For most grasses (all but the rhizome varieties like quack, Bermuda, etc.) digging down 4 inches and turning the sod will suffice in eradication, along with putting the nutrients back into the soil from whence they came.
For the rhizome grasses, there will be a recurring battle because of their nature, their roots go deeper and every node will become a plant, (think of strawberries and their runners).
mulching doesn't work on rhizome grasses as well as it does on the fine root varieties, because of that deep root and node construction.
Solarizing the soil also doesn't work so well on the rhizome grasses, again because of their root system.
On the other hand, grasses can be utilized as living mulch and they do keep soil erosion at bay.
