Computational modelling methods for assessing the risks from lead in drinking water
Computational modelling methods have been used to predict the risks from lead in drinking water across a simulated supply zone, for a range of plumbosolvency conditions and a range of extents of occurrence of houses having a lead pipe, on the basis of five risk benchmarking methods. For the worst case modelled (very high plumbosolvency and 90% houses with a lead pipe) the percentage of houses at ...

Spatial risk-based assessments for climate adaptation using the SimCLIM modelling system: a case study of domestic rainwater harvesting as the sole source of water
This paper describes a software modelling system, SimCLIM, for simulating the effects of climate variability and change, and demonstrates its application to domestic rainwater harvesting (RWH). The paper first describes SimCLIM and then focuses on a case study of the reliability of domestic RWH systems as the sole source of water in South East Queensland, a region of high spatial and temporal ...

An optimization model for water resources allocation risk analysis under uncertainty
In order to deal with the risk of low system stability and unbalanced allocation during water resources management under uncertainties, a risk-averse inexact two-stage stochastic programming model is developed for supporting regional water resources management. Methods of interval-parameter programming and conditional value-at-risk model are introduced into a two-stage stochastic programming ...

Incorporating uncertainty into adaptive, transboundary water challenges: a conceptual design for the Okavango River basin
In this paper, we present a review and conceptual design to integrate hydrological/ecological models, global uncertainty and sensitivity analysis, integrative modelling and decision analysis for complex and adaptive transboundary challenges. The research uses the transboundary issues within the Okavango River basin, a shared water resource among the nations of Angola, Namibia and Botswana, as an ...

World’s 37 Most Water-Stressed Countries
Providing stable freshwater supplies is a priority for every country in the world. Yet stable supplies are increasingly hard to come by in many countries, as water-related risks increase. For example, recent droughts threatened GDP growth in the United States. Monsoon floods killed hundreds and displaced thousands in India. Increased competition for water may impact energy production in China, ...

Dynamic risk assessment model for water quality on projection pursuit cluster
With the aim of reducing the losses from water pollution, a dynamic risk assessment model for water quality is studied in this paper. This model is built on the projection pursuit cluster principle and risk indexes in the complex system, proceeding from the whole structure and its component parts. In this paper, the fuzzy analytic hierarchy process is used to screen out index system and ...

Risk-based integrated management of transboundary water resources: a general framework
Integrated management of transboundary surface waters and groundwater aquifers faces not only difficult problems and uncertainties at a national level, but also problems resulting from the fact that these water bodies cross international borders. After showing the importance of internationally shared waters at the global scale in terms of spatial extension, quantity and water uses, this paper ...
