We planted 35 Viburnum plants around our pool in Cyprus. This was done in March. Now in August, a lot of the leaves have turned brown. Some of the plants look very healthy and some are just dying by the day. Could there be any reason for this? They are watered every other day.

Even though they are getting water pretty regularly, it may not be enough for them to establish and they may be going into transplant shock.
Plants were not meant to move, but we humans like to move them. Some plants, like annuals and small perennials, can establish quickly and you will only see signs of transplant shock in the first few weeks or so. But plants like trees and shrubs establish more slowly and you can see signs of transplant shock for up to 6 months after they are planted.
Lots and lots of water is the key to plants establishing well, so trees and shrubs need more water that first year than they will need later on.
Basically, I would recommend increasing water to the failing plants. Maybe providing a little shade for them too, if you can. This article will have more information on dealing with transplant shock:
