Central Valley's growing concern: the mix of oil, water and crops - LA Times

Posted By Kaveh in Hydrogeology , Planning and Management , Water Quality

Here in California's thirsty farm belt, where pumpjacks nod amid neat rows of crops, it's a proposition that seems to make sense: using treated oil field wastewater to irrigate crops. http://www.latimes.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 -

Will the water last in California?

California's 21st century version of the gold rush is a rush for water. As new regulations approach, people are waiting months -- even years -- to get new water wells drilled." http://www.kcra.com -

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 -
