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.

 
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.

Lake and Reservoir Sediment Transport Modelling

Hello,

I just want to ask you, if the Open Delft 3d can simulate the sediment transport in lakes or reservoirs? I also want to know, if there is a restriction about the boundary conditions that could limit the model in this kind of applications.

I was looking at the literature about this topic without success. So, if you can help me with some references about this, I will appreciate it.

Thanks for you time and answer.

Best regards.

Hi Gabriel,

You could try to use Delft3D (sigma-layer model) to simulate sediment transport and morphology for lake and reservoirs if the stratifications are not too strong. The stratifications I mean is the thermocline (temperature) or stratification due to sediment concentration in the water volume.

If that is the case, you might need the anti-creep option in the model, which is published in Van Kester et al 2002. (i.e., 3D simulation of the hydrodynamics in lakes with Delft3D-FLOW). Otherwise you have to turn to z-layer model.

Hope this could help you a bit,

HI Gabriel
I want to model 3d dam reservoir sedimentation via delft3d too.
when the water level in reservoir drawn down upstream river water level, delft3d errors and couldn't run.
Do you have this problem so?
Do you know what is wrong?
thank you, if you can help me,
