Between July 2012 and June 2013, over 1000 GL held by the Commonwealth Environmental Water Holder (770 GL) and The Living Murray program (289 GL)-- including return flows from the Victorian rivers — is expected to have been delivered.

It was not possible to deliver the 450GL environmental upwater to South Australia, nor achieve flows at the South Australian border of between 60,000 and 80,000 megalitres (ML) a day, without flooding private property.

Movement of native fish species, particularly golden perch and spangled perch was facilitated by the environmental flow and connection between the Macquarie and Barwon rivers.

In addition to the volume released from Hume Dam, return flows and the Commonwealth's 151 GL of held South Australian allocation were delivered directly to the South Australian border to meet environmental demands in the Lower River Murray, particularly for maintaining connectivity between the Lower Lakes and Coorong, and provide suitable habitat conditions (both salinity and water levels) in the Coorong for estuarine fish and vegetation species.

Environmental water was delivered between January and February to manage the recession from high natural flows during late December / early January and ensure that river levels decreased gradually.

In addition to this volume released from Hume Dam and the volume approved for the Coorong, return flows and the Commonwealth's 134 GL of held South Australian allocation were delivered directly to the South Australian border for meeting environmental demands in the Lower River Murray, particularly for maintaining connectivity between the Lower Lakes Coorong and providing suitable habitat conditions (salinity and water levels) in the Coorong for estuarine fish and vegetation species.

Connectivity between the lower Macquarie and Barwon rivers can be successfully achieved using environmental water, particularly in synchrony with flow events occurring in the Barwon River.

Up to 500 ML of Commonwealth environmental water has been made available to provide flows to Johnson's Waterhole between August 2013 and June 2016.

Between 6 August and 17 October 2015, 12,114 ML of Commonwealth environmental water was delivered in conjunction with 40,440 ML of NSW environmental water to provide two flow pulses to the Northern and Southern Macquarie Marshes.

In years of relatively low flow, changes in weir pool levels in conjunction with environmental water use can confer ecological benefits between the river and floodplain, such as nutrient exchange and wetting of fringing vegetation.

Commonwealth environmental water provided 100 per cent of flows over the barrages between September 2015 and June 2016 into the Coorong.

00.00 - 00.12 News reader: A new agreement between the State and Commonwealth will see extra environmental water flow to the wetlands along the River Murray.

Using an interdisciplinary approach that combined evidence from climate modelling of large 20th - century eruptions, annual measurements of Nile summer flood heights from the Islamic Nilometer — the longest - known human record of environmental variability — between 622 and 1902, as well as descriptions of Nile flood quality in ancient papyri and inscriptions from the Ptolemaic era, the authors show how large volcanic eruptions impacted on Nile river flow, reducing the height of the agriculturally - critical summer flood.

«The ability of WaterFALL to simulate water flows within individual, small segments of rivers and streams was pivotal in enabling the study team to develop statistically significant correlations between changes in streamflow and biological diversity and richness at each of the locations where biological inventories had been prepared by the North Carolina Department of Environmental Quality,» said Michele Eddy, lead developer of the WaterFALL ® model and member of RTI's study team.

For example, intra-strain cooperative behaviors are more likely to be evolutionarily stable when different cell lineages are segregated in space, with typical interaction distances between cells being strongly influenced by the diffusivity of secreted products, biofilm architecture, and environmental flow conditions [16 — 19].

Gene flow between the two species can also cause ecological and environmental problems, especially if the introduced trait provides an adaptive advantage to the progeny such as disease or insect resistance, Bagavathiannan said.
