مستخلص: Water is a vital substance, essential for most life processes and as a liquid flow resource is the connector of all components of ecological and life systems. It is the environmental integrator. As a resource, water is both a natural component of nature and a commodity, or resource, that may be used by people for the benefit of society. This use is called management. Water has inherent characteristics that allow it to maintain processes and thus provide services;this inherent character is called the carrying capacity. Examples of carrying capacity may be waters ability to assimilate wastes, or dissipate excessive heat, or support a given amount of life. If the effects of such activities become large in magnitude and exceed the carrying capacity of water, it becomes srtessed and its capabilities to provide the services may cease.If ecosystems become stressed and impaired those that are dependent on ecosystems likewise become stressed, including human beings. As the liquid that connects all components of ecosystem there are symptoms, called environmental indicators, that may be used to assess the stress level of water; much like there are indicators that are employed to assess stress levels in human systems, e,g, pH, content of chemicals,presence of microbes. Indicators must represent or be correlated with effects of management. In addition these indicators must be relevant, acceptable, measurable, timely and sensitve. To asses effects of management and potential irreversible impact on water systems some reference for comparison is most helpful. One approach in flow water systems is the "input-output" model. Here an indicator is chosen and measured prior to an activity and measured again following the activity; this provides an index of impact and degree of stress. Keywords: environment; indicators; carrying capacity; water resources management [ABSTRACT FROM AUTHOR]

مستخلص: Conflicts between nature protection and natural water resources exploitation arise only when intensive use of water recourses provokes stress in water ecosystems. In water management it is very important to define the ecological and human carrying capacity of water ecosystems. Determination of indicators helps to do this. That was one of the goals of the "Integrated Water Management" pilot study. Since 1984 the biggest Lithuanian Druksiai Lake has started to serve as a cooler for the Ignalina Nuclear Power Plant (INPP). The INPP operation has disturbed the natural hydrological and hydrothermal regime causing intensified evaporation and exerting impact on the lake hydrochemical properties. The above mentioned effects have led to irreversible changes in the unique lake ecosystem. The aim of this case study is to evaluate the changes in the lake ecosystem due to the impact of the nuclear power station. Water temperature is determined as an indicator of the effects in the lake ecosystem. Keywords: water temperature; cooler-lake; nuclear power plant [ABSTRACT FROM AUTHOR]

مستخلص: Bulgaria has suffered from considerable economic damages in the past and today, because of frequent droughts and floods. Throughout 1982-1994 one of the drought periods was observed. The runoff diminished and this led to dangerous decline of water levels in reservoirs, and was a major reason for a limited supply of drinking water. Particularly dangerous for drinking water quality were the cases of reaching the water minimum in the reservoirs. This phenomenon was also due to some faults in water management related to water allocation. In many drinking water treatment plants appropriate anti-turbidity and oxidation reagents, reagents for manganese, iron and phytoplankton removal were not used, because of inadequate water treatment technologies applied. A case study for establishing the Iskar Reservoir Minimum Sanitary Storage Capacity (MSSC) according to the water treatment technologies was carried out. The specific chemical and biological water quality state indicators coherent to the water supply function were specified and investigated during one-year period, and the obtained results are given and discussed. In conclusion recommendations that could improve drinking water supply management are made and an attempt for environmental indicators classification for the Iskar Reservoir is made, which could assist policy- and decision-makers in taking useful advanced actions. Keywords: Iskar Reservoir, water quality, sanitary storage capacity, environmental indicators [ABSTRACT FROM AUTHOR]

مستخلص: The Ulster Blackwater River has a cross-border catchment and is one of the major inflowing rivers of Lough Neagh. It is a traditional salmon fishery that has been impacted by channelisation and eutrophication. There is evidence linking agricultural soils as sources of acute mass phosphorus transfer to the river system during storm events and chronic phosphorus transfers from other sources compound this during non-storm periods. Management of this particular impact is being demonstrated in a project in three 5km2 sub-catchments of the Blackwater River. The aims are to define and mitigate against both acute and chronic phosphorus transfers and to focus this management within a landscape framework. This work integrates agricultural stakeholders with scientists and a tripartite organization of local jurisdictions. Keywords: eutrophication; phosphorus; catchments [ABSTRACT FROM AUTHOR]

مستخلص: In this paper we discuss new practices in water management regarding the involvement of people and stakeholders in the policy-making process. We intend to identify criteria that help in selecting a suitable type of participation for a specific case. After a broad exploration of some basics in literature about decision-making and public participation, we concentrate on adaptive management resulting from the ecosystem approach. Based on the level of interaction, we indicate six levels of participation between water managers and actors in society. Keeping in mind a distinction between a pluralist and a corporatist approach, we proceed with major criteria that play a role in the selection of a suitable design for a participatory decision-making. We conclude with some important questions that should be addressed in order to find a model that enables water managers to decide about their optimal styles of public and stakeholder participation in practical cases of decision-making. Keywords: stakeholder participation, interactive policy-making, integrated water management [ABSTRACT FROM AUTHOR]

مستخلص: The Sete Cidades lake in the Azores, is located in a volcanic crater. Increased frequency of logging (380 hectares of production forests) and the use of fertilizers on pastures and forages (450 hectares) that sustain 750 cows, provide direct employment to 67 farmers and induce employment to more 50 actives, but also increases the eutrophycation and sedimentation of the lake. To address the issue an integrated model generates efficient land use scenarios for different degrees of phosphorus emissions with related effects in the water quality. The model is used to obtain various indicators for each scenario that feed a multi-objective program able to find the dominant solutions. The final solution is chosen by the politicians: 600 cows that produce 3.0 millions of milk, provide direct employment to 55 farmers and induce employment to more 41 actives. This, jointly with a partial stream deviation, allows a reduction of 63% of the phosphorus load to the lake. Compensatory measures pay the farmers their losses and compensate the community for the lost employment. Keywords: integrated water management; decision support system; Azores [ABSTRACT FROM AUTHOR]

مستخلص: The coastal freatic aquifer of the Cervia city is polluted by salt water. Protection of fresh groundwater resources in this area is complicated by the presence of multiple stakeholders and by the fragmentation of the authorities responsible for land planning. Most of the topography is under sea level or in its close proximity. Consequently, most of the aquifer does not have a hydraulic head able to prevent the intrusion of the salt wedge at its base (Ghyben-Herzberg principle).Water table and salinity maps show an aquifer almost completely invaded by salt water with bubbles of surface fresh water almost completely confined to elevated areas located near the coast. The study identified as causes of salt water intrusion: direct contamination from canals open to sea, subsidence, drainage of farmland, groundwater extraction from wells along the shoreline (bathing establishments) and, last, groundwater winning from private wells inland. On the basis of these results some mitigation action can be proposed: the lining of the salt canals, a different management plan for the floodgates on the canals, to provide shoreline establishments with freshwater from other fresh water resources as a measure to stop direct tapping from the aquifer. Keywords: Saltwater Intrusion, Unconfined Costal Aquifer [ABSTRACT FROM AUTHOR]

مستخلص: There is a growing pressure on use of the water resources but at the same time, there are growing concerns on the ecological status of surface or ground water dependent ecosystems. Riparian wetlands belong to this group. The ecological characteristics, which describe the status of riparian wetlands, are mostly connected to the phenomena of flooding. In this paper main flood characteristics i.e. flooding area, average depth of flooding and flooding frequency were used in order to evaluate the best release policy of water reservoir located upstream from the protected wetlands. The hydrodynamic model coupled with hydrological models of tributaries and water balance model of water reservoir was used for this purpose. It was found that only average flood can be impacted by the reservoir policy. Extreme events can not be controlled and very small floods can be increased by the reservoir operation in combination with water release from the drainage schemes located on major tributaries. Keywords: water management, hydrodynamic modeling, flood, GIS dynamic analysis [ABSTRACT FROM AUTHOR]
