What does hydrology study in relation to earthworks?

Hydrology is a field of study that focuses on the distribution, movement, and properties of water in the Earth's atmosphere and on its surface. In relation to earthworks, understanding how water interacts with soil and landforms is crucial for several reasons, such as managing erosion, optimizing drainage systems, and ensuring the stability of construction projects.

The knowledge gained from hydrology directly influences decisions around the placement and design of earthworks, including the construction of roads, embankments, and drainage systems. By studying the patterns of water flow and how it saturates or erodes soil, professionals in earthworks can develop methods to mitigate potential problems that arise from water accumulation or runoff.

Therefore, the focus on the distribution and movement of water is key to effective earthwork planning and execution, making it fundamentally important for environmental management and civil engineering projects.
