Badlands: A parallel basin and landscape dynamics model

Abstract

Over more than three decades, a number of numerical landscape evolution models (LEMs) have been developed to study the combined effects of climate, sea-level, tectonics and sediments on Earth surface dynamics. Most of them are written in efficient programming languages, but often cannot be used on parallel architectures. Here, I present a LEM which ports a common core of accepted physical principles governing landscape evolution into a distributed memory parallel environment. Badlands (acronym for BAsin anD LANdscape DynamicS) is an open-source, flexible, TIN-based landscape evolution model, built to simulate topography development at various space and time scales.
