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.

That Sinking Feeling: Rising Sea Level Isn't Cities' Only Water Worry

Posted By Ryan13 in Fluid Mechanics , Hydrogeology , Planning and Management

Some of the world’s expanding coastal cities face a two-pronged threat involving water: Sticking giant straws into the ground to suck up freshwater can cause the ground below to sink at the same time that sea levels are rising.

That interplay between subsiding land and rising seas highlights an underappreciated risk in global climate change, according to scientists.

It’s not known how many people live on coastal lands that are sinking due to excessive groundwater pumping, but about 150 million live within 3.3 feet of today's high-tide mark. And the worst-case scenario for sea level rise by the end of this century is nearly six feet, according to a recent study. http://www.nbcnews.com -

Where Catastrophic Droughts and Floods Are Bound to Happen in the U.S.

Posted By Hadian in Fluid Mechanics

Many Americans might not realize it, but the country is headed for a brutal reality check in terms of access to clean, cheap water. Climate change's amplifying effects are turning dry regions into virtual deserts and wet ones into flood zones, setting the stage for a horde of "water-related catastrophes, including extreme flooding, drought, and groundwater depletion," warn scientists at UC Irvine http://www.theatlanticcities.com -

Typhoon Haiyan: Thousands feared dead in Philippines

Posted By tarantino in Fluid Mechanics

1) What is the story?

Typhoon Haiyan, one of the largest tropical cyclones ever recorded, struck the Phillipines, Vietnam and Southern China. High winds (235km/hr) and torrential rain (up to 400mm in some areas) have led to flooding, landslides and structural collapse. Thousands are feared dead.

2) Why is it important?

This storm is responsible for a significant loss of lives. Hydrologis http://www.bbc.co.uk -

According to the EPA of the United States at least 36 states have experienced water shortage issues. The price of water has increase by significant amounts. The price of water in some states have increased by over 35 percent over the past two years.
This is very important that not only do countries in the third world experience water shortage problems but the problem is much closer to home. http://www.environmentalleader.com -
