CHAPTER FIVE RESULTS AND DISCUSSIONS
5.1 Concepts of Groundwater Recharge Evaluation
In a broader sense, groundwater recharge is defined by as water that reaches an aquifer from any direction, i.e., down, up, or laterally. In the upper awash catchment, groundwater recharge by downward flow of water through the unsaturated zone is generally the most important mode of recharge. Therefore, groundwater recharge as used in this study refers to the downward flow of water reaching the water table from the unsaturated zone (Freeze and Cherry, 1979; Lerner et al., 1990). When water is supplied to the soil surface, some of the arriving water penetrates the surface and is absorbed into the soil, while some may fail to penetrate

Based on the assumption above, the catchment is water hard to move and no subsurface movement of water towards the defined watershed, to carry out the water balance on long term averaged data equation can be reduced in to:- P= AET+ Ro± ∆S……………………………………… (5.3) R=P-AET-SRO Where, P=1015.77 mm, AET= 710mm, SRO= 139.68 mm R= 1015.77 mm -710mm-139.68mm R= 166.09mm/year
Using the above formula, the recharge of the upper awash catchment is 166.09mm/year which is 16.4% of annual precipitation is recharged. Groundwater recharge evaluated in the Upper Awash catchment takes place in three months (June to August). In contrast in the other month’s groundwater bring about to AET and total runoff, and also this circumstances is caused to be visible by negative value of
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
The Earth is filling in the space where the water once was, causing a reaction known as subsidence, making the ground sink to over a foot in some areas of the central valley. Specifically, around Sack Dam, an important water containment resource, is sinking deeper than all the surrounding area, caused by all the drilling. “Water traditionally flowed with gravity.” Cannon Michael, president of the Bowles Farming Company (Richtel, page 5) stated. “It isn’t going to run uphill.”
In my hometown of Waterdown Ontario, there is rarely a minute when the main downtown area is not buzzing with people. In my opinion, the downtown area of Waterdown is alive and lively. Whether people are shopping in one of the variety of stores, grabbing a bite to eat at one of the numerous restaurants or cafés or just driving through, downtown is easily the focal point of town and continues to increase in chaos as Waterdown continues to grow and suburbanize. In Waterdown, the downtown core is where almost every shop and store is located. If you want to do anything from buy groceries to take a pottery class, you do so downtown.
Today humans have altered our water resource in many different ways. According to a study done in 2004 around 2.7% of water withdrawals are used for around 2,187 facilities for irrigational purposes. Irrigation is usually used for agricultural purposes, including farming. One example of how irrigation has shaped the land is by farmers leveling their fields. Since irrigation uses the natural downhill flow of water, hills may disrupt this flow.
Throughout the centuries, humans have been attempting to find a way to power homes, cars, and other luxuries in the most efficient way possible. Coal and oil were two major sources that begin being exploited during the industrial revolution. Both have caused great controversy over the years from lawsuits to strikes. A new way to drill oil, hydraulic fracturing, was discovered and was an efficient means of drilling until its effects became prevalent. Also, when coal began to run out, a new method called mountaintop removal took hold, but continues to damage the earth.
Runoff, a common problem in many areas, has many causes. These causes, although sometimes avoidable,such as pollution, it can be repaired. As pollution and erosion, two of the main topics in this paper, affect the water quality, the agents aiding the processes are unstoppable. While agents are unstoppable, runoff is still controllable as far as the rate of runoff. When writing a paper such as this, the many information collected is shown in separate paragraphs, corresponding to the ideas.
From: Mr.Jazayeripour the manager of Mojave Desert community to: The California Environmental Protection Agency Water is one of the necessary sources for organisms to survive in many ways. and did you know that (The United States uses about 346,000 million gallons of fresh water every day. allaboutwater.org-water.facts ) Mojave river, colorado river and underground water are the main sources of water for animals, plants, residential, industrial and agricultural uses. ground-water depletion is primarily causes by sustained groundwater pumping.
Report of Sylvia Frey’s Water From the Rock: Black Resistance in a Revolutionary Age Sylvia Frey’s Water from the Rock is meant to convey the deeper meaning of the American Revolution and the determination, line of events and the opportunity for black resistance in America. Frey lays the book out by discussing the economical and geographical differences in America and the effects of this on racial segregation. The pre-Revolution south in America had a highly successful economical basis in slavery.
River has provided protection from flooding but not from the dangers of an inefficient water cycle and a lack of ecological diversity (see figure 2). Pouring concrete into the bed and banks of rivers allows for the water to flow at a much faster rate. The ability for water to infiltrate the ground is non-existent when there is concrete surrounding the water. Without the ability to penetrate the ground, the amount of runoff is increased dramatically. A large decrease in one area of the water cycle only leads to a large increase in another.
Julie is typical twenty-five year-old Hispanic woman that grew up in a household where drinking water from the tap was frowned upon. Now, as an adult, Julie drinks about five water bottles per day, which adds up to 150 water bottles a month, or a grand total of 1,800 water bottles per year. Her water bottle of choice – Dasani Purified Water – costs an average of $4.99 per twenty-four pack, or around $0.20 per bottle, at her local Wal-Mart. This means that Julie, by herself, annually consumes around 74 twenty-four packs of bottled water. In other words, she spends $369.26 on drinking bottled water every year1.
This unusable water usually just sits and sinks back into the ground, poisoning the land around it. This wasted water also sometimes finds other waterholes and merges with them, contaminating them for the people that use that water
Ciera Walton Coursework Ploude 1 Irrigation In Yuma Intro “Describe in detail how irrigation changed Yuma/Southern Arizona?” Irrigation has been a cause in Yuma/Southern Arizona because of the heat, low flow, and the dry deserts. This made irrigation very difficult in 1900s because without water we wouldn’t be able to grow our crops throughout the years, this limited many areas and lands as well. It also makes it very hard to contain and carry out water all across the country.

1. Introduction Water is crucial to our survival! Water is one of the scarcest commodities in the world at the moment; some argue that it is scarcer than oil. Wars have been fought over oil; therefore a war over water is a very big possibility in the years to come on this planet. With the current growth of the world’s population and the increase in demand for water in the agricultural industry, the issue of water scarcity is very likely to get worse and worse (Gupta, 2016).
