  • Integrating water resources management in eco-hydrological modelling

    In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of ...

  • Aswan High Dam Reservoir management system

    The Aswan High Dam Reservoir management system was developed to simulate dam operation under varying boundary conditions taking as example climate change and Millennium Dam construction, and analyze the optimal operation rules of the reservoir taking into account a large number of objectives, including hydropower production and water supply for irrigation purposes. The developed system runs on ...

  • Managing Mali’s Wetland Wealth for People and Nature

    Introduction Wetlands International has been in Mali since 1998, when it started a partnership with the national government to help better manage the country’s water resources for both its people and nature. Those early efforts involved scoping out the state of Mali’s unique natural habitats, not least its globally important wetland, the Inner Niger Delta, and sharing those ...

  • Managing Great Lakes Water Levels Adaptively in Response to Changing Climate Conditions

    The Laurentian Great Lakes contain an abundance of fresh water, collectively representing approximately 20% of the fresh surface water available globally. Despite the enormity of this resource, water levels and flows in the Great Lakes are subject to fluctuations caused by changing climate conditions that have cascading impacts on the coastal ecosystem and the regional economy. Proactive ...

  • The Sri Lanka environmental flow calculator: a science-based tool to support sustainable national water management

    As Sri Lankan water resources are being increasingly exploited, particularly for hydropower and irrigation, ecologists, water practitioners and policymakers alike are realizing the importance of protecting these resources and setting environmental sustainability thresholds. Environmental flows (EF) – the concept that helps define such thresholds – has now become an integral part of ...

  • A Bayesian approach to probabilistic streamflow forecasts

    One-month-ahead streamflow forecasting is important for water utilities to manage water resources such as irrigation water usage and hydropower generation. While deterministic streamflow forecasts have been utilized extensively in research and practice, ensemble streamflow forecasts and probabilistic information are gaining more attention. This study aims to examine a multivariate linear ...

  • Stochastic simulation of daily streamflow sequences using a hidden Markov model

    Estimation of daily streamflow time series is of paramount importance for the design and implementation of river engineering and management projects (e.g., restoration, sediment-transport modelling, hydropower). Traditionally, indirect approaches combining stochastic simulation of rainfall with hydrological rainfall–runoff models are used. However, these are limited by uncertainties in model ...

  • Renewable energy and energy efficiency in Bulgaria

    The interest in renewable energy sources (RESs) utilisation and energy efficiency improvement programmes in Bulgaria reflects the changes in the field of energy policy worldwide and in Europe. Now energy management becomes a great problem of inner policy of Bulgarian government. In the last few years there has been a growing attention to the RESs applications. Bulgaria has one of Southern ...

  • Discharge Measurements In Low Flow Conditions With ADC p t echnology – First Experiences In Nepal

    Low flows prevail during about nine months of the year in Himalayan rivers as a result of the influence of the monsoon climate. They account for a large portion of the annual water balance and accurate information about these flows is therefore critical for water resources planning, development, management and hydropower design. Issues that occur with the neighbouring country India are often ...

  • Risks of carbamate and organophosphate pesticide mixtures to salmon in the Pacific Northwest

    Salmon populations in the Pacific Northwest are being affected by a variety of environmental stressors including intense fishing pressure, parasites and disease, climatic variability and change, land development, hatchery production, hydropower operations, stormwater runoff, and exposure to toxic contaminants. In recent years, there has been much concern that mixtures of pesticides are causing ...

  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...

  • Offshore Wind Development Picking Up Pace

    Wind power is the world’s leading source of renewable electricity, excluding hydropower, with 238,000 megawatts of capacity installed at the start of 2012. Thus far, almost all of this wind power has been tapped on land; worldwide just 4,600 megawatts of offshore wind farms were operating as of mid-2012. Offshore wind capacity is growing quickly, however, expanding nearly six-fold ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
