Hi,

I'm having some problems with horizontal streaking in my model output. I am using a 5m resolution DEM and a sea level rise of 1.8m. I find there is no to minimal streaking if I use a lower sea level rise (eg A1F1) or a coarse (e.g. 30m) DEM (but I would like to use the finer resolution DEM and higher sea level rise).
I have tried checking/unchecking overwash, but this didn't help (nor did changing all the overwash parameters to 0).
I've also tried checking/unchecking soil saturation, which also didn't help (although checking it made it even streakier).
I've experimented with altering many of the other parameters (e.g. use elevation pre-processor, putting 'false' next to accretion parameters) but this also didn't help.
I couldn't find any artifacts in the elevation dataset on a visual inspection.
Is there a solution to this using my current data resolution and sea level rise? Or should I scale up the elevation data?

Thankyou,
Rebecca.
