Abstract - Landslides are one of the most dangerous
decades, there has been a tremendous increase in the power of technology to mitigate them. As a result, the economic damage caused by natural disasters increases over time. These cuts in human settlements, the new urban environment and the shortening of engineering are consuming some of the natural budget. A risk assessment is required to identify any risk assessment areas that can be used to plan land use. Chandoli region in Maharashtra is divided by arid climate, low population density, natural vegetation, low soil conditions, diverse geomorphology and slope gradient. Any sustainable development strategy in the Chandoli region (western Ghat) faces significant environmental challenges such as landslides, water scarcity, flooding and groundwater pollution. In addition, risky behaviors brought about by rapid development rates can permanently endanger natural resources and culture. Chandoli and its surroundings were chosen as a study to assess the environmental risks of the area and to plan the entire Western Ghats area. The dangers of landslides pose a serious threat to health, property and infrastructure and can be a major barrier to local growth.
natural disasters in hilly areas. The area surrounding the previous landslide in Chandoli District is spread over four districts – Satara, Sangli, Kolhapur and Ratnagiri, Maharashtra districts were chosen as the study area. Landsat8 provides the basis for obtaining basic information about various metrics such as Google Earth, Google Maps and other satellite imagery, as well as Survey of India (SOI) geographic pages, NDVI slope, associated relief, water congestion and geology/lithology. The purpose of this study was to understand the importance of mapping geological bonds and landscape features including streams, slopes and features. Streamline flow is one of the main causes of landslides. Any corrective action should include one or both of the following characteristics. Therefore, the most common landslides are detected using GIS and remote sensing. Analysis images were collected in February 2022 and analysis was completed in May and June.
Key Words: Landslide, GIS, Remote Sensing, Mapping, Survey of India etc.
2. STUDY AREA
1. INTRODUCTION
One of Chandoli's most important water resources is under testing. The tested region is located between latitudes 170°04'00"N and length 170°19'54"D and length 730°40'73"N, and 730°53'09"D length covers an area of one square. mileage 1385.82. Sub-company data will be managed digitally and collateral data will be created on topographic maps. Limited landscape and metaphor estimates for 1977 and 2005 revealed that 120.9 km2 of conifer forests that had existed for 28 years have now disappeared. On the other hand, 51.15 km2 in trees and 64.19 km2 in grassy areas. In addition, forest cover and land use maps of the research area will be included in the data below by using the 'high probability classification method'. This study will help demonstrate that the Park supports a variety of shrub habitats, grasslands, reclaimed land, and conifers. The study will be used to represent the Western Ghats Tropical and Radiation Analysis (Chandoli Forest, Maharashtra) and its environmental impact on the affected area using GIS and Remote Sensing. Since the Sahyadri range is in the middle of the study area and receives heavy rainfall, soil erosion is likely in the region.
Also known as a landslide or mudslide, a landslide is a type of damage that includes various ground motions such as rock falls, deep slope falls, and shallow debris flow. Land degradation is a major problem in almost every part of the world as it causes economic or social damage to private and public property. Natural disasters have demonstrated the devastating power of mass displacement during a devastating earthquake that can cost lives and cause extensive damage to property and infrastructure each year. Remote Sensing (RS) and Geographic Information Systems (GIS) play a key role in effective disaster risk reduction and management and provide a framework for monitoring, evaluation, fault detection and the development of appropriate disaster risk management measures. RS and GIS have become important tools for predicting and measuring natural hazards in geology. GIS can be used to create risk analysis models that can be used to save lives and property, from better knowledge of potential disasters to better knowledge of potential disasters. Although natural disasters have increased dramatically and frequently over the past few
