Earth's Water Cycle Is Changing Dramatically, And Much Faster Than We Predicted

"Freshwater cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give us the illusion of certainty. Freshwater will always come from the tap. Won't it?

Unfortunately, that's not guaranteed. Climate change is shifting where the water cycle deposits water on land, with drier areas becoming drier still, and wet areas becoming even wetter."

Software could help to save up to 80 per cent of water used on UAE farms

"The UAE's farmers can now use new software that helps to plan crop planting and also calculate how much water their land will need over a year.

A study carried out over many years to trace the flow of sap in date palm trees showed that farmers are using nearly three times as much water as they need to irrigate their plants.

It found that farmers typically irrigate each tree with about 300 litres of water a day.

However, by measuring the amount of sap flowing in the trunk of a date palm, researchers found they could cut that to 180 litres a day during the summer, and to as little as 60 to 80 litres in winter. This would save up to 80 per cent of the water used on the country's farms."

One Woman’s Mission to Fight Water Scarcity in Africa | Earth.Org - Past | Present | Future

"Dr. Sónia Santos Assunção, an experienced geophysicist with extensive experience in soil assessment, first successfully carried out Geophysical exploration to detect underground water in Ghana in 2016 with the support of Geo Analysis that provided the equipment, and given the straight-forward applicability and efficiency of the technologies she used, she decided to extend her scientific project beyond one country. The geophysicist will soon embark on a one-year journey across the African continent, travelling 24,000km to cross a total of 21 countries – from Cairo to Cape Town and from Cape Town to Tunisia – to evaluate the presence of underground sources of water and to teach locals how to acquire geophysical data (available satellite images and information will be provided by AQUAFUTURE Groundwater consultancy)."

Eight most common impurities observed in water supplied to domestic households

The water supplied to domestic households has many types of contaminants which have the potential to create health irregularities in the consumer family. Among these contaminants, eight most common impurities were identified, and the type of filter which can remove or reduce them was delineated in the figure. Before procuring a water filter remember to see this chart. It will help to understand the impurities that the selected water filter can remove. Any water filters available in the market are generally made of one or more of these filters. To decide wisely use the concepts of MCDM to select your filters. Compare the filters available in the market with respect to Cost, Contaminant Removal Efficiency, Maintenance requirement, and type of filters used and rate each filter based on these factors with the help of AHP or ANP techniques. The result will be the filter that will be most efficient for your use. You can also use the ODM tool to come to a decision regarding the procurement o...

Seven Most Tenable Application of Artificial Intelligence on Water Resource Management Problems

AI or Artificial Intelligence is a pioneering technique that has enabled the creation of intelligent machines. or smart machines which have the power to self adapt based on the situation presented to them. It requires situations whose response is known and based on this training data set it learns the problems which it has to solve when it is ready. Due to the alarming success with AI in robotics, electronics, etc fields the same technique is now used to solve the problems of water resource management. This ppt shows the seven most notable use of AI in water resources-based problems where satisfactory improvement has encouraged the further application of the technique.

How to use the knowledge of hydroinformatics in opening a start up ?

Hydroinformatics based StartUps Hydroinformatics is a branch of informatics that concentrates on the application of information and communications technologies (ICTs) in addressing the increasingly serious problems of the equitable and efficient use of water for many different purposes. Here is a list of the startups which use the knowledge and techniques of hydro informatics to solve real-life problems related to the management of water resources. Before the list let us introduce the concept of Start-Up : "A startup is a young company founded by one or more entrepreneurs to develop a unique product or service and bring it to market. By its nature, the typical startup tends to be a shoestring operation, with initial funding from the founders or their friends and families." There are various water-based Start-Ups that use the concept of hydro informatics,i.e., real-time monitoring(RTM), data analysis, Artificial Intelligence( AI) and Machine Learning(ML), and Internet...
