Flood irrigation system

Bac Ninh is a province with a dense network of windows from 1.0 -1.2 km/km2 with large river systems flowing through Duong River, Cau River, Thai Binh River and the downstream part of Ca Lo River. With a dense river system and abundant surface water saving, the province’s irrigation plays a particularly important role in water harvesting, drainage and flood prevention in the province. Over the years, the province has focused resources to invest in the development of irrigation infrastructure.

The spillway is one of the most important construction components in the irrigation system; it is the key to ensuring the safety of the reservoir. In this study, the 3D-Fluent numerical model is used to simulate the hydraulic regime in the Ta Hoet spillway. The 8 simulation cases include different gate opening modes and variable flood flows.

Rice is commonly grown by transplanting one month-old seedlings into puddled and continuously flooded soil which leads to higher losses of water through puddling, surface evaporation and percolation. Excessive pumping of water for puddling causes problems of declining water table and poor quality water for irrigation.

Water is the most valuable resource in the world and is playing a crucial role in daily activities of living beings on the earth. To meet the ever increasing demand, conservation and management of water resource is very important. Conventional methods of irrigation, like surface and subsurface flooding leads to scarcity of water, which can be reduced by adopting drip or trickle irrigation. Drip irrigation system can be controlled through different automation techniques.

The present study was programmed in 2014-15 to evaluate the efficacy of the varied components of precision farming systems comprising drip irrigation (80% ER), fertigation (75% RDF), micronutrient foliar spray (Commercial formulation ‘Tracel’2%), bunch spray of sulphate of potash (2%) as well as black LDPE film (50µ) mulch over the traditional system of soil nutrient application (110g N, 33g P2O5 and 330g k2O) and flood irrigation (15 day intervals) in ‘Grand Naine’ banana. Components of precision farming significantly increased bunch yield. The highest bunch weight (21.

Drip system of irrigation provides enhanced water use efficiency and water application efficiency up to 90% whereas it is about 70% for sprinklers and 45% for flood method of irrigation. In this method as water is supplied directly to crop root zone through drippers, water losses in distribution and conveyance are far lower than those under flood irrigation. A case study was conducted regarding performance evaluation of drip irrigation system used for growing brinjal in the village Shivpur, district Mungeli in Chhattisgarh.

Micro irrigation systems endow lot of water saving for future crop and expand the land under cultivation with sustains the soil healthy for sustainable growth towards achieving growing food grain demand. Keeping this, the present on-farm trial was conducted in a farmer field of Gumthala Garhu village of Kurukshethra district, Haryana state. For assessment of rice yield, three different irrigation methods viz. drip, sprinkler and flood irrigation methods were adapted.

Photovoltaic based electricity generation saves a major portion of renewable energy generation in India. Ever increasing fuel cost and doubtful availability of electricity hampers the irrigated crop production. Use of solar pump is an alternate to electric or diesel pumps for irrigation of crops. This paper presents the utilization of solar power for operating micro irrigation systems for irrigating field crops. An open well submersible pump of 5hp capacity was operated by 4960Wp solar panel installed at ICAR-CIAE, Bhopal for irrigation.

Meanwhile, humans were learning to harness other forms of energy. The earliest known use of wind power is the sailboat.[40] The earliest record of a ship under sail is shown on an Egyptian pot dating back to 3200 BC.[41] From prehistoric times, Egyptians probably used the power of the Nile annual floods to irrigate their lands, gradually learning to regulate much of it through purposely built irrigation channels and 'catch' basins. Similarly, the early peoples of Mesopotamia, the Sumerians, learned to use the Tigris and Euphrates rivers for much the same purposes.

Hydraulics is a branch of scientific and engineering discipline that deals with the mechanical properties of fluids, mainly water. It is widely applied in many civil and environmental engineering systems (water resources management, flood defence, harbour and port, bridge, building, environment protection, hydropower, irrigation, ecosystem, etc). This is an introductory book on hydraulics and written for undergraduate students in civil and environmental engineering, environmental science and geography.
