  • Custom functionality and integrative approaches for hydrological modelling tools for water resources planning and management

    This paper outlines the application and usefulness of a software platform that enables hydrologists to develop custom functionality in a new hydrological modelling tool, eWater Source, designed for water resources planning and management. The flexible architecture of the software allows incorporation of third-party components as plug-ins to add new capabilities that are not built in. Plug-ins ...

  • Perils and pleasures of multidisciplinary research

    Over the past two decades various prestigious scientific and engineering organizations have touted the need for multidisciplinary research. Deans and department chairs often see multidisciplinary research as a potential pot of gold, and encourage faculty to follow the rainbow. Senior professors join in, seeking Enlightenment in their waning years, and young professors jump on board ...

  • 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 ...

  • Towards better utilization of NEXRAD data in hydrology: an overview of Hydro-NEXRAD

    With a very modest investment in computer hardware and the open-source local data manager (LDM) software from University Corporation for Atmospheric Research (UCAR) Unidata Program Center, a researcher can receive a variety of NEXRAD Level III rainfall products and the unprocessed Level II data in real-time from most NEXRAD radars in the USA. Alternatively, one can receive such data from the ...

  • The public policies for reducing nonpoint water pollution between equity and efficiency

    This paper investigates if and how equity and efficiency could be reconciled when improving nitrogen-polluted groundwater of agricultural origin. This is achieved through comparing two pollution control programmes with respect to their costs, water quality impacts and correlation between abatement cost and polluting emissions. The fieldwork was done in a watershed, near the French Alps. It was ...

  • Comparing influence of combinations of precipitation loss and rainfall excess-runoff transform models to flood flow rate in a flatland watershed

    Hydrologists can use many different precipitation loss rate functions and rainfall-excess transform techniques to develop watershed runoff hydrographs. For the most part, they can apply the loss and transform approaches in nearly any combination. To evaluate some of the many possible groupings, we formed a matrix of three commonly used precipitation loss rate models and three rainfall-excess ...

  • Application of deterministic distributed hydrological model for large catchment: a case study at Vu Gia Thu Bon catchment, Vietnam

    In order to create a tool to help hydrologists and authorities to have good understanding about occurrences in stream flow regime together with its variation in the future under the impact of climate change in the Vu Gia Thu Bon catchment, a deterministic distributed hydrological model has been developed and constructed. This model covers the major processes in the hydrologic cycle including ...

  • Statistical characteristics of rainfall in the Onkaparinga catchment in South Australia

    The main objective of this study was to investigate the statistical characteristics of point rainfall and the novelty of the work was the development of a hybrid probability distribution that can model the full spectrum of daily rainfall in the Onkaparinga catchment in South Australia. Daily rainfall data from 1960 to 2010 at 13 rainfall stations were considered. Spatial dependency among the ...

  • Examining differences in streamflow estimation for gauged and ungauged catchments using evolutionary data assimilation

    Data assimilation has allowed hydrologists to account for imperfections in observations and uncertainties in model estimates. Typically, updated members are determined as a compromised merger between observations and model predictions. The merging procedure is conducted in decision space before model parameters are updated to reflect the assimilation. However, given the dynamics between states ...

  • Hybrid wavelet-support vector machine approach for modelling rainfall–runoff process

    Because of the importance of water resources management, the need for accurate modeling of the rainfall–runoff process has rapidly grown in the past decades. Recently, the support vector machine (SVM) approach has been used by hydrologists for rainfall–runoff modeling and the other fields of hydrology. Similar to the other artificial intelligence models, such as artificial neural network (ANN) ...

  • Modelling the hydrological impacts of rural land use change

    The potential role of rural land use in mitigating flood risk and protecting water supplies continues to be of great interest to regulators and planners. The ability of hydrologists to quantify the impact of rural land use change on the water cycle is however limited and we are not able to provide consistently reliable evidence to support planning and policy decisions. This shortcoming stems ...

  • 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, ...

  • Agricultural biomass monitoring on watersheds based on remotely sensed data

    There is a close quality relationship between the harmful levels of all three drought indicator groups (meteorological, hydrological and agricultural). However, the numerical scale of the relationships between them is unclear and the conversion of indicators is unsolved. Different areas or an area with different forms of drought cannot be compared. For example, from the evaluation of ...

  • City of Billings Case Study: Complex floodplain issues

    Introduction: In 1937, a major flood of Yellowstone River tributaries devastated Billings, Montana. Despite the vulnerability of the community that this event revealed, the floodplain was not accurately delineated for decades. The reason for this delay in mapping was due to two factors: 1) lack of available funding and 2) exceedingly complex flow patterns in the developed floodplain. ...

  • New study assesses the global volume and distribution of “modern” groundwater

    Groundwater has long been an important resource for spraying, drinking water, energy production and more, but getting a clear picture of how much is available and being recharged over time has been a challenge.

  • Did you know? Part 2: Water Scarcity

    Water scarcity is among the main problems to be faced by many societies and the World in the 21st century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water. Water scarcity already affects every continent. ...
