    Enhancing production and flow of freshwater ecosystem services in a managed Himalayan river system under uncertain future climate
    (Springer, 2020-08-29) Momblanch, Andrea; Beevers, Lindsay; Srinivasalu, Pradeep; Kulkarni, Anil; Holman, Ian P.
    Future climate change will likely impact the multiple freshwater Ecosystem Services (fES) provided by catchments through their landscapes and river systems. However, there is high spatio-temporal uncertainty on those impacts linked to climate change uncertainty and the natural and anthropogenic interdependencies of water management systems. This study identifies current and future spatial patterns of fES production in a highly managed water resource system in northern India to inform the design and assessment of plausible adaptation measures to enhance fES production in the catchment under uncertain climate change. A water resource systems modelling approach is used to evaluate fES across the full range of plausible future scenarios, to identify the (worst-case) climate change scenarios triggering the greatest impacts and assess the capacity of adaptation to enhance fES. Results indicate that the current and future states of the fES depend on the spatial patterns of climate change and the impacts of infrastructure management on river flows. Natural zones deliver more regulating and cultural services than anthropized areas, although they are more climate sensitive. The implementation of a plausible adaptation strategy only manages to slightly enhance fES in the system with respect to no-adaptation. These results demonstrate that water resource systems models are powerful tools to capture complex system dependencies and inform the design of robust catchment management measures. They also highlight that mitigation and more ambitious adaptation strategies are needed to offset climate change impacts in highly climate sensitive catchments

    Integrating glacier flow in hydrological modelling for water resources management
    (EGU: European Geophysical Union, 2022-05-27) Momblanch, Andrea; Shirsat, Tejal; Kulkarni, Anil; Holman, Ian P.
    The climate emergency will drive changes in the cryosphere and hydrology of high mountain catchments, with subsequent influences on water resources availability. Process-based hydrological and glaciological models require significant amounts of data which are often unavailable in high mountainous catchments, especially in developing countries, and are unable to explicitly integrate human-induced factors on river flows (Momblanch et al. 2019). This can be overcome by water resources systems models that take a more conceptual approach. However, they currently have limited capability to represent glacier evolution and thus river discharge dynamics, especially in long-term simulations required for climate change impact and adaptation analysis. There is, therefore, a clear need for improved representation of the spatio-temporal response of glaciers within water resources systems models to support the strategic water resources planning and management and ensure future water security.

    SusHi-Wat: Output of Beas-Sutlej basins systems model
    (Cranfield University, 2018-11-28 11:43) Momblanch Benavent, Andrea; Holman, Ian; Papadimitriou, Lamprini; K. Jain, Sanjay; Kulkarni, Anil; SP Ojha, Chandra; J Adeloye, Adebayo
    This work has been developed under the project 'Sustaining Himalayan Water Resources in a Changing Climate' (SusHi-Wat), which aims at improving understanding of how water is stored in, and moves through, a Himalayan river system in northern India (the inter-linked Beas and Sutlej catchments) and develop and test a robust model of the whole system that can be used to inform current and future decision making to support the sustainable development and management of the region's water resources.The dataset contains the monthly time series of selected output of a water resource systems model built with the Water Evaluation And Planning (WEAP) software for the Beas and Sutlej basins, under different climate and socio-economic scenarios. It was used to derive the results presented in the paper "Untangling the water-food-energy-environment nexus for global change adaptation in a complex Himalayan water resource system", https://doi.org/10.1016/j.scitotenv.2018.11.045.Detailed description of the files:'0.Runoff summary.xlsx' - Monthly time series of the total runoff generated upstream Pong and Bhakra reservoirs for the baseline scenario and two climate change scenarios. The column headings correspond to different sub-basins and elevation bands as described in the corresponding paper.'1.WEAP results_Baseline.xlsx'; '1.WEAP results_CC3&SSP1.xlsx'; '2.WEAP results_CC3&SSP2.xlsx'; '3.WEAP results_CC3&SSP5.xlsx'; '4.WEAP results_CC7&SSP1.xlsx'; '5.WEAP results_CC7&SSP2.xlsx'; '6.WEAP results_CC7&SSP5.xlsx' - Monthly time series of several WEAP outputs under different climate and socio-economic change scenarios, i.e. urban demand supply coverage, irrigation demand supply coverage, hydropower energy production, water stored in reservoirs, river flows downstream Pandoh dam, glacier depth, total runoff, snow melt runoff, ice melt runoff, actual evapotranspiration. The column headings correspond to water demands, management infrastructures and sub-basins and elevation bands as described in the corresponding paper.
