SAN DIEGO (CBS 8) - Thursday's storm is actually a huge opportunity for scientists to study beach erosion.
At Cardiff State Beach, Scripps oceanographers are monitoring the shifting sands as the high tides wash them away. Workers pumped in 89,000 cubic yards of sands, and watching it erode will help scientists design better ways to replenish the sand.
"If they hadn't done this so-called beach nourishment, there would be no beach. And in fact these cobbles that you see here, that would be what the beach would be made of," professor Robert Guza said.
There are monitoring devices in the ocean and above the beach to measure the sand elevations and wave action on shore. The sand also helps to create better waves for ideal surfing conditions.
