Telah dilakukan penelitian tentang jenis material sedimen dasar sungai di Desa Sungai Duri Kecamatan Bengkayang Kabupaten Bengkayang. Penelitian ini bertujuan untuk mengetahui jenis material sedimen dasar, sebaran sedimen, tekstur tanah dan statistik sedimen. Pengambilan sampel sedimen dilakukan di tiga kelokan sungai. Kemudian dilakukan uji laboratorium untuk mengetahui jenis butir, sebaran sedimen, tekstur tanah dan statistik sedimen. Hasil penelitian berdasarkan klasifikasi USDA (United States Departement of Agriculture), menunjukkan bahwa terdapat tiga jenis material sedimen yaitu pasir, lanau dan lempung. Persentase rata-rata jenis butir sedimen dasar sungai di Desa Sungai Duri adalah pasir 9,5%, lanau 50% dan lempung sekitar 40,5% yang tersebar di tiap penampang. Kelas tekstur tanah untuk sedimen dasar sungai di Desa Sungai Duri adalah jenis liat berdebu, sedangkan untuk nilai statistik sedimen diperoleh hasil sorting sedimen adalah porly sorted, kemencengan sedimen menceng kasar dan kortosis sedimen termasuk dalam kategori tumpul.
