  • 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 ...

  • Snow Hydrology

    Snow hydrology (hydrology, from Greek word Hydrologia, “study of water”)is a scientific study in the field of hydrology which focuses on the composition, dispersion, and movement of snow and ice.Studies ...

  • Urban Hydrology

    The provision and disposal of water for urban populations is as old as the development of cities themselves. Unrestrained development has made the task ever more difficult and hydrologists and civil engineers face constant pressures to stay on top of the challenges of providing sufficient supplies and adequate treatment/disposal of effluents. Urban areas have long existed as centres of trade, ...

  • Queensland: a water sensitive future

    South East Queensland (SEQ) is planning a water sensitive future for the region and its cities. In order to the transition to be successful, it is necessary to develop an implementation plan. This plan aims is to identify a common vision that focuses on the transition pathway and mechanisms the region needs, to become a water ...

  • 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 ...

  • Hydrology vs sovereignty: managing the hydrological interdependency of international rivers

    In managing international rivers, governments are subject to two different boundaries. The socio-politically constructed boundaries governed by sovereignty and the physical boundaries imposed by the river's hydrology. The existence of a hydrological interdependency within an international basin means that “how” it is managed is important in constructing certainty in water supply. We compare two ...

  • Hydrology with impact: how does hydrological science inform decision-makers?

    Water plays a central part in many aspects of life, and good hydrological science is needed to inform many decisions that affect human health and livelihoods. Hydrological scientists are aware of the importance of their work, and make great efforts to develop relevant research and advice. Decision-makers want to use the best science in their decisions, but rarely read academic papers or attend ...

  • 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 ...

  • History and perspectives of hydrological catchment modelling

    This paper presents a brief historical excursus on the development of hydrological catchment models together with a number of possible future perspectives. Given the wide variety of available hydrological models which, according to the embedded level of prior physical information, vary from the simple input–output lumped models to complex physically meaningful ones, the paper suggests how ...

  • Synthesis of incoming shortwave radiation for hydrological simulation

    Over the past decade, measurements of incoming shortwave radiation and of its proxy, daily bright sunshine hours, have become scarce in western Canada and elsewhere. As these data are critical for computing net radiation for snowmelt, evaporation, soil thaw and other components of the hydrological cycle, other means to estimate incoming shortwave radiation are needed. National Centers for ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Monitoring System for Hydrologic Evaluation of Landfill Covers

    Three test sections were constructed and instrumented to assess the hydrologic behavior of earthen final covers at two municipal solid waste landfills. A traditional design using a “resistive barrier” was used for two of the test sections, whereas an alternative design using a “capillary barrier” was used for the third test section. The test sections were built in two distinctly different ...

  • A preprocessing program for a distributed hydrological model: development and application

    A preprocessing program for a distributed hydrological model is very important because it will greatly influence the results of runoff simulation. Runoff simulations include several procedures, such as the determination of flow directions, definition of runoff routing orders, estimation of flow accumulation areas and extraction of drainage networks, etc. In order to simplify the development work ...
