Simulation Results: Maxima vs TVD

source: github Introduction When reviewing the simulation results, there are two sections TVD and Maxima. Maxima is generated during the simulation, the simulation engine will keep track of the maxima for all the result parameters at every computation time step. TVD is the saved time series which reports the values at…

Gridded Rainfall: More accurate rainfall

source: github Introduction Spatially varying rainfall in InfoWorks ICM help to improve the rainfall spatial accuracy. You can add spatially varying rainfall into InfoWorks ICM using a Rainfall Event or Spatial Time Series Database. A rainfall event object records rainfall for a network of rain gauges. Each gauge has a…

How to effectively manage simulation results in ICM

source: Innovyze support Portal Some ICM models can produce large results datasets — sometimes in the order of tens or even hundreds of GBs per simulation. Large results datasets can lead to storage or file access issues. In this article we’ll discuss strategies to manage the size of modelling results…

How to model river in SWMM/XPSWMM

source: github Introduction SWMM/XPSWMM is a widely used software that utilizes a node-link scheme for modeling drainage networks, particularly for underground pipe systems. While this scheme works well for such networks, it becomes challenging when modeling open channels or culverts since these objects do not have physical nodes in the real…

How to batch import subcatchments into XPSWMM from external data source

source: github Introduction When building large hydrology models, you might find it easier to prepare the subcatchments input parameters in GIS or CAD software. Two commonly used methods to get external data into XPSWMM are “import from GIS” and “GIS Link”. Most users are familiar with the “import from GIS”, but…

SWMM5 Infiltration Methods Comparison

Source: github Introduction The runoff from pervious areas can be highly dependent on the infiltration settings used in models like SWMM. To ensure accurate results, SWMM infiltration methods have undergone several major updates. The choice of infiltration methods in SWMM5 are the modified Green Ampt, Modified Horton, and CN methods, all…

Evaporation

source: github Introduction Evaporation usually is not a significant source of loss for models running a single design storm for system capacity analysis. However, for continuous simulation with a focus on water volume and quality, it can have significant impact on the modeling results. Evaporation happens when there is standing water…

Quickly Identify and Remove Illegal Characters in Your Large Text Files

When working with modeling software packages like XPSWMM or SWMM, text files are often used to store the models. Even software that uses a database to store the model, like InfoWorks ICM, may still use text files as an exchange format. As the size of the model grows, the text…
