I’m excited to announce the release of the latest version of STE, packed with tools that make flood and sediment modeling even more powerful and effortless.
Here’s what’s new 👇
⚙️ STE Downloader
Downloading STE is now fully automated.
With STE Downloader, users can download and install the latest version directly within the software. It ensures every user always works with the most up-to-date and stable version of STE.
📈 Return Period Analyzer
This is one of the most important new tools in STEGIS.
Flood frequency analysis is a fundamental part of hydrology — and now it’s fully integrated into STEGIS.
The Return Period Analyzer can estimate the return period of discharge, precipitation, or even water surface elevation using robust statistical methods like Gumbel, Log-Pearson Type III, and GEV L-Moments.
Having this capability directly inside STEGIS means no more exporting data to external software. Analysts can now compute return periods, visualize frequency curves, and immediately apply the results in flood modeling — all in one connected environment.
🧮 Raster Calculator
A fast, independent, and flexible tool for spatial analysis.
The new Raster Calculator allows users to create custom rasters or perform mathematical operations between multiple rasters using user-defined equations.
Unlike typical raster calculators, this one is built to work seamlessly with STEGIS layers, ensuring speed, reliability, and full control over raster processing.
🌄 Elevation Harmonizer
Previously part of the “Merge Rasters” tool, Elevation Harmonizer is now a standalone, intelligent module.
Why separate it? Because synchronization deserves its own engine.
It automatically adjusts elevation differences between DEMs to create smooth transitions — ensuring continuity across model boundaries without manual correction.
This split makes the tool more flexible, faster, and easier to maintain for large-scale terrain preparation workflows.
💧 Enhanced Real-Time Watershed Delineator
The Real-Time Watershed Delineator has been upgraded with new options for speed, precision, and customization.
Whether you’re defining catchments or analyzing hydrologic response, it now runs faster and adapts better to varying DEM resolutions and flow conditions.
🌐 Stage–Area–Volume Relation Extractor (Enhanced)
A small but powerful upgrade — selecting an elevation in the Stage–Area–Volume table now highlights its corresponding inundation extent on the map in real time.
This makes it easier than ever to visualize storage capacity and flood levels interactively.
Each of these features represents another step toward making flood and sediment modeling easier, faster, and more integrated than ever before. 🌊
