The utility model discloses a hydrogeological survey water flow testing device, which relates to the field of water flow testing and comprises a base, a horizontal component arranged at the top end of the base, a supporting frame arranged on the outer side of the top of the horizontal component and matched with the base, and a movable seat arranged at the top end of the horizontal component and matched with the supporting frame. An adjusting assembly is arranged on one side of the top end of the movable seat, a movable plate matched with the movable seat is arranged on one side of the adjusting assembly, and a tester is arranged at the top end of the movable plate. Under the matching action of the horizontal assembly, the adjusting assembly and the tester, key parameters such as the water flow speed, the flow direction and the flow rate can be stably and accurately measured, the exploration accuracy is improved, the distribution and change rules of the underground water level can be understood, and the underground water level measuring instrument is suitable for popularization and application. And a scientific basis can be provided for water resource management, water resource development and environmental protection, so that planning and implementation of hydrogeological engineering are effectively guided.

The present application belongs to the field of water resources development and prevention technology, and specifically relates to a test device and method for determining the direction of fissure dominant seepage, comprising a water injection system for injecting tracer solution into the fissure and a multi-directional conductivity monitoring system for obtaining the borehole, the water injection system comprising a tracer supply device and a borehole target depth water injection device, and the multi-directional conductivity monitoring system being used for real-time recording and display of the multi-directional groundwater tracer concentration in the borehole. The direction of fissure dominant flow at any depth is determined according to the vector synthesis of conductivity in different directions. The method is simple and easy to operate, has high operability, and can quickly and efficiently determine the direction of fissure dominant flow, thereby providing a theoretical basis and technical support for the fields of underground resource development and utilization, groundwater resource assessment and protection, environmental engineering, geological disaster prevention, and geothermal energy development.

The invention provides a lake ecological flow processing method and a lake ecological flow processing device based on a remote sensing and water balance model, which are used for establishing a set of lake ecological flow standardization processing architecture based on a remote sensing and water balance equation, effectively solving the limitation that the traditional method seriously depends on actually measured hydrological data, and reducing the calculation cost. Meanwhile, compared with the characteristic that long-term data accumulation is needed in a traditional method, the timeliness is remarkably enhanced, so that the application requirements of low cost and rapid evaluation can be met, and good data support is provided for lake water resource development and utilization management and control and lake ecological management work.
