“…These discrepancies in model predictions may create imprecise and/or ineffective response strategies for flood and drought mitigation. Our findings suggest that model integration of surface depression would not only improve simulated accuracy in projected future flow regimes but provide a better informed approach for managing surface depressions as low-cost “nature-based solutions” ( Bridgewater, 2018 ; Thorslund et al, 2017 ; Zalewski et al, 2018 ), in addition to the conventional structural measures ( Kundzewicz et al, 2019 ; Tullos, 2018 ).…”

Surface water storage in small yet abundant landscape depressions—including wetlands and other small waterbodies—is largely disregarded in conventional hydrologic modeling practices. No quantitative evidence exists of how their exclusion may lead to potentially inaccurate model projections and understanding of hydrologic dynamics across the world's major river basins. To fill this knowledge gap, we developed the first‐ever major river basin‐scale modeling approach integrating surface depressions and focusing on the 450,000‐km2 Upper Mississippi River Basin (UMRB) in the United States. We applied a novel topography‐based algorithm to estimate areas and volumes of ~455,000 surface depressions (>1 ha) across the UMRB (in addition to lakes and reservoirs) and subsequently aggregated their effects per subbasin. Compared to a “no depression” conventional model, our depression‐integrated model (a) improved streamflow simulation accuracy with increasing upstream abundance of depression storage, (b) significantly altered the spatial patterns and magnitudes of water yields across 315,000 km2 (70%) of the basin area, and (c) provided realistic spatial distributions of rootzone wetness conditions corresponding to satellite‐based data. Results further suggest that storage capacity (i.e., volume) alone does not fully explain depressions' cumulative effects on landscape hydrologic responses. Local (i.e., subbasin level) climatic and geophysical drivers and downstream flowpath‐regulating structures (e.g., reservoirs and dams) influence the extent to which depression storage volume in a subbasin causes hydrologic effects. With these new insights, our study supports the integration of surface depression storage and thereby catalyzes a reassessment of current hydrological modeling and management practices for basin‐scale studies.

“…EE in general and SWB more particularly can also, in certain well-defined situations, complement civil engineering for flood prevention. In such situations, it is actually less expensive to install and manage than a civil engineering structure, and it is better integrated into the landscape [40]. The benefits induced must also be considered because, in contrast to civil engineering works, EE and SWB structures are multi-functional in terms of the benefits procured beyond their protective role.…”

Reconciling erosion control and flood prevention with restoration of diversity is an important challenge for our societies today. However, examples of applications remain rare because practitioners and engineers are searching for more integrated solutions for this kind of situation. New considerations should, therefore, refocus attention on developing innovative actions by raising the question of how best to accommodate the two components. Moreover, little attention has been paid to erosion processes and their control for decreasing floods, although this can largely contribute to this purpose. Merging security with ecology, turning to co-benefits nature-based solutions at the catchment scale, based on the use of local ecological engineering, especially soil and water bioengineering combined with civil engineering, can provide adapted practices for harmonizing flood prevention and erosion control with restoration of biodiversity at the water catchment scale. This kind of approach should be accompanied by proposals for coherent and adapted governance for application of co-benefits nature-based solutions at the catchment and territory scales.

“…To address the above-mentioned problem in urban polluted rivers, sequential sedimentation-biofiltration systems (SSBSs) have been implemented. These systems are designed according to the principles of ecohydrology to enhance the capacity of natural systems to remove environmental pollutants and are considered as nature-based solutions (NBS) 4 , 5 . These eco-friendly systems use a combination of natural processes for water treatment, i.e., sedimentation of solids, absorption of phosphorus, reduction of excessive nitrogen compounds by stimulating denitrification and nitrification processes and phytoremediation.…”

Novel heterotrophic bacterial strains—Bzr02 and Str21, effective in nitrogen transformation, were isolated from sequential sedimentation-biofiltration systems (SSBSs). Bzr02, identified as Citrobacter freundii, removed up to 99.0% of N–NH4 and 70.2% of N–NO3, while Str21, identified as Pseudomonas mandelii, removed up to 98.9% of N–NH4 and 87.7% of N–NO3. The key functional genes napA/narG and hao were detected for Bzr02, confirming its ability to reduce nitrate to nitrite and remove hydroxylamine. Str21 was detected with the genes narG, nirS, norB and nosZ, confirming its potential for complete denitrification process. Nitrogen total balance experiments determined that Bzr02 and Str21 incorporated nitrogen into cell biomass (up to 94.7% and 74.7%, respectively), suggesting that nitrogen assimilation was also an important process occurring simultaneously with denitrification. Based on these results, both strains are suitable candidates for improving nutrient removal efficiencies in nature-based solutions such as SSBSs.
