First of all,the dam is too close to the village and if the dam gives way,the whole village will be destroyed.The wall should not be straight.
2. Why the crack appeared at the location and not anywhere above?
the water currents are stronger at thev bottom.
3. Offer a better design with explanations
make the wall like a v shape...it will be able to contain more water and the bottom will be able to take the preasure.
You should have use the resectioning, bank protection and planting vegetation methods that we've learnt in geography. But can see you've used v-shape for the wall of the dam. :)
