# msk\_x The weighting factor is a function of the wedge storage. This parameter is only important if channel routing is simulated using the Muskingum routing method. {% hint style="info" %} For reservoir-type storage, there is no wedge and *msk\_x* should be 0.0. For a full-wedge, *msk\_x* should be 0.5. For rivers, *msk\_x* will fall between 0.0 and 0.3 with a mean value near 0.2. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://swatplus.gitbook.io/io-docs/~/changes/GiVD5ID0WVyRIAumaMy2/introduction/basin-1/parameters.bsn/msk_x.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
