This study presents the use of geographical information system (GIS) datasets and methods to investigate landslide susceptibility in rugged mountainous terrain Shigar Shyok Basins northern areas Pakistan. Study area is situated Karakorum region where catastrophic landslides occur frequently pose a serious threat local living conditions. Landslide index maps were prepared by combining four main indicators groups: (1) human induced parameters, which contain Landsat 8 imagery distance from...
Abstract Spatial–temporal rainfall assessments are integral to climate/hydrological modeling, agricultural studies, and water resource planning management. Herein, we evaluate spatial–temporal trends patterns in Pakistan for 1961–2020 using nationwide data from 82 stations. To assess optimal spatial distribution characterization, twenty-seven interpolation techniques geo-statistical deterministic categories were systematically compared, revealing that the empirical Bayesian kriging...
Coastal erosion endangers millions living near-shore and puts coastal infrastructure at risk, particularly in low-lying deltaic coasts of developing nations. This study focuses on morphological changes along the ~320-km-long Sindh coastline Pakistan over past three decades. In this study, Landsat images from 1989 to 2018 an interval 10 years are used analyze state erosion. For purpose, well-known statistical approaches such as end point rate (EPR), least median squares (LMS), linear...
This study employed remote sensing (optical and synthetic aperture radar) data analysis techniques to quantify vertical ground displacements assess their contribution coastline erosion. To provide evidence from Pakistan, we selected the coast of Karachi—a mega-city located along dynamic Indus River Delta—which has been experiencing severe coastal erosion during last few decades. Observations C-band Envisat/ASAR Sentinel-1A sensors over 2004–2010 2014–2016 periods, respectively, enabled us in...
Karachi is located on southernmost border of Pakistan along the Arabian Sea coast. Concerned institutions fear occurrence subsidence in city, further contributing to relative sea level rise. No direct measurement has been made so far about rate and its contribution city's submergence risk. Our study presents first preliminary results vertical ground deformation over this area using an advanced Temporarily Coherent Point InSAR technique Envisat/Asar Sentinel-l A data. These datasets allowed...
Barrier islands (BIs) are the first line of defense against sea/wave actions in coastal areas, and assessing their stability is crucial context effective planning. Therefore, this study evaluates spatial–temporal shoreline changes BIs Pakistan over past three decades (1989–2018). Satellite data from Landsat missions used to delineate shorelines 19 Pakistan. After delineating satellite observations, two well-known statistical methods (i.e., end point rate (EPR) linear regression (LRR))...
