Abstract:

Sand and gravel in River bed are common construction materials indispensable in urban development, infrastructure, and wharves ... due to the shortage of supply, throughout the rivers in Vietnam. Determination of the volume of regenerated sand annually or according to a certain cycle can use the MIKE 21 FM (HF + ST) hydraulic model given by Danish Institute of Water and Environmental Engineering. Calculation results of the experimental model for the river section across the Phuc Tho district, Hanoi city show that the Vinh Khang sand mine was more simulated during period from 2010 to 2019 and still lower regenaration in the comming years. These results will be significal basis for Mining lisener to orient mine development, adjust capacity and limit exploitation in sediment-deficient areas, avoid locations where there are high erosion trend. The simulation results from the model also are scientific basis for the state management to make master plane, locate sand and gravel material potential areas. But in completing a model it takes time, synthesized data of fields such as geology, hydrometeorology, surveying, geophysics,… it is essential that the functional ministries would make coordinate to bring benefits for organizations and individuals to use lifting data to get high reliability for model results.
