First GLORIA Site in Indian Himalayan Region: Towards Addressing Issue of Long-Term Data Deficiency in the Himalaya

Cost effective, safe and long term sustainable hydropower development is key for the lasting economic growth in the Himalayan region. Increasing pressure towards the use of renewal and environmentally friendly energy for industrial growth and daily household use will force the Himalayan region to exploit hydropower energy more extensively. The traditionally used design approach of fully lined underground waterway system is costly and financially unfeasible as well as an obstacle to attract investment in the hydropower sector in the Himalaya. Hence, more innovative solutions are needed to make hydro generated energy more cost effective and as a sustainable energy solution in the long term. This paper briefly describes the geological set-up of Scandinavia, history of Norwegian Hydropower and reviews the design principle used to develop the underground waterway system in Norway. Brief comments are also made on the applicability of these principles in the Himalayan region. It is anticipated that more discussions will be made in the future on the geo-tectonic environment of the Himalaya and suitability of Norwegian design principle in the Himalayan region.DOI: http://dx.doi.org/10.3126/hn.v14i0.11254HYDRO Nepal JournalJournal of Water, Energy and EnvironmentVolume: 14, 2014 JanuaryPage: 36-40

The Himalaya

Geranium rubifolium (Geraniaceae) has been rediscovered while conducting floristic sampling for the monographic studies on the genus Geranium from Indian Himalayan region. The species was described 179 years ago by John Lindley by using Iconotype, serving as the type and the only known material of the taxon. The locality of Lindley’s collection (collection made by Dr. Royle) is imprecisely described, as he only mentioned ‘the Himalaya’ where the taxon is found. Therefore any search attempt would require an extensive exploration of the Indian Himalayan region. Morphological variation of G. rubifolium has been poorly understood because of the non-availability of representative specimen. Consequently, after rediscovering the taxon, we provide here the detailed taxonomic description, notes on habitat, distribution and its conservation status.

The Himalaya

The Himalaya, the youngest and the tallest folded mountain range of the world, is frequently affected by natural disasters.18 In the form of flash floods, cloudbursts or glacial lake outburst floods, the entire Himalayan region is highly vulnerable to natural hazards. In this context, the State of Uttarakhand of the Indian Himalayan Region has been the most vulnerable one among all the natural disaster-affected states in India.

This study presents a hydrogeochemical analysis of spring responses (2013-2017) in the tropical mountainous region of the Central Valley of Costa Rica. The isotopic distribution of δ18O and δ2H in rainfall resulted in a highly significant meteoric water line: δ2H = 7.93×δ18O + 10.37 (r2=0.97). Rainfall isotope composition exhibited a strong dependent seasonality. The isotopic variation (δ18O) of two springs within the Barva aquifer was simulated using the FlowPC program to determine mean transit times (MTTs). Exponential-piston and dispersion distribution functions provided the best-fit to the observed isotopic composition at Flores and Sacramento springs, respectively. MTTs corresponded to 1.23±0.03 (Sacramento) and 1.42±0.04 (Flores) years. The greater MTT was represented by a homogeneous geochemical composition at Flores, whereas the smaller MTT at Sacramento is reflected in a more variable geochemical response. The results may be used to enhance modelling efforts in central Costa Rica, whereby scarcity of long-term data limits water resources management plans.

Brine Salinity

The long-term data from morphometric studies of Artemia males from bisexual and parthenogenetic populations from hyperhaline reservoirs of the Altai region (Bolshoe Yarovoe Lake, Maloe Shklo Lake, and the Tanatar Lakes system) is analyzed in this paper. The description of signs of sexual dimorphism and sexual structure in different populations is given. The influence of brine salinity and hydrogen index on morphometric parameters of males was analyzed. There are differences in the sexual structure of the Artemia population: in the lakes Maloe Shklo and the thanatar system, the populations are bisexual (the share of males is 28.5 — 75.0 %), in the lake Bolshoe yarovoe — parthenogenetic (the share of males on average does not exceed 3 %). At the same time, sexual dimorphism is typical for both types of populations: females are larger than males, males have a larger head (the distance between the eyes is greater by 15.5 %, the diameter of the eye is 26.1 %, the length of the antenna is 22.3 %) and a larger number of bristles (36.1 %). The greatest variability is observed in the parameters of the Furka structure associated with the salinity of water by feedback and the pH — line indicator. Significant differences between the samples of males were revealed. The largest number of significant differences in morphometric indicators was found between samples of males from bisexual populations (lake thanatar and lake Maloe Shklo), the smallest — between males from the parthenogenetic population of lake Bolshoe yarovoe and males from lake Maloe Shklo.
