Generation and Delivery of Meteorological and Hydrological Forecasts for the Green River Basin

1. Scope of Work. The services rendered under this delivery order will be provided during a Base Year with four (4) Option Years as identified in the Period of Performance in Section 6. The provider shall generate and deliver to the Seattle District, U. S. Army Corps of Engineers (NWS), meteorological and hydrological forecasts for the Green River basin of Washington State and graphical images for selected outputs from the extended Weather Research and Forecast model (version 3.5.1 or later) coupled with the National Weather Service Global Forecast System forecast model (WRF-GFS) and the European Center for Medium Range Weather Forecasting forecast model (WRF-ECMWF) at a regional scale. As noted in Section 2, the services to be delivered under this contract are separated into three distinct products (designated as CLIN 0001, CLIN 0002, and CLIN 0003 in Section 2). The services to be delivered under CLIN 0001 are the calibration of the hydrological model used for streamflow forecasts. CLIN 0001 is only applicable to the base year of the contract period. The services to be delivered under CLIN 0002 are the generation and delivery of meteorological and hydrological forecasts for the Green River basin. The forecasts will be generated using a high-resolution weather prediction model coupled with a distributed hydrologic model specifically calibrated to the Green River basin. The collective modeling system (weather prediction model and hydrologic model) will be used to provide short-range meteorological and hydrological (streamflow) forecasts to NWS on a daily basis for a four-month period beginning 1 November and ending 28 February during each contract award performance period. Forecast information delivered to NWS will include quantitative precipitation forecasts (QPF’s) for selected locations within the Green and White River basins and other pre-determined sites within Washington State as defined by the current regional meteorological model. The provider will also deliver to NWS streamflow forecasts for total runoff into Howard Hanson reservoir (reservoir inflow), total runoff from the Soos Creek basin, total local runoff entering the Green River between Howard Hanson dam and the Green River at Auburn USGS gaging station (this includes runoff from the Soos Creek basin), and natural (unregulated) flow in the Green River at the Auburn USGS gage. Forecast information will be updated at least four times daily during the duration of the service period. Forecast information will be provided to NWS via a password protected website and via a secure ftp site. The provider will have available two separate dedicated “T1” lines to transmit forecast information to their internet site to ensure that the forecast information can be made available at all times to NWS.

The services to be delivered under CLIN 0003 are the generation and delivery of graphical images showing specified output from two different global models (WRF-GFS; WRF-ECMWF). Forecast graphical images will be provided to NWS on a daily basis (updated at least twice daily) for a 12-month period beginning 1 August and ending 31 July during each contract award performance period. Forecast information will be provided to NWS via website.

A more detailed summary of the deliverable forecast information covered under this scope of work is presented in Section 2. Other pertinent information relative to this scope of work is described in Sections 3-5. A Period of Performance is provided in Section 6.

2. Services to be performed by the provider. The provider will supply services under this scope of work as noted below:

a. CLN 0001 Hydrological model calibration. The Distributed-Hydrology-Soil-Vegetation Model (DHSVM, University of Washington) will be used to generate hydrological forecasts. Prior to the flood season (Nov. 1) during the base year of the contract, the model will be calibrated using historical hydrological and meteorological observations publicly available and provided by NWS. These observations include hourly station based temperature and precipitation, stream discharge, and snow water equivalence (SWE) at SNOTEL observation locations (NRCS). The model will be calibrated to accurately represent streamflow response to precipitation and snowmelt, and snow accumulation and melt timing. Locations for model calibration and validation include inflow to Howard Hanson reservoir, streamflow at Soos Creek near Auburn, WA (USGS 12112600), and SWE at Cougar Mountain, Lynn Lake, and Sawmill Ridge. In addition, a methodology for determining the optimal model state for which to start simulations from for forecast time periods will be included as a component in model calibration. The determination of this initial state will utilize real-time observations in the basin from the period leading up to the forecast period.

b. CLIN 0002

i. Delivery of meteorological forecasts. The weather prediction model used to generate these forecasts is the Weather Research and Forecast model driven with two global weather models (WRF-GFS and WRF-ECMWF). Meteorological forecast information delivered to NWS will include quantitative precipitation forecasts (QPF’s) for up to five locations within the Green River basin, four locations within the White River basin, and other pre-determined sites within Washington State as defined by the provider’s regional meteorological models (see list of desired QPF locations in Table 1). QPF information will be delivered to NWS based on output from two forecast products for each model.

One forecast product will provide QPF information and temperature for roughly a 7-day forecast window (7 days less about four hours) and the second forecast product will provide QPF information and temperature for roughly a 60-hour forecast window. All types of QPF products will provide forecast precipitation at an hourly time-step histogram, with WRF-GFS superimposed onto WRF-ECMWF. QPF’s will be updated at least once daily for the 7-day forecast product. For the 60-hour forecast product, updates with the WRF-GFS are needed four times daily and with the WRF-ECMWF updates are needed two times per day. Furthermore, the 60-hour QPF product from the WRF-GFS may be updated more than four times per day if certain streamflow thresholds are exceeded. In addition, High Resolution Rapid Refresh (HRRR) forecast hourly precipitation QPF’s, updated hourly, would also be provided. Forecast information will be provided to NWS via a password protected website and via a secure ftp site. The provider will have available two separate dedicated “T1” lines to transmit forecast information to their internet site to ensure that the forecast information can be made available at all times to NWS.

g3ct9gtf Highlight

ii. Delivery of hydrological forecasts. Meteorological input to the DHSVM model for forecasted time periods will be derived from output from the WRF-GFS and WRF- ECMWF weather forecast models. Hydrologic forecast information delivered to NWS will consist of streamflow forecasts for total runoff into Howard Hanson reservoir (reservoir inflow), total runoff from the Soos Creek basin, total local runoff entering the Green River between Howard Hanson dam and the Green River at Auburn USGS gaging station (this includes runoff from the Soos Creek basin), and natural (unregulated) flow in the Green River at the Auburn USGS gage. Hydrologic forecasts will be delivered to NWS based on output from the two forecast products. Both forecast products will provide forecasted streamflow at an hourly time-step. Hydrologic forecasts will be updated at least once daily (7-day forecast product) or at least two to four times daily (60-hour forecast product for WRF-GFS, 4x daily; WRF-ECMWF, 2x daily). Visualizations for each of the 7-day and 60-hour hydrologic products will include forecasts from the WRF-GFS and WRF-ECMWF driven hydrologic simulations on the same plots for comparison. Forecast information will be provided to NWS via a password protected website and via a secure ftp site as discussed under Item “b.” above.

The Government (NWS) will provide the vendor with available real-time meteorologic and hydrologic data from the Green River basin for the purpose of adjusting the hydrologic model to current conditions for which to initialize the model state for the forecast period. The following data will be provided by NWS to the provider:

Precipitation, air temperature, and wind speed from the Ravensdale meteorological station; precipitation and air temperature from the Howard Hanson dam meteorological station; precipitation and air temperature from the Mud Mountain dam (ENUW) meteorological station; precipitation and air temperature from the Lester meteorological station; computed inflow to Howard Hanson reservoir, observed discharge from Howard Hanson reservoir, observed discharge from the Green River at Auburn gaging station, and observed discharge from the Newaukum Creek gaging station. Hourly values for these parameters will be sent to the provider on an hourly basis during the duration of the period of the service agreement. Transmitted parameter values will be time-stamped using Greenwich Mean Time (GMT).
