The RiverWare model utilizes two-stage stochastic programming with recourse to recommend operations decisions. This method performs trade-offs between reservoir uses including water supply, hydropower, flood control, fisheries, and recreation. Two metrics represented hindcast skill of ensembles generated with the Structure for Unifying Multiple Modeling Alternatives (SUMMA) Model: Continuous Ranked Probability Skill Score (CRPSS), and rank histograms. SUMMA hindcasts were also compared to PyForecast seasonal statistical forecasts disaggregated using a nearest neighbor approach. We focused on operations during the snowmelt runoff period from April through July at Buffalo Bill Reservoir. We valued reservoir benefits in dollars but valuations were highly uncertain due to poor economic data and are likely not useful for this trade-off. Because of uncertainty associated with project benefits estimates, we subjectively examined the RIDM approach utility using SUMMA hindcasts for the period 1999\u20132019. The RIDM approach performed worse than both deterministic operations using the median forecast and historical operations.

The RiverWare model utilizes two-stage stochastic programming with recourse to recommend operations decisions. This method performs trade-offs between reservoir uses including water supply, hydropower, flood control, fisheries, and recreation. Two metrics represented hindcast skill of ensembles generated with the Structure for Unifying Multiple Modeling Alternatives (SUMMA) Model: Continuous Ranked Probability Skill Score (CRPSS), and rank histograms. SUMMA hindcasts were also compared to PyForecast seasonal statistical forecasts disaggregated using a nearest neighbor approach. We focused on operations during the snowmelt runoff period from April through July at Buffalo Bill Reservoir. We valued reservoir benefits in dollars but valuations were highly uncertain due to poor economic data and are likely not useful for this trade-off. Because of uncertainty associated with project benefits estimates, we subjectively examined the RIDM approach utility using SUMMA hindcasts for the period 1999\u20132019. The RIDM approach performed worse than both deterministic operations using the median forecast and historical operations. We believe the RIDM approach is valid and suggest several improvements to the method for future efforts including improving forecast skill and simplifying reservoir use trade-offs.", "itemRecordStatusId":1, "isModeled":false, "hasProfile":false, "disclaimer":"The findings and conclusions of this work are those of the author(s) and do not necessarily represent the views of the Bureau of Reclamation.", "sourceCode":null, "locationSourceCode":null, "externalDataUrl":null, "parameterSourceCode":null, "modelNameSourceCode":null, "temporalStartDate":null, "temporalEndDate":null, "spatialShortDescription":null, "publicationAuthor":"Jordan Lanini, Marketa McGuire", "publicationEditor":null, "publicationPublisher":"Bureau of Reclamation", "publicationPublisherLocation":"Denver, CO, USA", "publicationFirstPublicationDate":"2023-11-15T12:00:00+00:00", "publicationPeriodicalName":null, "publicationSerialNumber":null, "publicationDoi":null, "publicationVolume":null, "publicationIssue":null, "publicationSection":null, "publicationStartPage":null, "publicationEndPage":null, "createDate":"2023-11-14T20:56:19+00:00", "itemType":{ "_id":"RPRT", "definition":"Report", "createDate":"2018-11-28T14:19:59+00:00" }, "matrix":{ "_id":18, "matrix":"N/A", "definition":"Matrix is not applicable to this item", "createDate":"2020-03-26T13:58:55+00:00" }, "spatialGeometry":null, "spatialResolution":null, "spatialTransformation":null, "spatialOpenDataURL":null, "metadataFilePath":null, "binaryFilePath":"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/ST FInal Report- P1881_v4_final_508_rev.pdf", "updateFrequency":{ "_id":14, "updatefrequency":"not planned", "definition":"there are no plans to update the data", "createDate":"2018-11-14T15:17:58+00:00" }, "updateDate":"2025-02-04T13:46:53+00:00", "verticalDatum":null, "dataStructure":"Uploaded file(s)", "itemStructureId":3, "parameterGroup":null, "parameterId":null, "parameterName":null, "parameterUnit":null, "parameterTimestep":null, "parameterTransformation":null }, "type":"CatalogItem", "relationships":{ "catalogRecord":{ "data":[ { "id":"/rise/api/catalog-record/7992", "type":"CatalogRecord" } ] } } } ], "Asset Name (in tessel)":"Buffalo Bill Reservoir", "Total Capacity":646565.0, "Total Capacity Elevation":5393.5, "Active Capacity":604817.0, "Inactive Capacity Elevation":5259.6, "Live Capcity":null, "Dead Capacity":null, "Dead Capacity Elevation":5158.0, "Surcharge Capacity":144645.0, "Maximum Water Surface Elevation":5410.0, "Vertical Datum":null, "Vertical Datum Description":null, "Total Capacity Surface Area":6720.0, "name":"Buffalo Bill Reservoir Dam and Powerplant" }, "id":269, "links":[ { "type":"application/json", "rel":"root", "title":"The landing page of this server as JSON", "href":"https://api.wwdh.internetofwater.app?f=json" }, { "type":"text/html", "rel":"root", "title":"The landing page of this server as HTML", "href":"https://api.wwdh.internetofwater.app?f=html" }, { "rel":"self", "type":"application/geo+json", "title":"This document as JSON", "href":"https://api.wwdh.internetofwater.app/collections/rise-edr/items/269?f=json" }, { "rel":"alternate", "type":"application/ld+json", "title":"This document as RDF (JSON-LD)", "href":"https://api.wwdh.internetofwater.app/collections/rise-edr/items/269?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/rise-edr/items/269?f=html" }, { "rel":"collection", "type":"application/json", "title":"USBR Reclamation Information Sharing Environment (RISE)", "href":"https://api.wwdh.internetofwater.app/collections/rise-edr" } ] }
