Cat Tien-Da Teh drainage: dredging of Hai Co streams, Bo cones, Da R'Si to drain 5,100 ha. Dredging the R'Miss stream and tributaries, drainage for an area of 3,900 ha.
- Flood prevention and control: Construction of dikes downstream of Don Duong lake and drainage sluices to the Da Nhim river. Highway 721 in the areas along the rivers of Dong Nai in Cat Tien and Da Teh district to ensure seamless communication when the flood.
After planning, irrigation area in the whole Central Highlands reached 607,800 ha (reaching 52% of total area needed for irrigation, including 148,500 ha of rice, 299,700 ha of long-term industrial crops, color and other annual trees 159,600).
For the remaining area of 555,700 hectares, the following solutions will be studied:
- Exploiting groundwater within the allowable limits to expand irrigation for industrial crops;
- To build small dispersed reservoirs to increase the water storage capacity, to take initiative in irrigating irrigation water sources on the spot;
- Completing and extending the canal system to supplement irrigation water for dry areas, increasing irrigation area;
- Study to collect water from reservoirs for irrigation of sloping land along reservoirs and concentrated industrial trees;
- Review the reduction of paddy land area within the service area of irrigation systems in order to have more irrigation water for industrial crops;
- To step up the application of advanced irrigation, to save water in order to have more water sources to expand irrigation areas;
- Propagating and disseminating knowledge and advising local people to take initiative in restructure their crop plants in difficult regions and areas where irrigation water sources can not be located in these plannings;
- To study and promulgate mechanisms and policies, mobilize social resources, mechanisms to support local people to build small ponds and lakes, and complete the canal system.
c) Non-structure solutions
- Ensuring the safety of lakes, dams and irrigation works.
- Planting and protection of watershed forests and protection forests.
- Improving the efficiency of the management of exploitation and modernization in the management and operation of the irrigation system.
- To build and modernize the flood, drought and disaster prediction and warning system; To raise the capacity of medium and long-term forecasting for the operation of irrigation works and actively respond to droughts, floods and natural calamities.
- To carry out research, receive and apply advanced irrigation technology, save water, water storage, protect surface water and underground water.
- To formulate mechanisms for coordination among ministries and branches in the management and synchronization of technical infrastructure plannings.
- Consider using surface water to replace groundwater, study appropriate measures to replenish underground water.
