Abstract

Management watershed needs to be done unitedly by coordinating, consultation and communication between the parties, and therefore data and information on das' characteristics are indispensable to the management of the das. Particularly the characteristics of morphology and morometry are directly related to the response of rainwater that will become a surface stream. The purpose of research is (I) to examine the characteristics of morometeri das; (ii) assessed the characteristics of morphology das (iii) examined river basins' surface runoff. The study is a quantitative description that utilizes secondary data asa primary source of data and USES the cook's method in determining surface levels by scoring on 4 (the four physical parameters of slope slope, infiltration, land cover, and surface loading. According to research, the smaller classified river basins has a smooth stream of 1.28 km/km clarity, a marble (slope) das antokan is dominated by flat and gentle marbles, an estimated surface of das antokan that a value c or a coefficient value of 0.58 where 58% of the rainwater that falls into the area of antokan will become a surface stream, From this value you can conclude that the flow of the surface or the coefficient of the flow of the surface of the antokan river river could be marked high, the discharge of the top basin of the antokan river by 2, 5, and 10 years worth 503.4 m3/ second, 629.2 m3/ second, and 651.9 m3/ second. The calculation may be stated that ata 2-year anniversary of the duration of the rain (time of concentration) of 6.9 hours with a gradual humidity of 6.4 mm/ 2 millimeters of rain, the maximum discharge obtained on anthocyanin basin was 503.4 m3/ second.

Abstract

Longsor merupakan salah satu jenis bencana yang seringkali terjadi pada DAS Tarusan kabupaten pesisir selatan, Sumatera Barat. Tujuan dari penelitian ini adalah memetakan persebaran zona rawan bencana longsor di DAS Tarusan Pesisir Selatan. Pemetaan zona rawan bencana longsor diklasifikasikan dalam 3 kategori, yaitu zona rawan longsor rendah, rawan longsor sedang dan rawan longsor tinggi. Analisis peta zona rawan longsor dilakukan dengan bantuan alat GIS (Geography Information System). Pemetaan bencana tanah longsor dibuat dengan software ArcGIS dengan metode skoring dan pembobotan, serta tumpang susun (overlay) antar parameter penyusunnya. Acuan parameter yang digunakan dalam analisis adalah Peraturan Menteri Pekerjaan Umum No. 22/PRT/M/2007 tentang Pedoman Penataan Ruang Kawasan Rawan Bencana Longsor. Hasil zonasi rawan bencana longsor pada DAS Tarusan Pesisir Selatan kategori zona rawan longsor tinggi adalah seluas 2564,18 Ha. Kemudian luasan zona rawan longsor sedang adalah 16560,08 Ha. Serta luasan zona rawan longsor rendah adalah 8974,44 Ha.

Abstract

This study aims to determine and map the flood hazard index in Bungus Teluk Kabung District, Padang City. This type of research is quantitative descriptive using secondary data as a data source. The sample in this study is a land unit located in the Bungus Bay Kabung sub-district which was taken by total sampling. The data is analyzed by overlaying the map to determine the level of flood hazard. The results of this study found that the flood hazard zoning in Bungus Teluk Kabung Subdistrict, West Sumatra Province is divided into 2 zones, namely, a medium-prone zone with an area of ​​61.8 Km2 and a high-prone zone with an area of ​​15.87.Km2. The moderate flood hazard zone in the Bungus Teluk Kabung sub-district is spread over 6 sub-districts. Most of the moderate danger zones are located in Teluk Kabung Tengah Village with an area of ​​13.5 km2, Teluk Kabung Selatan 12.03 km2, Teluk Kabung Utara 9.06 km2. Meanwhile, the high flood hazard zone in the Bungus Teluk Kabung sub-district is spread over 6 sub-districts.

Abstract

Abstract The flash flood that occurred in November 2017 in Nagari Guguak Sarai, Sungai Lasi District, Solok Regency caused damage to settlements and agricultural land. The cause of flash flood is landslides in the upstream of the river due to high rainfall. To find out the areas that are potentially dangerous due to the flow of flash flood and the damage affected, it is necessary to map the flash flood hazard index using the mix method. As a result, the total area of ​​the flash flood hazard area reaches 373.347 ha and the area of ​​physical vulnerability reaches 12.33 ha with an estimated loss of more than 200 million rupiah for house damage and an estimated loss of more than 400 million rupiah for damage to public facilities. The flash flood hazard index map is used as a reference to determine areas that have the potential for flash flood overflows and the physical vulnerability map is used as a measurement of physical damage losses due to flash floods in Nagari Guguak Sarai. Keywords— Flash Flood Hazard, Hazard Index, Mix method, physical vulnerability
