卡普阿斯河
The first four of the above districts lie on the south bank of the Kapuas River (listed from west to east), while the last two districts lie on the north bank (the East and North districts are separated by the Landak River, which joins with the Kapuas Kecil River at this point to create the Kapuas Besar River). The built-up or urbanized area continues southeastwards along the south bank of the Kapuas River into the town of Sungai Raya, a "kecamatan" in the Regency of the same name.
