intro story Lake


Lakes and reservoirs are important resources for communities around the globe. They provide food, drinking and irrigation water and can also offer spots for recreation. Under certain conditions lakes can also represent a threat for local communities, such as flooding or limnic eruptions. The ecological state of shallow lakes may be hampered by suspended sediments due to wind driven currents and waves. In deep lakes, stratification can cause undesirable anoxic conditions in the deeper areas. Understanding these systems is crucial to enable a sound management of these water bodies.

Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of lakes.

Wave flow coupling - delft3d - repeat looping through first two time steps

Hi All,I am running an online coupling of wave and flow. I am using .bcw file to apply uniform wave boundary TS at my nested grid. (I got the TS from the coarse grid). My model is running however it keeps doing an endless loop between two first timesteps. I am puzzled and I can't figure out what I am doing wrong. Attached my bcw , mdw, and mdf files. Any help would be much appreciated.Regards,Nora
