2.1 Irrigation
2.1.1 What is Irrigation?
There are many definitions of irrigation but in simple words it can be technically described as an artificial or mechanical way of supplying water to land for agricultural purposes at the right time and in right amount for the proper growth of the plants in order to get the maximum yields of cultivation.
But irrigation also includes clearing away of excess water from the agricultural land.
Irrigation has been a central feature of agriculture for over 5000 years and the result of work of many cultures, and was the basis of the economy and society of numerous societies, ranging from Asia to the American Southwest.
2.1.2 Necessity of Irrigation
Irrigation has always been necessary and there are many

There are many ways in which it can be done. Various techniques of irrigation have been developed in order to supply the entire field the uniformly with water so that each crop gets right amount of water, neither too much nor too less, just correct amount. All the techniques of irrigation differ with each other only in the way they distribute the water obtained from the source. These techniques are described below:
2.2.1 Surface irrigation:
It is also called as flood irrigation. It is the most common way of irrigating land and is being practiced by human beings from thousands years. In this irrigation system, in order to infiltrate the soil and to wet it, water moves over and across the land with the help of gravity flow.
Further it can be divided into following categories:
1. Furrow irrigation
2. Border strip irrigation
3. Basin irrigation
Due to its nature of creating a situation of flood in the cultivated land it is called flood irrigation. Surface irrigation
2.2.2 Localized Irrigation
Piped network is used in this irrigation system. With the help of this network, water is distributed under low pressure in a pre- determined pattern and applied as a small discharge to each plant or adjacent to it. There are many types of irrigation system which belong to this
They way how irrigation chance yuma arizona. When irrigation first started in 1912. Since then they had low amount of farms, acres. And number of towns. Those number started to increase little by little through the years.
Freshwater is also looked at as floodplain management is observed. The patterns of environmental quality are also examined. My hypothesis is that pH levels and drainage account for the significant differences in vegetation between the areas. This is because both drainage and pH levels play a role in what type of soil is available. The pH level determines the types of plants that grow and the drainage effects the type of soil present, which influences the
Fertile Agribusiness in yuma has evolved to help model for efficiently using maximize agricultural production and economic value. By using irrigation we improve efficiency and judicious switching to less dried up crops we can use less water,
Agriculture shows other countries what to do, as well as how to use other drip systems to help the control of water. Water is an essential necessity for crops to be maintained well. We have a canal that runs from Algodones to Yuma which is the main source for water without it we would not be able to maintain the crops that that farmers grow. Many farmers use different water systems such as dykes levees in canals or your irrigation systems sprinklers and others sorts . Agriculture has changed significantly in Yuma over four decades the 1970s focus on material crops such as alfalfa and citrus or season crops such as cotton or the main winter crop was the wheat which served as a transition crop for rowers protein from Contillo papa or the second crop that were the best watermelons less than 17% of land was planted two vegetables in the 1970s only 10% of the land was dedicated to multicraft
To make up for that, a new invention was created, sprinklers. Sprinklers made it easier on produce growers because it reduced the amount of water being wasted and did not require as much labor as basic water
Yuma, Arizona a state that was officially established in 1912 came to be one of the most and main important areas in irrigation and agricultural history as it grew and progressed and was founded by many. All Southern Arizona contributed to the significance of this history along with Yuma as well. With the Colorado River as the main supply and running through these areas supplying water creating other dams and canals such as the Yuma Siphon, Yuma Main Canal, Laguna Dam, All American Canal etc. Question Number one, Describe in detail how irrigation changed Yuma/ South Arizona.
Ancient Civilizations Egypt, Mesopotamia, and India are some of the early civilizations, that helped to shape the world as we know it. Each ancient civilization had many contributions to society. Some would include irrigation, grid like house system, and written languages. Ancient Egypt is one of the most common ancient civilizations. We all know them for the pyramid but that 's not all that they achieved.
Places that have sparse or seasonal rainfall could not sustain agriculture without irrigation. In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. In document 3 it says "These irrigation systems was the first of their kind and allowed Mesopotamia to grow a surplus of wheat and other crops." this shows why irrigation systems are important and how they impacted the world.
The most common definition of runoff is precipitation that is in an uncontrolled flow of water. The uncontrolled movement of water can be in parking lots on commercial zones of property, on streets in low-lying areas, and any other situation where water does not flow on a typical sunny day. The runoff will eventually flow into surface streams, rivers, drains, or sewers. (Howard Perlman, 2015) The runoff is caused by gravity, assisting water flow, and is aided by little absorption by soil.
Growing a Surplus Egyptian farmers built walls around fields to trap the Nile’s flood waters. The water soaked in the soil and allowed grains to grow. This form of crop irrigation allowed farmers to produce a food surplus(amount of food greater than the their family’s needs). The Birth of Cities These local rulers used this surplus to buy rich cloth and other goods.
Although they had 2 water sources, the harsh warmth that came from the tropic of cancer caused droughts and dryness in the lands. With dryness crops and farms were depleted of resources when provided the entirety of the civilization. However, occasionally the rivers would flood leaving a layer of rich silt. Now that you have a rough idea of life, my explanation on why Mesopotamia was a civilization continues. As I mentioned before regarding the depleted resources, new ways were mandatory in order to put a plug on the famine that spread.
Have you ever wondered what Agricultural Revolution was and if it had a positive or negative effect on human civilization? Well, the Agricultural Revolution had a huge effect on civilization. It was when humans discovered how to farm! This took place from about 10,000 B.C to about 3,000 B.C. I believe it had a positive effect on human civilization for a couple of reasons.
Poldering is the provision of a ring bund surrounding the area to be protected. This is normally carried out for an area which has high damage potential but for which the cost on overall basin-wide protection would be prohibitive. It includes the provision of internal drainage for the area to be protected and the evacuation of flood water by pumping during periods of high river flows. Canalization also suitable in overcome flash flood. Canalization works include the widening and deepening of channels as well as lining the banks and beds of the channels.
2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills. There are also small rivers that filled up to be used as a building site. Activities such as these are a common factor of flooding. In the past, creeks and valleys turned into water flow, now the area has been covered with soil.
Introduction By the year 2025, the Philippines is believed to be brought to a water crisis if no new sources of water are developed or found to meet the growing demand of the citizens. (Sapnu, R., Balabo, D., & Cervantes, D., 2007) "There is a Japan International Cooperation Agency study that says that if we will not conserve water, there may be some problems. But of course we can always start conserving now and look for other sources," Lopez (2013) said. Studies have shown how water conservation and appropriate water utilization are significant as early as today.
