                    Jenis-jenis PWH Lewat Sungai Lewat Udara Lewat Darat

                    Lewat Sungai

                    Karakteristik Murah Mudah Tergantung alam

                    Lewat Udara

Lewat Udara                    

Karakteristik Mahal Hanya cocok untuk kayu mahal                     Karakteristik Mahal Hanya cocok untuk kayu mahal Cocok untuk lokasi remote dan sulit Cocok untuk kayu-kayu besar dan berat JARANG DIGUNAKAN

Lewat Darat Cukup mahal                     Cukup mahal Kemungkinan berdampak negatif terhadap lingkungan sangat besar Bisa diintegrasikan untuk kegiatan lain dan pengembangan wilayah PALING BANYAK DIGUNAKAN

                    PWH lewat darat Konsekuensi dari perencanaan dan pembuatan jalan yang tidak benar: Biaya tinggi Sedimentasi yang berlebihan Erosi tanah yang berlebihan Berpotensi untuk memicu tanah longsor
