  • Extending HydroShare to enable hydrologic time series data as social media

    The Consortium of Universities for the Advancement of Hydrologic Science Inc. (CUAHSI) hydrologic information system (HIS) is a widely used service oriented system for time series data management. While this system is intended to empower the hydrologic sciences community with better data storage and distribution, it lacks support for the kind of ‘Web 2.0’ collaboration and social-networking ...

  • 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 ...

  • A recipe for standards-based data sharing using open source software and low-cost electronics

    Environmental data are critical to understanding environmental phenomena, yet their consistent collection and curation can be cost-prohibitive. This paper describes a recipe for the design, development, and deployment of a low-cost environmental data logging and transmission system for environmental sensors and its connection to an open source data-sharing network. The hardware is built using ...

  • HydroUnits: supporting dimensional analysis in hydrologic computing systems using sensor-based standards

    Unit representation in the Transducer Electronic Data Sheet (TEDS) specified in the IEEE 1451 standards is a binary sequence of 10 octets that encode the physical units as a product of the seven Système International base units, plus radian and steradian, each raised to a rational power in addition to an unsigned integer indicating the structure of the unit. While this representation seems ...

  • State-wide collection of site remediation data in support of environmental quality objectives

    Geographic Information Systems (GIS) hold great potential as a tool for managing environmental site remediation data. While noting the location of contaminated sites in GIS is commonplace, GIS has played only a minor role in review and analysis of chemical data gathered during an investigation or monitoring activity. The New Jersey Department of Environmental Protection Site Remediation Branch ...

  • New Jersey Uses GIS, EQuIS to Collect Site Remediation Data

    Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...

  • System dynamics simulation of soil water resources with data support from the Yucheng Comprehensive Experimental Station, North China

    System dynamics (SD) is one of the most suitable methods available to simulate and quantify the behaviour of complex systems due to it non-linear, multivariable, information feedback and temporally changing characteristics. This paper has improved on Khan et al.'s established model (see Khan et al. (2009) ‘Analyzing complex behavior of hydrological systems ...

  • Calculation of the far range atmospheric transport of radionuclides after the Fukushima accident with the atmospheric dispersion model MATCH of the JRODOS system

    The paper presents estimates of the far-range atmospheric dispersion of radionuclides after the accident at Fukushima Daiichi Nuclear Power Plant (NPP), obtained using the long-range atmospheric dispersion model MATCH. Software tools were developed to run MATCH in the EU nuclear emergency response system JRODOS using freely available numerical weather prediction (NWP) data of the Global ...

  • Comparison of autoregressive moving average and state space methods for monthly time series modelling of Labrador and South-East Quebec river flows

    Time series data such as monthly stream flows can be modelled using time series methods and then used to simulate or forecast flows for short term planning. Two methods of time series modelling were reviewed and compared: the well-known auto regressive moving average (ARMA) method and the state-space time-series (SSTS) method. ARMA has been used in hydrology to model and simulate flows with ...
