Cryoucalving-2019 is an experimental code designed to simulate the collapse process of glacier front ends by adding a minimum frontal ablation model to the OGGM framework. This code achieves its goals through the following functions: • Simulate the disintegration process at the front end of a glacier • Estimate the contribution of glacier disintegration to the total material balance • Study the response of glacier disintegration rate to climate change • Analyze the sensitivity parameters of glacier collapse • Integrate the disintegration process in the OGGM framework
