  • Development of method for X-band weather radar calibration

    Calibration of the X-band LAWR (Local Area Weather Radar) is traditionally based on an assumed linear relation between the LAWR radar output and the rainfall intensity. However, closer inspection of the data reveal that the validity of this linear assumption is doubtful. Previous studies of this type of weather radar have also illustrated that the radar commonly has difficulties in estimating ...

  • Assimilation of weather radar and binary ubiquitous sensor measurements for quantitative precipitation estimation

    Assimilation of data from heterogeneous sensors and sensor networks is critical for achieving accurate measurements of environmental processes at the time and space scales necessary to improve forecasting and decision-making. Owing to different measurement accuracies and types of spatial and/or temporal measurement support of the component sensors, it is often unclear how best to combine these ...

  • Improved wet weather wastewater influent modelling at Viikinmäki WWTP by on-line weather radar information

    Municipal wastewater treatment plant (WWTP) influent is typically dependent on diurnal variation of urban production of liquid waste, infiltration of stormwater runoff and groundwater infiltration. During wet weather conditions the infiltration phenomenon typically increases the risk of overflows in the sewer system as well as the risk of having to bypass the WWTP. Combined sewer infrastructure ...

  • Evaluating the accuracy of C- and X-band weather radars and their application for stream flow simulation

    This paper investigates the accuracy of rainfall estimates from C- and X-band weather radars and their application for stream flow simulation. Different adjustment procedures are applied to raw radar estimates using gauge readings from a network of 12 raingauges. The stream flow is simulated for the 48.17 km2 Molenbeek/Parkbeek catchment located in the Flemish region of Belgium based on a lumped ...

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...

  • Long-term evaluation of gauge-adjusted precipitation estimates from a radar in Norway

    The implementation of weather radars in Norway by the Norwegian Meteorological Institute (met.no) has made radar a potential tool to improve hydrologic predictions through the use of distributed precipitation input. Met.no supplies gauge-adjusted quantitative hourly radar precipitation estimates. A key concern regarding the use of radar precipitation estimates in hydrology is their accuracy. In ...

  • Seismic reflection, seismic crosshole and ground penetrating radar case study

    Geophysical Investigation of the Crosstown Expressway. Tampa, FL In April, 2004 Pier 97 which supported an elevated roadway in Tampa, FL was vertically displaced (collapsed) approximately 10 feet (ft). At the time of the collapse it was not known whether the collapse was associated with geological conditions at the site, specifically karst conditions, or whether is was associated with a ...

  • How better weather forecasting can help stretch water supplies

    Reservoir managers look to storm predictions to make smarter choices about dam operations Last year, New York City faced an unusual situation. An epic winter in the city’s Delaware River watershed brought heavy snow and very little rain. Stubborn cold meant there was no snowmelt to refill water-supply reservoirs, even as the city’s 9.5 million residents were draining them dry. A ...

  • Comparison of short-term rainfall forecasts for model-based flow prediction in urban drainage systems

    Forecast-based flow prediction in drainage systems can be used to implement real-time control of drainage systems. This study compares two different types of rainfall forecast – a radar rainfall extrapolation-based nowcast model and a numerical weather prediction model. The models are applied as input to an urban runoff model predicting the inlet flow to a waste water treatment plant. The ...

  • Development of the Stormwater Information System that protects life and property from floods

    The Stormwater Information System distributes storm pump operating conditions, etc. to residents in real time via the Internet utilizing a private network that employs optical fibers installed in sewer pipes. Information to be distributed includes advisory and warning information relating to weather data, weather radar information, river information, emergency disaster information, refuge maps, ...

  • Big data and hydroinformatics

    Big data is popular in the areas of computer science, commerce and bioinformatics, but is in an early stage in hydroinformatics. Big data is originated from the extremely large datasets that cannot be processed in tolerable elapsed time with the traditional data processing methods. Using the analogy from the object-oriented programming, big data should be considered as objects encompassing the ...

  • Evaluation of a near-real time NEXRAD DSP product in evolution of heavy rain events on the Upper Guadalupe River Basin, Texas

    This study evaluates the Next Generation Weather Radar (NEXRAD) Digital Storm-Total Precipitation product (DSP) by analyzing 30 rain events on the Upper Guadalupe River Basin, Texas, from September 2006 to May 2007. The DSP product provides relatively accurate information on the evolution of rain events at high spatial and temporal resolutions in near-real time. This is particularly important ...

  • Monitoring network for Scottish ports - Case Studies

    Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...
