Calculation methods of technical-economic norms for hydrological stations in Vietnam

01:05, 11/07/2024

This is a notable content stipulated in Circular 36/2016/TT-BTNMT regulating the technical-economic norms for the operation of the hydrometeorological station network.

According to the provisions of Circular No. 36/2016/TT-BTNMT, the calculation of technical-economic norms for hydrological stations in Vietnam through the adjustment coefficient is as follows:

M = Mc x k

Where:

- M is the actual norm;

- Mc is the norm given under standard conditions;

- k is the adjustment coefficient for the complexity affecting the standard norm.

Where, the adjustment coefficients include the adjustment coefficient for labor norms, the adjustment coefficient for equipment norms, the adjustment coefficient for tool norms, and the adjustment coefficient for material norms. Thus, tthe adjustment coefficient for labor norms includes:

Water level measurement:

- Freshwater region with the coefficient khn

No	Hydrological structure, water level measurement equipment	k_hn
1	Water level observation using markers and water stages	1.00
2	Water level observation using self-recording devices	0.98
3	Water level observation using automatic equipment, automatic data transmission	0.07

- Tidal region with the coefficient kht

No	Hydrological structure, water level measurement equipment	k_ht
1	Water level observation using markers and water stages	2.39
2	Water level observation using self-recording devices	0.98
3	Water level observation using automatic equipment, automatic data transmission	0.07
