The TARSO model was specifically designed for this. Have you tried that? |

ThresholdTransform can be seen as a system with a different storage coefficient above a certain groundwater level, for example when there is surface water above ground level in wet periods. No extra water is removed, and the response times do not change. The initial idea was that there could be multiple thresholds, but right now there can only be one threshold (nparam =2). TarsoModel can be seen as a system with two different drainage system, where the top drainage system becomes active above a certain groundwater level. Groundwater is removed more quickly above this level, and the reponse time of your model changes. This stressmodel is more appropriate for your case. However, as TarsoModel needs to know the groundwater level, the groundwater level is calculated by the stressmodel itself, and there cannot be any other influences, like a well, in the current implementation. So I think you have to live with the disadvantages of the stressmodel/transform you choose... Improving ThresholdTransform so there can be multiple thresholds might improve the simulated values above ground-level. This may physically not be the right solution, however. |
