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.

Question For Delft3D-Flow

Youngling Posts: 2 Join Date: 1/7/15 Recent Posts
Hello, Guys~

My name is Wonhyun Lee, now I am interested in Cyclone model, but I have a big question for that.

In particular, for the evaporation and precipitation rate.

well, normally, Delft3D-Flow provides the XXX.eva (additional parameter : Fileva ;#XXX.eva#) files to apply it.


I would like to apply the spatial-temporal varying evaporation and precipitation rates into the model.
For example, if the cyclone is moving and landfalling to some area,
normally lots of rainfalls is accompanied with a hurricane.

So, could you please let me know, 'spatial-temporal varying evaporation & precipitation rates are available for Flow model?
any tips for input files (evaporation and precipitation rates)
or is there any option that evaporation & precipitation rates are included with a hurricane?

Have a great day.
