Chemical parameters coastal modelling

Hello Yoda,

There is a list of properties here: OpenFlows FLOOD List of Property and Variable Names. 

Information on coastal modeling is found here:  How to setup a coastal flooding simulation in OpenFlows FLOOD .

If you need further information, please let us know.

Hello,

I've read the list of properties and I just found Ammonia and pH which exactly suit with my objectives. Also Oil property, it is could be Oil & Grease? and CBODD it is refers to COD? Then what about the Fe and Mn properties, could it still possible to model it?

Regarding my coastal modelling I've construct hydrodynamic model by OpenFlows FLOOD Mohid Water (was:  Hydrodynamic simulation error (65) )  and now the simulation seems OK, then I've plan to use Eulerian method for the discharge. Is there any recommendation, please let me know.

Thanks and regards

Hello,

Regarding simulating Fe, Mn, Ammonia, Oil & Grease, pH, and COD here are some comments:

- Fe, Mn and grease can be simulated only as "conservative" constituents, meaning the model only simulates transport but not any biogeochemical reactions. 

- Ammonia can be modelled the same as the other above, but to model it's part in the nitrogen cycle in the water it has be as part of the WaterQuality module. This requires the full implementation of nitrogen cycle in the WaterQuality module and you'll need to simulate algae, zooplankton, oxygen, nitrate, nitrite, dissolved and particulate refractory and non-refractory nitrogen. 

- COD is not possible to simulate, only BOD. This can be done using an Eulerian (discharges module) approach or a Lagrangian approach. 

- pH can be simulated to some extent, by MOHID Water, but it's not supported by OpenFlows FLOOD. 

- Oil is simulated using the Lagrangian module and it's more directed to hydrocarbons like crude, diesel, fuel, etc. 

To be able to provide to you with more information I'll need to understand what type of problem you're trying to solve. What type of discharge (urban wastewater, industrial)? Is it via surface discharge or submarine outfall? 

Kind regards,
Luis

Hello,

Thanks for the explanation, so basically any properties could be simulates only for the transport distribution as conservative properties without require other feature?

About oil properties, I mean it's more like a glycerides, is it still possible? 

My problem is I want to simulates surface discharge from stockpile runoff and office wastewater in one outfall 

Please let me know about any recommendation about this cases

Thanks and regards

Hello,

Any property can be simulated as a conservative constituent For some we may activate options to compute "sinks" and "sources". 

For glycerides, the engine does not have any "sinks" and "sources" module, only transport due to advection and diffusion. I don't think the oil module can be adapted for this type of pollutant. 

From what I understand the only property on your list that FLOOD can fully compute is BOD. How big is the discharge flow? From what you mention the best approach might be to compute the discharge using the Lagrangian module. 

To do this you can first run the hydrodynamic simulation and validate it. 

Then follow the instructions on this article: Simulating BOD in OpenFlows FLOOD. 

Kind regards,

Luis
