Short summary
We present and validate BrAHMs (BAsal Hydrology Model): a new physically based basal hydrology model, which captures the two main types of subglacial drainage systems (high-pressure distributed systems and low-pressure channelized systems). BrAHMs is designed for continental glacial cycle scale contexts, for which computational speed is essential. This speed is accomplished, in part, by numerical methods novel to basal hydrology contexts.
