  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...

  • Global study of lakes enhances understanding of hydrological cycle

    We now have much more robust data available on the amount of water in lakes worldwide thanks to a comprehensive database created by researchers at McGill University in Montreal. The McGill scientists discovered the total shoreline of the world’s lakes is more than four times longer than the global ocean coastline. At 7 million kilometers, this is 10 times the distance from the Earth to the ...

  • Reconciling hydrology with engineering

    Hydrology has played an important role in the birth of science. Yet practical hydrological knowledge, related to human needs for water storage, transfer and management, existed before the development of natural philosophy and science. In contemporary times, hydrology has had strong links with engineering as its development has been related to the needs of the design and management of water ...

  • Modelling provenance in hydrologic science: a case study on streamflow forecasting

    The web, and more recently the concept and technology of the Semantic Web, has created a wealth of new ideas and innovative tools for data management, integration and computation in an open framework and at a very large scale. One area of particular interest to the science of hydrology is the capture, representation, inference and presentation of provenance information: information that helps ...

  • Climate change, urbanisation and hydrological impacts

    This paper is a review of recent studies that addressed the hydrological impacts, especially on streamflow, of climate change and/or urbanisation. Articles published between 1996 and 2002 on this subject were reviewed focusing on research methods and results. The main issues addressed with regard to research methods include development of climate change and urbanisation scenarios, assessment of ...

  • Climate change consequences on hydrology: a pilot study from Bhola district, Bangladesh

    Impacts of climate changes on natural hydrology have been primarily documented at macro scale than micro scale. This is not surprising due to the limited data and information available at local level. Hence, this study aimed to explore climate change consequences on coastal hydrology using Bhola City as study area in Bangladesh. Hydro-meteorological data for 1951-2007 were used to develop the ...

  • Hydrological projections based on the coupled hydrological–hydraulic modeling in the complex river network region: a case study in the Taihu basin, China

    Water resources in the Taihu basin, China, are not only facing the effects of a changing climate but also consequences of an intensive urbanization process with the abandonment of rural activities and the resulting changes in land use/land-cover. In the present work, the impact of climate change and urbanization on hydrological processes was assessed using an integrated modeling system, coupling ...

  • Braided rivers: structure, types and hydrological effects

    Braided rivers have been intensively analyzed mostly by geomorphologists. In the present study the approach to recognize braided channel types and effects with the special emphasis on flow partitioning has been applied. It is assumed that each braided channel represents the reach which is initiated with dividing of the single channel and completed below the confluence of the total multiplicity ...

  • Groundwater, flooding and hydrological functioning in the Findhorn floodplain, Scotland

    A large floodplain of the River Findhorn, northeast Scotland, was investigated using hydrogeological and hydrochemical methods (including residence time indicators) to characterise groundwater/surface-water coupling and groundwater flooding. The study demonstrated widespread stratification within the floodplain: shallow (<8 mbgl) deposits are highly permeable (100 m/d); deeper deposits ...

  • Statistical evaluation of bioretention system for hydrologic performance

    Long-term retention performance is a common performance indicator for low-impact development practices, such as rain barrels, rain gardens, and green roofs. This paper introduces a numerical approach for the estimation of annual retention ratios of stormwater by bioretention. The annual retention ratio is taken as the ratio of the annual accumulated volume of stormwater retained by bioretention ...

  • Green roof hydrologic performance and modeling: a review

    Green roofs reduce runoff from impervious surfaces in urban development. This paper reviews the technical literature on green roof hydrology. Laboratory experiments and field measurements have shown that green roofs can reduce stormwater runoff volume by 30 to 86%, reduce peak flow rate by 22 to 93% and delay the peak flow by 0 to 30 min and thereby decrease pollution, flooding and ...

  • Patterns of evolution of research strands in the hydrologic sciences

    This paper examines issues of impact and innovation in groundwater research by using bibliometric data and citation analysis.The analysis is based on 3120 papers from the journal Water Resources Research with full contents and their citation data from the ISI Web of Science. The research is designed to develop a better understanding of the way citation numbers can be interpreted by scientists. ...

  • Data mining process for modeling hydrological time series

    The main purpose of this study was to develop an optimum flow prediction model, based on data mining process. The data mining process was applied to predict river flow of Seyhan Stream in the southern part of Turkey. Hydrological time series modeling was applied using monthly historical flow records to predict Seyhan Stream flows. Seyhan Stream flows were modeled by Markov models and it was seen ...

  • Sensitivity-guided evaluation of the HBV hydrological model parameterization

    Applying hydrological models for river basin management depends on the availability of the relevant data information to constrain the model residuals. The estimation of reliable parameter values for parameterized models is not guaranteed. Identification of influential model parameters controlling the model response variations either by main or interaction effects is therefore critical for ...

  • 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 ...

  • Sensitivity analysis of hydrological models: review and way forward

    Different hydrological models provide diverse perspectives of the system being modeled, and inevitably, are imperfect representations of reality. Irrespective of the choice of models, the major source of error in any hydrological modeling is the uncertainty in the determination of model parameters, owing to the mismatch between model complexity and available data. Sensitivity analysis (SA) ...

  • A hydrological assessment of the November 2009 floods in Cumbria, UK

    In November 2009, record-breaking rainfall resulted in severe, damaging flooding in Cumbria, in the north-west of England. This paper presents an analysis of the river flows and lake levels experienced during the event. Comparison with previous maxima shows the exceptional nature of this event, with new maximum flows being established at 17 river flow gauging stations, particularly on catchments ...

  • Modelling the hydrologic effects of land-use and climate changes

    Climate and land use affect water quantity and quality; however, the complex relations of climate and land use regarding flow and instream nutrient levels have yet to be elucidated. This study aims to assess the hydrologic effects of different land-use and climatic regimes in the Lower Great Miami River Basin. The modelling results from BASINS showed that, as expected, agricultural lands and the ...
