Underground Water Level

Приведен опыт в области контроля гидродинамического режима подземных напорных вод при их эксплуатации. Для измерения и корректировки результатов измерений пьезометрического уровня подземных вод в самоизливающихся скважинах использовали автономные автоматизированные измерительные устройства. Экспериментальные исследования проводили на наблюдательной скважине № 1 Мильковского месторождения подземных питьевых вод (Амшарикский участок). Результаты исследований показали, что максимальный уровень подземных вод соответствует периоду таяния снежного покрова (май–июнь). Минимальный уровень подземных вод наблюдали в апреле. Отмечено, что годовой график изменения уровня воды в скважине № 1 не соответствует полностью ни одному из типовых графиков, что свидетельствует о необходимости организации автоматизированного контроля гидродинамического режима данного месторождения подземных вод с целью защиты его от истощения и загрязнения. The experience in monitoring the hydrodynamic regime of underground pressure water in the process of exploitation is presented. To measure and correct the results of measurements of the piezometric level of underground water in blowing wells, self-contained automated measuring devices were used. The experimental studies were carried out at observation well No. 1 of the Mil’kovskoe deposit of underground drinking water (Amsharikski site). The research results showed that the maximum underground water level corresponded to the period of snow cover melting (May – June). The minimum underground water level was observed in April. It is noted that the annual schedule of the water level changes in well No. 1 does not fully comply with any of the standard schedules suggesting the need to establish automated control of the hydrodynamic regime of this underground water deposit in order to protect it from depletion and pollution.

Underground Water Level

In order to solve data lack of underground water research and monitoring situation, a wide range underground water lever dynamic information monitoring network system was designed. Remote monitoring terminal based on the techniques of embedded and wireless transmission monitored the change of underground water level; Monitoring analysis center based on the JAVA technology of B/S architecture was designed to inquiry the real-time data,set parameter and analyze data, etc. An approximate water level point was obtained by adopting the modified small period prediction model and the weight distribution method. This enhances reliability of monitored data. By utilizing the technology of GPRS wireless data transmission and Ethernet technology, a remote and real-time data transmission channel was build. Large area application in Shanxi Province shows that the system has the stable performance and the reasonable structure. System can provide long-term reliable data for underground water research.

Underground Water Level

Observation of underground water level in the area of "Jasensko-Belilo", which belongs to the Forest Estate "Sremska Mitrovica", started in 1999. The measurements were performed by means of 2 piezometers set up approximately perpendicularly to the river Sava, forming profile number 1 (Fig.1). The results of these measurements (Fig. 2, 3) show a significant lowering of groundwater level in 2000. The reason is most likely the unfavorable rainfall amount and distribution during that year (Table 2). A much better situation was during 2001 when the minimal groundwater level was up to 2 meters and it was considered to be the result of a favorable amount of rainfall and its distribution during the year (Tables 2, 3). It was noticed that Carpinus betulus appears instead of flowering ash (Fraxinus ornus), which is a good sign that generally the level of underground water is lowering. Also, the phenomenon that pedunculate oak (Quercus robur) gradually loses its natural regeneration capability also confirms the trend of lowering underground water level. If this trend continues, oak will be in a very near future naturally substituted by less valuable species, probably Turkey oak (Quercus cerris). If groundwater wells along the river Sava reach the vicinity of this area, which is a plan for the Belgrade city water supply, the trend of groundwater table lowering will be even more expressed and it will certainly endanger the existence of all valuable forest species in this area.

Numerical simulations were carried out to investigate the current situation of underground water and its variations rule resulting from site grading at a proposed iron and steel base in Xichang. The comparison shows that the numerical simulations results of underground water level tally with measured results very well. On the basis of the simulation analysis result of current situation of the underground water, its variations rule after site grading was simulated and forecasted. The results show that after site grading, due to recharge, discharge and runoff conditions of underground water have be changed, the underground water level at the dig, fill section and the edge of the site would also be changed too. Specifically, the underground water level of dig section lowers than that before site grading while fill section’s higher than before.

Canal bridge and aqueduct main foundation types include well column, pier, bored piles, bent pile etc. Most of these foundations are in low-lying conduit. The water content of foundation soil is very rich. Especially pile foundation in the drain, due to the high underground water level, pile foundation around soil is in a state full of water. So such type of foundation freeze injury phenomenons are very serious. In order to solve such freeze injury problems, some antifreezing measures are adopted.

Water Transpiration

The experimental studies permitted to determine the ratio between infiltration and transpiration of the ground water in a soddy podzolic soil, that accounts for 0.3-0.6 under dried conditions of atmospheric moistening, 2.6-2.9 as an average value for many years and 2.6-2.9 under moderately wet conditions. The loss of potassium, calcium, magnesium, zinc and manganese under the grass stand was calculated as 0.95, 89.0, 37.7, 1.42 and 1.40 kg/ha/yr respectively. Due to capillarity the root layer of this soil receives 0.19 kg/ha of potassium or 20% from its loss with water infiltration, 16.4% of magnesium, 15.0% of calcium, 13.4% of zinc and 9.0% of manganese. It is shown that the water transpiration in case of the close underground water level leads to rupture of capillary links. With increasing the soil thickness in lysimeter the water infiltration and the nitrate leaching become declined both under grass and beangrass stands.
