They have been studying a way to replenish ground-water during the long drought-period that has affected the agriculture, an important industry in California.
The leading question was: could the tree root-system be negatively affected by artificial water-flooding, during the rainy winter months?
In order to give answer to this question, some Californian researchers have tried to recharge the ground-water by flooding some local orchards during the wintertime.
