TL;DR: Great potential is demonstrated for SfM-MVS to be used as a cost-effective tool to aid in the mapping, modelling and management of hillslope gully systems at different scales, in savanna landscapes and elsewhere.

TL;DR: In this article, the authors investigated linkages between hillslope hydrological connectivity pathways and gully geomorphic change in the Burdekin River Basin using high-resolution (0.1 m) topographic and land cover data derived from low-cost aerial (via unmanned aircraft system) structure-from-motion with multiview stereo photogrammetry (SfM) were used to map fine-scale connectivity patterns and quantify headcut retreat at the hillside scale (~150,000 m2).

TL;DR: In drylands, low annual rainfall and resultant poor ground cover, coupled with high-intensity storms, contribute high sediment loads to receiving waters and significantly degrade landscapes as discussed by the authors. But, as shown in this paper, these sediment loads contribute to flooding.

TL;DR: In this article, the authors compared 15-year records of runoff, sediment and nutrient yields amongst three ephemeral headwater catchments (10.5-13.5 km2) with similar wet/dry tropical climate and landform characteristics, but contrasting cattle grazing pressure.

TL;DR: Good potential for farmers to use DMPP-treated urea as a means of reducing N fertiliser rates without loss of productivity and with less loss of N to the environment is indicated.
