2D Sediment Transport Modelling with Gates in HEC-RAS

I want to develop sediment transport 2D model and flow 2D model on floodplain river. What is te best software package for it? How can I get them? What is process of acquiring CCHE2D. FLOW 2D, SRH 2D, Delft 3D, Ansys or CFD kind software with full version?

Dear All,

I have an issue regarding a sediment transportation simulation. I have computed the sediment transport rate based on a 20 years wave climate, and simulated the sediment drift for the total time span and either by monthly filtering of the data, the monthly sediment transport is also computed. However there is a problem that the summation of monthly sediment transport is much more than what I have calculated for the total time span. Is it possible this happening? Is there any reason behind this?

I appreciate it if you could share your Idea with me.

I'm finding a 3D hydrodynamic model that considers the processes of water & sediment quality and sediment transport at the same time.

Delft3d seems to be a good one, as Delft3d-WAQ couples the deposition of organic matters and sediment transport and wave can be computed as well.

SCHISM seems to be another good model system as it contains all needed module, however, I'm not sure if it can work as Delft3d-WAQ.

Therefore, I want to ask:

1. Is SCHISM okay for the above requirements (considering the processes of water & sediment and sediment transport at the same time)?

2. Is there any other models that meet these requirements?

Your help will be the most grateful.

The data I have to incorporate in the stratigraphy section will include lithologies such as metamorphic rock (basement), granite (intrusive), shales of variable thickness and colors, Ages of each lithology, andesite and granite (extrusive), and unconformities.

How does reservoir sedimentation affect downstream environments and how does the sediment size and shape change downstream?

I have the data for oleic acid percentage in oil. Can I calculate the triolein percentage based on this value
