Water Layers

Ground water potential map showed that the Salimpaung in Tanah Datar District has very low water resources potential. Deep and shallow water resources were found in some places and in a limited area.Interpretation of imaging resistivity showed that water resources potential lies in P1 and P2 layers. This layers were found in 90 to 150 meters to the south of the mosque. The potential layer was found between 10 to 30 meter depth and thickness between 5 to 25 meter and lies in observation point between 50 – 125 meter. Water resources at layer P1, P2, P3 and P4 has medium to low potential and the water layers was interpreted as water trap above the rock layer. The other water resources potential were found at P5, P6 and P7, at 90 – 150 meter to the north of the mosque. The potensial aquifer lies beneath hard rock at depth 40 to 60 meter.

Hard Rock Terrain

Prolonged drought and improper maintenance of water resources increased the demands on ground-water supplies resulting are focuses for the need to evaluate ground-water resources in the hard rock terrain. In recent years, Remote-Sensing methods have been increasingly recognized as a means of obtaining crucial geo-scientific data for both regional and site-specific investigations. This work aims to develop and apply integrated methods combining the information obtained by geo-hydrological field mapping and those obtained by analyzing multi-source remotely sensed data in a GIS environment for better understanding the Groundwater condition in hard rock terrain. In this study, digitally enhanced Landsat ETM+ data was used to extract information on geology, geomorphology. Hill-Shading techniques are applied to SRTM DEM data to enhance terrain perspective views and to extract Geomorphological features and morphologically defined structures through the means of lineament analysis. A combination of Spectral information from Landsat ETM+ data plus spatial information from SRTM-DEM data is used to address the groundwater potential of alluvium, colluvium and fractured crystalline rocks in study area. The spatial distribution of groundwater potential zones shows regional patterns related to lithologies, lineaments, drainage systems and landforms. High yielding wells and springs are often related to large lineaments and corresponding structural features such as dykes. The results demonstrate that the integration of remote sensing, GIS, traditional fieldwork and models provide a powerful tool in the assessment and management of water resources and development of groundwater exploration plans.

Ground Water Resource

Coastal aquifers are an important ground-water resource for urban, fisheries, and agriculture areas. Coastal aquifer system at coast of Tanah Grogot Regency, at East Kalimantan Province, is important to community, but existing aquifers are not productive as ground water resources and therefore to meet community needs of water, a geoelectricity survey need to be conducted to find aquifers and this information will be used for development of water resources planning and method to be used for geoelectricity survey is rock layer resistivity. Result of this survey will identify aquifer layers as source of water. Katakunci : Wilayah pesisir, geolistrik, metoda schlumberger, satu dimensi, akuifer, air tanah, kualitas air, kabupaten pasir,tanah grogot, kalimantan timur

The geological work undertaken in the north oriental regions of Algeria have considered the plain of Tamlouka, region of Guelma, as a meeting crossroad of the three structural domains of Sellaoua, Néritic Constantine, and Tellian. The tectonic contact between the overthrust sheets is hidden by a thick alluvium cover and has remained undetermined in spite of recent exploration attempts by a geoelectric method. In this paper, we present the results of our work on the reinterpretation of the basic geoelectric data, which were founded on the calibration principle, considering all the geological information available from outcrops and cuttings of recent drill holes. Twenty-nine geoelectric profiles and three maps are drawn in which (i) the facies and geometry of the Mio-Plio-Quaternary fill are much better identified; (ii) an underground synthesis of the relation between the tectonic units is proposed after an inventory of the subsurface formations; and (iii) the ground-water potential in the plain is much better assessed.Key words: geoelectric method, geometry, overthrust sheets, ground-water potential, Tamlouka, Algeria.
