Water Quality Diffuse Pollution and Watershed Management Handbook: A Practical Guide to Stormwater Runoff, Nutrient Loading, Catchment Protection

Why does a stream still fail its standards after fifteen years of practice work? Why do two consultants hand you load estimates that differ by a factor of three, using the same data? Diffuse pollution is not hard because the science is obscure. It is hard because the load arrives in a handful of storms, the sources are invisible on a land use map, and the arithmetic everyone trusts quietly overstates what a programme can deliver. Inside, you will gain the ability to: - Walk into an unfamiliar catchment and know within one field season where the load is coming from, instead of spending three years finding out- Defend your load estimate when a reviewer challenges it, and catch the errors buried in someone else's numbers before you put your name to them- Stop funding measures that cannot physically remove the pollutant you are listed for, and redirect that money to something that can- Size a basin, a bioretention cell, or an infiltration trench to a procedure that passes review the first time- Look at an eroding bank and know whether a treatment will hold or be undermined within four winters- Commit to a reduction figure your programme will actually achieve, so you are funded for a second decade instead of reported as a failure >Scroll up and get your copy today.
