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. -

Why I’m marching: Irish water protesters speak

Posted By Ryan13 in Planning and Management , Miscellaneous

Demonstrators explain their views and why they are taking to the streets:

“This protest is not about water charges. We pay water charges already. This protest is about Irish Water."

“I have concerns about the health risks associated with radiation from the smart meters but as well as that there is no way I am paying for dirty water and the water is still bad up where we are.”

“I know the Government have backtracked but I can’t afford to pay for water and I’m not going to pay for water when Irish Water is going to be privatised."

“Our water is not for sale and I will not be supporting a private company and I have no intention of giving them my PPS number.” -

South Africa’s looming water disaster

Posted By aqua in Planning and Management

As load shedding strikes, and South Africans bemoan the country's power woes, an even bigger worry lurks ominously. If government doesn't spend 100 times more to secure the water supply, South Africa is in huge trouble.

In more than half of the country, South Africans are using more water than what’s available. They are already using 98% of their available water supply, and 40% of their wastewater treatment is in a “critical state”.

A staggering 37% of South Africa's clean, drinkable water is being lost through inefficient ways of using water such as leaking pipes, dripping taps – and that is what’s being reported, the figure could be much higher. -

Ireland: Delay water bills till Government finds charges solution, says the Labour parliamentary party chairman

Posted By aqua in Planning and Management

Bills for water charges should be “put on hold” until a Government committee takes a proper look at Irish Water and brings forward a comprehensive solution to the controversy, according to Labour parliamentary party chairman Jack Wall.

Mr Wall said there was no logic in putting a “sticking plaster” on the controversy and issuing “bills here and bills there”. But he said the PPS number was not a big issue in his constituency. -

Water transfer as a solution to water shortage: A fix that can Backfire

Posted By Kaveh in Hydrology , Planning and Management

Zayandeh-Rud River Basin is one of the most important basins in central Iran, which has been continually challenged by water stress during the past 60 years. Traditionally, a supply-oriented management scheme has been prescribed as a reliable solution to water shortage problems in the basin, resulting in a number of water transfer projects that have more than doubled the natural flow of the river. The main objective of this study is to evaluate the reliability of inter-basin water transfer to meet the growing water demand in Zayandeh-Rud River Basin. A system dynamics model is developed to capture the interrelationships between different sub-systems of the river basin, namely the hydrologic, socioeconomic, and agricultural sub-systems. Results from simulating a range of possible policy options for resolving water shortage problems indicate that water is essentially the development engine of the system. Therefore, supplying more water to the basin without considering the dynamics of the interrelated problems will eventually lead to increased water demand. It is demonstrated that the Zayandeh-Rud River Basin management system has characteristics of the “Fixes that Backfire” system archetype, in which inter-basin water transfer is an inadequate water management policy, causing significant unintended side-effects. A comprehensive solution to the problem includes several policy options that simultaneously control the dynamics of the system, minimizing the risk of unintended consequences. In particular, policy makers should consider minimizing agricultural water demand through changing crop patterns as an effective policy solution for the basin’s water problems. -

An interactive map of 50,000 water rights held in California

Posted By goopsgoops in Planning and Management , Miscellaneous

A water right is a granted permission to withdraw water from a river, stream, or ground water source for a "reasonable" and "beneficial" use.

Currently, water rights holders claim they divert in aggregate approximately 250 million acre feet of water each year.

California receives 71 million acre feet yearly from rain. (200 MAFY before evaporation) -
