Goal and objectives of the project

• Establishing a scientific basis for determining the reasonable distribution of pollution sources and calculating the maximum daily pollution load with numerical models that take into account the different self-cleaning processes and types of waste sources.
• Determining the maximum daily load for organic and nutrient pollution for some river segments in Cau river basin.
• Proposing a procedure for calculating the maximum pollution load and the suggested solution for water quality management in the Cau river basin.

Main results
- Theoretical results:
(1) Obtain analytical solution for the problem of optimal distribution of pollution sources on a river segment taking into account the effect of turbulence diffusion and self-cleaning of pollutants.
(2) Establish a scientific basis for determining the maximum daily pollution load on the basis of numerical models.
- Applied results:
(1) Proposing a procedure for calculating the maximum daily pollution load on the basis of numerical models.
(2) Determining the maximum daily pollution load for BOD, COD, TN and TP for 07 river segment on Cau river main stream from Cho Moi to Pha Lai.
