Short summary
Many of the features that either block or channelize flooding are too narrow to represent in conventional hydrodynamic (water flow) models, which must work at wider grid scales. New methods have been developed for identifying important features and representing their effects on blocking or controlling flooding. These methods are automated so that a fine-resolution lidar digital terrain model can be easily processed to a coarser resolution while retaining narrow blocking features.
