Overview

What is RAPID?

The Routing Application for Parallel computatIon of Discharge (RAPID) is a river network routing model. Given external inflow to rivers, this model can compute the flow of water everywhere in river networks made out of many thousands of reaches using a matrix-based version of the Muskingum method.

Core Capabilities

RAPID provides the following capabilities:

• River Network Routing: Computes discharge for thousands of river reaches simultaneously
• Matrix-Based Muskingum Method: Efficient sparse matrix implementation for fast computation
• NetCDF4 I/O: Reads and writes scientific data in standard NetCDF format
• Flexible Configuration: YAML-based configuration for easy setup and reproducibility
• Python Implementation: Modern, well-documented Python codebase with type hints
