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.

Modelling storm surge

Hi Everybody,
I am pretty new in Delft3D . I am trying to model a nested hydrodynamic and sediment transport model coupled with wave. I would like my model to include storm surge. I have a couple of questions:
1. Other than space time varying wind data, do I need to add pressure as well in order to capture storm surge accurately?2. I have a large computational domain and I could just find some atmospheric pressure data which will be located in downstream of my model (coarse grid) however I don't have any pressure data in the estuary where I have a finer grid and local effect. Is there any resource I can find the atmospheric pressures?
3. If I want to use space varying wind on the computational domain, how can I input multiple meteo stations into to the model. Can I use multiple .wnd files or I need to interpolate all of them into one file?
Thank you in advance!
