  • 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, ...

  • 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 ...

  • 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 ...

  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A generic hydrological model for a green roof drainage layer

    A rainfall simulator of length 5 m and width 1 m was used to supply constant intensity and largely spatially uniform water inflow events to 100 different configurations of commercially available green roof drainage layer and protection mat. The runoff from each inflow event was collected and sampled at one-second intervals. Time-series runoff responses were subsequently produced for each of the ...

  • Long-term changes in hydrological regime of the lakes in Latvia

    Changes in the hydrological regime of the lakes of Latvia depend on natural and anthropogenic causes. This publication summarises the results of the research on the long-term changes in the water level, thermal and ice regimes in the seven largest lakes of Latvia: Liepājas, Usma, Ķīšezers, Burtnieks, Rāzna, Sventes and Lielais Ludzas, and their regional ...

  • Hydrological response of the Ötztal glacierized catchments to climate change

    This paper investigates the hydrological response of glacierized headwater catchments to future climate change in the Ötztal Alps, Austria. To this end, two conceptual hydrological models, HBV (Hydrologiska Byråns Vattenbalansavdelning) and HQsim, are applied for the simulation of future daily discharge in three (nested) catchments with varying degrees of glaciation. The models are forced ...

  • 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 ...

  • Data quality assessment in hydrological information systems

    The hydrological data fed to hydrological decision support systems might be untimely, incomplete, inconsistent or illogical due to network congestion, low performance of servers, instrument failures, human errors, etc. It is imperative to assess, monitor and even control the quality of hydrological data residing in or acquired from each link of a hydrological data supply chain. However, the ...

  • Integrated actions in the management of critical hydrologic events

    Owing to the increase in urban populations, there has also been an increased incidence of critical events, especially those related to floods and landslides. Since the implementation of the National Civil Defense System in Brazil, a focus on disaster management is no longer the answer when assisting those affected; instead, the answer has become managing disaster risk, in addition to the ...

  • The eReefs data brokering layer for hydrological and environmental data

    The environmental sciences are witnessing a data revolution as large amounts of data are being made available at an increasing rate. Many datasets are being published through operational monitoring programs, research activities and global earth observation virtual laboratories. An important aspect is the ability to query relevant metadata which can potentially provide useful information to ...

  • Simulating the hydrologic response of a semiarid watershed to switchgrass cultivation

    The conversion of land from existing uses to biofuel cultivation is expected to increase given concerns about the sustainability of fossil fuel supplies. Nonetheless, research into the environmental impacts of biofuel crops, primarily the hydrological impacts of their cultivation, is in its infancy. To investigate such issues, the response of a 1,649 km2 semiarid basin to the incremental ...

  • Intelligent manipulation and calibration of parameters for hydrological models

    It would be greatly helpful to neophytes if knowledge-based system technology incorporating the existing heuristic knowledge about model manipulation can be integrated into the hydrological system. This paper delineates the development and implementation of a prototype knowledge-based system for model manipulation for hydrological processes by employing an expert system shell. The architecture ...
