Enhancing stormwater control measures using real-time control technology: a review.

Xu, W. D., Burns, M. J., Cherqui, F., & Fletcher, T. D. (2021). Urban Water Journal, 18(2), 101-114.

This paper reviews the application of Real-Time Control (RTC) applied to different types of SCMs at a range of scales, revealing both the benefits and challenges. The first part discusses how RTC could enhance the hydrologic performance of different types of SCMs. The second part investigates the potential of RTC technology to play a major role at larger scales, by operating a range of distributed small-scale systems as a coordinated system.

The paper concludes that use of RTC technology has the real potential to improve current
urban water management and overcome existing barriers. RTC can improve the performance of various type of SCMs at the site scale, in terms of both runoff quality and quantity. There is
also an untested potential to tackle the mix of scales, where RTC could gather the decentralised small-scale systems into a virtually connected network, achieving much greater control of urban runoff at catchment scale.

Longer duration flooding reduces the growth and sexual reproductive efforts of a keystone wetland tree species.

Greet, J., Fischer, S., & Russell, K. (2020). Wetlands Ecology and Management, 28:655-666

This paper surveyed 140 Eucalyptus camphora (Mountain Swamp Gum) trees across a swamp forest in both 2012 and 2019. Using TUFLOW to model daily water levels for the period from 2009 to 2019, it determined the flooding history for each surveyed tree and then assessed the effect of flooding duration and tree size on the survival, growth, condition and extent of sexual reproduction of individual trees.

The paper concludes that longer flooding durations limited the basal area growth of larger trees and reduced extent of sexual reproduction. Larger trees had greater basal area growth and signs of sexual reproduction overall. There were no clear effects of flooding duration or tree size on survival or condition. Its suggests that for flood-tolerant tree species, prolonged (but not chronic) flooding is likely to result in slower-growing smaller trees potentially without impacts on condition or survival, and that slow tree growth and vegetative regeneration are important strategies for persistence in swamps.

Catchment-scale urbanization diminishes effects of habitat complexity on instream macroinvertebrate assemblages.

White, J.Y. and Walsh, C.J. (2020). Ecological Applications, 30(8).

This paper experimentally assessed the effect ofincreased surface complexity in wood, the dominant hard substrate in our 18 study reaches on14 small streams, on in-stream macroinvertebrate assemblages across a range of urban impact.

The paper found that increased surface complexity increased abundance of most taxa, but this effect was less pro-nounced in urban streams, partly because of the reduced species pool tolerant of urbanstormwater impacts, and partly because of a lesser response of some species to increased complexity in more urban streams. The result suggest that restoration of habitat complexity in streams without catchment-scaledrivers of degradation is likely to have small, positive benefits to in-stream biotic assemblages, but the efficacy of such approaches in catchments subject to urbanstormwater runoff will be greatly diminished. For streams of urban catchments, restoration activities should first be aimed at controlling the larger-scaleproblem, which is typically the altered water quality,reduced base flows, and increased intensity and frequency of storm-flows caused by urban stormwater runoff.

How urban stormwater regimes drive geomorphic degradation of receiving streams.

Russell, K. L., Vietz, G. J., & Fletcher, T. D. (2020). Progress in Physical Geography: Earth and Environment, 44(5), 746-778.

This paper computed sand and gravel bed sediment transport capacity for nine streams in catchments covering a gradient of urbanisation. It compared transport capacity distributions and cumulative transport capacity over one-year between the streams.

The paper found: 1) Cumulative transport capacity increased greatly with urbanisation which was driven primarily
by flow regime change; 2) Transport capacity exceeded measured bedload transport by factors of 50 to 350 in the urban streams, indicating high levels of available stream energy beyond what was used for transport; 3) The effect of hydrology alone accounted for the vast majority of the increase in transport capacity and is therefore the key driver of degradation in urban streams; and 4) Flow mitigation should be the priority of any urban stream restoration project
