Table Name: Hydrological Information
Group: HIT (Hydrology-related Tables)
Type: Data entry table. A table used to input the information for new records.
General Description:
This table stores detailed hydrological characteristics associated with each palaeoflood record. These include estimated discharges, paleowater depths, velocities, and the methods which those values were obtained.

Fields:
- idh (hydrological identifier): Primary key and unique code for each hydrological interpretation in the database.
- ID_REG (Record Identifier): Foreign key linking the hydrological information to a palaeoflood record.
- PN (Palaeolevel Altitude): Estimated altitude reached by the flood water level (in meters above sea level).
- PF (Water Depth): Estimated water depth during the flood event (in meters).
- PV (Flow Velocity): Estimated speed of the water flow (in meters per second).
- TQ (Discharge Data Type): Indicates whether the discharge value is exact, minimum, maximum, or a range.
- Q (Estimated Discharge): Estimated flow of the flood event in cubic meters per second.
- RQS, RQI (Discharge Range Limits): Upper and lower bounds of the discharge estimation range, if not exact.
- MQ (Discharge Estimation Method): Method used to calculate discharge, e.g., Manning's equation, 1D or 2D hydraulic modeling.
- IQ (Discharge Uncertainty): Any uncertainty or margin of error related to the discharge estimation.
- QH (Other Hydrological Data): Additional qualitative or quantitative hydrological interpretations.
- FT (Flood Type): Classification of the flood type (e.g., flash flood, hyperconcentrated flow, debris flow).
- STT (Stream Type): Description of the river type at the location of the evidence.
- QA (Specific Discharge): Discharge / Area.

Relationships:
- This table is linked to the Record Basic Data table (BIT group) via a foreign key (ID_REG).
