Mesopotamians used irrigation to water their crops.
What is the Necessity of irrigation?
Throughout the crop period adequate quantities of water is required near the root zone of the plants for their growth. At times during the crop period the rainfall may not be adequate to fulfill the water requirement. The intensity of rainfall is practically uncertain and beyond the control of human power and it may not be well distributed throughout the crop season or the culturable area. So, irrigation becomes absolutely necessary to fulfill the water requirement of crops. The following are the factors which govern the necessity of irrigation, (a)Insufficient Rainfall: When the seasonal rainfall is less than the minimum requirement for the satisfactory growth of crops, the irrigation system is essential. (b)Uneven Distribution of Rainfall: When the rainfall is not evenly distributed during the crop period or throughoutthereculture able area the irrigation is extremely necessary. (c)Improvement of Perennial Crops: Some crops like sugarcane, cotton, etc require water throughout the major part of the year. But the rainfall may fulfill the water requirement in rainy season only. So for the remaining part of the year, irrigation becomes necessary. (d)Development of Agriculture in Desert Area: In desert area where the rainfall is very scanty, irrigation is required for the development of agriculture.
What is canal outlet?
A canal outlet refers to a structure or opening through which water is discharged from a canal system. It is a crucial component of an irrigation network that allows the controlled release of water from a canal to supply irrigation channels, fields, or other water distribution systems. The canal outlet serves to regulate the flow of water, ensuring it is distributed appropriately and efficiently. Canal outlets can take various forms depending on the design and purpose. Some common types of canal outlets include: Head Regulator: A head regulator is a type of canal outlet that is typically located at the beginning of a canal system. It is used to control the flow of water into the main canal from the water source, such as a river or reservoir. Distributary Regulator: A distributary regulator is a structure located along a canal where it branches off into multiple distributaries. It regulates the flow of water into each distributary, ensuring an equitable distribution of water to different irrigation channels or fields. Flume: A flume is a channel or chute-like structure used to carry water from a canal to an irrigation channel or field. It is often made of concrete or lined with a smooth surface to minimize water loss due to seepage. Flumes can be designed to maintain a constant water level and control the flow rate. Turnout: A turnout is an outlet structure that diverts water from a main canal into a smaller irrigation channel. It allows water to be directed to specific fields or areas for irrigation purposes. Sluice Gate: A sluice gate is a mechanism used to control the flow of water at a canal outlet. It consists of a movable gate or barrier that can be raised or lowered to adjust the water level or stop the flow completely. Canal outlets play a vital role in managing water resources efficiently, ensuring that water is distributed effectively to meet agricultural, industrial, or domestic water needs. The design and operation of canal outlets aim to minimize water loss, maintain flow control, and optimize water distribution for irrigation and other purposes.
What is the objectives of stone masonry in irrigation canal?
Masonry is used to line water courses to prevent erosion of the banks.
Why there is greater empisis on minor irrigation projects than on multipurpose projects?
Irrigation projects servicing a command area of less than 2000 hectares fall under the category of minor irrigation projects.These projects have received priority in the realm of agricultural development due to their relatively high advantages over the traditional irrigation methods. Minor irrigation projects by definition cost less than Rupees 25 lakhs(2.5 million).They are easy to build and maintain.Their operation is under the farmers control.Other advantages include short gestation period,low investment and low probability of enveronmental erosion. A Large number of these projects are based on ground water utilization using modern methods and technology.It must be ensured while doing so that wells are spaced appropriately to ensure economic sustainibility.Modern irrigation techniques like drip irrigation and sprinkler irrigation are used to maximise water utilization and avoid erosion of aquifers. In India NABARD is playing a stellar role in propagating and facilitating Minor irrigation by proving the adequate financial and technical know how to the farmers.

Why did Sumerians build levees canals and dams?
The Sumerians used levees, canals, and dams for controlling water. These are all different systems of irrigation. With levees, canals, and dams the Sumerians had a reliable water source. They had plenty of water for their crops. These systems of irrigation helped bring neighboring communities together. When there was a problem with the dam, canal, or levees, the people around would help each other out by taking care of their systems of irrigation
