DETAILED DESCRIPTION

[0020] The utility model will be further explained in combination with the drawings and examples.

[0021] River runoff refers to the water quantity through a certain cross section of a river in a certain period, and the unit is generally cubic meters per second (m 3 / s) or other volume units combined with time units, which is an important index for measuring the amount of river water.

[0022] Runoff refers to the water flow that collects along different paths of a watershed during the hydrological cycle and converges into rivers, lakes, marshes, and oceans. The size of river runoff is influenced by various factors, including precipitation, evaporation, watershed area, topography, vegetation cover, etc. For example, in some areas, the annual runoff of rivers may show an increasing trend due to increased precipitation or decreased evaporation. Meanwhile, the number of tributaries and their water volume also affect the runoff of the main stream. For instance, although the Tarim River has numerous tributaries and abundant water, its average annual runoff of the main stream is relatively small, and even dry up, mainly due to specific geographical and climatic conditions.

[0023] River runoff monitoring devices are mainly used to monitor the changes in river flow in real time, as follows:

[0024] Water resources management

[0025] Reasonable allocation of water resources: Through accurate monitoring of river runoff, water resources departments can better allocate water resources. For example, in arid regions, accurate knowledge of river runoff helps determine the allocation of agricultural irrigation water. If runoff monitoring shows that the river is in a dry period, water resources management departments can appropriately reduce the allocation of agricultural irrigation water to prioritize domestic water use. Meanwhile, for cross-regional water transfer projects, runoff monitoring data can provide key evidence for determining the amount of water transfer to ensure the balance of water resources between the transfer-out area and the transfer-in area.

[0026] Assessment of total water resources: River runoff is an important part of the assessment of total water resources. Long-term data collected by monitoring devices can help calculate the average annual runoff of rivers in a certain area, thereby assessing the water resources endowment of that area. For example, when developing water resources development and utilization plans, it is necessary to determine how much usable water the river can provide, which relies on the data obtained by runoff monitoring devices for accurate calculation.

[0027] Flood control and disaster reduction

[0028] Flood warning: During the rainy season or heavy rain, river runoff will increase rapidly. Monitoring devices can monitor changes in runoff in real time and issue a flood warning when the runoff exceeds the safety threshold. For example, in urban areas where rivers pass through, runoff monitoring devices installed in the river channel transmit data to the flood control command center in real time. Once the flow approaches or exceeds the flow corresponding to the warning water level, residents can be notified in advance to prepare for flood prevention, such as evacuating residents in low-lying areas, reinforcing flood embankments, etc.

[0029] Flood Process Monitoring: During the occurrence of a flood, the monitoring device continuously monitors the dynamic changes of river runoff, helping flood control departments to grasp the evolution process of the flood. For example, according to the increasing or decreasing trend of runoff, it can be judged whether the flood peak has arrived, the size of the flood peak flow, and the recession process of the flood. These information has important reference value for reasonable scheduling of flood control resources, such as deciding whether to open the sluice to discharge flood, to use the flood storage area, etc.

[0030] Ecological Environment Protection

[0031] Maintaining River Ecological Health: The size and variation of river runoff have a profound impact on river ecosystems. Suitable runoff is one of the key factors for the survival and reproduction of aquatic organisms. For example, the reproduction of many fish species requires specific water flow speed and water level conditions. By monitoring runoff, we can understand whether these ecological needs are met. If the runoff is abnormal for a long time, it may lead to ecological problems such as destruction of fish habitats and reduction of aquatic plants. The data provided by the monitoring device can help take appropriate ecological restoration measures, such as adjusting the reservoir discharge to simulate natural runoff changes and create a suitable ecological environment for aquatic organisms.

[0032] Wetland Protection: River runoff is closely related to wetland ecosystems. Changes in runoff will affect the area and water depth of wetlands. Adequate runoff can replenish water in wetlands and maintain their ecological functions. The data from the monitoring device can support wetland protection. For example, when a wetland is at risk of drying up, monitoring data can be used to assess how much water needs to be replenished to maintain the stability of the wetland ecosystem, so that appropriate water replenishment measures can be taken.

[0033] Water Conservancy Engineering Construction and Operation

[0034] Engineering Planning and Design: Before constructing water conservancy projects such as dams and reservoirs, it is necessary to accurately understand the river runoff. Runoff data can help engineers determine key parameters such as dam height and reservoir capacity. For example, if the river runoff is large and has significant interannual variability, a larger-capacity reservoir needs to be designed to effectively regulate water and prevent flood disasters and ensure water use during dry periods.

[0035] Engineering Operation Scheduling: For water conservancy projects that have already been built, the data provided by the runoff monitoring device is crucial for the reasonable operation of the project. For example, for a reservoir, by monitoring the inflow and outflow of the river, management personnel can adjust the reservoir discharge strategy according to the actual situation. During the flood period, when the inflow runoff is large, increase the outflow (within the safety range) to prevent the reservoir from overflowing; during the dry period, reasonably control the outflow to ensure the ecological water and other water needs of the downstream.

[0036] River flow monitoring devices are essential as they provide critical data support for water resource management, flood control and disaster reduction, ecological environment protection, and water conservancy construction and operation, and are important tools for rational use of water resources and protection of ecological and life safety.

[0037] There are various types of river flow monitoring devices on the market, aiming to achieve real-time and accurate monitoring of river hydrological information. For example: 1. Radar flowmeter: by emitting microwave signals into the water flow, measuring the intensity and time delay of scattered signals to calculate the speed and flow of the water flow. Radar flowmeter is a non-contact measurement, suitable for wide river channels and complex terrain. Problems: Although radar flowmeter has the advantages of high precision and non-contact measurement, its cost is relatively high, and in some extreme weather conditions (such as heavy fog, heavy rain, etc.) the measurement accuracy may be affected. 2. Doppler flowmeter: based on the principle of Doppler effect, by emitting sound waves or ultrasonic waves into the water flow, measuring the frequency shift to calculate the speed and flow of the water flow. Doppler flowmeter is suitable for various water flow conditions, including high speed, low speed, shallow water and deep water, etc. Problems: Doppler flowmeter needs to directly contact the water flow, which may be affected by impurities, bubbles and other factors in the water, causing measurement data fluctuations. 3. Float-type flowmeter: by measuring the floating speed of the float in the river to calculate the river flow. Float-type flowmeter has the advantages of simple structure, easy to use, low cost, etc. Problems: The measurement accuracy of float-type flowmeter is relatively low, and it is affected by many factors such as river flow speed, flow direction, river channel shape, etc., suitable for small rivers and temporary measurement. 4. Electromagnetic flowmeter: based on the principle of electromagnetic induction, by installing electrodes in the river channel, measuring the current size formed when the river water flows through the electrodes, and calculating the river flow according to the known river cross-sectional area and electrode spacing. Problems: The installation and maintenance cost of electromagnetic flowmeter is high, and it has strict requirements on river shape and electrode spacing, suitable for long-term continuous monitoring occasions.
