Dear Authors,

I think that you have addressed the comments by the two referees very well and I expect you to submit a fully revised paper that takes well account of the comments made. In your replies you already showed how you would address the comments in the revised paper, so I have confidence that you will do so appropriately. I shall then ask the two referees if they are satisfied with the way you have handled their comments in your revised version.
Sincerely, Hubert Savenije

Dear authors,

I think you have adequately replied to the referee comments, and I accept the paper. I noticed that in the revisions some minor typo's have appeared (e.g. liner instead of linear). Please go through the text with a fine comb and check the spelling. After final submission, I think the language editor needs to go through the document to make the text better readable.

Sincerely,
Hubert Savenije
