Hydraulic Engineering Services: The Uses and Functions of Hydrological Modelling

13 March 2020

Today, managing water resources is crucial when developing architectural or engineering projects. Hydrology is the science that covers the properties of the world’s water along with how it moves in relationship to the land. Using this science, hydrological modelling has been developed to analyse real-world situations, such as soil water, surface water, groundwater, wetlands and more in order to understand, manage and predict water resources accurately. Not only is the quantity and quality of water included in this modelling but also the flow of it. We discuss this modelling in a bit more detail in the following.

Special Software Is Available Today for Hydrological Modelling

With the use of specially designed software, the hydrological modelling results are highly accurate. The software helps organise and analyse all pertinent information dealing with the hydrologics of a particular project site.

Understanding Hydrologic Processes

Numerous quantitative measurements on various scales are necessary to gain understanding of the hydrologic processes in any location. The usefulness of hydrological modelling is dependent upon its output of spatial and temporal resolutions for any water issues.

Functions and Uses

Hydrological modelling is used for many different purposes at present, including:

• Analysis of surface water flow over land and through channels along with groundwater amounts and flow direction. Flow direction is crucial in calculating drainage plans for a project.
• Discover sound remedies for any problems with analytical solutions and empirical equations to ensure that there are no lingering issues once the project comes to completion.
• Accumulating and calculating data about precipitation amounts of rainfall and snow melt along with their effects on the groundwater. With this data, droughts even can be predicted and planned for effectively.
• Water loss through evapotranspiration, which is a normal process of water evaporating into the atmosphere from the land, plants, various surfaces or bodies of water.
• The peak flow and volume of runoff. For example, right after heavy rainfall that runoff flow with be at its highest and heaviest.
• Catchment area planning to ensure that a project site has sufficient natural drainage as well as manmade drainage assistance.
• Projection of future runoff and overall water conditions to guarantee that the ongoing water supply and drainage is as adequate as humanly possible.

Many Can Benefit From the Information in a Hydrological Model

Read on to learn the many entities that may benefit from hydrological modelling:

• Cities, towns and municipalities
• Architects
• Construction companies
• Engineers
• Owners of residential and commercial properties

If you are in the midst of planning a project, do not make the mistake of ignoring the benefits of the information that hydrological modelling will provide to you. It can make the difference between total success and failure of the results of your project.
