We need to map the lateral flows (q_lat) for each NWM v2.1 segment to the refactored stream network. This may require partitioning/aggregating flows from multiple segments.

Eventually we will need to use this method to reroute q_lat from short headwater streams that are removed from the refactored network as a post processing step.

• for each NWM v2.1 segment, use the crosswalk to map q_lat time series to the appropriate refactored segment(s)
• generate a new csv with q_lat time series for every segment in the refactored network
• generate a crosswalk file that tracks how the flows were partitioned/aggregated between networks

Provide estimate of computational resources needed to develop a refactored hydrofabric for the entire NWM domain.

Update the routing module/testing configuration to support diffusive wave testing on refactored networks.

Develop a workflow for comparing Courant Number violations between datasets.

Requested outputs:

• CN violations, total segment count; timesteps
• min, max, average, median stream segment length for the original and refactored networks
• check number of unique segments that violate CN (control for multiple time step violations)
• % of stream network by length with CN violations over period of time
• network order -- (bin by order) -> get clarification from @jameshalgren
