Hydrological Monitoring of Puhe River in Chongqing
This paper presents the results of a study on the hydrological monitoring of Puhe River in Chongqing, China. The study focused on the construction of a hydrological monitoring system, including a network of monitoring stations, data acquisition and processing, and a monitoring data management system. The aim of the study was to evaluate the current status of water quality and quantity in Puhe River, to identify potential threats to water resources, and to propose measures for improving water quality and quantity. The results of the study indicate that Puhe River is subjected to varying degrees of pollution, with industrial wastewater being the main source of pollution. In addition, there are deficiencies in water resources management, such as inadequate wastewater treatment facilities and a lack of effective water resources protection policies. To address these issues, it is recommended that the government strengthen its efforts to protect water resources, improve wastewater treatment facilities, and implement effective water resources management policies.
Chongqing, a megacity in Southwest China, is home to various ecosystems and water bodies, including the Puhe River. The Puhe River, one of the important tributaries of the Yangtze River, plays a crucial role in Chongqing’s water supply, irrigation, and transportation. Given its significance, it is essential to conduct regular monitoring of the Puhe River’s hydrology to ensure sustainable use and protect the environment. This article provides an overview of the current status of Puhe River’s hydrological monitoring.
The first step in monitoring the Puhe River is to establish monitoring stations along the river. These stations collect data on water level, flow rate, and water quality. By doing so, they provide valuable information for understanding the river’s natural characteristics and human impact on it. The Chongqing government has been proactive in establishing these stations, with several located along the Puhe River.
The next step is to use appropriate techniques to measure and evaluate the water quality of the Puhe River. This involves testing the water for various pollutants, such as heavy metals, organic compounds, and microbial contaminants. The government has set strict standards for water quality, and the monitoring stations regularly check if the river meets these standards. If the water quality does not meet the standards, the government can take necessary measures to improve it.
Moreover, modern technology has made it possible to monitor the Puhe River remotely using satellite images and other sensors. These remote sensing techniques provide a broader picture of the river’s condition, including its physical features, water quality, and pollution levels. By combining these techniques with traditional monitoring methods, researchers can get a comprehensive understanding of the Puhe River’s hydrology.
However, challenges remain in Puhe River’s hydrological monitoring. One major challenge is that the river’s flow rate and water level can vary significantly due to natural factors like rainfall and snowmelt. This variability makes it difficult to predict the river’s behavior accurately. Another challenge is that human activities, such as industrial pollution and agricultural runoff, can significantly impact the Puhe River’s water quality. Monitoring these activities is essential to protect the river from pollution.
In conclusion, the hydrological monitoring of the Puhe River in Chongqing is crucial for understanding the river’s natural characteristics and human impact on it. The government has been proactive in establishing monitoring stations and using appropriate techniques to measure and evaluate water quality. However, challenges remain due to natural factors and human activities. By using remote sensing techniques and combining them with traditional monitoring methods, researchers can get a comprehensive understanding of the Puhe River’s hydrology and protect it from pollution.
