PROJECT APPROACH , <br />Riverside possesses a .full data archive of the SNODAS data back to October 2003 and receives a <br />daily feed of the hourly and daily data grids from NOHRSC. <br />Riverside will use existing tools to design a fully automated process that downloads and <br />processes the data for display in the Flood DSS map server. A second process will be developed <br />to create data products using the historical data archive, if these data products are deemed useful <br />during the needs assessment. The process requirements will include downloading and <br />processing the data files, renaming the files, and deleting or archiving the oldest data file. <br />Deliverables <br />1. Flood DSS website with automated processes to integrate the SNODAS, SNOTEL, and <br />Flood Threat Bulletin into the Flood DSS <br />2. Administrator and user documentation for the Flood Outlook features in the Flood DSS, <br />which allow State staff to configure and maintain the system, and users to effectively use the <br />system features. <br />4.6.3 Implementation of Link to Satellite Monitoring System Alert System <br />(SMSAS) <br />Goals <br />Link the Flood DSS to the SMSAS to provide flood alerts based on real-time data that are <br />collected by the State. Implement appropriate data management, analysis, and display features to <br />provide timely information related to potential or actual flood conditions. <br />Background <br />The SMS Alert System (SMSAS) is an additional component developed by DWR to detect <br />critical conditions -such as low and high flows. The system allows for configuration of the <br />criteria and notification of registered users. The system allows low flow conditions to be <br />monitored for the Instream Flow DSS and high flow conditions to be monitored for flooding. <br />The existing system has limitations that may require additional development.. For example, the <br />system does not generate alarms for combinations of criteria, such as high flow and high rate of <br />change in flow. <br />Approach <br />During the project kickoff meeting, Riverside will work with the CWCB to identify the needs <br />-and requirements of the Flood DSS related to the SMSAS. In particular, topics will include <br />determining the form of data products, update frequency, and notification method that is most <br />appropriate. <br />Riverside will meet with State of Colorado staff to understand the current SMSAS design and <br />features, as well as enhancements that might be implemented during the project. <br />Riverside will evaluate whether previous integration efforts, such as on the Instream Flow DSS, <br />remain applicable, or whether a different approach is needed. Riverside will: <br />• Determine an overall design to generate products for the Flood DSS. <br />• Determine whether more complex analysis is needed (e.g., analyzing flow rate and change in <br />rate, including precipitation and temperature data in the analysis, or comparing data at <br />neighboring stations). <br />DNR RFP PDA-923 50 R ~ V E R S ~ ~ E <br />~i <br /> <br />ii <br /> <br /> <br /> <br /> <br /> <br />~i <br />~i <br />u <br />u <br />u <br />n <br />n <br />n <br />
