Abstract
The quality of water in a closed water body such as lakes and ponds has been getting worse in recent times. Several measures such as dredging methods have been taken against eutrophication. However, some problems are encountered on the low-water depth lakes. This study conducted fundamental study on cover material to inhibit nutrients elution from bottom sediment using solid waste and geosynthetics. By using this cover material, we can try easily water purification. This study investigated the effect of inhibition of nutrient elution from bottom sediment by cover material by water tank test under the condition similar to actual environment. The results of water tank test indicated that the cover material can inhibit turbidity. This finding is attributable to the fact that cover material of bottom sediment hinders the diffusion of nutrients from bottom sediment to water and prevents further increase of suspended solids.
