How does Marguerite Duras use imagery in The Lover?

Imagery:

"Fifteen and a half. The body is thin, undersized almost, childish breasts still, red and pale-pink make-up. And then the clothes, the clothes that might make people laugh, but don't. I can see it's all there. All there, but nothing yet done. I can see it in the eyes, all there already in the eyes.

"All around the ferry is the river, it's brimful, its moving waters sweep through, never mixing with, the stagnant waters of the rice fields. The river has picked up all it's met with since Tonle Sap and the Cambodian forest. It carries everything along, straw huts, forests, burned-out fires, dead birds, dead dogs, drowned tigers and buffalos, drowned men, bait, islands of water hyacinths all stuck together. Everything flows toward the Pacific, no time for anything to sink, all is swept along by the deep and headlong storm."
