intro story Lake

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.

Hi

I am a student trying to modelling the hydrodynamic of a laggonal coastal system. This system only have one open boundary, this one is with the ocean (inflow and outflow)
i have all components, phases and amplitudes of the tide in the mouth of the system.
when i check the outputs, the waters levels are in a minimal scale (meter 10^-15) and i don't know why.
What is happening?

Thank you for your advice.

regards

Hi Mario,

Can you check your Bottom Roughness formula ?
