Key Points Brune and Churchill curves poorly predict reservoir trapping in tropical rivers A modification to the curve shows promise better The partitioning of particle size fractions through reservoirs are highlighted
The pH is one of the fundamental soil properties governing nutrient availability, metal mobility, elemental toxicity, microbial activity, and plant growth. field topsoil (0–0.10 m depth) subsoil (~0.60–0.80 was measured on floodplain soils collected near outlet 1186 catchments covering >6 Mkm2 (6 × 1012 m2) or ~80% Australia. Field duplicate data, obtained at 124 randomly selected sites, indicate a precision 0.5 unit (or 7%), mapped patterns are consistent meaningful. median 6.5, while...
The National Geochemical Survey of Australia (NGSA) was carried out to bridge a vast knowledge gap about the concentration and distribution chemical elements at Earth’s surface in consequent poor understanding processes controlling their here. aim project contribute improving exploration for energy mineral resources through pre-competitive delivery new spatial layer compositional data information. Surface (0–10 cm depth) shallow ( c . 60–80 cm) samples catchment outlet sediments were...
Abstract The conservation profession is increasingly seeking effective ways to reduce societal impact on biodiversity, including through targeted behavior change interventions. Multiple programs exist, but there also great uncertainty regarding which behaviors are most strategic target. Behavioral prioritization a tool that has been used effectively support decision‐making in other environmental disciplines and more recently for small sub‐set of biodiversity challenges. Here, we use...
High turbidity in reservoirs may negatively affect aquatic ecology and water infrastructure. Although many are turbid, the origin intra- interannual variability of is not well understood. To examine cause turbidity, we measured concentration, particle size, organic content mineralogy suspended benthic sediment samples from Lake Dalrymple, a large reservoir northern dry tropical Queensland. Samples were collected during season (May–November) 2004, 2005, 2006 2011. Water turbid (>45...
