Ketika di sebagian alur sungai yang kita modelkan terjadi limpasan keluar alur sungai, maka ada dua cara untuk memodelkannya. Simulasi A memakai fitur 1D: limpasan dimodelkan dengan lateral structure dan kawasan genangan dimodelkan sebagai storage area. Simulasi B memakai fitur 2D: limpasan dan genangan dimodelkan dengan fitur 2D, alur yang lain tetap dimodelkan dengan fitur 1D.<\/p>\r\n\r\n\r\n\r\n<p>Perbedaan hasil dari kedua simulasi ini adalah bahwa Simulasi A memberikan hidrograf muka air dan debit aliran di storage area, tetapi tidak dapat memberikan kecepatan aliran di storage area. Simulasi B memberikan hasil berupa profil aliran (elevasi muka air dan kecepatan aliran) di setiap titik hitung di kawasan genangan. Simulasi B memberikan pergerakan aliran di kawasan genangan.<a href=\"https:\/\/istiarto.staff.ugm.ac.id\/index.php\/2019\/10\/hec-ras-simulasi-1d-2d\/simulasi-1d2d\/\" rel=\"attachment wp-att-4729\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-4729\" src=\"https:\/\/istiarto.staff.ugm.ac.id\/files\/Simulasi-1D2D.png\" alt=\"\" width=\"2304\" height=\"1296\" \/><\/a><\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Melanjutkan tulisan saya mengenai fitur 2D dalam HEC-RAS, saya tunjukkan satu contoh pemakaiannya.
