On the Regime of Ground Water During Filtration from Channels in The Soil Layer with the Underlying Pressure Horizon

The study aims to detect ground water availability at Buhias Island, Siau Timur Selatan District, Sitaro Regency. The research method used the survey method by geoelectrical instrument based on subsurface rock resistivity as a geophysical exploration results with geoelectrical method of Wenner-Schlumberger configuration. Resistivity geoelectrical method is done by injecting a flow into the earth surface, then it is measured the potential difference. This study consists of 4 tracks in which each track is made the stretch model of soil layer on subsurface of ground. Then, the exploration results were processed using software RES2DINV to look at the data of soil layer based on the value of resistivity (2D). Interpretation result of the track 1 to 4 concluded that there is a layer of ground water. State of dominant ground water contains the saline (brackish). Location of trajectory in the basin to the lowland areas is mostly mangrove swamp vegetation. That location is the junction between the results of the runoff of rainfall water that falls down from the hills with sea water. Bedrock as a constituent of rock layer formed from marine sediments that carry minerals salts.

Main Factor

In the period 1973-1975 the depth of the ground water level and the moisture of the surface soil layer were investigated in various plant communities of the "Grabowy" range in the Kampinos Forest Complex (central Poland). The studies included a fragment of a landscape phytocomplex within which eight types of forest plant communities were distinguished. It was found that the plant communities change parallelly to the differences in the soil-water conditions (ground water level, physical properties and moisture of soils) in space.

The Impact

The use of infiltration well as a flood controller can also be useful in anticipation of the decrease in the watertable in the dry season. Infiltration well also serves to maintain the ground water level, decrease groundwatercontamination, reduce groundwater degradation, help to overcome the lack of clean water, maintain water balance in thesoil, reduce the stagnant residential areas due to poorly functioning drainage system, and reduce soil erosion in someplaces due to lack of water infiltration into the soil. The water from the infiltration well will lead to a deep soil layer sothat the decrease of the ground water surface will not occur in a short time due to its existence. Community participationin implementing infiltration wells is very functional and will significantly reduce the impact of floods. In general, infiltration wells that can help reduce surface water are those that have a well dimension of 2 x 2 x 2 meters, thusaccommodating the water volume of 8 m3 expected to be impregnated into the ground as soon as possible to cope with flooding

Penyebaran air tanah yang tidak merata dipengaruhi oleh faktor-faktor jenis batuan, bentuk topografi permukaan, jenis vegetasi dan jumlah curah hujan suatu tempat. Eksplorasi geofisika metode geolistrik tahanan jenis konfigurasi dipol-dipol digunakan untuk mengidentifikasi sebaran akuifer air tanah di desa Sea Kabupaten Minahasa. Data diolah menggunakan software Res2Dinv dan menghasilkan peta model resistivitas bawah permukaan 2 dimensi yang menggambarkan keadaan lapisan tanah. Teridentifikasi sebaran akuifer air tanah permukaan dengan kedalaman ≤ 20 m di sepanjang lintasan pengukuran. Akuifer air tanah dalam diidentifikasi pada lintasan 1 dengan kedalaman sampai 30 m dan 60 m. Akuifer air tanah dengan kedalaman< 60 m mempunyai potensi dijadikan sebagai sumber air tanahThe uneven distribution of ground water is influenced by factors such as rock type, surface topography, vegetation type and the amount of rainfall in a place. Geophysical exploration of the dipole-dipole configuration type of geoelectric resistivity method is used to identify the distribution of groundwater aquifers in Sea village, Minahasa District. The data is processed using Res2Dinv software and produces a 2-dimensional subsurface resistivity model map that describes the state of the soil layer. Distribution of surface ground aquifer with a depth of ≤ 20 m along the measurement line was identified. Deepwater aquifers were identified in l1ne 1 with depths up to 30 m and 60 m. Groundwater aquifers with a depth of <60 m have the potential to be used as ground water sources

Abstract This study presents the effect of the 3 apex angles of cone and water levels on the bearing capacity of silty sandy soil (SM) layer by interpreting results from Kunzelstab test. The SM soil layer was prepared in the testing tank and it was used as the representative of sandy soil for some area in Thailand. As the results, the cone angle increase, a number of blows increase and the adjusted factors of the blows from the apex angles of 60° and 180 º to be that of the apex angle of 90º (control) were 1.118 and 0.878, respectively. The obtained correlation between the blows and the internal friction angles of SM soil can be used for calculating the soil bearing capacity which lowers the ground surface of 0.6 m. The soil bearing capacity of SM soil below ground water level decreases 70 to 75 percent (average values from testing results) comparing to that of dry soil. Moreover, the bearing capacity of SM soil above the water level up to 0.6 m decreases 25 to 30 percent (average values from testing results) comparing to that of dry soil at the same depth. Silty sandy soil layer was found determined to have lower bearing capacity due to higher ground water level. Therefore, the calculation of the soil bearing capacity in silty sandy soil layer should be considered the effect of ground water level.

Abstract The objective of the study was the estimation of decade variation of water content in layers with thickness of 0–10, 0–20, 0–40 and 0–60 cm of a bare light brown soil in the summer half-year (May–October) in the 10-year period of 2003–2012 against the background of agro-meteorological conditions. The study was based on results of measurement of the moisture of a bare soil with the use of the TDR method, sums of atmospheric precipitations and ground water levels, conducted in the area of the Agro- and Hydrometeorology Observatory of the Wrocław University of Environmental and Life Sciences, situated in Wrocław-Swojec. The analyses revealed slight variation of mean decade values of water content in the bare soil in the summer half-year during the ten-year period under analysis. Irrespective of the thickness of the soil layer, precipitation in the 10-year period of 2003–2012 had a highly significant effect on the water content in the 2nd decade of July. In the case of soil layers with thickness down to 0–20 cm a statistically significant relation between soil water content and ground water levels was noted for the 3rd decade of May, July, and in the 3rd decade of September. In the layer with thickness of 0–60 cm the relations were statistically significant almost throughout the summer half-year, with the exception of the 1st and 2nd decades of May. Analysis of trends of mean water content of the bare soil over the 10-year period of 2003–2012 indicated their statistically significant increase in the case of most of the decades of the summer half-year only in soil layers with thickness of 0–10 and 0–20 cm.
