How do they build dams?

People started to build dams to create a reservoir of water that can be used for domestic purposes such as drinking, irrigation, and for some advanced purposes such as generating hydroelectric power. The process of constructing a dam can vary depending on the materials available and the dam’s size, but some general steps are followed in most cases. In this article, we’ll take a look at how dams are built and what role each step plays in the overall process.

What is a dam?

Dams are structures that are built to hold back water usually built across rivers or streams to make reservoirs , which can provide water for cities, irrigation, and hydroelectric power. Dams also consist of sub-parts such as valves, water control gates, and external waterways.

How to build a dam

Building dams has never become an easy feat. For the structure to not collapse and to be steady and stable It requires a lot of planning and engineering. Here are the basic steps that need to be taken in order to build dams:

  1. Finding the right location: The first step is to find a suitable location for the dam. The site must be assessed for things like geology, topography, and hydrology.
  2. Designing the dam: Once a suitable location has been found, the next step is to design the dam. This involves creating plans and models of the structure.
  3. Constructing the dam: The next step is to construct the dam. This involves pouring concrete, erecting steel supports, and installing any other necessary components.
  4. Testing the dam: Once the dam has been constructed, it needs to be tested to make sure it is stable and will not collapse. This usually involves conducting stress tests on the structure.

Dams have their own pros and cons,

The pros of dams

Dams are amazing engineering feats that provide a variety of benefits to the society.

  • As we mentioned earlier, they can be used domestic purposes and for irrigation, flood control, hydroelectric power, and water storage.
  •  Dams can also assist to create recreation areas and support wildlife populations.
  • There are many different types of dams, but they all serve the same purpose: to block the flow of water.

The cons of dams

Dams have been used for centuries to control the flow of water, but they can have some serious disadvantages.

Well, folks, as with all things in life, there are some downsides to damming up those rushing rivers. One of the biggest issues is that it can make life difficult for our finned friends – that’s right, the fish! Dams can get in the way of their migratory patterns, which can be a real problem for some species. I mean, who wants to swim upstream only to find a big ol’ wall in your way, right?

But that’s not all, folks. When we humans build dams, we can unintentionally cause some serious erosion and sedimentation. This can lead to a build-up of sediment in the reservoirs behind the dam, which can reduce the amount of clean water downstream. Talk about a dam shame!

And let’s not forget about safety. If dams aren’t designed or maintained properly, they can be downright dangerous. Nobody wants to see a dam fail, causing destruction and putting lives at risk. So, let’s all work together to make sure our dams are safe and sound, and that our aquatic friends and communities downstream can continue to thrive.

Types of dams

With the advancement of architecture many ways to build dams were introduced, There are different types of dams, each with its purpose and design. The most common and popular type of dam is the gravity dam, which uses its weight to hold back water. Here are a few other types of dams include arch dams, buttress dams, and embankment dams.


Now you know that it requires careful planning and execution to ensure that the structure is stable and able to hold back the water. The first step to build dams is to determine the location and what materials will be used. Next, the foundation must be dug out and laid down before the walls of the dam can be built up. Finally, the dam is finished off with a waterproof coating to prevent leakage. This shows that it is very useful for domestic purposes of humans and represents the creativeness of humans.
