This Proterozoic (1.72–1.87 Ga) terrain had have experienced intensive weathering processes over the long period under different climatic conditions. A total number of 965 Rebound (R) value were collected from eight geomorphic features located in the USKI. In the present study, an attempt has been made to synthesize the history and variation in intensity of weathering using Schmidt hammer (SH). The degree of weathering is calculated using micro-weathering index, which is formulated on Schmidt hammer R-values, collected from deeply weathered (DW) and relatively less weathered (RLW) rock surfaces. The results of the study revealed the different response of diverse types of rock to the geomorphic processes. The weathering grade of each identified geomorphic features has been computed and the results revealed that seven features belong to moderately weathered (grade III) out of eight identified features. The present study is a unique attempt considering multi-cyclic evolution of CGGC to understand the degree of weathering of these studied features, belonging from USKI. This study helps to understand the weathering grade of studied features in quantitative way.","PeriodicalId":54618,"journal":{"name":"Physical Geography","volume":"44 1","pages":"362 - 379"},"PeriodicalIF":1.6,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48427214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study attempts to evaluate the role of meteorological, topographical, and geological parameters to understand the regional distribution and plausible genesis of supraglacial debris in the H-K area. Glacier-wise Fractional Debris Cover (FDC) for ~5000 glaciers have been estimated using LANDSAT-7 data (1999–2001) based on the Normalized Difference Snow Index. The aforementioned parameters, including FDC, are compiled into a comprehensive database and analysed. Moreover, “2-meter air temperature” from ERA-5 climatological data is used to estimate the number of Freeze–Thaw Cycles. Overall meteorological and topographical parameters show a significant correlation with the distribution of FDC across the H-K region, more prominently for glaciers having low FDC (<0.2). FDC distribution shows a strong dependency on glacier hypsometry with the highest FDC for “Very Bottom Heavy” glaciers and the lowest for “Very Top Heavy” glaciers. The glaciers with Limestone bearing lithology have maximum FDC and are sparsely distributed, but the glaciers with quartzite bearing lithology are widely distributed across the region and have lower FDC.","PeriodicalId":54618,"journal":{"name":"Physical Geography","volume":"44 1","pages":"620 - 642"},"PeriodicalIF":1.6,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48703991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pakistan’s irrigation water supply primarily depends on the Indus River. Identifying the spatio-temporal dynamics, response patterns of snow cover area (SCA) and surface water bodies (SWB) to climate change are vital for understanding the changes in the hydrological process of the Indus basin. Therefore, the SWB area was investigated using surface reflectance data (MOD09A1) from the Moderate Resolution Imaging Spectroradiometer (MODIS) and SCA changes were examined using MODIS snow cover data (MOD10A2) from 2009 to 2018 in Gilgit Baltistan with respect to climatic variables. According to results the SWB area in Gilgit Baltistan, for annual, summer and winter, changes at the rate of −0.00057% yr−1 (p > 0.05), −0.00042% yr−1 (p > 0.05) and 0.00037% yr−1 (p > 0.05), respectively. Moreover, annual mean temperature and the SWB exhibited a negative correlation (r = −0.244, p > 0.05) and correlation between SWB and total annual precipitation was positive (r = 0.535, p > 0.05). However, SCA of Gilgit Baltistan changed at the rate of −0.396% yr−1 (p < 0.05), −0.940% yr−1 (p < 0.05) and −0.253% yr−1 (p > 0.05) for annual, summer and winter, respectively. Furthermore, annual mean temperature and SCA exhibited a negative correlation (r = −0.731, p < 0.05), whereas annual total precipitation and SCA showed a positive correlation (r = 0.636, p < 0.05). These results indicated that climate had been significantly affected the SCA and SWB of the Gilgit Baltistan.","PeriodicalId":54618,"journal":{"name":"Physical Geography","volume":"44 1","pages":"600 - 619"},"PeriodicalIF":1.6,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43187917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
