“…We thank the commentator for his comments on our paper (Dar et al, 2014) in press, hereinafter referred to as Dar et al (2015). Standard procedures were followed for correlation of lithostratigraphic units and interpreting each of the profile in terms of depositional system using key macro and micro-morphological features (Bullock et al, 1985;Retallack, 1988;Agrawal et al, 1989;Kukla and An, 1989;Pant, 1993;Stoops, 2003).…”

“…The focus of the research is primarily about assessing the impacts of differential geomorphology, lithology and land cover on flood vulnerability of the two watersheds located on the Pir Panjal and Greater Himalaya range. The tectono-geomorphic evolution of KB, nestled between the Pir Panjal range and the Greater Himalaya range, has been studied to understand its tectono-geomorphic evolution and stands published by one of the coauthors (Dar et al 2015). The authors have meticulously discussed the sequence of the events of the Karewa lake formation and its draining out during the era when the homo sapiens did not even inhabit the earth.…”

Assessing the influence of watershed characteristics on the flood vulnerability of Jhelum basin in Kashmir Himalaya: reply to comment by Shah 2015

et al. 2015

We thank the commentator for his comments on our manuscript. The original manuscript published by Meraj et al. (2015) focused on the influence of the geomorphology and land cover on flood vulnerability in two Himalaya watersheds: one each from the Pir Panjal and Greater Himalaya ranges. The 2014 floods were mentioned in the manuscript just to indicate the validity and correctness of the approach adopted to assess the vulnerability of these two watersheds in Kashmir basin (KB). KB is also synonymously used for Karewa basin or Jhelum basin as well. The downstream areas of both these watersheds were inundated during the 2014 floods up to varying depths and duration. The September 2014 floods in the KB were a consequence of the extreme rainfall event that was quite widespread in extent. The situation was exacerbated due to the loss of wetlands, unplanned urbanization, the siltation of water courses in KB and the inadequate flood control infrastructure (Romshoo 2015). The commentator has made most of the comments about the genesis of 2014 floods, which was not specifically the focus of the research published by Meraj et al. (2015), and hence the genesis of the 2014 floods was not addressed therein. It is therefore appropriate that the comments made in Shah (2015) are properly responded to point by point, in order to provide a balanced perspective to the readership of the journal, and are as follows:This reply refers to the comment available at

The conventional approach of using modern values of lake hydrochemistry and sediment composition as key parameters for identifying proxies for environmental reconstruction is complicated by regional climate, catchment geology, lake morphometry and anthropogenic input. In contrast to modern studies from lakes in the north‐temperate regions, reliable proxy indicators for past environmental change from tropical lake systems are still lacking. In this study, we compare new surface geochemical and mineralogical data from the Manasbal Lake, Kashmir (India), with other lakes situated in climatically and geomorphologically distinct regimes with varying degrees of pollution (Tso Moriri in north‐western Himalaya and Lonar in central India). We characterise external (e.g., geology and weathering), internal (e.g., lake water mixing and evaporation) factors and human activities influencing sediment composition and spatial distribution of proxies in each of these lakes to evaluate the usefulness of some of the commonly used proxies, as well as ascertain conditions where they might be applicable. Our results show that (i) morphometric parameters (such as lake size, water depth and catchment vs. lake area) variably influence the spatial distribution of sediments and proxies on the lake bottom highlighting the limitations of using single cores for long‐term palaeoclimate reconstruction; (ii) hydrochemical proxies (such as Na+/Na++Ca2+ and Mg/Ca) can delineate endogenic (Lonar and Tso Moriri lakes) versus allogenic (Manasbal Lake) influence on modern sediment characteristics; (iii) the compilation of heavy metal data (e.g., Fe, Zn, Mn, Cr and Ni) from all three lake basins with varying degrees of pollution highlights the limitations of using them to characterise weathering conditions in these basins; and (iv) human impact must be precluded before using the most promising endogenic minerals (calcite, aragonite, gypsum and pyrite) as palaeoenvironmental/palaeoclimate indicators.
