Challenges In The Simultaneous Development And Deployment Of A Large Integrated Modelling System, Matthew Paul Stenson, Peter Fitch, Dave Penton, Jamie Vleeshouwer, Ben Leighton, Jean-Michel Perraud, Garth Warren, Daniel Collins

International Conference on Hydroinformatics

Many of our natural resource management issues cannot be adequately informed by a single discipline or sub-discipline, and require an integration of information from multiple natural and human systems. As we are unable to observe and monitor more than a few important indicators there is a strong reliance on supplementing observed information with modelled information. Following a period of record drought in the 1990’s, the Australian government recognised the need for better quality, more integrated, and nationally consistent water information. The Australian Water Resources Assessment system (AWRA) is an integrated hydrological modelling system developed by CSIRO and Australian Bureau of …

International Conference on Hydroinformatics

The objective of this study is to compare the sustainability of current water systems when a dual water distribution system (WDS) is used for the non-potable water purposes of fire protection, irrigation, and toilet flushing. Sustainability of urban WDS is evaluated in terms of hydraulic efficiency and water quality. The first step is to assess sustainability of an example urban WDS by using sustainability index (SI). The SI is measured by reliability, resiliency, and vulnerability performance indices. Pressure and water age are selected as main parameters to determine sustainability. Once the SIs for pressure and water age are calculated by …

International Conference on Hydroinformatics

Integrated urban water systems (IUWSs) generally comprise the components related to both water supply and waste water systems. These components are subject to uncertainty in terms of operation, management and information. Hence, assessment of strategies in the IUWSs over the planning horizon should include such a risk analysis of these uncertainties. Owning to the complexity of these risks, a comprehensive risk assessment tool needs to be developed. In this paper, a risk assessment tool is presented to support the evaluation of intervention strategies in an IUWS over a planning horizon. The IUWS is modelled by “WaterMet2” which is a simulation, …

International Conference on Hydroinformatics

In arid regions, groundwater is the most reliable source for freshwater. Thus, ensuring an aquifer’s long-term stability is one of the fundamental tasks for nowadays groundwater management. Especially in agriculturally used coastal regions, where water consumption exceeds annual recharge, water table drawdown and subsequent saline intrusion are problems that need to be addressed. Wihin the context of the government-funded research project „International Water ResearchAlliance Saxony“, groundwater quality for near-coastal, agriculturally used areas was investigated under the influence of marine saltwater intrusion. In the study region’s near-coastal areas, agricultural development increased tremendously during recent decades, while a steady lowering of the …

Flash Flood Simulation Using Geomorphic Unit Hydrograph Method: Case Study Of Headwater Catchment Of Xiapu River Basin, China, Dawei Zhang, Jin Quan, Fan Wang, Xiaoyan He

International Conference on Hydroinformatics

The flash flood refers to flood produced by heavy local rainfalls and often occurs in mountainous areas. It is characterized by a quick rise of water level causing a great threat to the lives of those exposed. Many countries and regions face the threat of flash floods. However, some traditional hydrological models can hardly simulate the flash flood process well due to the lack of hydrological data and the insufficient understanding of complicated runoff mechanism in mountainous and hilly areas. According to this condition, a new hydrological model based on the framework of Xinanjiang model, widely used in humid and …

A Cascade Of Models To Guide Reservoir Operations: Application On The Deadwood River System, Idaho, Usa, Andrew W. Tranmer, Daniele Tonina, Peter Goodwin, Rohan Benjankar, Matthew G. Tiedemann, Paul Woods

International Conference on Hydroinformatics

Adaptive management strategies are increasingly being used by resource managers to optimize complex water delivery systems at the scale of entire watersheds. A variety of models have been proposed to evaluate systems in a piecemeal approach that often times operate at different spatial and temporal scales and prove difficult to integrate with associated field data. In the Deadwood River system of Central Idaho, a series of cascading models was utilized to examine potential impacts of reservoir operations on endangered resident bull trout. Results from integrating limnologic, temperature, nutrient, hyporheic, and hydraulic models show that reservoir operations must remain dynamic depending …
