Data set of simulation results of key hydrological variables in Zhangye basin of Heihe River Basin (1990-2012)

This project is based on the gsflow model of USGS to simulate the surface groundwater coupling in Zhangye basin in the middle reaches of Heihe River. The space-time range and accuracy of the simulation are as follows: Simulation period: 1990-2012; Simulation step: day by day; The spatial scope of simulation: Zhangye basin; The spatial accuracy of simulation: the underground part is 1km × 1km grid (5 layers, the total number of grids in each layer is 150 × 172 = 25800, among which the active grid 9106); the surface part is based on the hydrological response unit (HRU) (588 in total, each HRU covers an area of several square kilometers to dozens of square kilometers). The data include: surface infiltration, actual evapotranspiration, average soil moisture content, surface groundwater exchange, shallow groundwater level, simulated daily flow of Zhengyi gorge, simulated monthly flow of Zhengyi gorge, groundwater extraction and river diversion

本项研究基于美国地质调查局（USGS）的gsflow模型，旨在模拟黑河中游张掖盆地地表水与地下水的耦合作用。模拟的空间-时间范围及精度如下：模拟周期：1990-2012年；模拟步长：每日进行；模拟空间范围：张掖盆地；模拟空间精度：地下部分采用1km×1km的网格（共5层，每层网格总数为150×172=25800，其中活动网格数为9106）；地表部分则基于水文响应单元（HRU）进行（总计588个，每个HRU覆盖面积从数平方公里至数十平方公里不等）。数据包括：地表渗漏、实际蒸散量、平均土壤水分含量、地表水与地下水的交换、浅层地下水位、正谊峡谷模拟日流量、正谊峡谷模拟月流量、地下水开采及河流改道。
