Even under current sea level conditions, many communities are working to protect their coastlines against flooding and shoreline erosion. Coastal often shorelines excessive erosion by using armoring techniques (e.g., bulkheads, riprap). Yet hardened structures reduce of the natural adaptive mechanisms present in coastal ecosystems sustainability system. In contrast, nature-based features living...
Bank habitats provide important functions for riverine fish. Yet, they have been heavily modified by land use, technical flood protection measures, and hydropower installations. Fish species requiring specific to complete their life cycle strongly declined therefore become target of river restoration measures. This study compared abiotic conditions fish community composition three bank habitat ...
For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....
Windows TM Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of embankment dams. These software components are being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap...
Protecting coastal communities has become increasingly important as their populations grow, resulting in increased demand for engineered shore protection and hardening of over 50% of many urban shorelines. Shoreline hardening is recognized to reduce ecosystem services that coastal populations rely on, but the amount of hardened coastline continues to grow in many ecologically important coastal ...
Windows Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of dams. WinDAM is being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap to delay or prevent failure of th...
