The Fluvial Architecture Knowledge Transfer System (FAKTS) is a relational database storing numerical and descriptive data about fluvial sedimentary architecture coming from fieldwork and peer-reviewed literature, from both modern rivers and ancient successions.
The database encapsulates all the major features of fluvial sedimentary architecture (style of internal organization, geometries, grain size, spatial distribution and reciprocal relationships of genetic units) in a hierarchical fashion, classifying datasets – either in whole or in part – according to both controlling factors (e.g. climate type, tectonic setting), and context-descriptive characteristics (e.g. channel/river pattern, dominant transport mechanism).

Click above for a simplified menu-driven online version, which provides search functionalities relating to depositional- and architectural-element geometry and transition data. Choose this option if you want to undertake basic searches (e.g. dimensional data describing width-to-thickness ratios or transition probabilities between neighbouring architectural elements). See the "user guides" section at the bottom of this page for instructions on use.
Below are sets of pre-prepared outputs for common search queries. Each output (e.g., "cb_t") links to a separate PDF file.

A number of Excel spreadsheets that exemplify FAKTS' output that can be generated by the FRG team upon request are available for download. Some examples of simple summary metrics are provided in the links below. Considerably more sophisticated squeries can be generated based on highly specific queries.
These formatted spreadsheets depict sample results of a range of common queries in a variety of graphed formats.
Contact the FRG-ERG-SMRG team if you wish us to demonstrate how FAKTS can be employed to undertake sophisticated queries relating to aspects of fluvial sedimentology and architecture. We invite you to describe particular questions for which you require data, we can code them as SQL queries, submit them to the database, and return the results to you in spreadsheet form.
