This issue contains the National Interoperability Flood Experiment II featured collection as well as several other technical papers.

Featured Collection – National Flood Interoperability Experiment II (NIFE II)

The NIFE II featured collection presents seven papers that – 1) evaluate the outputs from the continental-scale flood forecast modeling system with field data and results from other hydrologic models; 2) discuss certain data driven approaches as alternative or complementary approaches to the national data model; and 3) illustrate how streamflow forecasts can be extended to flood mapping and damage assessment.

In the Introduction, Nelson provides a synopsis of the seven papers of the NIFE II featured collection.  Model evaluation studies include the paper by Salas et al. who demonstrate the three month nowcasting capabilities of a continental scale streamflow simulation and forecast system implemented through the National Flood Interoperability Experiment.  Quintero and Krajewski compare streamflow predictions from the Hillslope Link Model operated by Iowa Flood Center and the National Water Model operated by the National Water Center of NOAA.  Finally, Lin et al. assess a large-scale hydrologic modeling framework (WRF-Hydro-RAPID) for simulating evapotranspiration and streamflow over Texas.

Data driven modeling approaches include the paper by Petty and Dhingra who demonstrate the reliability of machine learning approaches to predict streamflows at inoperable gages.  Zhao et al. use statistical and hybrid statistical and physics-based models in conjunction with web applications to predict reservoir inflows during flood events. Selvanathan et al. illustrate a hydraulic analysis methodology to estimate national level floodplain changes due to climate change.  Gutenson et al. illustrate the utility of Flood Damage Wizard tool to estimate flood damage using approximate fuzzy text matching functions to illustrate how streamflow forecasts can be used in flood management.

Additional Technical Papers

Sadeghi et al. develop and test a method for optimally selecting and sizing stormwater control measures in urban landscapes.

Schifman et al. highlight the utility of EPA National Stormwater Calculator as a screening tool for assessing site runoff dynamics and stormwater management.

Kang and Sridhar assess the impacts of climate change on severity and intensity of future droughts in the Chesapeake Bay Watershed and emphasize the need for using multiple drought evaluation methods using both precipitation and temperature.

Ennenbach et al., based on a national county-scale evaluation, indicate roof based rainwater harvesting has the potential to augment water supplies for urban and suburban uses across the US and especially in counties of the Pacific Northwest, Central, and Eastern regions of the nation.
