Dynamics of sediment and nutrient fluxes from burnt forest catchments

Final Report for Land and Water Australia Project DSE1, and Victorian Department of Sustainability and Environment Project

The magnitude of the impact of wildfire on water quality in SE Australia has rarely been estimated because the location and timing of wildfires is unpredictable, usually precluding the establishment of robust before and after impact experimental designs.  However the 2003 Alpine fires presented a rare opportunity to overcome this constraint when two long-term water quality research catchments were burnt by wildfire. The combination of a sound experimental design and (more)...

Polyacrylamides in Irrigated Agriculture

Polyacrylamide (PAM) has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. PAM’s soil stabilizing and flocculating properties have also substantially improved runoff water quality by reducing sediments, N, ortho and total P, COD, pesticides, weed seeds, and microorganisms in runoff. The first series of practical field tests of (more)...
