# Category: Venant

## Overview

In this blog we example the St Venant terms used in SWMM5 as equations, table, graphs and units.  We use a QA/QC version of SWMM 5 that lists many more link, node, system and Subcatchment variables than the default SWMM 5 GUI and engine.  This also applies to #InfoSWMM

## SWMM5 Upstream Weighting

Purpose: The purpose of this note is to explain a significant dynamic wave routing difference between EPA SWMM 5.0.013 and EPA SWMM 5.0.011 and before. A few people have detected a difference. The previous solution(s) would use only the midpoint area (Amid) and hydraulic radius (Rmid) Read the rest

## The four cross sectional areas in a link of SWMM 5 and InfoSWMM

Note: Four cross sectional areas are used in a link of SWMM 5. The weighted hydraulic radius (Rwtd) is a function of the Froude Number of the link and the upstream and downstream hydraulic radius. The Rwtd value is used in the computation of the friction slope or Read the rest
