InfoSWMM, H2OMAP SWMM, InfoSWMM SA Fully Supports the EPA SWMM-CAT Climate Change Adjustment Tool

Introduction

The Innovyze products InfoSWMM and H2OMAP SWMM are always based on the current version of EPA SWMM 5 (the current version is 5.1.010) and we are pleased to announce that the current version of both InfoSWMM and H2OMAP SWMM (v14) is also able to use the output of the EPA’s Storm Water Management Model Climate Adjustment Tool (SWMM-CAT) to help our users estimate future changes in temperature, evaporation, and rainfall for their simulation modeling.

The Storm Water Management Model Climate Adjustment Tool (SWMM-CAT) is a new addition to EPA SWMM 5 and also to InfoSWMM and H2OMAP SWMM. It is a simple to use software utility that allows future climate change projections to be incorporated into SWMM  5, InfoSWMM and H2OMAP SWMM. The SWMM-CAT tool provides a set of location-specific adjustments that derived from global climate change models run as part of the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project Phase 3 (CMIP3) archive. These are the same climate change simulations that helped inform the United Nations Intergovernmental Panel on Climate Change in preparing its Fourth Assessment report.  SWMM-CAT and the EPA  Stormwater Calculator for Low Impact Development simulation are both a part of the President’s Climate Action Plan.

“Climate change threatens our health, our economy, and our environment,” said Gina McCarthy, EPA Administrator. “As part of the President’s Climate Action Plan, this tool will help us better prepare for climate impacts by helping build safer, sustainable, and more resilient water infrastructure.”

The continued development of predictive modeling tools such as SWMM 5, InfoSWMM and H2OMAP SWMM will provide urban planners and other stakeholders with the resources they need to incorporate both traditional stormwater and wastewater system technologies with the emerging, innovative techniques of green infrastructure. The collective impact will be more sustainable urban areas and healthier waterways across the nation.

SWMM-CAT is very easy to use with InfoSWMM and H2OMAP SWMM

SWMM-CAT is very easy to use with InfoSWMM and H2OMAP SWMM. First, download the SWMM-CAT program and then simply enter your watershed’s Zip Code, Future Projection Period and Future Climate Change outcome (Figure 1). The Monthly Hot Dry/Median Change/Warm-Wet estimates are then estimated for Temperature (Figure 1), Evaporation (Figure 2) and Rainfall (Figure 3). The Monthly Adjustment Factors are then saved to a SWMM5 INP File (Figure 4), imported into either InfoSWMM or H2OMAP SWMM (Figure 5) and used in Future Scenario’s as part of the Climatology Settings (Figure 6). The monthly adjustments can be used to simulate llong-termchanges in the climate as shown for an example 1000 year simulation (Figure 7) or analyzed using the InfoSWMM or H2OMAP SWMM Output Statistics Manager (Figure 8).
