Dataset for Earth Observations-Informed Modelling for the Design of Nature-Based Climate Adaptation Strategies

This dataset accompanies the study ‘Earth Observations-Informed Modelling for the Design of Nature-Based Climate Adaptation Strategies’ and contains outputs from the MIKE SHE distributed hydrological model of a transboundary catchment Aa of Weerijs, situated between Belgium and the Netherlands. The data is organized into three main components based on the objectives of the study:1) Precipitation Dataset Evaluation: The purpose was to evaluate the impact of different Earth Observation precipitation products on modelled discharge and groundwater levels and to formulate the framework to identify the best suitable precipitation product for hydrological simulations. The precipitation datasets used were 1) ERA5 land, 2) MSWEP, 3) IMERG Final and 4) EOBS. The simulated discharge time series at three locations and groundwater levels at 13 locations are compared and data is provided in folder ‘Precipitation_datasets_evaluation’.2) Climate and Land Use Change Impact Analysis: The purpose was to analyse the individual and combined effect of climate and land use change on actual evapotranspiration, soil moisture, discharge and groundwater levels of the catchment. The results are provided in the folder ‘Climate_change_and_landuse_change_analysis’. 3) Nature based climate adaptation strategies: The purpose was to evaluate the effect of six different nature-based solutions (NBS) on discharge and groundwater levels. Further, two different nature based adaptive strategies were formulated and their impact on the discharge and groundwater levels were assessed. The data is provided in the folder ‘NBS_strategies’

本数据集配套于研究论文《基于地球观测（Earth Observation）建模的自然气候适应策略设计》，包含位于比利时与荷兰之间的韦赖斯阿河（Aa of Weerijs）跨界流域的MIKE SHE分布式水文模型模拟结果。本数据集根据研究目标分为三大核心模块：
1) 降水数据集评估：本模块旨在评估不同地球观测降水产品对模拟径流与地下水位的影响，并构建筛选适配水文模拟最优降水产品的框架。本次研究使用的降水数据集包括：1) ERA5 Land、2) MSWEP、3) IMERG Final、4) EOBS。本部分对3个监测点的模拟径流时序与13个监测点的地下水位进行了对比分析，相关数据存储于文件夹"Precipitation_datasets_evaluation"中。
2) 气候与土地利用变化影响分析：本模块旨在分析气候与土地利用变化各自及联合作用对流域实际蒸散发、土壤含水量、径流与地下水位的影响。相关研究结果存储于文件夹"Climate_change_and_landuse_change_analysis"中。
3) 自然气候适应策略：本模块旨在评估6种不同基于自然的解决方案（nature-based solutions, NBS）对径流与地下水位的影响。此外，本研究还构建了2种不同的自然适应策略，并评估其对径流与地下水位的调控效果。相关数据存储于文件夹"NBS_strategies"中。
