Defining Particulate Metal in function of suspended solids

Postby » Tue Jul 02, 2013 09:00

Dear all,

I work with a mohid river network fed with SWAT inputs (using the SWAT-MOHID coupling).

I wish to input three properties in my river: Suspended solids (using "cohesive sediment" property), dissolved metals, particulate metals.

My question is: Can I define the "particulate metal" as a concentration of suspended solids? In other words, can I define the input of particulate metals in mg/g (mg of part. metal per g of suspended solids)?

Thank you

Hello Cyrill,

All properties in the river that are travelling in the water column have units of mass/volume or concentration (even if they are particulated or dissolved).
What distinguish particulate from dissolved is that particulate has a fall velocity and can deposit in the bottom.

So if you have metal in units of mass metal/mass cohesive sediment you have to make the math in the discharge to transform it to mg metal / L discharge.
