# Channels

There are a number of SWAT+ files that control the simulation of channel processes. The file  [**channel-lte.cha**](channels/channel-lte.cha) summarizes the main channel information and references several other files that specify the details:

* [**initial.cha**](channels/initial.cha) references several files, which specify the initial contents of nutrients and constituents in the water,
* [**hyd-sed-lte.cha**](channels/hyd-sed-lte.cha) controls the channel hydrology and sediment properties, and
* [**nutrients.cha**](channels/nutrients.cha) controls the channel nutrient properties.&#x20;
