William R. Selbig, Michael N. Fienen, Judy A. Horwatich, Roger T. Bannerman
2016, Water (8)
An urban pollutant loading model was used to demonstrate how incorrect assumptions on the particle size distribution (PSD) in urban runoff can alter the design characteristics of stormwater control measures (SCMs) used to remove solids in stormwater. Field-measured PSD, although highly variable, is generally coarser than the widely-accepted PSD characterized...
Ca, Sr and Ba stable isotopes reveal the fate of soil nutrients along a tropical climosequence
Thomas D. Bullen, Oliver A. Chadwick
2016, Chemical Geology (422) 25-45
Nutrient biolifting is an important pedogenic process in which plant roots obtain inorganic nutrients such as phosphorus (P) and calcium (Ca) from minerals at depth and concentrate those nutrients at the surface. Here we use soil chemistry and stable isotopes of the alkaline earth elements Ca, strontium (Sr) and barium...
