Local hydrologist: burn severity can raise runoff peaks and overwhelm culverts
Marker Platt, a structural and hydrology specialist, told the council that post-fire soils can create larger, faster runoff and higher peak flows; he urged rapid mapping of burn severity and immediate modeling to assess culvert capacities and town drainage.
The full story
Marker Platt presented a hydrology-focused assessment of the three watersheds that feed Kanosh and said the recent fire likely changed runoff characteristics across the entire burned area. Using standard methods (curve-number, Type II storm, 100-year event), he said loss of canopy and increased hydrophobic soils can increase peak runoff and shorten hydrograph times to peak.
