Data that can be used in calculations are called data settings. Each kind of data that can be used has a data setting identifier with a position, data classification, unit and standard deviation.

Coupling to the model

Data that can be used in calculations are called data settings. Each kind of data that can be used has a data setting identifier with a position, data classification, unit and standard deviation. This way PROTIDE knows what it can do with the data.

Position

The position refers to the geographical location the data applies to. Because PROTIDE only knows given locations along the channel, each position refers to one of these channel positions.

Data classification

The data classification tells PROTIDE in which order to use the data. This means that if there are several data settings available for the same position and unit for a certain time, PROTIDE chooses the one with the lowest "order in calculation".

Unit

The unit indicates the type of data. It can be one of the following:
  • Water level
  • Water speed
  • Water direction
  • Swell
  • Wave height

Standard deviation

The standard deviation of a data setting indicates the variability of the actual value around the given prediction. For example, if a prediction of the water level is +1 meter and the standard deviation is 0.2 meter, then PROTIDE assumes that the actual water level (at the given position and time) has a normal distribution with mean +1 meter and standard deviation 0.2 meter.
