Introduction of TOPIC

Water = Fundamental human need. 🙁 Demand supply doesn’t match!

Potential for local and international conflict is

Future water supply is in doubt due to unsustainable use and climate change.

Vulnerable population = suffer most!

The Hydrological Cycle

Closed system –> goes round and round, never any more or less in the system.

Water Crisis:

* Amount of water in world is limited. No infinite supply!

* Water = 2/3 of earth’s surface. Most too salty = unusable.

* 2.5% not salty but unreachable (in glaciers and ice caps) Fresh water – 20% in remote areas and rest comes as flood water.

* Next 2 decades usage will by 40%

* 70% used in agriculture. 2020 need 17% more to feed the world.

* 1 in 5 worldwide cant access drinking water

* High child death due to hunger or diseases.

Reasons for the water crisis:

1. Growing population

2. Desire for better living standards

3. Inefficiency of water use

Solutions:

1. Irrigation systems, drip water into plants & precision sprinklers.

2. Plant less water intensive crops.

Human interference affecting water cycle:

* Salinisation –> more water being pumped up, salt leaking in (over abstraction water quality )

* Building of dams affects run off, upstream lots of water downstream not so much due to it evaporating.

* Urbanisation, build more houses surface area, depletion of ground water.

* Evapotranspiration, deforestation stops this process. Chopping down trees could mean larger surface area for run of, water scarcity takes place.

* Cloud seeding (making own rain, acidity ruins quality)

* Transferring water, more water in one area less in another.

Where is all the water?

97.5% = Ocean water 2.5% = Fresh water 0.4% = Surface & Atmospheric water

Groundwater:

> Most rainfall soaks into soil, some further into he ground (infiltration)

Trickles downwards into rocks and becomes groundwater.

> Groundwater is vital in supporting wetlands and stream flows.

> Water table = level at which the rock has become saturated. An aquifer is water

bearing rocks that are saturated.

Water supply is controlled by climate factors!!

Water supply is a balance between precipitation totals and evapotranspiration potentials and is controlled by aquifers.

Water pollution!

2 types:

Water Bourne = Typhoid and Cholera -> oral face contamination due to lack of sanitation

Water washed diseases: = Scarce water (drinking and cooking) 1st demand

Washing (leprosy) and Irrigation (luxury) 2nd demand

Mosquitoes –> malaria, dengue fever, river blindness (water is a breeding ground)

Not just about quantity but the quality of water!

Ground water = pollution less obvious than surface water –> aquifers become polluted, feed surface water = Salinisation due to over abstraction.

Salinisation = the process whereby soluble salts accumulate within the soil.

”Dilutions is the solution to pollution!”

With over 8 billion people on the planet, disposing of sewage waste is a major problem. In developing countries, many people still lack clean water and basic sanitation (hygienic toilet facilities). Sewage disposal affects people’s immediate environments and leads to water-related illnesses such as diarrhoea

However in theory Sewage = natural substance that can be broken down harmlessly in the environment. (It contains all kinds of chemicals e.g. pharmaceutical) 🙁 people are sick virus is in the sewage and can become air Bourne in environment, can catch cholera etc from rivers and seas.

Nutrients…

Sewage can be a fertiliser–> returns important nutrients back to environment. Chemical fertilizers used by farmers also add nutrients to the soil… HOWEVER –>

1. Drains into rivers and seas adds to fertilizing effects of sewage

2. Growth of algae or plankton, takes up oxygen –> takes o2 from water which kills other life forms!

Thermal pollution….

Factories releasing cooling water into rivers…

Salinisation of groundwater –>

Deeper the well, more water being pumped up collects more salt water quality.

Cone of exhaustion –>

Build the biggest well, getting all the water everyone else’s dries up. Sell water to others leads to economic scarcity!

Deepor Beel

* Permanent fresh water lake in the former channel of the Brahmaputra River.

* South of the main river.

* South west of Guwahati city.

* It is a large natural wetland having great biological and environmental importance.

* It’s the only water storage basin for the city.

* Agricultural activates and farmers depend on the water lake.

* Designated as a ramsar site (conservation of the land)

Deepor Beel is on a flood plain –> when it floods water can flow into it.

Toxico, Ecuador

One of the most diverse regions in the world.

3 distinct regions (minus Galapagos):-

1. El Oriente –> Amazon part of rainforest in the east.

2. La Costa –> Western Pacific coast.

3. La Sierra –> Andes Mountains, centre of country.

Operations up to 1992, Texaco spilled 17 million gallons of oil from pipeline and dumped 18 million gallons directly into the rainforest, contaminating 1,700 square miles leaving extremely dangerous conditions.

Oil was dumped into pits around the jungle, water spread into the rivers. Soil and rivers are so polluted that nothing grows, fish are all dying and drinking water is now poisoned.

Vitamin C water-soluble

Vitamin C is a water-soluble vitamin that is naturally found in citrus fruits, tomatoes, and leafy green vegetables. It is a well known fact that Vitamin C is extremely vital in the human diet. Vitamin C is known for its numerous health benefits such as prevention against immune system deficiencies, eye diseases, skin wrinkling and much more. It was discovered that scurvy is primarily caused by a deficiency of this vitamin. The needs of Vitamin-C vary per person but the RDA (Recommended Daily Allowance) for Vitamin-C put forward by the Food and Nutrition Board of the National Research Counsel is 60 mg/day for adults and an additional 20 mg/day is recommended for pregnant women. Women who are lactating are strongly advised to take an additional 40 mg/day so that adequate of the vitamin will be present in the breast milk. Due to the unstable nature of ascorbic acid, it oxidizes...

Drainage and Dewatering

In the saturated soil mass, the process of withdrawl of superfluous water from it whether in natural or any artificial form is referred as drainage. Before any kinds of engineering works for example excavation for basement of foundation for any structure or for foundations of dams, mining projects etc., excavations are widely popular below the ground water level. To perform such kinds of excavations, the ground water has to be lowered to the lowest point of excavation in order to obtain workable dry place for the construction work. In this process, drainage is also an essential part of it in order to decrease pore water pressure and minimize the seepage effect which certainly betters the strength and effective strength of it as well as increases safety and formulates stable excavation. So it can be extracted that generally in waterlogged areas, drainage helps for lowering the water table and enables to...

Water molecule structure

The water molecule itself is comprised of a single oxygen atom and two hydrogen atoms. It is the attractions between these atoms however that give water one of its most important features. Whilst covalent bonds do form to keep the three atoms together, their proximity to one another leads to an uneven arrangement of electrons. This leads to the two hydrogen ends becoming slightly positively charged, with the oxygen atom becoming slightly negatively charged. The difference in charge means that water is described as a dipolar molecule. Water’s polarity, when combined with its abundance, means that it is often described as the ‘universal solvent’. With the exception of non-polar molecules, all polar and ionic substances will form weak hydrogen bonds with water molecules, thus forming a solution. This is important as many of the chemical reactions which take place within both plant and animal cells use water as a solvent....
