Abstract EN
Roughness length is one of the key variables in micrometeorological studies and environmental studies in regards to describing development of cities and urban environments.
By utilizing the three dimensions ultrasonic anemometer installed at Mustansiriyah university, we determined the rate of the height of the rough elements (trees, buildings and bridges) to the surrounding area of the university for a radius of 1 km.
After this, we calculated the zero-plane displacement length of eight sections and calculated the length of surface roughness.
The results proved that the ranges of the variables above are ZH (9.2-13.8) m, Zd (4.3-8.1) m and Zo (0.24-0.48) m.
