| **Variable** | **Description** | **Typical value(s)** |
|-------------- |-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |----------------------------- |
| `h_banks` | **Stream-bank height**. This is the thickness of material that must be removed for the river to widen by one unit lateral distance | 1-5 m |
| `S` | **Channel downstream-directed slope**. This is used to compute shear stresses and (if necessary) flow depth from water discharge | 10<sup>-3<\sup> |
| `S` | **Channel downstream-directed slope**. This is used to compute shear stresses and (if necessary) flow depth from water discharge | 10<sup>-3</sup> |
| `tau_crit` | **Critical shear stress required to start eroding muddy banks**. At this stress, the flow begins to be able to detach particles. When set up to perform an **inversion** using data on river widening and past flows, this is one of two key parameters to be estimated. | 1--2 Pa |
| `k_d` | **Erosion-rate coefficient.** This determines the rate of erosion as a function of shear stress above critical. When set up to perform an **inversion** using data on river widening and past flows, this is the other of two key parameters to be estimated. | 10<sup>--6<\sup> m / (Pa s) |

| `lambda_r` | **Nikuradse roughness coefficient** ($$k_s$$) This is used if required to create a stage--discharge relationship | 0.05 |
| `D` | **Bed-material median grain size** Required for rivers with transport-limited banks | 0.002--0.2 m |
