Soil moisture assimilation in urban watersheds: A method to identify the limiting imperviousness threshold based on watershed characteristics

Data assimilation is well suited for merging observed and simulated values to improve hydrologic forecasts. Typically, observation data that is assimilated into hydrologic models can be obtained from in situ gauges, radar, and remote sensing. In an urban environment, the benefits of soil moisture assimilation are not clearly defined. This work aims to identify the feasible imperviousness range at which it is advantageous to assimilate remotely …
