HEC-HMS

HEC-HMS is a great tool for hydrological modeling, which can seem pretty complex at first. There are so many factors to consider, and they can change based on location and time. But don’t worry! This software is designed specifically for running hydrological simulations, especially in dendritic or branched watersheds. It gives users all the tools they need to analyze things like event infiltration, unit hydrographs, and hydrological routing.

Easy Transition from GIS

If you're used to working with GIS software, you'll feel right at home with HEC-HMS! The layout looks a lot like what you’d find in typical GIS programs. You can easily access all your data through the layers panel, and you have the option to tile or maximize your main working area based on what you prefer.

Manage Hydrological Variables

You can create, edit, and manage a bunch of hydrological variables that define your modeling approach. Whether it's watersheds, weather data, or terrain data—everything is manageable!

Customizable Parameters

The best part? HEC-HMS lets you really customize your data! With lots of parameters available and the ability to adjust each one in detail, you get real flexibility. Each parameter has its own module too. Unlike some GIS software that forces you to keep everything in strict order, HEC-HMS offers more freedom.

Processing Time Considerations

Just keep in mind that if you're running simulations with tons of parameters over long periods of time, it might take a while to process—especially if you're not using a dedicated workstation.

A Tool for Everyone

This program is perfect for both newbies and seasoned hydrologists alike! With HEC-HMS at your fingertips, you'll be able to create detailed hydrological simulations for various types of watersheds. Ready to give it a try? You can download HEC-HMS here.
