Morfologi delta yang diklasifikasikan menjadi 3 ujung ekstrim: Delta Dominasi Sungai, Delta Dipengaruhi Gelombang, dan Delta Dipengaruhi Pasang-surut, menunjukkan perbandingan kekuatan relatif antara besarnya volume suplai sedimen darat melalui sungai yang diendapkan ke laut atau danau dengan kekuatan pengaruh gelombang dan / atau pasang-surut laut atau danau. Berdasarkan ketiga klasifikasi utama delta di atas, pemetaan karakter delta modern di Asia Tenggara bagian selatan –yang meliputi wilayah Malaysia, Brunei, Indonesia, dan Timor Leste- dan Papua Nugini dilakukan dengan metoda pengindraan jauh pada skala pengamatan 1 : 100.000.
During year 2005 – 2009, observations on modern sediment of Mahakam Delta in the southern and the northern lobes were conducted using grab samples of the river bed in conjuction with echo sounding, shallow core sampling, and salinity measurements. The delta environment observed were head of passes, upper delta plain, lower delta plain, and delta front. The purpose was to try making as detailed analogues as possible to the Miocene/Pliocene deltas being explored and exploited in the area.
