two river experiments were recently made, the first a study of shingle drifting in the Rhone, the second a study of sand movement in the Niger. The latter experiment was matched by identical experiments carried out on a scale model of the River Niger which the Chatou Laboratory has at its disposal. The experiments used Mn{sup 56} and Na{sup 24} radiation obtained by direct activation of crushed apricot stone, this representing in the scale model the natural sediment of the Niger bed. The Chatou Laboratory and the Saclay Nuclear Study Centre are at present both devoting attention to the application of radioactive tracers in studies with scale models, with the twin aims of: (a) Obtaining a single research tool for use under natural conditions and with scale models in order to gauge the trustworthiness of the model, in the calibration testing stage; (b) Taking advantage of the facilities for direct observation and measurement offered by scale  More>>

(author) [French] Le Laboratoire national d'hydraulique, qui depuis quelques annees a developpe, en collaboration avec le Centre d'etudes nucleaires de Saclay, les appareillages et les techniques d'etudes des mouvements de sediments par la methode des traceurs radioactifs, s'efforce actuellement de mettre au point un moyen d'investigation veritablement quantitatif. Deux experiences ont ete effectuees recemment en riviere, la premiere a ete consacree a l'etude du charriage des galets dans le Rhone, l'autre a l'etude des transports de sables dans le Niger. Cette derniere experience a ete doublee d'experiences identiques, effectuees sur le modele reduit du fleuve Niger exploite par le Laboratoire de Chatou. Dans ces experiences on utilise le rayonnement du {sup 66}Mn et du {sup 24}Na obtenu par activation directe du noyau d'abricot concasse representant sur le modele reduit le sediment naturel du lit du Niger. Les efforts conjugues du Laboratoire de Chatou et du Centre d'Etudes Nucleaires de Saclay portent actuellement sur l'application, des traceurs radioactifs aux etudes SOT modeles reduits, dans le double but: a) De disposer d'un meme moyen d'investigation en nature et sur modele reduit pour controler la fidelite du modele, dans la phase des essais d'etalonnage; b) De profiter des facilites d'observation et mesures directes offertes par les modeles reduits pour etudier les possibilites d'amelioration de la methode des traceurs, en particulier en ce qui concerne l'obtention de renseignements quantitatifs. (author) [Spanish] El Laboratorio Nacional de Hidraulica, que en colaboracion con el Centro de Estudios Nucleares de Saclay viene estudiando desde hace varios anos los aparatos y las tecnicas de observacion del movimiento de sedimentos mediante indicadores radiactivos, procura perfeccionar actualmente un procedimiento de investigacion que permita obtener resultados cuantitativos. Recientemente se han efectuado dos experimentos en otros tantos rios. El primero tuvo por objeto estudiar el arrastre de canto rodado en el Rodano, y el segimdo, el transporte en arenas en el Niger. Paralelamente con este ultimo experimento, se llevaron a cabo ensayos identicos en el modelo a escala reducida del rio Niger instalado en el Laboratorio de Chatou. En estos ensayos se utilizan las radiaciones del {sup 56}Mn y del {sup 24}Na, obtenidas por activacion directa de huesos de albaricoque triturados, que en el modelo representan el sedimento natural del lecho del rio Niger. Los esfuerzos conjugados del Laboratorio de Chatou y del de Saclay se centran actualmente en torno al estudio de la aplicacion de los indicadores radiactivos a los estudios sobre modelos a escala reducida con el doble proposito de: a) disponer de un procedimiento de investigacion comun para los estudios efectuados sobre el terreno y en los modelos a escala reducida, con el objeto de poder controlar la fidelidad del modelo durante los ensayos de calibracion; b) aprovechar las ventajas que ofrecen los modelos a escala reducida en cuanto a facilidad de observacion y mediciones directas, para estudiar las posibilidades de mejorar el metodo de los indicadores, especialmente en lo que se refiere a la obtencion de datos cuantitativos.

Za poslednee vremya bylo provedeno dva opyta v prirodnykh usloviyakh v rekakh; pervyj iz nikh byl posvyashchen izucheniyu uvlecheniya gal'ki vodami Rony, a drugoj - izucheniyu peremeshcheniya peska v reke Niger. Parallel'no s poslednim opytom byli provedeny identichnye ispytaniya na makete reki Niger, sozdannom v laboratorii v SHatu. V ehtikh opytakh bylo ispol'zovano izluchenie margantsa-56 i natriya-24, vyzvannoe neposredstvennoj aktivatsiej tolchenoj kostochki abrikosa, izobrazhavshej v ispytaniyakh na makete prirodnye donnye otlozheniya Nigera. Sovmestnye usiliya laboratorii v SHatu i TSentra yadernykh issledovanij v Sakle napravleny v nastoyashchee vremya na primenenie metoda radioaktivnykh indikatorov k opytam na maketakh s dvojnoj tsel'yu: a) Vyrabotat' odinakovye metody issledovaniya v prirodnykh usloviyakh i na makete dlya proverki tochnosti maketa v stadii opytov po ehtalonirovaniyu; b) Ispol'zovat' legkost' vedeniya nablyudenij i proizvodstva neposredstvennykh izmerenij na maketakh dlya izucheniya vozmozhnostej usovershenstvovaniya metoda radioaktivnykh indikatorov, v osobennosti dlya polucheniya kolichestvennykh dannykh.
