Abstract: Software for the design of vegetated grassed waterways after the tractive force method of Temple has been developed. The design assumed Bermuda as cover grass with cover factor of 0.9 and stem density of 5380 stem m 2. Also presented the general flow chart for each channel section (trapezoidal, parabolic and triangular) considered. The program was tested using data from literature. The computed design channel depth, d was 0.2 m as against 0.21 m from data (d) and 0.30 m compared to 0.32 m from the data source, the results thus, obtained were satisfactory. The program has the additional advantage of estimating the total cost of establishing the vegetated channel.
