Ninh Kieu and Cai Rang are two urban districts established in 2004 of Can Tho City. These are thriving
areas of the city and the Mekong Delta, with a long history of exploration and development. According to data
from the Statistics Office of Can Tho City in 2019, Ninh Kieu District has an average population of 280,792 people
and an area of 29.23 km2, while Cai Rang District has an average population of 105,547 people and an area of
66.81 km2. These two districts are currently facing major urban drainage challenges due to rapid urbanization.
To address these challenges, it is necessary to develop a mathematical model for the urban drainage system in
the study area, as a basis for providing appropriate solutions for drainage management. One of the important
input data for the mathematical model building process is the digital elevation model. This paper initiates the
preliminary results of building the digital elevation models based on Kriging interpolation method for Ninh Kieu
and Cai Rang districts. This is also a useful data for drainage management and environmental management in
the study area.
