2 years ago @hhrhrhehxcshdfsrg, I haven't personally dedicated much effort to the influence of the spatial resolution of the runoff dataset on the quality of discharge computations. I usually just make sure that the runoff grid is coarser than the catchment sizes, and then apply a simple centroid-based transformation (see https://doi.org/10.1016/j.envsoft.2012.12.011). There are also other transformation options (for example: https://doi.org/10.1016/j.envsoft.2018.05.018). But I agree that evaluating the impact of the runoff resolution would be an interesting endeavor.
What would you like to ask?
The runoff data grid size used in my model is 5km for computational power reasons. I use MERIT data to build a rapid model. I know that the finer the grid size, the better the simulation may be. But I would like to ask whether the coarse grid resolution has a great influence on the calculation results? Have you done any research on this?
