APLIKASI SISTEM INFORMASI GEOGRAFIS (SIG) UNTUK PEMETAAN SEDIMENTASI SEBAGAI SALAH SATU UPAYA PELESTARIAN DAS WAMPU BAGIAN TENGAH DI PROVINSI SUMATERA UTARA
Abstract: Wampu Watershed is
defined as the restored watershed carrying capacity according to Regulation of the
Minister of Forestry of the Republic of Indonesia Number P.60 / Menhut-II /
2012. The land use for intensive agriculture is very dominant in Wampu
watershed and increase the damage which is now often felt by the public. For
that reason, that’s done a research for counting the suspended load that
occured in Middle-stream of Wampu Watershed. The research was conducted on May
up to September 2014 in Bahorok, Salapian, Kuala, and Selesai, by using survey
method with taking sample randomly and continued by calculated of suspended load
with United State Beureu Reclamation (USBR) method. Data processing used
ArcView GIS 3.3. The results of this research showed that the highest suspended
sediment discharged in middle-stream of Wampu watershed is 1.501.227,19
grams/second in Tanjung Lenggang, 324.625,29 grams/second in Empus, and
2.572,58 grams/second in Tanjung Keriahen. Therefore it’s necessary to control
by doing an appropriate conservation measures to suppress the larger
possibility of sedimentation.
