Short summary
Water management faces the challenge of non-stationarity in future flows. To extend flow datasets beyond the gauging data, this study presents a method of generating an ensemble of weekly flows from tree-ring reconstructed flows to represent uncertainty that can overcome certain long-standing data challenges with paleo-reconstruction. An ensemble of 500 flow time series were generated for the four sub-basins of the Saskatchewan River basin, Canada, for the period 1600–2001.

The paper investigates the use of GIS to come up with model parameters. This is part of a process of simplifying model use. The findings show that existing GIS data can be used for estimating model parameters as the outcomes of the research show that model outputs are consistent with previously estimated measures. This research is part of a development of a model which can estimate soil loss and sediment delivery at broad spatial and temporal scales to improve catchment management.

Short summary
WQSAM is a water quality model designed specifically for South Africa as it relies on flow data generated by South African-specific flow models. However, many of the characteristics of WQSAM would make it suitable for other developing semi-arid countries. This study attempted to adapt WQSAM to take in flow data from the globally-applied WEAP flow model so that WQSAM can be applied elsewhere. WQSAM could effectively use the flow data from the WEAP model as demonstrated on a case-study catchment.
