Designing combination of natural infrastructures to improve flood mitigation in the Brazos basin.
Abstract
New smart infrastructure investment is needed to combat impact of rising climate extremes, and aging gray infrastructures. One of the upcoming strategies is use of natural infrastructures, such as wetlands, forest, etc. Research is needed on how to plan combination of different types of natural infrastructure to maximize flood mitigation in the basin. To test this, we use hydrologic model (the Variable Infiltration Capacity, VIC) and the hydrodynamic model (the CaMa-Flood, CMF) and a test basin (the Brazos basin in Texas). We use parameters for already calibrated VIC and we calibrated CaMa-Flood using streamflow data and by tweaking river parameters. Using this modeling framework, we performed experiments of different combination of wetland and forest cover in the Brazos basin. We found that strategic combination of both land use land cover (LULC) change resulted in reduction in the flood reaching mouth of the basin. Further we compared it with individual LULC change, we found that combination resulted in more flood peak reduction in the Brazos basin.
