That is, during the rainy season they need to store the water so that they can manage the next summer season. This river was selected first as fields which are situated in the banks were flooded often in a single year. So the best method to stop this is by building an irrigation system in its banks.

Secondary function of the irrigation system

The irrigation system’s secondary function was to divert the flow of excess water during the rainy seasons which caused flooding of the agricultural fields. These were also used for transportation purpose. Some



military persons or vessels travel through this irrigation system only. This is because this is the cheapest way to move on as they need work to row the boats as they will move downstream along with the river. By implementing these irrigation systems, the Chinese were also able to solve the problem over water between the neighboring agricultural field owners.
