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. Calculatio...

For centuries, groundwater has served as an invaluable resource, holding immeasurable worth for humanity. With its substantial consumption, India stands as the global leader in utilizing groundwater resources. For the judicious and sustainable utilization of groundwater resources and their management, Central Ground Water Board (CGWB) holds significant importance as an apex institute in India because the primary source of drinking water in India is groundwater. CGWB which operates under the Ministry of Water Resources, Government of India, is the premier national organization responsible for delivering scientific expertise in the management, exploration, monitoring, assessment, augmentation, and regulation of the country's groundwater resources. For this matter, CGWA issues NOCs (No Objection Certificates) as proof that proposed projects and operations that involve the extraction of groundwater for domestic, commercial, or industrial use comply with all applicable regulations. So, ...
