The first irrigation system canals and dikes were developed by the ancient Mesopotamians, particularly the Sumerians, around 4500 BCE. They constructed these structures to control water flow and direct it to their fields for agriculture.
The ancient Mesopotamians, specifically in the region of Sumer, developed some of the earliest known irrigation systems with dikes and canals around 6000 BCE. These systems were essential for managing water flow and cultivating crops in the arid region.
There are no dikes or canals in Southwest Asia as those things would require an abudance of water, which Southwest Asia lacks.
To bring water into towns and villages.
Hittites
They lived in the desert with the Nile as the only source of life -- irrigation for growing crops, so they could eat, canals and the Nile also used for transport of people and goods, sometimes pieces of architecture.
The water is controlled by dikes and ditches.
They dug irrigation canals and ditches. They then added gates and dikes so that they could use the water to nourish their crops without flooding.
this is true.
The first irrigation systems, with dikes and canals was created over 10,000 years ago, we do not know for sure which people it first originated.The first civilization, which used these systems, was the Mesopotamian's to which most anthropologists accredit with this advancement.
Because they rely on dikes for their local crops and marshlands
The Sumerians were the first to build an irrigation system. They learned how to use the floodings of the rivers to water their plants. They dug canals in which they could store the water and made gates (dikes) to protect their lands from flooding. When the river went back to its banks, the gates were closed and a lot of water remained in the canals. Without this knowkledge (and hard work) they just wouldn't have been able to live and farm in the very hot weather.
