Technical regulations for monitoring xem bóng đá trực tiếp trên youtube in rivers not affected by tides in Vietnam

Hello, Lawnet would like to answer as follows:

1. Technical regulations for monitoring xem bóng đá trực tiếp trên youtube in rivers not affected by tides in Vietnam

According to the provisions in subsection 1.1 of Appendix BQCVN 47:2022/BTNMTon the monitoring regime, as follows:

For principles of arranging monitoring regime:

a) Depending on the flow regime and hydraulic regime at the monitoring location and the need to use data, arrange the monitoring regime appropriately to ensure it reflects the xem bóng đá trực tiếp trên youtube evolution at the measurement location.

b) There are two forms of xem bóng đá trực tiếp trên youtube monitoring: regular monitoring and inspection monitoring.

- Regular monitoring means measuring for many consecutive years. The xem bóng đá trực tiếp trên youtube monitoring regime, in the form of regular monitoring, ensures the following principles:

+ The arrangement of the xem bóng đá trực tiếp trên youtube monitoring regime according to water level, time, flood characteristics, or special hydraulic developments must be based on the purpose, monitoring requirements, and operating time of the station;

+ The number of flow measurements per year is enough to control the representativeness and characteristic points of the correlation between water level and xem bóng đá trực tiếp trên youtube Q = f(H) from low to high;

+ The number of flow measurements per year is enough to determine the correlation between water level and xem bóng đá trực tiếp trên youtube Q = f(H) according to the hydraulic influence regime, including special cases such as dyke breaks, beach overflows, etc.;

- Monitoring and checking is done every year or a number of years, measuring a number of flow measurements according to certain xem bóng đá trực tiếp trên youtube levels or certain floods.
to check the change in water level and xem bóng đá trực tiếp trên youtube relationship Q = f(H).

Regarding monitoring regime

xem bóng đá trực tiếp trên youtube monitoring regimes for new stations operating less than 3 years, stations operating over 3 years, and stations operating over 5 years is implemented according to the provisions of Article 7.2 in TCVN 12636-8:2020 Hydro-meteorological monitoring - Part 8: Monitoring river xem bóng đá trực tiếp trên youtube in areas not affected by tides.

2. Method for measuring the volume of xem bóng đá trực tiếp trên youtube in rivers that are not affected by tides in Vietnam

According to the provisions in subsection 1.2 of Appendix BQCVN 47:2022/BTNMTon volume measurement method, as follows:

Principles for choosing monitoring methods

- The choice of xem bóng đá trực tiếp trên youtube monitoring method must be based on the purpose, station location requirements, and specific situation at each time and at each monitoring location;

- Multiple methods can be used separately or in combination to monitor xem bóng đá trực tiếp trên youtube, but they must ensure the principles of accuracy and economy.

Conditions for applying the volume measurement method

The volume measurement method is applied in small rivers and streams where there is no stagnant water and where the cross-section can be improved to collect xem bóng đá trực tiếp trên youtube into the trough with a maximum xem bóng đá trực tiếp trên youtube of 20 l/s.

Volume measurement method

a) Measurement sequence

- Measure xem bóng đá trực tiếp trên youtube level;

- Determine measurement time;

- Measure xem bóng đá trực tiếp trên youtube volume;

- Calculate xem bóng đá trực tiếp trên youtube;

- Maintenance of vehicles and measuring equipment.

b) Measurement method

- Must measure the water level at the measurement location at the beginning and end of xem bóng đá trực tiếp trên youtube measurement;

- Determine measurement time:

+ Record the start time and end time of measurement to the nearest second;

+ Measurement time is calculated as the difference between the end of measurement and the start of measurement.

- Measure xem bóng đá trực tiếp trên youtube volume: must ensure to capture the entire amount of xem bóng đá trực tiếp trên youtube flowing through the cross section from the start to the end of the measurement; xem bóng đá trực tiếp trên youtube containers must be safe and convenient to determine the volume of xem bóng đá trực tiếp trên youtube, and they must not be filled with too much xem bóng đá trực tiếp trên youtube to avoid overflowing during operation;

- Observe and record weather phenomena, flow conditions, and phenomena affecting the flow, such as river banks, river bottoms, and vegetation growing in the river bed and river banks.

Calculate xem bóng đá trực tiếp trên youtube

The xem bóng đá trực tiếp trên youtube measured by the volumetric method is calculated as follows:

Q = W/∆t

In there:

- Q is xem bóng đá trực tiếp trên youtube (l/s);

- W is the volume of xem bóng đá trực tiếp trên youtube (l);

- ∆t is the measurement time (s);

- ∆t = t2 - t1

- t2 is the end of measurement;

- t1 is the starting time of measurement.
