Dear Emily,
i just experience the same case last week as it broke down after 10 min with the same error:
elevation to low on flooded boundary or "Blow up

a friend told me maybe was manning value cannot put constant, have to link to manning value in map.

Instead ,the problem might cause by at wet boundary. So I make sure my boundaries  which i need to insert dfs1 to be below initial water level. M21 will run....good luck

Dear all,
i found the error message in Mike21 :Elevation to low at flodded boundary
i have tried to run in 1sec timestep, setting 2 boundaries with dfs1,
1) deepen the boundary => Elevation to low at flodded boundary
2) higher than land cell at boundary => water level keep increase in reservoir, wrong simulation
3) distribute to 4 source point => Elevation to low at flodded boundary
4) not setting boundary (as constant = 0 meter) => Elevation to low at flodded boundary

Ohh...gosh??? what can be the likely cause?

Dear all,

can anyone tell me some of my queries:
1) dam breach level: does this refer to the breach start from dam crest level until the dam toe level (overtopping failure)?
2) dam breach width: if the breach section is trapezoidal, does the width refer the top or bottom width of breach section?
