Surface water source fractions and hydraulic heads for Biebrza River Catchment in water year 2002

This dataset is a result of integrated hydrological modelling with the HydroGeoSphere model and the Hydraulic Mixing-Cell method. Study area is the Biebrza River Catchment, however, the grid is refined only in the lower Biebrza floodplain. The hydraulic heads were verified based on water levels managed by Biebrza National Park and the water mixing zonation was verified using hydrochemical data. Data are stored in two .plt files. - biebrza.porous_media.plt contains the 3D time-variant hydrological variables for the porous media (groundwater domain) - biebrza.overland_flow_and_mixing.plt contains the 2D time-variant hydrological variables, including the water sources HMC fractions, for the surface water (surface water domain) The .plt files are binary, they can be opened using TecPlot 360 (commercial software) or ParaView (open software).本数据集为采用HydroGeoSphere模型（HydroGeoSphere）与水力混合单元法（Hydraulic Mixing-Cell method）开展集成水文模拟的成果。研究区域为别布扎河流域（Biebrza River Catchment），但仅针对别布扎河下游泛滥平原区域实施了网格加密。水力水头通过别布扎国家公园管理的水位数据完成验证，水混合分区则借助水化学数据进行校验。数据集存储于两个.plt格式文件： - biebrza.porous_media.plt：包含多孔介质（地下水域）的三维时变水文变量； - biebrza.overland_flow_and_mixing.plt：涵盖地表水水域的二维时变水文变量，其中包含水源HMC组分占比。 上述.plt格式文件均为二进制文件，可通过商业软件TecPlot 360或开源软件ParaView打开。
