RainMaps\u2122 is an incredible cloud-based server that houses the specific rainfall files for Hydrology Studio Suite. Normally, you would have to manually input the data or import it from NOAA Atlas 14, but we’ve done all the hard work for you. With just a few clicks of your mouse, these files are readily accessible to you.<\/p>\n\n\n\n

We selected hundreds of cities across the U.S. with populations greater than 50,000. We then extracted the precipitation and intensity data for each city directly from NOAA Atlas 14 Precipitation Frequency Data Server<\/a>. This data was then imported into Hydrology Studio and processed to create the final IDF Curves (.idf). These are ready-to-use files for which you can open and start using in your software. No need to import or manually enter any data.<\/p>\n\n\n\n

What\u2019s more is that your Rational method flows will be generated using the latest hydrometeorological data. Note that these files can be downloaded and opened in Hydrology Studio, Stormwater Studio, Culvert Studio and Studio Express.<\/p>\n\n\n\n

How to Get Your Local Rainfall Files<\/h2>\n\n\n\n

Open the Rainfall Wizard from the Main Window by clicking on the Rainfall button.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Then click the RainMaps button on the Rainfall Wizard toolbar as shown below.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This opens Hydrology Studio’s online RainMaps<\/a>\u2122 page in your default internet browser.<\/p>\n\n\n \t\t

\r\n \t\t\tTip<\/span> \t\t\t \t\t\t\t

\r\n \t\t\t\t\tRainMaps\u2122 can also be accessed directly from hydrologystudio.com<\/a>. \t\t\t\t<\/p>\r\n \t\t\t \t\t\t\r\n \t\t<\/div>\r\n \t\t\n\n\n\n

You’ll first see a map of the United States including Alaska and Hawaii.<\/p>\n\n\n

\n
\"\"
Click on your desired state. Note that states OR & WA are not yet included in the NOAA project data and thus are not included in RainMaps.<\/figcaption><\/figure><\/div>\n\n\n

Select Your State<\/h3>\n\n\n\n

Click on your desired state. This loads a larger map of the selected state with the available cities. The example below shows South Carolina. Each city contains rainfall .idf files.<\/p>\n\n\n

\n
\"\"
Use the control buttons at the upper right to zoom in or out.<\/figcaption><\/figure><\/div>\n\n\n

Select Your City<\/h3>\n\n\n\n

Click on the city closest to your project area. From the ensuing pop-up lightbox, click the IDF Curves<\/strong> button to download the associated IDF curves (.idf) file.<\/p>\n\n\n

\n
\"\"
Click the IDF Curves button to download the .idf file.<\/figcaption><\/figure><\/div>\n\n\n

These files will typically be sent to your PC’s Downloads folder. We recommend moving them to your dedicated Rainfall folder. Once downloaded and moved to your desired folder, they are ready to be used in any Hydrology Studio software.<\/p>\n\n\n\n

Open the IDF Curves<\/h3>\n\n\n\n

Click Open button in the Rainfall Wizard as shown below.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Navigate to the downloaded .idf file, for example, CharlestonSC.idf, and click Open. You’ll then see the resulting IDF Curves on the Graph tab chart. The IDF curves are ready to use.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Now close the Rainfall Wizard and return back to the Main Window. Your peak flows will now be generated using this data. These files will automatically open upon each program launch so there’s no need for you to return here.<\/p>\n\n\n\n
