StreamStats Data-Collection Station Report
Webis a critical step in solving the peak-flow equations. StreamStats uses an automated GIS process to determine drainage basin boundaries from a digital representation of the stream network, a geospatial data set of predetermined drainage boundaries, and a (30-meter) Digital Elevation Model (DEM), which is a regularly spaced grid of elevation values. WebOct 28, 2024 · Peak expiratory flow (PEF, or peak expiratory flow ratio - PEFR) is the maximum speed of air during expiration. The speed depends on three basic parameters: lung volume, strength of the respiratory muscles, and the bronchial diameter. WebPeak-flow regression equations were derived for estimating flows at ungaged stream sites with annual exceedance probabilities from 50 to 0.2 percent. Methods for estimating prediction intervals for the peak-flow regression equations are presented. foot specialist of shreveport bossier
