Results file:///perm/pad/climsfc/49r1_shallow_lakes/plots/eval_mon.html indicate neutral impact from changing the minimum lake depth.

Lake mean depth correction/upgrade details the recently updated lake depth (i.e. new bathymetry for Caspian Sea, Azov Sea, Titicaca Lake, how we recognize lakes to map mean depth.

Experience with Time-varying lakes can help handle inundation and water recess. Time-varying lakes: offline model changes (+ experiments 1992-2019) are a useful set of experiments.

revised permeability limiting freezing shutdown to 20% of soil

Results file:///perm/pad/climsfc/49r1_shallow_lakes/plots/eval_mon.html indicate that 50% permeability in frozen soil condition can increase the overall soil water storage.

A new soil discretisation (control experiment iv3r) and new climate fields version (climate.v023) will be tested in parallel and the CAMA-Coupling of lakes and inundation require alignment with the Hydro branches. Here 2 work in progress experiment (not yet completing):

A set of case studies is identified and the plan is to compare with the operational runs and the Atos DestinE Extremes DT run. The control TEST: Run ecLand/CaMa-Flood with SDFOR instead of SDOR can provide the starting point from both 9 and 4km coupled testing. Offline DestinE new experiments are also providing a useful batch.
