Selham is a small village and former civil parish, now in the parish of Graffham, in the Chichester district of West Sussex, England. It lies south of the A272 road 3 miles (4.8 km) east of Midhurst. It is mainly in the parish of Graffham, but partly in that of Lodsworth to the north. In 1931 the parish had a population of 65.
The nearest watercourse on the river map is the River Rother, about 10 m from the middle of Selham's gauges. It flows into the River Arun about 15 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Rother nearest the middle of Selham's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
Selham is monitored by 1 Environment Agency river level station on the River Rother, in West Sussex. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.

No recorded flood outline is mapped around the Selham town centre means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. FloodRadar has separately logged 10 flood warnings or alerts for the West Sussex area since February 2026. See the flood history link below.
