population growth. Due to the larger amount of population growth, it is causing the resources to become very scarce. Not only do humans need water for basic needs, we need water for agricultural purposes. For agriculture, freshwater is used for the irrigation of crops and to feed the animals. With agriculture it is possible that they suffer from a shortage of water because of the amount of water that is used for this purpose. “The aim of water harvesting is to mitigate the effects of water…

Dam is an important way of water-resources utilization in large rivers. Dam construction has played significant roles in flood control, irrigation, navigation, and energy supply; however, the enormous negative effects, such as landslides, ecological problems, and water quality decline, could surpass positive gains. In these days, the water has become the most important need of everyone. In the monsoon season, there is over amount of water. Because of no facility of storage of water, this amount…

4.1.1 Particulate control. Particulate can be defined or referred to as tiny particles of matter like dust, smoke, soot which are being emitted during agricultural and industrial processes as well as other economic activities. Various methods involved with particulate control operate basic principles. Solid particulate particles are usually isolated from gases where they are controlled by physical procedures like through a settling chamber. Settling chamber is a wide and elongated pipe where…

Wouldn’t it be neat if we lived in a world where you could wave a magic wand and say, “Aguamenti” and however much water you wanted or needed at the time, suddenly appeared like in Harry Potter? Unfortunately, in reality, water is not so easy to come by. Even though our planet Earth is covered in 70% water, there is not enough spring water from lakes or streams as well as ground water from wells to supply humans, plant life and animals in this ever-growing world…

Fig. 14. The viaduct bridge takes large area of cultivated land in Yang Po Village of Qian Yang County 3.6. Village infrastructure is backward, the internal function does not satisfy the modern life With the improvement of people’s living standard, residents who living the gully region of the Loess Plateau own more requirements for their life. However the original cave dwellings cannot meet their requirements due to the backward infrastructure, such as communication, water supply, power supply,…

Infiltration investigation Introduction Infiltration is the process by which water on the ground surface enters the soil. The infiltration rate is the velocity or speed at which water enters into the soil. It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. On the 2nd of October, we were split into groups and we had to do an infiltration investigation. The experiment was set out to find out whether the infiltrations rate throughout the school were…

consequently, its yield and quality. In India, however, rainfall is notoriously capricious, causing floods and droughts alternately. Its frequency distribution and amount are not in accordance with the needs of the crops. Artificial water supply through irrigation on one occasion, and the removal of excess water…

5.2.6 Liquidity Liquidity is the amount of cash available for farm production at the start of the simulation period. It is required for a variety of activities, such as covering the costs of the inputs for cropping (e.g. fertilizer, herbicides), hiring additional labor and hiring labor to clear forest. In the survey households were asked about their monetary savings and cash, however no answers were provided by the respondents. Therefore, the credit limit is used as a proxy to quantify cash…
