Updating of Feed Pumps for 150 – 1200-MW Power Units at the Kaluga Turbine Plant

Suggestions concerning updating of main feed pumps of Russian thermal power plants are considered. Causes of pump failure are analyzed and recommendations are given for improving their operating characteristics. The updating of PN 1500-350-1 pumps at the Kaluga Turbine Plant (replacement of eight-channel guide vanes by twelve-channel whole-milled ones, use of 'cellular' seals, additional hydrostatic bearing unit in the middle stage of the rotor, and process measures) has substantially improved the vibration characteristics and increased the reliability. The pump of the 800-MW generating unit of the Perm Regional Hydro Power Plant has run for 5000 h. Recommendations are given for further improvement of the characteristics and the reliability. It is shown that the condensate-feed system can be simplified and made more reliable by realizing a circuit without booster and using preliminary startup of an axial-vortex stage in the feed pump. The updating performed by the KTP is flexible and adaptable to financial possibilities of customers.

Some Foci of Integrated Water Resources Management in the“South” which are oft- forgotten by the “North”: A perspective from southern Africa

Following some definitions of IWRM within a context of integrated catchment management, and a summary of the major goals and strategies as well as scale considerations in IWRM, this paper highlights some differences between IWRM in Lesser Developed Countries (LDCs), i.e. the so-called “South”, and Developed Countries (DCs), i.e. the so-called “North”, by outlining characteristics of DCs and LDCs which shape their respective needs in IWRM. Thereafter inherent problems in regard to IWRM in LDCs are identified. This is followed by examples from four case studies in southern African catchments which focus on some of the uniquenesses of IWRM issues in LDCs which, in the author's experiences, are often forgotten by theorists and practitioners from the “North”,viz.that

Implementing the European “Floods Directive”: the Case of the Po River Basin

The European “Floods Directive” 2007/60/EC (FD) asks Member States to develop flood risk maps on the bases of most appropriate and advanced tools, with particular attention on limiting required economic efforts. The question arises on how these tools should be selected so as to supply all the knowledge that is required to develop Flood Risk Management Plans (FRMPs). By analysing the implementation of the FD in the Po River Basin (Italy), the paper describes and compares two different approaches for flood risk assessment: the expert driven-qualitative approach vs. the quantitative approach based on damage models. The comparison shows, as expected, that quantitative approaches supply more useful knowledge for the development of FRMPs (and for flood risk management in general) with respect to qualitative approaches. However, they still present limits which prevent their adoption without critically consider the peculiarities of the investigated area in terms of available knowledge on hazard, exposure and vulnerability. Accordingly, considerations are supplied on how effectiveness of quantitative approaches can be maximized, towards flood risk management objectives.     

Late developers and the inequity of “equitable utilization” and the harm of “do no harm”

This paper critically examines the Helsinki Rules (1966 Helsinki Rules, 1966. http://www.colsan.edu.mx/investigacion/aguaysociedad/proyectofrontera/Helsinki%20Rules%201966.pdf (http://www.colsan.edu.mx/investigacion/aguaysociedad/proyectofrontera/Helsinki%20Rules%201966.pdf) (Accessed: April 2010).  [Google Scholar]), the United Nations Convention (1997) and the Berlin Rules (2004 Berlin Rules, 2004. http://www.cawater-info.net/library/eng/l/berlin_rules.pdf (http://www.cawater-info.net/library/eng/l/berlin_rules.pdf) (Accessed: April 2010).  [Google Scholar]), looking at their emphasis on the principle either of equitable utilization or of doing no harm and analysing the effect of these principles on late developers within a river basin. The analysis reveals that these rules increasingly favour first developers. Today, late developers have even less incentive to subscribe to these rules, but instead must either utilize their own dominance or have a powerful ally to develop their water resources. Given the Millennium Development Goals, the existing recommendations on the sharing of international rivers should be revised so as not to favour the early developers.

Thinking outside the “water box” in the Detroit River Area of Concern

Despite sustained attention to water resource issues in the Great Lakes and around the world, many water problems remain unresolved because their sources or causes are external to the water sector. Water governance often is based on water-centric problem framings that do not take sufficient account of the role of external actors, institutions, and drivers. Recognition of this problem is growing, but identifying external connections and addressing the critical ones is challenging for water managers. Using a flexible diagnostic process, we explore external factors that are relevant in the context of the Detroit River Area of Concern (AOC) between Canada and the United States. We used a two-case multiple case study research design, triangulating data gathered from 28 key informant interviews, review of 58 documents, and personal observations. We find that the AOC program is intentionally narrowly-focused to achieve its objectives, and that a water-centric perspective may in fact be needed for delisting the Detroit River as an AOC. However, there are broader issues beyond those considered in the AOC process that affect the river, including climate change, invasive species, population and land use change, shifting public perceptions, and an unstable institutional environment. To address these external challenges, practitioners should consider engaging more proactively with the topic of “life after delisting”, and connecting more strongly with existing initiatives and networks in the area with the help of “boundary spanners.” Strengthening binational ties within the AOC, and clarifying the role of AOCs in the large governance environment are also important.     

Discussion of the paper entitled “Ethiopian Interests in the Division of the Nile River Waters”[l]

ABSTRACT

It is argued that the establishment of tradable water rights will play an important role in increasing productivity and sustainability of water use in developing countries. Due to economic growth, scarcity is expected to be conducive to water market development. This article presents the potential for and feasibility of markets in water rights in Jordan through a comparative study of Chile, Mexico, and California. Many lessons were learned from the experiences of those countries concerning water markets. The transformation of these lessons to the Jordanian context is faced with some fundamental challenges in terms of water legislation, institutional structure, and data. Water legislation must deal with externalities, dispute, and third-party effect. Adopting a new water act and review of water laws is essential for better water resources management and assured public input and feedback. Market oriented policy should be introduced only on a pilot basis in terms of pricing. Policy makers believe that dealing with future water scarcity in Jordan will be achieved through better management and utilization of water using both conventional and nonconventional sources. Moreover; policy makers and farmers in Jordan expressed strong reservations on intersectoral water transfers because of the importance of water to the Jordanian economy.
