Flood extent forecasting

Flood extent forecasting is the task of predicting a binary 2D flood extent map (water vs no water), given input drivers and forcings. The focus is specifically on the impact and extent modeling, such that e.g. atmosphere state (such as precipitation) may be assumed as inputs, to disentangle the impact modeling from upstream challenges such as weather forecasting. This is complementary to time series forecasting of river streamflow and runoff, as well as post-hoc mapping of floods. For related work, data & benchmarks, see https://arxiv.org/abs/2409.18591.
