aliran airbumi sebelumnya. Pada saat kurva hidrograf menurun, debit airbumi menurun dibandingkan pada puncak hujan.

Penelitian ini terlaksana dengan melalukan beberapa pendekatan melalui metodologi yang telah banyak dilakukan di luar negeri oleh para peneliti hidrologi
proses. Untuk mendapatkan informasi yang lebih komprehensif tentang perilaku hidrokimia di dalam DAS, perlu dikembangkan penelitian sejenis pada masa yang
akan datang, didukung oleh peralatan yang lebih memadai. Persamaan – persamaan
dan model matematik serta penggunaan perangkat Sistem Informasi Geografis juga perlu dikembangkan dalam menyusun dinamika aliran bawah permukaan . Karena
teknik pemisahan aliran permukaan ini dapat mengkuantifikasi sumber source limpasan yang sangat penting dalam mendesain stuktur hidraulik, evaluasi model
hujan-aliran permukaan, mempelajari proses pengendalian banjir, serta pendugaan dan
pengurangan kontaminasi air.
