Terraced Landscapes as NBSs for Geo-Hydrological Hazard Mitigation: Towards a Methodology for Debris and Soil Volume Estimations through a LiDAR Survey

Terraced landscapes are widely used in many mountainous regions around the world as a result of the need to practice subsistence agriculture. A series of sub-horizontal and sub-vertical areas have often used stone walls to achieve their implementation, which has resulted in the artificial immobilization of rubble and soil along the slopes, which are often interrupted by a sequence of sub-horizontal and sub-vertical areas. Higher temperatures and higher levels of rainfall are predicted to accelerate the degradation process even further, causing terraces to function as a source of dust or hyperconcentrated flow. The study, conducted in the hope of advancing the current hazard assessment methods by combining numerical modeling with processing of high-resolution LiDAR data. The catchment scale approach, which was applied to eight smaller catchments, allows estimation of the total volume of soil and debris embedded along the slopes.

Analysis of Lightning Hazard Scenario: A Study on Pabna District, Bangladesh

Bangladesh is a nation beset by natural disasters, the bulk of which are caused by hydro-meteorological causes. Climate change has a direct effect on the severity and frequency of these events. Bangladesh is one of Bangladesh's most lightning-prone countries with a maximum flash intensity density of 72 flashes per square kilometre, accounting for more than half of all deaths. The study's aim is to investigate lightning strike causes and causes, as well as public knowledge, recall, and taking prompt steps in the case of a lightning attack. Public knowledge, analysis, and response to the lightning threat in Bangladesh's Pabna district are insufficient to minimize lightning damage and must be enhanced. This data can be used to raise public awareness of the risks of lightning and how to deal with it safely.
