coupling river junction with sediment transport

Dear fellow modellers,

I try to model a river junction with BASMENT v2.8 in 1D. I have created three domains, two domains for the main river and a third domain for the smaller river which flows into the main river.

As for the coupling type, I have used "junction" with two upstream subdomains and one downstream subdomain.

		COUPLING {
			type                 = junction
			upstream_subdomain1  = rotten_upstream
			upstream_subdomain2  = saltina_kanal
			downstream_subdomain = rotten_downstream
			two_way_coupling     = yes
			HYDRAULICS {
				upstream_interface1  = rotten_outflow_upstream
				upstream_interface2  = outflow_saltina
				downstream_interface = rotten_inflow_downstream
			}
			BEDLOAD {
				upstream_interface1  = rotten_outflow_upstreamsed
				upstream_interface2  = outflow_saltinased
				downstream_interface = rotten_inflow_downstreamsed
			} 

Running the model without sediment transport seems to be working. If I add the morphology blocks and create a bedload coupling, BASEMENT crashes without any error message.

Have you experienced similar issues? If so, have you found a solution?

Cheers

Mathias
