Hydrological transport model
An hydrological transport model is a mathematical model used to simulate river or stream flow and calculate water quality parameters. These models generally came into use in the 1960s and 1970s when demand for numerical forecasting of water quality was driven by environmental legislation, and at...
has also been applied in a large number of catchments on most continents.
Discharge Modelling
This is the major application of HBV, and has gone through much refinement. It comprises the following routines:- Snow routine
- Soil moisture routine
- Response function
- Routing routine
HBV has been used for discharge modelling in many countries worldwide, including Brazil

Sediment and Solute Modelling
The HBV model can also simulate the riverine transport of sediment and dissolved solids. Lidén simulated the transport of nitrogenNitrogen
Nitrogen is a chemical element that has the symbol N, atomic number of 7 and atomic mass 14.00674 u. Elemental nitrogen is a colorless, odorless, tasteless, and mostly inert diatomic gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere...

Sediment
Sediment is naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of fluids such as wind, water, or ice, and/or by the force of gravity acting on the particle itself....
