Reduced river sediment load increases which effect via karst?

💡 Explanation

Decreased sediment causes enhanced dissolution in caves as abrasion decreases, because there is less physical protection on limestone surfaces via abrasion; therefore, chemical weathering increases, rather than reduced cave collapse, which would require physical erosion.
