The Guhai dam is located on Guhai River near Village Khandhol in Himmatnagar taluka of district Sabarkantha. The Latitude and Longitude of the dam are 23’42’00” N and 73’3’24”E,respectively.
Its purpose are irrigation and flood control. The catchment area of the Guhai River at the dam site is 422 sq. km. The dam was completed in the year 1990. The FRL and HFL of the dam are at a level of 173.00 m and 173.77 m respectively. The dead storage and live storage capacity of the reservoir are 5.30 and 57.04 MCM,respectively.
Under guhai project right bank canal is 21 km long which passing through 31 villages of himmatnagar taluka and by this canal 7111 ha area is irrigated.
From field observation, satellite data analysis and schemes implemented following observations are highlighted:
• The watershed is characterized as forested/woodland. • Significant increase in the area under very good vegetation cover. Moderate to good vegetated area as been turned to very good vigour type, a healthy symbol of watershaded development.
• Tremen dous increase in spatial distribution of block plantation (horticulture/forest), also improved pastureland cultivation in dry lands. Crop area has remained the same over years (15.38% and 15.48%).
• Good response in the live stock management.
• There is still scope to improve the crop lands (alluvium derived soils) by adopting new farming techniques and water conservation measures.
• Dryland could be further impro...

..., the following recommendations are made :
• Removing obstructions to the flow such as weeds , bushes and other vegetation from the stream at regular interval from main canal and distributary canals.
• If the water supplied to the cultivators is assessed on area basis , the cultivators have a tendency to use excessive water , by adopting the volumetric assessment of water is controlled.
• The distribution of water to the farmers should be managed properly by using some kind of rotation system such as wara bandi.
• The farmers should be trained and educated through courses organized regularly about economic use of water and methods of application of water such as sprinkler irrigation and drip irrigation.
• Proper arrangement for the measurement of irrigation water used by the farmers should be made to facilitate the collection of water charges from the farmers.
John Adams Dam was built on another Genesee River tributary to form a recreational pond affecting 43.78 miles of river (Fish, n.d.). There is a small, unnamed barrier affecting 3.16 miles of Genesee River tributary in the center of the park. I assume that it had been used during the building of walkways or roads in the park; however, there is no documentation on the dam’s purpose.
Landscaping techniques, such as drip irrigation and xeriscaping can reduce California's use of water immensely. Eighty Percent of the state’s developed water supply is used on agriculture, but much of that eighty percent is wasted because of sprinkler systems. The water sprayed from sprinkler systems often evaporates, and more water is wasted to water the plants. A drip system is specifically placed at each plant and lets the water seep into the roots, so no water can be wasted through evaporation. This would require less water to be used on plants, because more is actually reaching the roots, saving the rest of the water for California. Xeriscaping is a type of “dry landscaping.” This means that materials and plants, such as native plants, succulents, gravel, and water flowers are used to design a beautiful outdoor space, instead of using grass which consumes an average of about fifty-seven inches of rain per year. Grass needs to be watered frequently, using up California’s water supply, but a dry landscape would use little to no water, benefiting California. Farmers and Homeowners can employ these landscaping techniques to reduce the use of California...
As Jensen points out, farming and industry accounts for the vast majority of total water usage in the world (477). The increasingly scarce resource is a necessary ingredient when growing food. Technology continuously improves to make it easier for farmers to grow crops while using less water. Scientists at the University of Georgia utilize what they term “variable rate irrigation” to let farmers automate the current systems of irrigation to water only the crops that need it (Gies). This is an example of retrofitting current farms, but there is a new way of farming coming to cities that reuses practically all of its water and stakes claim much less acreage in the process. The future of agriculture belongs to vertical and urban farming. These types of farms reduce the use of water, chemicals (such as pesticides, herbicides and fungicides), soil and space (The Economist). These farms are so cutting edge that they are mostly in the experimental stages. Firms like Famgro farms are testing “stackable” farming systems that can scale with demand, even further reducing waste. Famgro’s stackable farms are ideal for cityscapes where land is at a premium; furthermore, reaping the added benefit of being in close proximity to the customers that they serve. Customers will enjoy high quality, fresh produce at only a slightly
Throughout California there is a total of 1,404 dams(KQED). They can be small structures just holding back rivers and streams, or as big as lakes and reservoirs, supplying water to up to 20 different counties. Oroville dam is the largest dam in California and is located just outside of Oroville County near Sacramento.
Farmers and ranchers who own water rights should have their water amount filled earlier in order to facilitate themselves with the proper amount of water. They should not be restricted to a smaller prearranged amount of water each year. Water us...
In order for Scotts Bluff County to maintain these exceptional production rates, several different factors come into play for contributing to the successful outcome of the crop production in this area. One factor that plays an important role in the production is the amount of water resources that are available in Scotts Bluff County. If farmers are unable to get the quantity of water necessary to grow their crops, the crops will begin to suffer damage, resulting in a lower rate of crop production and profit. Therefore, in ...
Most of water consumed in China is not rationally used. The cause which intensifies the water shortage in China is water inefficient use. For instance, 65%-70% of Chinese water usage is spent on agricultural needs, but more than half of this amount evaporates percolates and loses (Roberts 2009). Besides, majority of another 20%-25% which is occupied by China’s industry is not recycled (Brown 2008a, 16; Roberts 2009). Obviously, improving water distribution technologies and management quality can be one of the options to reduce the water scarcity in China. There are many different methods of improving the water distribution efficiency. Firstly, irrigation technologies should be improved. Farmers in China may use drip and shrink irrigation methods instead of traditional “surface” ones such as furrow and flood irrigation. Drip irrigation method is used mostly in arid and semi-arid zones and it increases the efficiency of irrigation by transporting the water directly to the roots of irrigated plant. The emitters sprinkle the soil under the roots with water which is introduced to the plant by pipes, diminishing water evaporation, deep percolation and leak. In contrast, fur...
... upon solution to water access disagreements, social and political powers must be willing to compromise since the risks associated with disagreements regarding water allocation may be too great. As stated by Shiyyab (2004), “If sustained over a period of time, these problems will directly affect social harmony, domestic stability and eventually, regional peace.” (p. 30). Investments must be made by industry as well as local and national governments for purification of wastewater so that clean water, when needed, will be available. The necessity of obtaining water is a fundamental human right and,

The Yangtze River is the third largest river in the world, spanning a length of 6,300 kilometers. Construction of this dam would be along a 200 kilometer stretch in the upper reaches of the river known as Three Gorges. The Xiling, Wu, and Qutang Gorges, collectively called the Three Gorges, contain some off the most scenic and beautiful landscape in the world. However, with the construction of the Three Gorges Dam, most of this awe-inspiring scenery would be submerged and lost forever.
Majority of Indian’s livelihoods are dependent upon land and water based occupational functions such as agriculture, animal husbandry, forestry and fisheries. India’s total land is about 329 million hectares, out of which 175 million hectares of land is non-productive hence non-profitable and therefore it requires special treatment for the same reason. In India, water availability situation is murky because of spatial and temporal variability. Both these factors are forecaste...
The lack of water has caused an increased demand in the drilling of wells, which create even more problems with water shortage. “‘ If you own your own property, you can dig a well and you can pump as much groundwater as as you a want…” (Source 3). This shows the problem of over usage of what little water there is. The wells dug at the edge of properties drain and steal water from the surrounding estates. By doing this, you do not know the amount being drained from the aquifer. “‘Groundwater is like a bank account. You can’t take out more than you put in on an ongoing basis,’” (Source 3). The unwatched drainage of water by farmers can empty out an entire aquifer if it is not filled back
One main causes of water scarcity is water mismanagement worldwide. Water mismanagement has become a crisis of governance that will impact heavily ...
Sandra Postel, on the other hand, has a different opinion than Danielle’s. She proposed that “without increasing water productivity in irrigation, major food-producing regions will not have enough water to sustain crop production”.
Water is an integral part of not only human beings but all other creatures in the world. We use it every day for different purposes such as domestic, agricultural and industrial. Water has always been a prestigious resource. However, the majority of people do not appraise water’s worth since they do not face water scarcity; whereas, in third world countries it is one of the most serious problems. Nearly 2.4 billion people have a lack of water resources in the world, shows the investigation done by the Pacific Institute, an Oakland, California-based non-profit scientific research group. Moreover, every year this number is growing gradually and more people are suffering (Bloomberg News, 2010). There are certain causes which deteriorate current situation. The most influential reasons are global warming, pollution by human-beings and overpopulation. It is known that India is one of the countries which face water scarcity so this essay will consider the possible ways of solutions of water shortage in India.
