The knowledge test is done by choosing the method of surveying methods, geophysics 2 measurement of electric resistance thankrasae a widespread condition (Vertical Electrical Sounding: VES) and electric resistance measurement method, thankrasae 2 (2D Imagine) to compare the advantages disadvantages of each method in looking for stones to absorb groundwater in areas where there is groundwater salinity. T. Nam Phong A. water Pong. Khon Kaen province study both electrical resistivity method can be classified and compared with information leading chandin rocks. And compare how the two surveys: how good is able to distinguish between VES shelf sediments and rock or salt water layer at the bottom. A survey of more than 200 m depth and exploration equipment can be transported and found drawbacks that cannot be explored in areas where there is a thick, sticky, or leading chandin salt water cover above. The value of the electrical resistance values as the Prague datong is going to be interpreted and calculated into actual electrical resistance values. Need to take some time to translate the meaning and value of specific electrical resistance of the different rock layers chandin. Unable to determine the exact value vary, it's difficult to Imagine how the 2D section translation has the advantage is able to display the difference of the electrical resistivity, low-high. And you can avoid a liangboriwen salt water. Disadvantages: there is a lot of peripherals. Team and long time required to make a survey of the area is less than the VES. Need a space to explore and survey equipment is expensive.

Test their knowledge by choosing to explore the geophysical second is how to measure the resistivity of electricity a deep (Vertical Electrical Sounding: VES) and a method of measuring the impedance and two-dimensional (2D Imagine) to. Compare the pros and cons of each approach in exploring for aquifers, groundwater in areas where groundwater salinity treatment. Nam Phong district, Nam Phong, Khon Kaen. The results of both methods can be classified resistivity and comparable information topsoil layer. Stone The results of the survey and compare the two types VES advantage of being able to distinguish between the layers of sediment and rock or brine layer on the bottom clearly. Explore more than 200 meters long and can transport easily explore and discover the disadvantages can not explore in a thick layer of clay. Or a salt-covered floor above. The value of the survey is a specific electrical resistance turns out to be interpreted and calculated to be in the actual electric resistance. Need to take some time to interpret. And the specific electrical resistance of the layer of shale. You can not set fixed it difficult to interpret the 2D Imagine how has the advantage of showing the difference in resistivity low to high - clearly. And to avoid areas where water is expected to be precisely the downside, however, is a very peripheral. Requires team work and a long time to make a survey of the area less than a VES. Require a lot of space to explore and survey equipment is expensive.

The test by choosing how to geophysical techniques 2. Measuring the values of the current ต้านท a deep (Vertical. Electrical Sounding:VES) and measuring the electrical resistance model 2 dimension (2D Imagine) to compare the advantages and disadvantages of each method in the exploration for aquifer groundwater in areas with groundwater salt layer Nam Phong District, A. oils.)Khon Kaen both methods can be classified the resistivity of comparable data and I ดินชั้น stone. Summary of survey and compare the 2 model as follows: how VES advantages.While more than 200 survey meters. And the survey equipment can move conveniently, and find the disadvantage is unable to explore in the ที่มีชั้นดิน thickness. Or have I brine off over the top.Take some time in interpretation. The specific resistance of soil and rock. Cannot specify fixed, it is difficult to interpret the 2D Imagine has advantages.And can avoid the expected water salty accurately. Disadvantages found was a peripheral devices. To use the team and a long time to explore the area less than a VES.
