Compound Topographic Index

Soil landscapes and their component facets (or sub-units) are fundamental information for land capability assessment and land use planning. The aim of the study was to delineate soil landscape facets from readily available digital elevation models (DEM) to assist soil constraint assessment for urban and regional planning in the coastal areas of New South Wales (NSW), Australia. The Compound Topographic Index (CTI) surfaces were computed from 25 m DEM using a D-infinity algorithm. The cumulative frequency distribution of CTI values within each soil landscape was examined to identify the values corresponding to the area specified for each unmapped facet within the soil landscape map unit. Then these threshold values and CTI surfaces were used to generate soil landscape facet maps for the entire coastal areas of NSW. Specific programs were developed for the above processes in a geographic information system so that they are automated, fast, and repeatable. The modelled facets were assessed by field validation and the overall accuracy reached 93%. The methodology developed in this study has been proven to be efficient in delineating soil landscape facets, and allowing for the identification of land constraints at levels of unprecedented detail for the coast of NSW.

Abstrak: Sub DAS Amprong secara administrasi masuk pada wilayah Kabupaten Malang dan Kota Malang. Meliputi lima Kecamatan yakni: Kedungkandang, Poncokusumo, Tumpang, Pakis dan Jabung. Risiko bencana longsor tergolong tinggi pada kawasan ini. Maka dari itu, penelitian ini bertujuan untuk melakukan pengurangan risiko bencana longsor mengunakan pendeketaan GIS (Geographic Information System). Menggunakan GIS distribusi tingkat risiko akan dapat diketahui dengan baik, sehingga mampu memberikan solusi yang lebih akurat. Penelitian ini meliputi empat tahapan: 1) pemetaan bahaya longsor, 2) pemetaan kerentanan bencana, 3) pemetaan kapasitas bencana, 4) pemetaan risiko bencana. Hasilnya diketahui bahwa kecamatan Jabung dan Poncokusumo merupakan wialayah dengan tingkat risiko longsor paling tinggi. Upaya yang dapat dilakukan untuk mengurangi tingkat risiko dapat dilakukan melalui mitigasi bencana secara struktural dan nonstruktural. Wilayah dengan risiko tinggi bukan merupakan kawasan pemukiman, namun memiliki aktivitas utama berupa pertanian. Oleh karena itu perlu adanya manajemen risiko bencana longsor dalam usaha longsor seperti: dengan cara: 1) pengaturan sistem irigasi dengan baik, 2) penerapan sistem terasering, dan 3) pemasangan bronjong pada kaki lereng. Abstract: Amprong watershed is administratively included in Malang Regency and Malang City. Includes five districts namely: Kedungkandang, Poncokusumo, Tumpang, Pakis and Jabung. The risk of landslides is classified high in this region. Therefore, this research aims to reduce the risk of landslides using GIS (Geographic Information System). Using GIS the distribution of risk levels will be well known, so as to provide a more accurate solution. This research includes four stages: 1) mapping of landslide hazards, 2) mapping of disaster vulnerability, 3) mapping of disaster capacity, 4) mapping of disaster risk. The results are known that the Jabung and Poncokusumo sub-districts are areas with the highest risk of landslides. Efforts that can be made to reduce the level of risk can be done through structural and nonstructural disaster mitigation. High risk areas are not residential areas, but have major activities in the form of agriculture. Therefore, it is necessary to have landslide risk management, such as: by: 1) regulating the irrigation system properly, 2) applying the terracing system, and 3) installing gabions at the foot of the slope.

<p class="TableParagraph"><em>In 2006, a tsunami disaster occurred on the coast of Pangandaran Regency which claimed up to 664 fatalities. A large number of people died due to lack of information in knowing areas that are prone to tsunami disasters. Therefore, a geographic information system for the tsunami disaster is needed to facilitate the Pangandaran community to find out areas that are prone to tsunami disasters. In making a geographic information system web tsunami disaster using GeoServer, PostgreSQL and LeafletJS. Making a geographic information system web is done in several ways, namely, entering shapefile data into a database and then displaying it on a map server.

The Impact

Flood disasters cause negative impacts, such as damage to facilities to the onset of fatalities. Reducing the risk of flooding needs to be done to reduce the impact caused by this disaster. Lamongan Regency is one of the regencies in East Java affected by floods every year in most of its areas. This study aims to reduce the risk caused by flooding by using GIS (Geographic Information System). Mitigation is done by determining areas with a high potential risk of being affected by flooding. The study used spatial analysis functions in ArcGIS. Supporting variables used rainfall, land cover, slope, soil texture, and watershed area, and it becomes important in determining flood-prone areas. From the results, the largest soil classification is the Kpl soil type. Litosol Gray Grumosol, The wide distribution of rainfall from 1500-1750 mm has the widest distribution is 66,67 ha. The slope of 0-8% has the widest distribution of 92,257 ha, making Lamongan a very vulnerable high flood area. Laren District is the District with the greatest flood potential, and Irrigated Field is the dominant land cover type affected by the flood. With the flood disaster map generated from this research, local governments can seek prevention in areas with high flood potential. They can carry out socialization based on disaster mitigation, especially for districts with potential flooding.

The Government

The most desired disaster prevention in Taiwan has to be typhoon; therefore there is a saying good weather, good life. The government does everything to prevent nature disaster, preparedness, response and recovery, especially on typhoon flooding survey. In order to conduct instant contingency handling disaster reaction in biggest disaster conditions, the government hopes to control the disaster immediately, and calculate the disaster loss. The main purpose of this study is to build a flood automation system. Apply auto-recording water level monitoring system (internal or external water) from water stations to collect stage data, and integrate Geographic Information System by the terrain grid computing, then obtain the instant scope of inundation and flood depth. Together with the instant rainfall and forecast to achieve the effectiveness of the flood watch or warning, then we should possibly control the instant information for the anticipation of the flood disaster. Taking it further with the Flood Security Plan, we have the best reference for decision-making use in the Emergency Response Center. The study area is located in Yilan County, the most sensitive flooded region, to set up immediate foregoing typhoon instant information system or so-called flood automation system, and then by several times of investigations and post-disaster flood scar volume measured we completely record ground hydrological information, and calibrate it with water level gauges built by Taiwan National Typhoon and Flood Research Center and AWRSIP weather telemetry information platform of synthetic aperture radar images on the flooded scope and depth. The concept of flood automation system is based on the fact that the occurrence and distribution of flood is not merely a product of chance, but the result of a combination of climatic, hydrologic, geologic, topographic and soil-forming factors that together form an integrated dynamic system, thus, through a combination of real-time rainfall forecast, flood recording, automation requirement, Geographic Information System, flood warning, instant data transmission and the internet, be setting up an ideal typhoon instant information system, which can become high accurate and be suitable for easy use of flooded areas, in order to achieve sustainable development in those areas.
