What factors impact water availability and daily water use?
Factors that can affect per capita water include: Rainfall, temperature and evaporation rates – Precipitation and temperature varies widely across the state. Areas with high temperature and low rainfall need to use more water to maintain outdoor landscaping.
What are the factors affecting water quality and availability?
Water quality is influenced by many factors like precipitation, climate, soil type, vegetation, geology, flow conditions, ground water and human activities . The greatest threat to water quality is posed by point sources of industries and municipalities.
What are the 6 main indicators of water quality?
Scientists measure a variety of properties to determine water quality. These include temperature, acidity (pH), dissolved solids (specific conductance), particulate matter (turbidity), dissolved oxygen, hardness and suspended sediment .
What are 3 causes of water pollution?

- Marine Dumping. ...
- Sewage and Wastewater. ...
- Oil Leaks and Spills. ...
- Agriculture. ...
- Global Warming. ...
- Radioactive Waste.
How do humans affect water availability?
Humans directly change the dynamics of the water cycle through dams constructed for water storage , and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.
How does topography affect water availability?
Topographic shape is a watershed attribute thought to influence the flow path followed by water as it traverses a catchment . ... These results suggest that during high flow periods, both the average stream acidity and the magnitude of fluctuations in H + are conditioned by the topographic shape of the catchment.
What process would increase availability of freshwater?
As warmer temperatures increase the demand for water, the amount of freshwater available may decline and increase competition for water resources in some areas.
What are the 5 main indicators of water quality?
They include dissolved oxygen, pH, temperature, salinity and nutrients (nitrogen and phosphorus) .
What are the 5 indicators of water quality fresh water )?
They include stream flow, dissolved oxygen and biochemical oxygen demand, temperature, pH, turbidity, phosphorus, nitrates, total solids, conductivity, total alkalinity, and fecal bacteria .
What factors contribute to poor water quality?
Anthropogenic factors affecting water quality include impacts due to agriculture , use of fertilizers, manures and pesticides, animal husbandry activities, inefficient irrigation practices, deforestation of woods, aquaculture, pollution due to industrial effluents and domestic sewage, mining, and recreational activities ...
What are the 10 effects of water pollution?

What would happen if we ran out of water?
For Earth as a planet, running out of water has some serious consequences. ... Environmental scientists predict that as well as sinking terrain over extraction of groundwater could also lead to an increased risk of earthquakes due to the fact that the Earth’s crust is becoming lighter.
Will we run out of freshwater?
While our planet as a whole may never run out of water , it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. ... Also, every drop of water that we use continues through the water cycle.
