Whitepaper - Stage-Discharge Rating Curves.

The rate of downloads of the paper “5 Best Practices for Building Better Stage-Discharge Rating Curves” indicates a very high latent demand for guidance on how to develop rating curves. A stage-discharge rating curve represents the relation of water level at a given point in a stream to a corresponding volumetric rate of flow. The shape of a curve can be discovered by conducting synchronized measurements of...

Fracking illustration.

There is no shortage of differing opinions about the hydraulic fracturing ‘fracking’ technique for shale gas extraction. I am impressed at the influence of this technique on global geo-politics. Previously inaccessible hydrocarbon reserves are changing the global distribution of wealth. There is economic incentive to be an early adopter because there is risk that late adopters will have to develop infrastructure when prices are much lower...
