Abstract Water pervades all human activities and thus is of fundamental importance for basic human well-being, for economic and social development, and for physical security. Water is also vital for the maintenance of the natural ecosystems on which we all ultimately depend. Thus water managers must be concerned with a large variety of issues, including water-related health issues (safe drinking water, sanitation and water-related diseases), the availability of water for food production, the water needs for energy and industrial production, and the safeguarding of societies from the ravages of floods, droughts and pollution spills. These human needs must always be balanced with consideration for the natural environment. These issues are not independent of each other – they are interlinked and thus must be treated in an integrated manner. The settings in which water managers find themselves are highly varied from region to region and country to country. Not only are climates and hydrologies extremely diverse, but the ways in which societies organize themselves are equally varied. Governance systems are based on the cultures, the religions and the attitudes of peoples. They link to the political settings, to the effectiveness of institutions, to legislative frameworks and to financial instruments. Water managers must find solutions to the challenges facing them, considering the constraints of the systems within which they work. Thus different solutions must be considered for different circumstances. Sciences (hydrological, political, social, economic) provide knowledge and understanding of the systems involved. All are essential in informing water managers in their decision-making. Hydrological science is of vital importance, but is just one of many relevant sciences.

On the complementary roles of the hydrological analyst and the decision-maker in water resources management

AbstractDecisions about water resource management are made in the presence of uncertainty about future events, whether these be reservoir inflows, water demand, or the consequences of climate change. The framework for any decision-making process therefore consists of the following elements: (a) a list of future events that may or may not occur; (b) the probabilities of these events; (c) a list of possible decisions, from which one – the “optimum” – must be selected by the decision-maker; (d) measures of the consequences of each decision according to which uncertain event occurs. These consequences may sometimes be expressed in monetary terms (losses), but more often must be expressed in terms of utility. When the optimal decision is that which maximizes expected utility (minimizes expected loss), the paper discusses the roles of the hydrologist and the decision-maker in assessing the elements (a) to (d) above, showing how these roles complement each other. In particular the role of the hydrologist in determining probabilities (item (b) of the above) is discussed, in the context where probabilities must be evaluated for events which have not occurred in the past. The paper also shows why maximizing expected utility (or minimizing expected loss, when consequences can be expressed in terms of money) is better than minimizing the maximum loss (MINIMAX) criterion for selecting the best decision.

The contribution of the legal aspect of hydrology to the management of international water resources

Abstract Hydrology as a general science, comprises different aspects, one of which is legal. While the technical aspects of hydrology could never be neglected in the management of international freshwater resources, the legal aspect could prove to be of equal importance. Respect for the law that governs the management of international rivers, lakes and aquifers is necessary in order to provide sustainable development and to avoid potential conflicts between riparian states. Therefore, this paper examines the contribution of international law in the management of international water resources; in particular with the legal principles, as they are incorporated in the United Nations (UN) Convention of the Non-Navigational Uses of International Watercourses and their effect in the sound and integrated management of water resources that are shared between two or more states. It argues that the purpose of the drafters of the Convention was to create an international legal framework in order to facilitate the management of water resources.

Abstract Today there are numerous hydrological models available for calculating water balance components at different spatial and temporal scales. So, a selection of one suitable hydrological model, which serves as a module in a more complex decision support system for integrated water resources management, should not be a problem. However, more closely reviewing the specific requirements of hydrological modelling in IWRM reveals that not many models really fulfil all the needs. This contribution presents a hybrid modelling framework for IWRM, discusses requirements of a hydrological model as part of such a system, and then compares the three different hydrological models: HEC-HMS, WASIM-ETH and SWAT regarding their suitability for such a task. The results show that none of the models fulfils all requirements in an optimal sense, and that there is still a lot of work to do on hydrological modelling for integrated water resources management.

Abstract The Hydrological Atlas of Austria (HAA) is presented as an effective and efficient tool to provide spatial hydrological information consistently for the whole country to engineers, water resources managers and the public. The information is cartographically communicated on 52 map sheets, with a total of more than 100 thematic maps. The structure of the atlas shows the different components of the hydrological cycle; it has chapters considering water and mass balances, and covers the themes of water management as well as those of water-related environmental issues. Being a dual-mode product, the printed version is accompanied by a digital, GIS-based version on CD-ROM, including convenient viewing software and the data sets in industry-standard GIS formats. Only one year after publication, a wide range of applications is reported, both by administrative institutions and civil engineers.

Abstract Global and regional climate changes and anthropogenic impacts are the leading factors determining the future state of large river basin water systems which play important roles in the economic development of Russia. That is why it is necessary to create integrated scenarios of river runoff changes within large river basins. Such scenarios should make one of the main bases for ecologically safe management of water systems in the future. Integrated scenarios include the following components: (a) Scenarios of global climate change and methods of their assimilation. (b) Scenarios of hydrological consequences caused by climate changes. (c) Scenarios of hydrological consequences of socio-economic development, including changes in the water management complexes. Results of development of integrated scenarios are submitted by the example of LenaRiver basin – one of the largest rivers of Northern Eurasia. It is especially important for permafrost regions of Russia which covers two thirds of its territory.

Abstract MOBIDIC (MOdello di Bilancio Idrologico DIstribuito e Continuo) is a distributed hydrological modelling package for various applications. The main innovations concern: (a) the coupling of the water balance in the soil and vegetation with the surface energy balance, to the benefit of evapotranspiration computation and the use of remotely-sensed maps for calibration and validation; (b) the interaction between groundwater and surface water bodies, (c) the capability of easily managing data on withdrawals of water, reservoir operation and environmental flow. MOBIDIC-WRM can be used as an effective tool for the evaluation of basin scenarios (e.g. effects of changes in land cover/deforestation and irrigation strategies, exploitation policies for groundwater). It provides a reliable hydrological base for the assessment of crisis indicators such as vegetation stress and lack of environmental flow. In this work we present an application in the Arno basin, central Italy. The outcome of applying the package in order to determine the water budget management strategies is discussed.
