For laying of the foundation, design of the irrigation system and also to dig well it is necessary to know level of underground water on your farmstead site. How it is correct and with the smallest expenses to define it?
1. Remember that availability and amount of underground waters in soil depends on the soil in your area. The melkozernisy it can accumulate composition of the ground, the less water. Clay and loamy soils do not may contain water and are waterproofing course. It is possible to recognize level of underground water by the external signs specifying on availability of water in the soil layers which are close located to surface. Points out emergence close arrangement of underground waters in the mornings and to evenings of fog over certain places of the site, congestion of small insects, availability of cane or sedge.
2. For obtaining information on how there is deeply underground water, be guided by wells and other sources of water near your site. It is possible to determine by them, though approximately, the level of groundwater occurrance in your area. After the water source located near your site is found, learn level of underground water by means of barometer. Measure pressure on the place of the operating reservoir in the beginning and compare it to that which you have received on the place where it is required to learn level of underground water. If in the first case the device shows more high pressure, than in the second, then the depth of underground waters on your site will be quite big. Remember that the depth of underground waters in the area decides on equal relief by the above-stated way. If underground waters are located obliquely, then when calculating it is necessary to do the correction on their bias. In mountain areas for the solution of objective it is necessary to address the expert.
3. If your site is located on the floodplain or within the river valley, then it is possible to determine depth of underground waters by method of comparison of excess of the expected place of measurement of level of underground water over river level. Since the water-bearing layer is directly connected with the river, it is possible to draw conclusion that the depth of underground waters will be no more than height of the coast.
