Numerical codes developed by Leon's research group

Arturo Leon and his research group developed the following numerical codes.

 

Illinois Transient Model (ITM)

(New) The current version of ITM was developed at University of Houston, Texas.

This model is intended for simulating transient free surface flows, transient pressurized flows and the simultaneous occurrence of free surface and pressurized flows in complex closed-conduit systems. In the ITM model the free surface region is modeled using the 1D Saint-Venant equations and the pressurized region is modeled using the 1D compressible waterhammer equations. The ITM model can simulate complex boundaries such as dropshafts, reservoirs, rating curves, gates and junctions with any number of inflowing and outflowing pipes.

Hydropower Calculator V. 1.1

Hydropower Calculator is a Matlab code intended to facilitate the calculations for determining optimal flow discharge and optimal penstock diameter when designing impulse and reaction turbines for hydropower systems. For the Matlab code and the associated journal paper click here

 

Flows in Pipe Networks V. 1.0

Flows in Pipe Networks is a Matlab Code for computing flow discharges and pressures in complex pipe networks (unlimited number of pipes). This code can also handle any number of pumps. For more information about Flows in Pipe Networks click here

 

Annel2 V. 1.3

Annel2 is a Matlab Code for computing steady water surface profiles in circular and trapezoidal channels in series. For more information about Annel 2 click here

 

OSU Rivers

OSU Rivers is intended for the intelligent control of complex regulated river systems, such as those that have multiple reservoirs, have multiple objectives and in which the flow dynamics of the system is of particular interest. OSU Rivers will be made open source (free and open access) under the terms of the GNU General Public License aspublished by the Free Software Foundation (http://www.gnu.org/licenses/gpl.html). News about OSU Rivers coming soon.

 

Controlling HEC-RAS using Matlab

The Journal paper below has only some of the scripts and due to space limitations, not all scripts in the Journal are complete.

Urban Flooding Model (UFM)

Code for modeling overland flows, street flows, Curb-and-grate inlet flows and pipe flows (July 2008-August 2009). For the street and pipe flows a Finite volume-shock-capturing scheme was used.
