Year: 3500 BCType: Water Level MeasurementTypical use: AgricultureThe annual flood season along the Nile was unpredictable without records, so the Egyptians created a flood gauge called the Nilometer.
The simplest design was a vertical column submerged in the river with marked intervals indicating the depth of the river. A second design was a flight of stairs leading into the river.
The nilometer data was then used by the ancient Egyptian priesthood who mystically predicted when the flood would occur. |
