Bhoojal Survey

  What is Hydrogeological Survey ? A hydrogeological survey also known as groundwater survey is a study performed to locate water bearing zones beneath earth surface for groundwater extraction purposes through borewell. A hydrogeological survey is carried out by experienced hydrogeologist using resistivity meter or Magnetic resonance technology based instrument. It explores the water-bearing rocks and aquifers beneath the surface of the earth A hydrogeological survey is a comprehensive study conducted to understand the distribution, movement, and quality of groundwater in a particular area. This survey combines principles from hydrogeology, geology, and hydrology to assess water resources and their interactions with the surrounding environment For more details visit https://bhoojalsurvey.in/hydrogeological-survey.php What is the importance of hydrogeological survey ? A Hydrogeological survey carried out at a site can locate potential water bearing zones , Depth of wa

Wenner method for earth resistivity test The Wenner method is a technique used in geophysics for measuring the electrical resistivity of subsurface materials. It is named after Frank Wenner, who developed the method in the early 20th century. Equipment : Typically, the equipment includes a resistivity meter, cables, and four electrodes. The electrodes are placed in a specific configuration depending on the method used (e.g., Wenner, Schlumberger, or dipole-dipole). Soil Resistivity test using Resistivity meter   Visit https://bhoojalsurvey.in/ for more details  Here’s how the Wenner method works for earth resistivity testing : Setup : Four electrodes are placed in a straight line with equal spacing (usually denoted as ‘a’). The electrodes are labeled as A, B, M, and N. Electrical Current : A known electrical current (I) is passed through electrodes  A and B. Voltage Measurement : The potential difference (V) between electrodes M and N is measured. Calculation : The electrical resis
