The Creation

The decrease of available water resources, the water quality degradation as well as the rapid increase of population combined with the growth of human activities, impose today the development of a science that concerns the Management of Water Resources. Lake Volvi faces a lot of problems, the most important being the water level drop, which is mostly due to the big quantities of water flowing through to Rihios River and to the wrong management of irrigation water. The study area of the present research consists of the watershed of Lake Volvi, situated in Northern Greece, 39 km away from the city of Thessaloniki. The objective of this study is the estimation of the water balance of the hydrologic basin of Lake Volvi with a Corporate Management program, using Visual Fortran and the creation of scenarios for better management of the water resources of the region. Lake Volvi is situated next to Lake Koronia, both of them belonging to a wider region that forms the geological basin of Mygdonia. Lake Volvi is the recipient of the water draining from Lake Koronia. The water that drains from Lake Volvi is discharged into the gulf of Strymonikos through Rihios River. Firstly, a close analysis is attempted for the estimation of the water balance of the entire hydrologic basin of Lake Volvi with the method of Turc, which is used widely throughout the world. Next, in order to simulate the lake, an administrative model is used, written in Visual Fortran. A rational management of the hydrological elements of the region is attempted with the creation of four alternative scenarios. After the execution of the Corporate Management program, the results show that the main problem for Lake Volvi is the water leaking to Rihios River. Moreover, the research also shows that it is important to reduce the water used for irrigation. As a final result, it is an imperative need to develop water resources management plans for the restoration of the entire region.

The Impact

A study on the impact of silvicultural practices on the water balance was carried out in a watershed in Calabria, southern Italy, the prevalent cover of which is Calabrian pine stands. A thinning was carried out in 1993, which removed 50% of the total number of trees (about 30% of the basal area), and the catchment hydrological response before and after the intervention was compared. After thinning, differences were observed in yearly runoff, with a significant increase in groundwater flow during spring and summer. In light of this evidence, we assume that silvicultural interventions can contribute significantly to improve water resources management, particularly in regions with a long dry season, as in the Mediterranean area. Key words: Pinus laricio, runoff, small catchment, thinning, water resources management

In the 1990s water quality protection was underdeveloped in Central and Eastern Europe (CEE) compared to EU 15 countries in most indicators. After the CEE countries joined the EU, all of them started to invest significant amounts to implement the requirements of EU water policies in the field of waste water collection and treatment, where efficient use of resources was function of several factors. In Hungary, a new National Sewerage and Waste Water Treatment Strategy was elaborated, which predicted that during the subsequent decade, the amount of sludge produced at waste water treatment plants would increase significantly. Environmental impacts and economical deposition of the increased amount of sludge have not been investigated in the Strategy. The paper presents an investigation, which was carried out with the application of a newly developed GIS based decision support methodology to identify suitable agricultural areas for deposition of the predicted increased amount of sludge taking into consideration multi-criteria hydrological, environmental, technical, economic and societal conditions that are all important in regional water resources management. The investigation included the entire territory of Hungary. It was concluded that only 25% of the agglomerations indentified in the Strategy has actually enough agricultural land for sludge utilization or other word: placement. This fact influences the investment and upgrading programmes of the waste water treatment plants in the future.
