Modeling of complex sediment processes using experimental data and laboratory measurements
How can insights from focused laboratory experiments be used to inform hydraulic and sediment transport models for improved predictions of complex sedimentation processes?
Can unsteady flow and sediment characteristics be used to formulate quantitative dependencies between turbulent flow models and sediment transport models?
Can unsteady flow, vegetation, and sediment characteristics be used to formulate quantitative dependencies between turbulent flow models and sediment transport models under vegetated flow conditions?
How can collaborations with academic researchers in the field of ecohydraulics be most fruitful in supporting the Reclamation mission and advancing state of the art capabilities?
Need and Benefit
Increasing priority placed on balancing the function of ecosystems and water infrastructure necessitates continued development of tools that can better predict the effects of complex ecohydraulic processes related to sediment transport in the riparian environment. Understanding transport of sediment is also critical to the design of river restoration strategies that involve the engineered manipulation of channel geometry and riparian vegetation. Quantitative understanding of linkages between vegetation and sediment transport is necessary in order to design sustainable river restoration projects.
The key to improving Reclamation's capabilities in simulating complex sedimentation processes lies in improving quantitative predictive tools. Reclamation is poised to become a pioneering agency in river restoration design and analysis. Reclamation engineers will be able to design and build more sustainable and effective river restoration strategies.
