TL;DR: General classes of direct value comparison, coupling real and modelled values, preserving data patterns, indirect metrics based on parameter values, and data transformations are discussed.

TL;DR: An integrated model framework based on a Bayesian network (Bn) is presented, used to assess the sustainability of eight coastal lake-catchment systems, located on the coast of New South Wales (NSW), Australia.

TL;DR: In this paper, the authors evaluated four metrics to define the spatially variable (regionalised) hillslope sediment delivery ratio (HSDR) in a catchment model that accounts for gully and streambank erosion and floodplain deposition.

TL;DR: Some of the limitations and needs of existing road erosion models are revealed, including limitations of their ancestor hillslope erosion models, the imbalance between representation of erosion processes versus sediment delivery, a lack of representation of subsurface flow interception and the lack of model testing and uncertainty analysis.

TL;DR: The authors reviewed knowledge of nitrogen and phosphorus generation from land use and export to waterways, including studies relevant to Australia, and highlighted the importance of dissolved N and P for overland flow and groundwater pathways, for sheep, beef and dairy grazing land use.
