Hydrologic Parameter Effects on Small‐Dam Risk Analysis in Missouri
Publication: Journal of Irrigation and Drainage Engineering
Volume 116, Issue 4
Abstract
The sensitivity of risk cost to hydrologic parameters is evaluated to determine the feasibility of risk analysis as an alternative to existing requirements for rehabilitation at small dams in Missouri. The sensitivity to probable maximum precipitation (PMP) exceedence probability is greatly reduced by interpolating rainfall exceedence probabilities between the PMP and the rainfall depth that initiates failure, instead of the PMP and the 100‐year return period depth. This approach also reduces by a small amount the sensitivity of risk cost to the assumed probability‐distribution function. Variations in the time distribution of rainfall and the antecedent moisture condition (AMC) have a large influence on risk cost. Probabilistic combinations of the three AMC classes result in risk costs within 13% of the risk cost using AMC II, the “average” condition. Of the three dam‐breach parameters evaluated, risk cost is most sensitive to breach‐development time and least sensitive to breach side slopes.
