Designing Watercourse Crossings for Passage of 100-year Flood Flows (938.9 KB)Three methods for making office-based estimates of 100-year recurrence-interval streamflows for ungaged basins are presented: (1) an analytical relationship between storm precipitation, watershed characteristics, and runoff, (2) regional regression equations based on long-term flow records, and (3) flow transference methods that adjust nearby measured discharges for differences in drainage basin size.
