'Disaster' in Maldives as capital suffers water crisis

Posted By Waterlover in Planning and Management

India and Sri Lanka airlifted drinking water to the Maldives after a fire at a desalination plant led to severe shortages and triggered unrest on the streets of the honeymoon islands' capital.

Authorities declared a "disaster situation" after the fire on Thursday led to a drinking water crisis on the main island of Male, one of the world's most densely populated capitals.

Much of the capital was still without drinking water Friday and local media reported that angry residents fought and attacked shops that rationed mineral water, while hotels in Male said supplies were rapidly running o http://www.dailymail.co.uk -

Giant Ancient Roman Water Basin Uncovered

Posted By Waterlover in Miscellaneous

Italian archaeologists have unearthed the largest Roman water basin ever found, right in the heart of modern Rome.

Found some 65 feet down near St. John in Lateran Basilica during the excavation of the new metro C line, the huge irrigation basin measures 115 feet by 230 feet.

“It’s so big that it goes beyond the perimeter of the metro work site. It has not been possible to uncover it completely,” Rossella Rea, the dig’s director, said at a news conference in Rome. http://news.discovery.com -

Characterising performance of environmental models

Posted By Sina in Hydrogeology , Hydrology

In order to use environmental models effectively for management and decision-making, it is vital to establish an appropriate level of confidence in their performance. This paper reviews techniques available across various fields for characterising the performance of environmental models with focus on numerical, graphical and qualitative methods. General classes of direct value comparison, coupling real and modelled values, preserving data patterns, indirect metrics based on parameter values, and data transformations are discussed. In practice environmental modelling requires the use and imple http://www.likbez.com -

Groundwater, the Hidden Resource

Posted By goopsgoops in Hydrology

Water is essential to human, plant, and animal survival. From huge cities to tiny villages, about 50% of the world’s population depends on groundwater every day.
So what’s the problem? Well, while groundwater is the most abundant source of fresh water on earth, it remains a hidden resource. We often know where to locate it, but what really keeps it “hidden” is the limited amount of data on its availability, quantity and quality. In other words: we often have insufficient real insight in the water below.
Now it’s time to uncover the mysteries behind the great resource of groundwater! http://vimeo.com -

Dokan Dam: Irrigation Valve Opened for 30 Cumecs (VIDEO)

Posted By teddyRIO in Fluid Mechanics

The Dokan Dam is a multi-purpose concrete arch dam abutted by gravity monoliths. It is 360 metres (1,180 ft) long and 116.5 metres (382 ft) high. At its base it is 32.5 metres (107 ft) wide, tapering off to 6.2 metres (20 ft) at the top. The combined maximum discharge of the dam is 4,300 cubic metres (150,000 cu ft) per second. This is divided over a spillway tunnel with three radial gates having a combined maximum discharge of 2,440 cubic metres (86,000 cu ft) per second, and an emergency bellmouth gloryhole spillway with a capacity of 1,860 cubic metres (66,000 cu ft) per second.
