Building a Dirt Barrier in Front of the Church in Drainsim? Can we keep it dry?

In one of my previous video's I told that the Church in DrainSim was actually sitting in what appears to be a 'bowl'. Now most of the time we used water-barriers or dirt barriers near the canal breach in order to keep the water there. In this video however I am going to build up a Dirt Wall directly in front of the Church. The initial influx is not the thing to worry about, it's actually all the extra water that follows that will cause the challenge. Can we keep the Church dry?
