Long-throated flumes and broad-crested weirs are becoming the preferred measuring devices for use in irrigation canals. A computer program for calibrating these flumes and weirs has been available since the early 1980s. But because the flume dimensions were program inputs, design was largely by trial and error. FLUME 3.0 is a new computer program that not only provides flume calibrations, but also assists the user with flume design. Design criteria include submergence, accuracy, freeboard, and Froude number limitations. The first two criterion are examined at both high and low flow rates to assure proper performance of the structure throughout the range of flows to be expected. FLUME 3.0 is menu driven for easy use and maintains a database of flume designs and as-builts. The program also has graphical-data entry screens so that profile and cross-section dimensions can be visually verified. This helps the user to avoid errors in data entry. FLUME 3.0 is available along with a user's manual through the International Institute for Land Reclamation and Improvement or through Water Resources Publications.
