### Final Analysis Result: Coastline Modelling in Seashore Jogjakarta's Airport

1. 1. Analysis Result | KL6200 Ocean Environment Modelling Faisal D Purnawarman | 25513009 Coastline Modelling in Seashore Jogjakarta’s Airport
2. 2. Background  The old airport is full capacity, and can’t be expand  Chosen location of new airport is in seashore with:  Reclamation area  Between two big rivers  Waste water outlet in the river
3. 3. Location  Address : Kecamatan Temon, Kulon Progo sub-district, Jogjakarta  Coordinate : -7.908761, 110.061031  Characteristic : 4 kilometers long and 2 kilometers wide along seashore  Location between 2 rivers, Congot River and Serang River
4. 4. Objectives To show coastal line changes in effect of establishment of new airport (with reclamation area and seawall)
5. 5. Methodology Using GENESIS to perform longshore sediment transport
6. 6. Work Phase  Coastline modelling with AutoCAD  Import coastline in x and y coordinate format  Modelling coastline with metocean data in Genesis  Plot result of new coastline  Modelling coastline with seawall  Run analysis in Genesis with protection structure  Plot result of new coastline with protection structure  Compare the result and make conclusion
7. 7. Modelling Coastline  X and Y coordinate *attached  Wave parameter (height and period) *attached  Beach parameter:  Grain size = 1 mm  Beach gradient = 1:5 (vertical vs horizontal)  Water elevation = 2 m  1st coefficient = 0.1  2nd coefficient = 0.05  Land to beach direction = 1800 (South direction)  Time interval = 10 years  Time step = 24 hours
8. 8. Analysis Phase 1 Modelling sedimen transport without seawall 2 Modelling sedimen transport with seawall
9. 9. Analysis Result  Coastline without seawall
10. 10. Analysis Result  New coastline without seawall
11. 11. Analysis Result  Coastline coordinate comparison without seawall
12. 12. Analysis Result  Coastline with seawall
13. 13. Analysis Result  New coastline with seawall
14. 14. Analysis Result  Coastline coordinate comparison with seawall
15. 15. Conclusion The reclamation area should be protected by seawall to save the reclamation area from abration and longshore
