Abstract:
A Radar rainfall preprocessing, calibration, forecasting, catchment
averaging and display system for hydrological use.
IH has recently integrated its radar rainfall preprocessing,
calibration, forecasting and catchment averaging procedures into
a single software package. HYRAD employs these procedures as the Radar Hydrology Kernel
of a workstation-based radar data reception processing and a Windows 3.1 display system.
The system supports the following functions:
- radar preprocessing to correct for static anomalies and transient clutter
- radar calibration by raingauges
- radar rainfall forecasting, using either calibrated or uncalibrated fields
- calculation of rainfall fields from raingauage network alone
- calculation of catchment average rainfalls from uncalibrated, calibrated or forecast radar rainfall or raingauge network data
- static and rapid replay of radar images (uncalibrated, calibrated or forecast)
along with overlay information on raingauge location, river networks, catchment
boundaries, coastlines and other feature data
- real-time reception of 2km, 5km network and other radar data types
- a radar data archiving facility
- an interface to the RFFS (River Flow Forecasting System).
For VAX/VMS (or Unix) applications a client-server architecture is used in which the
Radar Hydrology Kernel and data reception and archiving software runs on a VAX/VMS or
Unix machine. A PC running Windows 3.1 or later is used to support the Graphical User
Interface and visualisation facilities.
