Full textHydrogeological research in fractured crystalline rocks, often considered as being impervious, has been particularly advanced in recent years, in relation with feasibility studies for disposal of waste. This dissertation describes the practice of hydrochemical and isotope hydrology methods in such studies. The first part is a theoretical and bibliographical approach to the use of the isotope contents in aqueous sulphur compounds and of chlorine-36 as natural tracers. The second part presents two site studies: the Stripa mine in Central Sweden (Stripa Project) and the deep boreholes of the Swiss National Cooperative for the Storage of Radioactive Waste (NAGRA) in the crystalline basement of Northern Switzerland. From hydrochemical and isotope data, two water types can be distinguished in the aquifer system of the Stripa granite. Shallow waters, with low mineralization, are recent recharged. Their origin can be attributed to local precipitations. The deep groundwaters, with higher mineralization, may have resulted from a mixing between a relatively modern water mass (meteoric waters recharged at a higher elevation than the Stripa area) and an old brine of sedimentary origin, trapped in Precambrian rocks. The NAGRA boreholes tap waters circulating in the crystalline basement and in overlying sedimentary formations. Hydrochemistry and isotope hydrology show the relationship between these two kinds of waters and demonstrate the contribution of Permian salts or brines to the high salinity of some of the waters collected in the crystalline rocks. In conclusion, the third part of the dissertation critically examines the use of the various hydrochemical and isotope tracers trying to emphasize their contribution to the knowledge of crystalline rock hydrology

Full textRemote sensing, geomorphology, and hydrogeochemistry methods were used to characterize the ground water flow in this part of the Sassandra River watershed that lies in the Southwest of Ivory Coast. The distribution of the spacing between the lineaments obeys a process of Poisson which allowed estimating that 17 % of lineaments of size inferior to 2.1 km were not mapped. This network of lineaments has been analysed in order to obtain a statistical characterisation of the geometry of the aquifer blocs in the bedrock. This approach allowed studying the hydrodynamism to the local scale. The groundwater is mainly of type Ca-HCO3 or Na-HCO3. The conditions of the groundwater storage and circulation in the bedrock are studied here by using major ions. The calcic water, little or moderately mineralized is ensued from some zones of the watershed where the recharge is quite fast through some preferential paths. The sodic water is largely located at the downstream of the watershed, where the water infiltration strongly evaporated, and the cations exchange are the prevailing phenomena. The altitudes of the grounds spreading out from 70 to 210 m, with some punctual peaks of 450 m in places, and some slopes ranging from 2 to 4%. The regolith thickness pointed out a control by the lithology, and a layer less thick in the main stream’s channel valleys. From borehole data and the water level in the hydrographical network, we show that the hydrogeological watershed is a subdued version of the hydrological watershed at a depth of 10 m with some variations

Full textThe knowledge of the fracture network is a key challenge to understand the fluid circulation through a reservoir. The aim of this PhD project is to investigate the natural fracture network that channelized the hydrothermal circulations into two deep wells GRT-1 and GRT-2 at Rittershoffen (Alsace, France) that intersect Triassic sandstones and altered granitic basement in the framework of an industrial geothermal project. The structural study of the fracture network was based on acoustic image logs correlated with standard geophysical logs, whereas the mineralogical study was based on cutting samples. Permeable fracture zones of wells at Rittershoffen present an asymmetrical organization of permeability. Open fractures at the borehole scale act as fluid pathways surrounded by halos of hydrothermal alteration. These fracture zones are associated with local thermal anomalies in the temperature profiles at the borehole scale. Occurrences of heterogeneous illitic minerals could be a good indicator to prospect zones of actual and past circulations at the borehole scale

Full textThis work aims at characterizing and comparing the hydrodynamical functioning at several spatial scales within the granitic-basement and sedimentary zones of Western Niger. Then, a simple hydrological model that could be suitable for use at larger scales is proposed and tested.Qualitatively, the two geological domains have common and specific surface features.The experimental work carried out onto common surface features (biological crust, BIOL; erosion crust, ERO; fallow structural surface, ST and cultivated, C) shows that, at the point scale, ERO has the same hydraulic conductivity K value in both contexts. On the other hand, surfaces features C and especially ST have lower K values in granitic context.Monitoring of the ST and C sites along the rainy season proved the stationarity of the ST conductivity value. On the contrary, K varies widely with the amount of rain received from an initial value of 170 mm/h after weeding down to 20 mm/h (i.e. the ST measured value) after 70 mm of rain and even 10 mm/h after 180 mm of rain. This variation shows the short-term benefit of weeding onto infiltration but a degradation of the soil surface on the long term.At the plot scale (10 m2), runoff measurements are consistent with point measurements. ERO has the same runoff coefficient (Kr) in granitic and sedimentary zones while ST and C surfaces have a higher Kr in granitic context.Runoff monitoring of the granitic site cultivated plots showed that from a total of 63 rain events between 2011 and 2013, 22 had a Kr value higher than the average value (0.25) from which 2/3 are observed after the surface had received more than 70 mm rain after weeding.Results obtained at the two scales (point and 10-m2 plot) are thus consistent and show that the cultivated surface gets crusted and may produce runoff more than fallow ST sites and as much as ERO features.At the basin scale (5 ha), Kr values are higher in the granitic site, not only because of the higher Kr value for a given surface feature but also because of the specific low-infiltrating surfaces which are granite outcrops and gravel crusts (Kr = 0.58).At the three previous scales (point, plot and small basin), runoff volume was found independent of soil initial moisture.Using the previous point-scale results in a Green-Ampt infiltration model led to calibrate the wetting front pressure head for each surface feature and to satisfactorily describe runoff volumes obtained at the plot scale.By estimating runoff with the Green-Ampt infiltration model at any given point, basin-scale hydrograms were obtained by adding the contribution of all elementary surfaces. Assuming no re-infiltration of runoff water within the basins, a simple transfer function was chosen accounting for the distance of each surface to the hydrological network, a constant water velocity of 0.05 m.s-1 and a volume of 3-4 mm of water necessary to fill the kori sand cover, which is much less than that in the sedimentary context. Finally, simulated hydrograms reproduce nicely the measured ones, which offers the perspective of applying some principles of the model to larger basins
