HSEB AHPS
Software Development Mission:
To support the OHD mission, we work with other OHD teams, universities,
public agencies and private organizations to integrate and develop
science and technology. We deliver software and provide support
primarily to NWS River Forecast Centers (RFCs).

What we do: The
Advanced Hydrologic Prediction Service (AHPS) is an integrated real
time modeling and data management/analysis system. It provides new
information and products created through the infusion of new science
and technology. This service will significantly improve flood forecasting
and water management in the United States for periods from days
to several months into the future.
We support the RFCs through
the design, development, testing, enhancement, implementation, and
support of the National Weather Service River Forecast System (NWSRFS).
The advances provide:
1. Critical software
enhancements to the NWSRFS;
2. Effective calibration
and field-implementation of advanced hydrologic/hydraulic models
within the NWSRFS;
3. The nucleus of capabilities
to handle the integration of real-time/historical station and gridded
data, and model generated (forecast) outputs;
4. The use of short-
to long-range weather and climate forecasts within the NWSRFS through
hydrometeorologic coupling algorithms.
Software Applications
Supported: We primarily support the NWSRFS which consists of
the following components:
1. Calibration System
(CS): Generates time series based on historical data and determines
model parameters. The ICP is a graphical interface to display
the observed and simulated streamflow values and the IDMA is an
interactive tool for conducting double mass analysis.
Supported Programs: MAP, MCP3, MAT, OPT3, PXPP, TAPLOT, IDMA
and ICP
2. Forecast System (FS):
Uses calibrated parameter values to generate short-term river and
flood forecasts and maintain model state variables. The Interactive
Forecast Program (IFP) is a graphical user interface to display
the model outputs for an area and a time period.
Supported Programs: ESPINIT, FCINIT, FCST, FILECRAT, FILESIZE, GOESDB,
PPDUTIL, PPINIT, PRDUTIL, REORDER, SASMDB, SHEFPARS, SHEFPOST and
the IFP.
3. Ensemble Streamflow
Prediction System (ESP): Uses current model states and an ensemble
of time series to generate an ensemble of hydrographs and probabilistic
short or long-term forecasts.
Supported Programs: ESPADP, ENS_PRE, ENS_POST, ESPVS, BATCHBUILDER
4. Data Visualization:
These programs provide data quality control tools, data editing
tools, and interactive forecast preparation tools.
Supported Programs: XDAT, XNAV, XSETS
5. RFC Forecast Verification:
These programs compute statistics on matched pairs of observations
and forecasts.
Supported Programs: VERIFY, IVP
6. The NWS Flash Flood
Guidance System (FFGS): Includes techniques and programs for
computing flash flood guidance.
Supported Programs: FFGUID, PRODGEN, ZGRID |
