3.2 Data Types

CHPS uses two types of data – static and dynamic. CHPS is a location-oriented system, which means CHPS uses the static input data to orient its dynamic data. CHPS pulls in dynamic data in order to make forecasts.

Dynamic Data

As the name implies, dynamic data changes. Examples of dynamic data used in hydrologic forecasting are river stage, precipitation, and pool elevation.

See the other sections in this lesson for information on setting how long the data resides in the system, how much precision you store the data in, and how the data is synchronized on the system.
