11. Summary of the new findings of the thesis

- Environmental changes of Son La hydropower reservoir were analyzed clearly in the period 2014-2019 including: fluctuation of water quality, hydropower reservoir erosion and sedimentation, material balance changes of self-cleaning capacity and load capacity of the hydropower reservoir.

- Primarily quantified the multi-purpose use values of Son La hydropower reservoir in the period 2013 – 2019, on that basis building a multi-criteria set of indicators to evaluate the model and propose solution for the sustainable use and management of natural resources and environmental protection in Son La hydropower reservoir.

12. Practical applicability, if any:

- The research results on environmental changes after storing water are highly applicable to sedimentation management, water quality management, self-cleaning capacity management, and hydropower reservoir’s load capacity management.

- The research results of the multi-criteria set of indicators might have additional practical basis for industries, sectors, localities to manage the sustainable use of the hydropower reservoir resources and environment. 

13. Further research directions, if any:

- Experimental study to verify the fluctuations range of Nitrogen and Phosphorus loading into the lake by data: population, livestock, cage fish farming, semi-inundation land, air settling, inflow and outflow of water, evaporation of N and P. Result might indicate parameters affecting to water changes, and recommend the monitoring and analyzing of parameters.

- Experimental study to determine erosion rate of pollution parameters such as: BOD, COD, total N, P, NH₄⁺, NO₂^-, NO₃^-, PO₄^3- from the group of pollution sources into the lake.

- Further research and develop a multi-criteria set of indicators to be a set of standards for integrated environmental and natural resources management to support solutions for management, exploitation and rational use of natural resources and environmental protection of Son La hydropower reservoir.

- Research and apply green development model on electricity production, aquaculture, semi-inundation agriculture, ecotourism, and fishing activities of the Son La hydropower reservoir.
