GlobalReservoirModel V1.0-V1.3 A new global reservoir modeling database

We introduce a new 2D/3D global modelling reservoir database called GRM-Global Reservoir Model, which integrates data from the following existing global databases: Global Reservoir and Dam database (GRanD), Reservoir Storage-Area-Depth dataset (ReGeom), WaterGAP V2.2D, FutureStreams, and ERA5 reanalysis databases. GRM generates simplified reservoir bathymetries, based on variable, user-defined segments. It further provides long-term water discharge (from 1980 to 2000), water temperature (from 1980 to 2000), and daily meteorological data (from 1980 to 2000) in model usable output files. The GRM output files can be directly implemented into popular water quality models such as CE-QUAL-W2 through GRM concurrent computing code. As such, GRM overcomes the usual gap between existing global reservoir datasets and water quality modelling research. This sets the stage for using GRM in applications looking at potential biogeochemical responses in global reservoirs and other freshwater systems due to climate change.

本团队推出一款名为GRM-Global Reservoir Model的全新二维/三维全球建模水库数据库，该数据库整合了以下现有全球数据库的数据：全球水库与水坝数据库（GRanD）、水库储存-面积-深度数据集（ReGeom）、WaterGAP V2.2D、FutureStreams以及ERA5再分析数据库。GRM基于可变、用户定义的段落生成简化的水库地形，并进一步提供长期的水流量（1980年至2000年）、水温（1980年至2000年）以及每日气象数据（1980年至2000年），并以模型可用的输出文件形式提供。GRM的输出文件可被直接应用于如CE-QUAL-W2等流行水质模型，通过GRM并行计算代码实现。因此，GRM弥合了现有全球水库数据集与水质建模研究之间的常规差距。这为在气候变化影响下，全球水库及其他淡水系统中潜在的生物地球化学响应的应用研究奠定了基础。
