What Wikipedia says

A nilometer is a structure for measuring the Nile River's clarity and water level during the annual flood season in Egypt. There were three main types of nilometers, calibrated in Egyptian cubits: (1) a vertical column, (2) a corridor stairway of steps leading down to the Nile, and (3) a deep well with a culvert.
