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

Highly concentrated precipitation during the rainy season poses challenges to the South Korean water resources management in efficiently storing and redistributing water resources. Under the new climate regime, water resources management is likely to become more challenging with regards to water-related disaster risk and deterioration of water quality. To alleviate such issues by adjusting management plans, this study examined the impact of climate change on the streamflow in the Bocheongcheon basin of the Geumgang river. A globally accepted hydrologic model, the HEC-HMS model, was chosen for the simulation. By the calibration and the validation processes, the model performance was evaluated to range between “satisfactory” and “very good”. The calibrated model was then used to simulate the future streamflow over six decades from 2041 to 2100 under RCP4.5 and RCP8.5. The results indicated significant increase in the future streamflow of the study site in all months and seasons over the simulation period. Intensification of seasonal differences and fluctuations was projected under RCP 8.5, implying a challenge for water resources managers to secure stable sources of clean water and to prevent water-related disasters. The analysis of the simulation results was applied to suggest possible local adaptive water resources management policy.

As a result of the research, the priority tasks of water policy regarding the formation of integrated water resources management system are grounded taking into account the eurointegration vector of Ukraineʼs development. The necessity of the development of water management forecasts and scenarios for the purpose of creating an information base for choosing the optimal variant for the formation of the concept of concrete actions of water resources management of the river basin has been proved. The theoretical and methodological approaches to the development of river basin management plans in the implementation of the basic provisions of the European Union water directives in the national legislation are proposed. The main mechanisms for implementation of river basin management plans are defined and classified.

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

Abstract. Daily evapotranspiration is a major component in water resources management plans. In arid ecosystems, the quest for efficient water budget is always hard to achieve due to insufficient irrigational water and high evapotranspiration rates. Therefore, monitoring of daily evapotranspiration is a keystone practice for sustainable water resources management, especially in arid environments. Remote Sensing Techniques offered a great help to estimate the daily evapotranspiration on a regional scale. Existing open source algorithms proved to estimate daily evapotranspiration in arid environments comprehensively. The only deficiency of these algorithms is course scale of the used remote sensing data. Consequently, the adequate downscaling algorithm is a compulsory step to rationalize an effective water resources management plans. Daily evapotranspiration was fairly estimated using AATSR in conjunction with MERIS data acquired in July 2013 with one-kilometer spatial resolution and 3 days temporal resolution under SEBS model. Results were validated against reference evapotranspiration ground truth values using standardized Penman-Monteith method with R2 of 0.879. The findings of the current research are successfully fulfilled to monitor turbulent heat fluxes values estimated from AATSR and MERIS data with a temporal resolution of 3 days only in conjunction with reliable meteorological data. Research verdicts are necessary inputs for well-informed decision-making process regarding sustainable water resources management

Degradation of watersheds and diminishing water resources lead to unsustainable environmental and socio- economic development. The hydrological characteristics are desirable for sustainable water resource exploitation. Hydrological and water resources research were examined in three case watersheds in Kenya leading to the need for integrated water resources management, environmental conservation, and watershed management plans as a result of the major challenges of climate change and variability and uncoordinated watershed resource utilization. Well-managed hydro-meteorological networks at different scales of hydrological systems have been proposed to assess potential for optimal resource use and harmony involving all stakeholders for reduced water stress and future water conflicts. Updates of information and methodologies for watershed management that emphasize collaborative efforts and use of sustainable best practices would require input of various stakeholders including Water Resources Management Authority (WRMA), Basin Authorities, and National Environmental Management Authority (NEMA).
