What is Hydrology in Civil Engineering?

Hydrology is one of the essential concepts in civil engineering, which requires the focus of aspirants. Hydrology is the study of the movement, distribution, and management of water in the environment.

So our article will talk about the basics of hydrology and some of its major concepts.

The Basics of Hydrology

Hydrology is associated with the study of water in the environment. It involves several key principles and processes:

• Hydrological cycle: This cycle consists of the continuous movement of water on, above, and below the surface of the earth.
• Precipitation: This process consists of water falling from the atmosphere in the form of rain, snow, sleet, or hail.
• Evaporation and transpiration: Evaporation is where water changes from a liquid to a vapor form. In transpiration, plants release water vapor through their leaves.
• Runoff: It is the movement of water over the land surface into streams, rivers, lakes, and oceans.
• Infiltration: This is the process by which water seeps into the soil from the land surface.
• Groundwater flow: Water that infiltrates the soil and moves underground through absorbent rocks and soil layers.
• Streamflow and River hydraulics: This is the study of water flow in rivers and streams.

What is hydrology, and what is its Importance in construction?

Hydrology is the study of water flow in the environment; it understands how water interacts with the earth’s surface and atmosphere. It plays an important role in constructions such as:

• Site assessment by evaluating water availability, soil moisture, and groundwater levels.
• Flood risk management will ensure that the structure is built above possible flood levels.
• Drainage design to prevent water logging.
• Water supply to ensure reliable water sources and long-term supply.
• Mitigating the environmental impact of construction.

A brief introduction to hydrology is not enough to gain knowledge, so we have linked below some major key concepts with their in-depth explanations that will be beneficial for students preparing for CE exams:
