1. A spreader for sediment capping, comprising:
a hopper having a hollow interior, a first opening, and a second opening, the first opening configured to receive capping material;
a baffle system disposed above the hopper and within the hopper and configured to separate the capping material into a plurality of capping material streams; and
a rotatable drum disposed beneath the hopper, the rotatable drum adapted to receive the capping material streams and disperse the capping material of the capping material streams into a body of water to form a sediment cap on a subaquatic floor of the body of water.
