项目摘要

TITLE: Coupling a physically-based, spatially distributed hydrological model with an Open Data Cube (ODC) ecosystem as data repository and analysis tool to quantify the impacts of climate change in water security.For many areas across the globe physically-based hydrological models have a fundamental role helping devise a comprehensive and robust plan for future climate change adaption and preparedness, informing water management and flood initiatives, as well as enhancing knowledge of local and regional hydrological processes. Whilst the use of physically-based hydrological models have been restricted by the nature of the process i.e. large data volumes and greater computational resources required (Lewis et at., 2018), recent advances on satellite derived analysis ready data (ARD) availability and computational environments (online and local deployments) have served as catalyst to a wider use of these models (Sun et al., 2019, Saran et al., 2021).In this context, this research has the purpose to examine the effects of climate change on water security through the application of the open and freely available earth observation satellite data architecture made available by the Open Data Cube project (https://www.opendatacube.org) in conjunction with the SHETRAN model (Ewen et al., 2000) utilising a freely available computation environment (JupyterHub). This research will be expected to contribute towards the implementation and adaptation strategies of the Sustainable Development Goals (SDG's), in particular SDG 6 (clean water and sanitation), SDG 11 (Sustainable cities and communities) and SDG 13 (climate action).

题目：将基于物理的、空间分布的水文模型与开放数据立方体（ODC）生态系统相结合，作为数据存储库和分析工具，量化气候变化对水安全的影响。对于全球许多地区来说，基于物理的水文模型在帮助制定全面而有力的未来气候变化适应和准备计划、为水管理和洪水举措提供信息以及增强对地方和区域水文过程的了解方面发挥着重要作用。虽然基于物理的水文模型的使用受到过程性质的限制，即数据量大，需要更多的计算资源（Lewis等）。， 2018)，卫星衍生分析就绪数据（ARD）可用性和计算环境（在线和本地部署）的最新进展促进了这些模型的广泛使用（Sun等人，2019，Saran等人，2021）。在这种背景下，本研究的目的是通过应用开放数据立方体项目（https://www.opendatacube.org）提供的开放和免费的地球观测卫星数据架构，结合SHETRAN模型（Ewen等人，2000），利用免费提供的计算环境（JupyterHub），研究气候变化对水安全的影响。这项研究将有助于可持续发展目标（SDG）的实施和适应战略，特别是可持续发展目标6（清洁水和卫生）、可持续发展目标11（可持续城市和社区）和可持续发展目标13（气候行动）。
