How is water pollution monitored?
Conductivity, salinity, and TDS meters analyze the water quality by measuring the specific electrical conductance of electrolytes dissolved in the water. Though each of these instruments measures a separate parameter, the results are correlated and indicative of pollution.
How can remote sensing be used for water quality monitoring?
Remote sensing provides water quality data with a high spatial and temporal resolution for thousands of lakes at a time. The remote sensing of water quality is limited to the retrieval of water clarity, turbidity, water color, and the concentrations of optically active constituents.
What is the role of GIS in environmental monitoring?
GIS allows better viewing and understanding physical features and the relationships that influence in a given critical environmental condition. Factors, such as steepness of slopes, aspects, and vegetation, can be viewed and overlaid to determine various environmental parameters and impact analysis.
What are the six factors that are used to monitor water quality?
Background. 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 the effects of water pollution?
In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year.
What will happen if water pollution continues?
Water pollution can damage entire food chains. Some health problems water pollution can cause include problems with people’s hearts, liver and kidneys. Also, it can cause diarrhea, cancer, and even cholera. Water pollution can cause many bad effects for people as well as animals.
Which type of remote sensing is used to detect underwater things?
Acoustics is the primary method for remote sensing of the underwater environment because sound can propagate over much greater underwater distances than electromagnetic waves can.
What is the use of remote sensing satellites?
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.
What is the importance of GIS system?
Today a well-developed GIS systems are used to protect the environment. It has become an integrated, well developed and successful tool in disaster management and mitigation. GIS can help with risk management and analysis by displaying which areas are likely to be prone to natural or man-made disasters.
What are the factors affecting water pollution?
The Causes of Water Pollution
- Industrial Waste. Industries and industrial sites across the world are a major contributor to water pollution.
- Marine Dumping.
- Sewage and Wastewater.
- Oil Leaks and Spills.
- Agriculture.
- Global Warming.
- Radioactive Waste.
What is the importance of monitoring do in a water body?
Monitoring provides the objective evidence necessary to make sound decisions on managing water quality today and in the future. Water-quality monitoring is used to alert us to current, ongoing, and emerging problems; to determine com- pliance with drinking water standards, and to protect other bene cial uses of water.
