2Coarse gravel is less than 60mm in diameter. A clay loam and coarse gravel mix is unlikely to form very good grass cover.

For flows over easily eroded soils, whether they are bare or vegetated, reduce velocities by 20% (that is, multiply suggested velocity by 0.80).

The Department of Primary Industries and Regional Development recommends using professional advice to design surface water management structures.

The table below provides suggested maximum velocities of surface water flow on various soils. This information can be used when designing surface water management structures.

Note: this information is a general guide, and local conditions need to be assessed before designing surface water management structures. Managers should use specialist advice for their site.

Where grass cover is very good and suitable groundcover can be maintained, water velocities can exceed 1.5 metres per second (m/s). See Table 1.
