Simulation Modeling to Secure Environmental Flows in a Diversion Modified Flow Regime

摘要: AbstractThis paper describes the development and application of a spreadsheet model to evaluate effects water management on diversion modified flow regimes, enabling exploration novel ways meet proposed environmental standards. Mill Creek, northern California river with an altered regime that impacts aquatic species, was used as case study. Test cases examined how alternatives, such groundwater pumping, rights transfers, exchange agreements, can improve allocations given irrigation demands. Four test include passage flows for Chinook salmon steelhead trout, minimum instream flow, 80% natural spring recession functional components. The identified late October consistently water-scarce, even in wet years. These analyses suggest fall shortages fish migration could be eliminated through agreement combined use wells. All except mi...
