The SWMM5 engine uses mean flow as the dry weather flow value (DWF) and not population but does allow weekday, weekend, daily and monthly patterns. You can use these many pattern options to actually use population in the SWMM5 and InfoSWMM dry weather flow tables. Here are the steps as … Read the rest

Innovyze Announces the Retirement of the H2OMAP Modeling Platform with Upgrade Path to More Powerful InfoWater, InfoSewer and InfoSWMM Software
Portland, Oregon, USA, December 3, 2017
Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the planned retirement of the H2
Runoff coefficient is loosely defined as the ratio of runoff to rainfall, and is a function of watershed characteristics including land use, soil type, and slope of the watershed. The value of runoff coefficient ranges between 0.0 and 1.0. A value of 0.0 means that all of the … Read the rest
Example 5. Runoff Water Quality
This example demonstrates how to simulate pollutant buildup and washoff in an urban catchment. The influence of different land uses on pollutant buildup is considered and both Event Mean Concentrations (EMCs) and exponential functions are used to represent the washoff process.
Surface runoff quality is … Read the rest
