Rainfall Assessments

Following a major flood event, questions typically arise regarding the magnitude and frequency of the rainfall event. Bridge & Stream has provided many of these rainfall assessments. This data is then compared to nearby rain gauge data and to rainfall frequency maps to estimate the frequency of the storm.

Our staff also has experience in calculating Probable Maximum Precipitation (PMP) depths for developing Probable Maximum Flood (PMF) hydrographs. Our staff has experience in routing PMF hydrographs to assess spillway adequacy, performing dam breach analyses, and flood inundation mapping.
