Hydrology Studio

Hydrology Software for Stormwater Modeling

Design Detention Ponds the Easy Way

From complex watershed modeling to pre- and post-development drainage studies with detention ponds, we make stormwater modeling a breeze. Hydrology Studio software is simple to use and free to download and try. Get started today!

Model Watersheds and Design Detention Ponds

Model multiple systems in a single project with up to 100 hydrograph nodes, with up to 8 return periods... simultaneously. And it's coupled with a delightful user interface.

Time-Tested Methodologies

Design and analyze using well-known methodologies that comply with industry standards and local regulations. NRCS, Rational and Modified Rational methods are built-in along with an extensive library of design storms and rainfall. Easily customize to match your local standards and regulations.

Use State-of-the-Art Design Procedures

We include many cutting-edge design procedures and wizard-like processes that get you from point A to B in the fewest steps. We work hard to eliminate guesswork with graphically rich, real-time interactions that keep you pointed in the right direction.

Easily Customize to Match Your Local Rainfall

Hydrology Studio contains ready-to-use design storms including SCS Types I, IA, II, Fla Mod, III, Std 6-hr, NRCS MSE, NOAA, NRCC, CA, Huff, Indiana Huff and IDF-based balanced or nested. Imports rainfall directly from NOAA Atlas 14.

Rainfall Wizard Imports Directly From NOAA Atlas 14

You can create IDF curves and customize the rainfall for your SCS/NRCS design storms in just three simple steps.

Choose Your Location on the NOAA Map

Move a cross-hair to your exact site location. A button-click is all it takes to download the rainfall data used to develop IDF curves and serve all SCS or NRCS design storms.

Import the Data Directly Into Hydrology Studio

NOAA rainfall is easily imported and your new IDF curves will be created and displayed right in front of you. Optionally add your own correction factors, Cf, to account for saturation.

Use a Library of Built-in Dimensionless Design Storms

Select from one of 80 built-in design storm distributions. Plus, there's no need to fuss with external files. Storms are hard-coded or created on demand.

Design Your Next Detention Pond in 15 Minutes

Hydrology Studio employs a wizard that gets you from post-development back to pre in 3 easy steps. It estimates storage eliminating guesswork. Offers a graphically oriented, real-time interactive trial-routing tool. Satisfies peak Q and volumetric detention criteria.

Step 1. Estimate Required Storage

Hydrology Studio will quickly estimate required storage volumes so you can build your detention pond to the correct size the first time around. No guesswork!

Step 2. Create Your Detention Pond

Build your new detention pond to the correct size. Enter or import contour areas from your CAD software, select trapezoid shaped, manufactured underground chambers or manual entry.

Step 3. Add Outlet Structures

Hydrology Studio has developed an incredible breakthrough in detention pond outlet structures. It develops a Target Stage-Discharge for each return period and overlays it on a Schematic drawing for you to use as a guide when adding outlet devices. It’s fast, direct and eliminates iterations.

Your Design is Completed in Less Than 15 Minutes

Real-time interaction with a realistic schematic drawing of your pond’s outlet structures during Step 3 is the key ingredient to your success.

Design Underground Stormwater Detention Basins

Hydrology Studio has features that allow you to model underground stormwater detention systems. Use generic or select from a built-in library of manufactured storage chambers. 

An Easy 3-Step Process

Step 1 determines the storage required using pre and post development hydrographs and target release rates. In the final step the software provides you with a dedicated outlet structure made just for underground detention.

Create the Most Efficient Chamber Layouts

For Step 2 you’ll select your chamber system from your preferred manufacturer and lay out the system to match your target storage. Use an interactive tool to set the number of chambers and rows. A manufacturer-specific layout is instantly drawn right before you indicating the dimensions and total storage.

Design Your Chamber Outlet Structure

The software automatically inserts a Riser structure for which you can add outlet devices such as a weir wall, orifice, exfiltration and outlet culvert. Perform trial pond routings along the way until it’s done exactly the way you need it.

Easy to Understand Reports Make You Look Good

Designed to be easily read and understood by you, reviewers and colleagues. These are the reports that will make you proud to hand out your business card. And it makes reviewers feel good about approving.

Best-in-Class Professional looking Reports

Report types range from recaps & summaries to scalable detailed reports and worksheets. Just check the options you like on a print menu and Hydrology Studio starts printing easy-to-read reports for any or all return periods.
