Tulvalta

Tulvalta is a Finnish grammatical form derived from the noun tulva, meaning a flood. It represents the elative or ablative case of tulva and is used to indicate source or origin in phrases describing flooding. In ordinary language the form is rarely treated as an independent concept; in technical or legal texts it appears to specify what comes from or is caused by a flood.

In practical usage, tulvalta appears in compound and phrasal expressions that describe effects, content, or origins related to flooding. Examples include phrases such as tulvalta aiheutuva vahinko (damage caused by flooding) or tulvalta peräisin oleva vesi (water originating from the flood). The form also participates in compound terms used in hydrology, disaster management, and planning discussions to refer to aspects tied to floods, such as risk, exposure, or damage originating from a flood event. It is common in Finnish scientific and regulatory writing to combine tulvalta with other elements to form descriptors for flood-related phenomena.

Etymologically, tulvalta is formed from tulva (flood) plus the elative suffix -lta/-ltä, which marks origin or source. The use of this form reflects Finnish patterns of indicating source material or cause in technical language, rather than introducing a standalone semantic entry.
