TEMPEST

TEMPEST is an interactive simulation program for temperature estimation in sewers. It can be used to calculate the dynamics and longitudinal spatial profiles of the wastewater temperature in sewers. Applications range from simple steady state estimations of the changes of the wastewater temperature in a single sewer line to full scale simulations of the dynamics of the wastewater temperature in successive sewer lines with lateral inflows.

Program Availability and Documentation

The current program version of TEMPEST is "Version 1.01". In order to receive the TEMPEST executable file, please send an e-mail to tempest@eawag.ch.
