Downloadable DOTD Hydraulics Computer Software

Introduction

The Louisiana Department of Transportation and Development has developed several computer programs for use in hydraulics design. They are being made available to consultants who have contracts with the Department for use with those contracts.

They are based on the guidelines and procedures described in the "LA DOTD Hydraulics Manual", (2011 Edition).

The programs have also been modified to use either English or metric units. The metric conversion factor used for pipe sizes is 1 inch = 25 mm. For other dimensions, the conversion factor used is 1 meter = 39.37 inches. These programs will not convert English units to metric units or metric units to English units. They will, however, enable you to work in either set of units depending on your design needs.

Restrictions and Disclaimer

The HYDR Programs have been developed by the Louisiana Department of Transportation and Development (LA DOTD) for the design of projects conducted by the Department. They are in accordance with the guidelines set in the "LA DOTD Hydraulics Manual" (1987 Edition). They are available upon request to consultants under contract with LA DOTD.

Neither the Louisiana Department of Transportation and Development nor the programmers shall bear any responsibility for any errors that may occur in the use of these programs other than for state projects under contract with the Department.

The Department also retains the right to revise, replace, or terminate the use of these programs at any time.

If there are any questions or problems with the HYDR Programs, please contact the Hydraulics Section at (225) 379-1306.
