Introduction: Civil engineering?
Civil engineering is a fascinating field with a rich history dating back to the very beginning of human civilization. It’s the story of how we, as humans, have learned to manipulate our environment to meet our needs, from basic shelter to complex infrastructure. Let’s explore this interesting journey from ancient times to modern marvels.
The Origin of Civil Engineering
Imagine traveling back to around 4000 BC, when humans were just starting to settle down and build their lives near the Tigris and Euphrates rivers in Mesopotamia. This lush region was perfect for their early cities like Ur and Uruk to grow and thrive. These cities depended on the rivers for everything—water for crops, fish to eat, and a means of transportation.
But life wasn’t always easy. Since the river is so close to villages and communities, it can flood unexpectedly, which is sometimes even more problematic. So to cope and solve problems, these ancient Mesopotamians became experts at finding ways to control rivers. They invented clever ways to manage water, such as digging canals to carry water to their fields and building strong dams (early dams were constructed using materials such as mud bricks, stones, and wooden planks to divert water) to control flooding -/ It wasn’t just about making life easier; it was about making sure they had enough food to eat and that their cities could continue to grow||
Their idea of building dams to control water flow was incredibly smart. Stores the water for later use. That was the time when they laid the foundation of engineering.
Transition from Military to Civil Engineering
When discussing the origin of civil engineering, it’s important to recognize its roots in military engineering. Military engineering, one of the oldest engineering branches, focused on designing and constructing military works and fortifications. The term “engineer” comes from the Latin word “ingeniator,” meaning someone who constructs military engines or machines. Thus, the foundation of civil engineering can be traced back to early military engineering developments.
