About the company
Joshua E Asarian, operating as Riverbend Sciences, a self-certified small disadvantaged business sole proprietorship based in Eureka, California, provides River Basin Model 10 (RBM10) thermal and hydrologic analysis and water temperature modeling consulting to the Department of the Interior as a prime contractor under Total Small Business set-asides. The vendor holds three recent federal awards totaling $180 thousand in combined potential value, all with the U.S. Geological Survey Office of Acquisitions and Grants (two awards, $166 thousand) and the Bureau of Reclamation (one award, $13 thousand).
Riverbend Sciences' capability footprint centers on RBM10 model development, calibration, validation, and scenario analysis for dam removal and water release impact assessment in the Klamath River and Trinity River basins. Recent work includes a $126,500 purchase order (September 2024, performance through December 2027) from USGS to update the Klamath River Basin RBM10 model structure, improve model inputs, calibrate and validate the updated model, and evaluate effects of Lewiston Dam releases on lower Klamath River temperatures; a $39,900 purchase order (August 2026, performance through December 2027) from USGS to compile post-dam removal water temperature data from 2024–2026 for RBM10 calibration and validation, execute counterfactual thermal regime scenarios, and deliver a peer-reviewed manuscript with supplementary materials and regional science conference presentation (minimum three years of RBM10 modeling experience required); and a $13,358 firm fixed price purchase order (August 2022, completed August 2023) from the Bureau of Reclamation to refine tributary flow and temperature inputs to RBM10 and improve gap-filling methods for temperature measurements in support of Trinity River water allocation management and salmon habitat evaluation.
Customer concentration is concentrated within Interior Department water resource management functions. One hundred percent of awards fund USGS and Bureau of Reclamation programs, with USGS accounting for two awards and $166 thousand combined potential value. Two awards totaling $166 thousand reach ultimate completion within the next twenty-four months, creating recompete exposure in that window. No subcontractor relationships are present in the source data; all awards are prime contractor work. The vendor competes exclusively under small business set-asides (Total Small Business and self-certification as a small disadvantaged business), with no presence on government-wide vehicles or multi-award IDIQs.
