Decision Support for the Selection of Measures according to the Requirements of the EU Water Framework Directive 总被引:1,自引:1,他引:0
Bernd Klauer Michael Rode Johannes Schiller Uwe Franko Melanie Mewes 《Water Resources Management》2012,26(3):775-798
One major scientific challenge posed by the EU Water Framework Directive (WFD) is the design of a decision support process
that meets the Directive’s requirement to achieve “good status” for all water bodies using a cost-effective combination of
measures. This paper presents BASINFORM, a new decision methodology for selecting cost-effective management measures, developed in close co-operation with the
water authorities and tested in the 5,154 km2 mesoscale river Weisse Elster in central Germany. BASINFORM comprises (i) a procedure for framing the specific problems in the water bodies, including quantification of the need
for action, (ii) modelling tools for quantifying the impacts of management measures, and (iii) a method for selecting cost-effective
combinations of measures. One innovative feature of BASINFORM is that it structures the complex decision problems appropriately for practical use and provides an easy-to-use framework
for integrating scientific and practical knowledge. A trial run applying BASINFORM to the Weisse Elster catchment revealed that good surface water status with respect to nutrient levels cannot be achieved
if only the “standard” actions of current water management are taken to reduce point sources (sewage treatment) and diffuse
agricultural sources. It also became clear that the nutrient-reduction measures available will generate considerable costs.
The application of BASINFORM in this case study demonstrated its practical applicability in the WFD implementation process. Beyond the case study
described here BASINFORM is currently being used for practical implementation of the WFD in the German Federal State of Thuringia. 相似文献

Adaptation to Climate Change in the Management of a Canadian Water-Resources System Exploited for Hydropower 总被引:3,自引:2,他引:1
Marie Minville François Brissette Stéphane Krau Robert Leconte 《Water Resources Management》2009,23(14):2965-2986
The management adaptation potential of the Peribonka River water resource system (Quebec, Canada) is investigated in the context
of the evolution of climate change. The objective of this study is to evaluate the impacts on hydropower, power plant efficiency,
unproductive spills and reservoir reliability due to changes in the hydrological regimes. The climate change projections used
here are from the Canadian regional climate model (CRCM) nested by the Canadian-coupled global climate model (CGCM3) forced
with the SRES A2 greenhouse gas emission scenario. The hydrological regimes were simulated with the distributed hydrological
model Hydrotel. They were incorporated into a dynamic and stochastic optimization model in order to adapt the operating rules
of the water resource system annually, according to the evolution of the climate. The impacts were analyzed over the years
1961–2099, split into four periods for comparison purposes: control period (1961–1990), horizon 2020 (2010–2039), horizon
2050 (2040–2069) and horizon 2080 (2070–2099). The main results indicate that annual mean hydropower would decrease by 1.8%
for the period 2010–2039 and then increase by 9.3% and 18.3% during the periods 2040–2069 and 2070–2099, respectively. The
trend to increase is statistically significant starting from 2061 (Mann–Kendall with p = 5%). The change in the mean annual production is statistically significant for the 2040–2069 and 2070–2099 periods (t-test with p = 5%). Also, the change in the variance is significant for the periods 2010–2039, 2040–2069 and 2070–2099 (F-test). Annual mean unproductive spills would increase from 1961–2099, but the trend is not statistically significant. However,
the changes in the variance of the annual mean spills are significant in the periods 2010–2039, 2040–2069 and 2070–2099. Overall,
the reliability of a reservoir would decrease and the vulnerability increase as the climate changes. 相似文献

power system is described. Two vital questions have arisen in the course of this work: ensuring the functionality and reliable
operation of equipment which has outlived its design lifetime and refitting the power stations to enhance their performance,
reduce their environmental impact, and improve their operational characteristics in accord with the demands of the 21st century.
