Here are some key reasons why geology is important to civil engineers:

Understanding Ground Conditions: Geologists study the earth's materials and structures, helping civil engineers assess the stability of the ground and identify potential risks such as landslides, earthquakes, and soil erosion.

Site Investigation: Geological mapping, borehole drilling, and geophysical surveys are used to determine the soil's compactness, water table depth, and other critical factors that affect construction.

Material Selection: The type of soil, rock, and groundwater present can influence the choice of construction materials and methods, ensuring the project's durability and safety.
