The European Water Framework Directive (WFD) introduced an integrated perspective in water resources management, based on an approach where the river basin is the management unit and the active involvement of all affected parties by its river basin management plan is clearly encouraged. The integrated perspective is required to develop sustainable resource management strategies adapted to the i...

This is a summary of the Scientific Peer Review Panel's evaluation of the scientific and technical data, assumptions, and methodologies used by the Southwest Florida Water Management District in the development of its proposed minimum flows and minimum levels (MLFs) for the Upper Peace River. To the best of its abilities, the Peer Review Panel has not only attempted to provide a critical review...

Mathematical models are well known as useful tools for water management practices, directly or indirectly related to the implementation of the Water Framework Directive (WFD) in European countries. They can be applied to solve or understand either simple water quality problems or complex water management problems of trans-boundary rivers or multiple-purpose and stratified reservoirs. Accidental...

Rivers around the world are being regulated by dams to accommodate the needs of a rapidly growing global population. These regulatory efforts usually oppose the natural tendency of rivers to flood, move sediment, and migrate. Although an economic benefit, river regulation has come at unforeseen and unevaluated cumulative ecological costs. Historic and contemporary approaches to remedy environme...

In this paper we propose a new framework to support river management and restoration in more effective way, both conceptually operationally, view of an increasingly challenging future. ‘Development’ almost inevitably leads modifications rivers. These are governed (at best) by planning exercises which typically encompass multiple generally conflicting objectives (whether explicitly or implicitly...

The aim of this paper is to investigate the methods of maintaining desired flow conditions in the reaches of the ecologically valuable upper reaches of the River Narew taking into account the uncertainty in modelling process. The study is based on Global Sensitivity Analysis (GSA) and Generalised Likelihood Uncertainty Estimation (GLUE) techniques applied to a 1-D river flow model. We compare s...

Understanding runoff generation and dynamics is the basis for water resource management, while water isotopic ratios are a potential tool for studying the mechanism on a large scale. In this paper, spatial variations of δ18O and δD of river water and their sources within a large region of the Tarim River were investigated. The results showed obvious spatial variations of both water isotope valu...

In Australia, Ross River virus (RRV) is predominantly identified and managed through passive health surveillance. Here, the proactive use of environmental datasets to improve community-scale public health interventions in southeastern Tasmania is explored. Known environmental drivers (temperature, rainfall, tide) of the RRV vector Aedes camptorhynchus are analysed against cumulative case record...
