This is the hydraulics & hydrology software I really needed

Remember that time when your client had an on-the-spot question you couldn’t answer right away? Or when you wanted to do some spot-checking and you didn’t have the time to set up a complete drainage system? What you really wanted was a simple hydraulic calculator tool to do quick pipe, open channel, orifice, weir, inlet and other hydrology calculations, on the fly.

Enter Studio Express. An all-new hydraulics and hydrology software that saves time and makes you look sharp when time is not an option. It’s the perfect companion to Hydrology Studio and Stormwater Studio.

It Begins With a Very Simple User Interface

Like all Hydrology Studio products, it was designed to be as easy to use as it is beautiful to look at, but also fast. It makes you more productive with your time, instead of wasting your time with endless and confusing dialog boxes.

Select a channel, weir, orifice or pipe shape, inlet type or hydrograph method with your mouse. Enter a few data items and you’re done.

Use it once and you’ll be hooked. Hands down, it will be the Studio Express icon you’ll be clicking on first. It’ll be your hydraulics and hydrology tool of choice on every project because it’s dead simple to use.

It Ends Providing Answers You Were Looking For

And plenty of answers you’ll get. A whole range of them in fact. Any of which you can turn into the industry’s finest graphics with a single mouse click. Another mouse click produces a professional looking hydraulics report for your files. Output tables can be exported to spreadsheet files for further processing.

Model and Design Open Channels & Pipes

Analyze and design a variety of open channels for normal depth. User-defined parameters include total depth, bottom widths, side-slopes and bed slope.

  • Rectangular
  • Trapezoidal
  • Triangular
  • Parabolic
  • User-Defined

Input user-defined open channel shapes with up to 50 station & elevation points including varying n-values across the entire section.

Model closed pipes of the following shapes:

  • Circular
  • Rectangular
  • Elliptical
  • Arch

Design it!

Forget studying some rating curve to get a pipe size or a channel width. Studio Express offers an option to design open channels as well as pipe sizes when inputting a known design flow rate.

Weir Flow Calculator

Weirs can be calculated for any range of flow rates. Options include a user-defined tailwater for weir submergence calculations and an adjustable Datum.

  • Rectangular (sharp and broad-crested)
  • Trapezoidal
  • Cipoletti
  • V-Notch
  • Compound (two-stage)

It provides plenty of graphs and other outputs that include:

  • Section
  • Profile
  • Plan
  • Grid-style Numerical Output
  • Rating Table
  • Printed Report

Projectile motion concepts are employed for determining the distance the weir’s free-flow travels.

Orifice Flow Calculator

Designed to be analyzed with minimal inputs. Options include a user-defined tailwater for submerged orifice calculations and an adjustable Datum.

  • Circular
  • Rectangular
  • Perforated plates

Outputs include:

  • Section
  • Profile
  • Grid-style Numerical Output
  • Rating Table
  • Printed Report

Projectile motion concepts are applied for determining the distance the orifice free-flow jet travels.

Model Storm Drain Inlets

Following the methodology of FHWA HEC-22 inlets, Studio Express calculates interception capacity, bypass and spreads at both the face of the inlet and just upstream of the inlet (gutter). Inlet flows can be specified as a range, single Q or user-defined set.

Studio Express has the ability to analyze up to ten inlets of the following types:

  • Curb (horizontal or inclined throat)
  • Grate
  • Combination
  • Drop Curb
  • Drop Grate

Inlets can be located in a sag or on a longitudinal slope and can be of any size with user-definable gutter and pavement cross-slopes and clogging factors.

Outputs include:

  • Gutter Profiles
  • Inlet Profiles
  • Grid-style Numerical Output
  • Rating Table of Q vs. Spread (Inlet and Gutter)
  • Printed Report

Create Runoff Hydrographs

Use these time-tested methodologies:

  • Rational
  • Modified Rational
  • NRCS

You’ll get built-in calculators for developing composite runoff coefficients and NRCS Curve Numbers. Its built-in Tc calculator computes NRCS Lag, multi-segment TR-55 and Kirpich Tc. NRCS hydrographs include a user-definable Shape Factor.

Studio Express constructs each runoff hydrograph in one-minute time intervals for up to 48-hours. Critical for small drainage areas with BMP or LID requirements to insure proper coverage.

Studio Express comes with ready-to-use dimensionless design storms including:

  • Type I
  • Type IA
  • Type II
  • Type II Fla Modified
  • Type III
  • NRCS Standard 6-hr
  • IDF-based synthetic (1, 2, 3, 6, 12 & 24-hr)

IDF curves can be automatically created from NOAA Atlas 2, 14 or existing rainfall data using the built-in IDF Wizard. Import directly from NOAA.

Outputs include:

  • Hydrograph Plots
  • Grid-style Numerical Output
  • Professional Report
  • Worksheets
  • Rainfall Reports

Estimate Detention Pond Sizes

Need a quick size estimate for a proposed detention pond? Simply enter your target release rate and Studio Express will calculate the total required storage for you.

A printed formal report is available which includes inputs, graph, numerical table and supporting worksheets.
