Key Concepts

Best Fit Line

A best fit line is a statistical tool used in regression analysis to model the relationship between two variables. In hydrology, plotting discharge values against their corresponding recurrence intervals and fitting a line allows for estimation and prediction of discharge at unobserved recurrence intervals through interpolation or extrapolation.

Discharge

Discharge refers to the volume of water flowing through a river or channel per unit time, typically measured in cubic feet per second (cfs). In the context of flood frequency analysis, understanding discharge values at different recurrence intervals is critical for risk assessment and the planning of flood control measures.

Recurrence Interval

A recurrence interval, also known as the return period, is a statistical estimate of the average time between occurrences of an event, such as a flood. This concept helps engineers and hydrologists design infrastructure and plan for extreme events by quantifying the likelihood of a particular discharge or water level being exceeded in any given year.
