Sustaining Himalayan Water Resources in a Changing Climate (SusHi-Wat)

在这个项目中，我们建议研究水是如何在印度北部的喜马拉雅河流系统（相互连接的Beas和Sutjej流域）中储存和流动的，以每日到十年的时间尺度，并利用由此产生的见解来开发和测试整个系统的强大模型，该模型可用于为当前和未来的决策提供信息，以支持该地区水资源的可持续发展和管理。在MICCI项目（在变化的水循环-南亚方案内）在该区域取得成功的基础上，该项目将满足用户的需求，重点是了解和管理气候和水文变化以及社会经济发展对提供关键生态系统服务的影响，特别是灌溉用水供应-水力发电-洪水风险管理关系。将发展最先进的模型、实地研究、基于卫星的遥感和观测的结合，以改进对喜马拉雅水资源可用性和质量的基于过程的了解，同时考虑到气象学、地表水、地下水、季节性雪、永久雪/冰、土壤和植被。这些存储和流将在明确承认其相互依赖和相互作用的“整个系统”框架中考虑。改进后的理解将用于使用广泛使用的水资源评估和规划（WEAP）软件系统建立、校准和验证一个强大的流域系统模型。这个模型将把“自然的”集水区过程和人类对流域系统的改变都考虑进去。后者包括灌溉、水力发电和跨流域调水。整个系统模型将用于了解气候变化、土地利用变化和人口增长的影响将如何影响水资源（包括洪水风险管理）、水需求（灌溉和公共用水需求）以及通过与水循环的相互作用对水供应（调水、灌溉和水电）的部门间竞争。研究结果将用于为决策提供信息，并支持印度水资源的可持续发展，从而促进长期的社会经济增长。该项目将涉及印度4个机构(印度理工学院-鲁尔基学院；NIT- Hamirpur，国家水文-鲁尔基研究所和印度科学研究所-班加罗尔)，2所英国大学（赫瑞瓦特大学和克兰菲尔德大学）和一个英国研究机构（英国南极调查局）。它将建立在许多英国和印度合作伙伴之间现有的蓬勃发展的合作基础上。我们将与印度主要的区域和国家利益攸关方（农民、农业顾问、流域管理委员会和全国农民协会）合作，确保研究的相关性和影响。

In this project, we propose to investigate how water is stored in, and moves through, a Himalayan river system (the inter-linked Beas and Sutjej catchments) in northern India at daily to decadal timescales and to use the resulting insights to 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. Building on the success of the MICCI project (within the Changing Water Cycle - South Asia programme) in the region, the project will address user requirements centred on understanding and managing the effects of climatological and hydrological variability and socio-economic development on delivery of critical ecosystems services, notably the irrigation water supply-hydropower generation-flood risk management nexus.A combination of state-of-the-art modelling, field studies, satellite-based remote sensing and observation will be developed to improve the process-based understanding of Himalayan water resources availability and quality, considering meteorology, surface-water, groundwater, seasonal snow, permanent snow/ice, soil and vegetation. These stores and flows will be considered within a 'whole-system' framework that explicitly recognises their inter-dependencies and interactions.The improved understanding will be used to set-up, calibrate and validate a robust system model of the river basins using the widely used Water Evaluation And Planning (WEAP) software system. This model will integrate both 'natural' catchment processes and human modifications of the river basin system into account. These latter include irrigation, hydropower generation, and inter-basin water transfers. The whole system model will be used to understand how the impact of climate change, land-use change and population growth will affect water resources (including flood risk management), water demand (irrigation and public water demand) and inter-sectoral competition for water supply (for water transfers, irrigation and hydropower) through their interactions with the hydrological cycle. The results will be used to inform decision-making and support the sustainable development of India's water resources and hence long-term socio-economic growthThe project will involve collaboration between internationally-leading scientists at 4 Indian institutions (IIT-Roorkee; NIT- Hamirpur, National Institute of Hydrology-Roorkee and the Indian Institute of Science- Bangalore), 2 UK Universities (Heriot-Watt University and Cranfield University) and one UK research institute (British Antarctic Survey). It will build on an existing and thriving collaboration between many of the UK and Indian partners. We will work with key regional and national stakeholders in India (farmers, agricultural advisers, river basin management board and the national farmers association) to ensure the relevance and impact of the research.
