If you think of it as meaning 'because of', I think the relationships will be clear to you. I wouldn't recommend using 'due to', because strictly speaking, 'due to' has to have a noun antecedent: x is due to y.

Thanks for your reply. I originally had "The study should contain a long-term climate zone map showing areas prone to flooding or drought, hurricanes..." but that doesn't work with the "por dinámica marino-costera part". Grateful for any suggestions about how to word it to fit the dinámica part in. Perhaps "..for areas that are vulnerable due to flooding or drought, hurricanes, coastal-marine dynamics", but I don't like vulnerable due to flooding. Surely they are vulnerable to flooding, not due to flooding. Thanks for any help!
