dredge material transportation

Simular to most of gray infrastructures, moving dredge material also consumes a large amount

of transportation

INTERACTION OF SEDIMENT

This round of experiments mainly explores It is a convincing process showing how breakwater movement during

PHASE

- 01 1. Placing Dredge Material as Base Layer 2. Wave Pushing Sediment into the Breakwater Field - 02 1. Fine Sediment Filtered By the Geotextiles Fabric Covering and Stablize the Base Layer

SEDIMENT & BREAKWATER

explores the prototype of potential land formation. breakwater and geotextile fabric intervene in sediment during land formation.

PHASE - 04

1. Land Formation Entering to a Stable Status.

2. New Land Could be Used in Agriculture, Wetland, and Recreation Based on Its Features.

1. Phase-03 Has a Great Resilience to Regular Storm Sedges.

2. Considering the Unusually Serious Wave Attack, Its Crush Will Still Ensure the Safty of Coastline.
