Abstract. Water erosion was recorded between mid-October and mid-December 1989 in 31 out of 73 erosion-susceptible arable fields being monitored in England and Wales. Most fields were drilled to winter cereals. Tramlines and wheelings were the factors most commonly linked with initiation of erosion, particularly where runoff was concentrated on valley floors or headlands. Lack of crop cover (〈 15%) was also an important factor at a number of sites; 25–30% ground cover was generally sufficient to protect the soils from erosion. Erosion was initiated by rainfall events of 15 mm or more in a 24 h period, with a maximum intensity greater than 4 mm/h. A large erosion event in south-west England was associated with 33 mm of rainfall in 4.25 h, with a maximum intensity of 22 mm/h.
