The scientists developed a method to estimate how easily water flows through different directions in a coastal area in India. They used data from underground scans and water conductivity to figure out how porous the ground is and how fast water can move through it. By looking at the clay content in the ground, they found a way to predict how well water can flow horizontally and vertically. Their method was tested in Karnataka, India, and matched well with traditional tests. This new approach can help understand how water moves in areas with clayey soil, which is important for managing groundwater.
