{{CSDMS meeting abstract template 2025
|CSDMS meeting abstract=Rainfall intensity thresholds are used to estimate when postfire debris flows may occur in the western US. Prior research has shown that postfire debris flows are highly correlated with short-duration rainfall intensity, and that short duration rainfall thresholds (e.g., 15-minute rainfall intensity) can be estimated based on wildfire and terrain attributes. Consequently, it is possible to determine possible debris flow activity in recent burn areas in the western United States by tracking rainfall rates using publicly available rainfall data. We have developed a software (FlowAlert) and an accompanying map dashboard that monitors when and where rain gages near burn areas cross rainfall intensity thresholds. The software runs continuously on a linux server, processing more than 2500 rain gages every two hours. When rainfall rates near a burn area are higher than a rainfall threshold, symbols are updated on a map indicating possible debris flow activity. Rainfall plots are also provided on the dashboard, and via email alerts for the gages that have crossed the rainfall intensity threshold. FlowAlert can be used for situational awareness to alert authorities of potential debris flow activity in remote areas. Additionally, the data stream produced by FlowAlert can be used by managers to adjust the rainfall intensity threshold in areas following storms based on observed activity. For example, if rainfall thresholds were crossed, but no debris flows were observed, managers may choose to increase the rainfall threshold to avoid warning fatigue. This presentation will focus on the utility of the new FlowAlert software, and how it might be used for decision support in burn areas.

{{Process description model
|Describe processes represented by the model=This code will erode cells according to a shear stress and also deposit sediment based on the concentration of sediment in a modeled water column. Additionally it has a headcut that migrates upstream and as the headcut erodes it deposits sediment downstream that the model must erode.
|Describe key physical parameters and equations=manning's n for vegetation
manning's n for soil
critical shear stress for vegetation
critical shear stress for soil
rainfall
infiltration
|Describe length scale and resolution constraints=This works for channels of hundreds of meters with 1 m cells
|Describe time scale and resolution constraints=It is typically run for times no less than 25 years and no greater than 700 years.
|Describe any numerical limitations and issues=Numerical instabilities occur if the time step is too large.

It provides information about a stream including, knickpoint locations, Elevation/distance that can be used to create longitudinal profiles, XYvalues of all the cells in a stream path, etc. The tool uses built-in tools for ArcGIS 10.x (so you must run this on a machine with ArcGIS 10.x installed), but it is written in python. I used it with a 1m LiDAR DEM, so I'm not totally sure how well it will pick out knickpoints on coarser gridded DEMs.
