# hyd\_typ The types of hydrographs that can be sent depend on the sending object. The code tot is used for several spatial objects, but its meaning differs between objects. The table below lists the available codes and their definition depending on the type of object. | Code | Object | Definition | | ---- | ------------------------------------- | ------------------------------------------- | | tot | Channel | Streamflow | | tot | Aquifer | Groundwater flow | | tot | Reservoir | Reservoir outflow | | tot | Outlet | Flow at the outlet | | tot | Recall | Flow from point source or inlet | | tot | HRU, Routing Unit | Surface runoff + lateral flow + tile flow | | sur | HRU, Routing Unit | Surface runoff | | lat | HRU, Routing Unit | Lateral flow | | til | HRU, Routing Unit | Tile flow | | rhg | HRU, Routing Unit, aquifer, reservoir | Seepage that recharges the receiving object | --- # 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/introduction-1/connectivity/hru.con/hyd_typ.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. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
