Abstract. Effective management of water resources requires that all elements the balance be estimated. Groundwater recharge measurements are difficult, time consuming and expensive. In some cases a field study cannot justified simple empirical relationships used to estimate recharge, often value chosen is simply percentage rainfall. This paper aims use database 4386 based estimates from 172 studies in Australia produce relate nationally available datasets hence can data-poor areas...
Abstract Surface water connectivity between waterbodies in a river–floodplain system is considered one of the key determinants habitat quality, biodiversity and ecological integrity. This manuscript presents results from an investigation into potential changes floodplain inundation wetlands rivers under projected future climates, large river catchment Western Australia. The study was conducted using two‐dimensional hydrodynamic model (MIKE 21), modelling domain included reaches encompassing...
Abstract. The Millennium Drought lasted more than a decade and is notable for causing persistent shifts in the relationship between rainfall runoff many southeastern Australian catchments. Research to date has successfully characterised where when occurred explored relationships with potential drivers, but convincing physical explanation observed changes catchment behaviour still lacking. Originating from large multi-disciplinary workshop, this paper presents evaluates range of hypothesised...
Major restructuring including commercialisation of the water authorities in Australia during past several decades has resulted loss much valuable information on dam infrastructure costs. This paper sets out to provide an Australian perspective costs and cost overruns, examine patterns develop a good predictor overruns for situation. Several metrics, related data, were collated 98 dams constructed across since 1888. Dam costs, operation maintenance (O&M) construction overrun independent...
It has been contended that during the 1997-2008 'Millennium' drought there was an unexpectedly large decline in runoff from some catchments south-eastern Australia (SEA).Potter et al. (2011) suggested across 34 unregulated SEA area weighted reduction streamflow 46 percent.Sixty-five percent of this attributed to annual rainfall and 7 direct or indirect effect changes average maximum temperature.The remaining 28 unexplained residual; potentially due seasonality inter-annual variability...
Many northern Australian rivers have limited or non-existent dry season flow and tend to a series of pools, waterholes, which become particularly important refugial habitat for aquatic biota during the periods between streamflow events. The present study developed techniques identify in-stream waterholes across large inaccessible areas Flinders Gilbert catchments using Landsat imagery. Application this technique 400 scenes 2003 2010 facilitated identification key waterhole refugia that are...
Managed aquifer recharge (MAR) can play an important role in agricultural water management and productivity where suitable aquifers exist. Yet while the benefits costs of surface storage have been extensively reported, MAR under reported poorly conceptualised to date. In this study ten potential schemes wet-dry tropical climates northern Australia estimated levelized ranged from US$0.04 $0.36/m3 for 0.6–5 Mm3/y capacity. The type scheme had largest influence on cost, resulting following...
Small islands provide challenges to hydrological investigation, both in terms of the physical environment and available resources for monitoring. Furthermore, small are generally more vulnerable natural disasters water shortages resident populations. Norfolk Island South–west Pacific, is typical these respects, recent have highlighted lack knowledge required make informed decisions regarding supply. Accordingly, a campaign field measurements analysis was conducted on 2019–2020 period were...
Abstract The majority of the world’s population growth to 2050 is projected occur in tropics. Hence, there a serious need for robust methods undertaking water resource assessments underpin sustainable management tropical regions. This paper describes largest and most comprehensive assessment future impacts runoff undertaken region using conceptual rainfall–runoff models (RRMs). Five RRMs were calibrated data from 115 streamflow gauging stations, model parameters regionalized combination...
Water scarcity in southern Australia and an imperative to develop regional economies have combined renew focus on the potential for irrigated agricultural development Australia’s largely undeveloped sparsely populated north. More than 2 billion dam sites across northern (an area of ~3 million km2) were assessed a consistent objective manner, using DamSite model, largest comprehensive assessment large dams undertaken globally. Simultaneous consideration was given their proximity land...
Population growth and increased irrigation demand have caused a decline in groundwater levels that limit water supply the Darwin rural area. Managed Aquifer Recharge (MAR) is practical solution can be adopted to augment stressed systems subsequently increase security of supply. storage capacity considered primary constraint MAR where unconfined dolostone aquifers rapidly recharge during tropical, wet season drain again dry season. As result, there general understanding this nature full each...
There has been a resurgence of interest in the construction large dams worldwide. This study examined many from around world (>10,000) and compared them to comprehensive dataset developed for Australia (224) provide insights that might otherwise not be apparent examining just one or several dams. The dam datasets (ICOLD ANCOLD) largely confirm existing narratives on Australian construction. Compared Rest World (RoW), were found to: have larger reservoir capacities spillway given catchment...
