New Events Editor In EPA SWMM 5.1.011 and InfoSWMM Non Steady Period Dialog
If selected and the change in lateral inflow or node volume or node depth is higher that the defined tolerance for any single node in the collection system, then hydraulic routing will be conducted, otherwise the steady state condition will be assumed. (See Improved Dry Weather Computation Efficiency for more information.)
Skip Steady State Period - Select to skip steady state period and use the tolerances below or leave blank to use internal default tolerances. (Note: Internal default tolerance: Lateral Inflow = 0.00001 cfs, Node Depth = 0.00001 ft, Node Volume = 0.01 ft3.)
Lateral Inflow Tolerance - minimum change in lateral inflow per simulation timestep for hydraulic routing to be performed.

Graphical View of the Runoff process in #SWMM5 and #INFOSWMM
Immerse yourself in the vibrant, non-linear world of runoff processes with InfoSWMM and SWMM5, where every drop of rain and every grain of soil tells a story of hydrological complexity. 🌧️🌿🔍
Explore the Runoff Realm: Your journey begins with the varied landscapes of runoff surfaces, each with its own character:
- The hard, storage-savvy impervious surfaces 🏙️
- The absorbent, life-giving pervious grounds 🌱
- The slick, unyielding impervious zones without depression storage 🛣️
Navigate the Terrain: Traverse slopes identical across terrains and witness how width shapes the subcatchment's hydrological response. 🏞️📐
Infiltrate the Infiltration Puzzle: Decipher the infiltration enigma with methods ranging from Horton to Green-Ampt, each nuanced by climate change's monthly adjustments. 💧🕵️♂️
Evaporation - Nature's Algorithm: Engage with evaporation, nature's algorithm, modulated by constants, series, and even the rhythm of the seasons, all under the watchful eye of climate change. ☀️💨
The Roughness Factor: Feel the surface beneath your feet, from the sleek impervious to the textured pervious, each with its unique roughness coefficient. 🚶♂️🌳
Depression Storage - Nature's Reservoirs: Discover the pockets of storage across your urban and natural landscapes, critical in the initial interception of rainfall. 🛤️🌼
The Chill of Snowmelt: Brace against the chill of snowmelt, guided by temperature readings and wind speeds from climate files or time series, all fine-tuned for a changing world. ❄️🌡️
The Web of Water Processes: Weave through the intricate web of connected water processes, from LID controls that mimic nature to the groundwater's silent flow, the transformation of snow to water, and the dance of water quality constituents. 💦🌐
Where Waters Flow: Follow the water as it journeys to nodes, pervious surfaces, other subcatchments, or through LID controls like rain gardens and green roofs, each a story of ingenuity and design. 🌈🏞️
The Drama of Rainfall: And finally, gaze skyward to the drama of rainfall, from design storms to historical patterns, enriched by long-term data and user-created sagas, all under the shadow of climate change. 🌦️📖
This is the mosaic of runoff processes in InfoSWMM and SWMM5—a symphony of hydrological phenomena waiting for you to conduct its performance. 🎶🌍📚
