A sonic prospecting method has been established by the resources development institute of the Faculty of Resources Science of Kim Il Sung University, opening up another prospect for water control on the basis of scientific calculation in land administration.
The DPRK has many rivers, lakes and reservoirs and long coastlines. So only when the water is controlled well, can the flood damage be minimized and the surrounding environment improved. Moreover, the reality that the damage caused by extreme weather conditions is expanding day by day in the world requires that the country minimize natural damage to the utmost by organizing and conducting water control more scientifically according to a well thought-out plan.
The research team of the institute set themselves a goal of completing a research project on the sonic prospecting method and directed efforts towards developing an underwater ultrasonic prospecting instrument by which they can measure the depth of rivers and lakes and carry out analyses of sediment simultaneously.
In the course of intensifying the research they designed and made component parts of the underwater ultrasonic prospecting instrument to suit the actual conditions to ensure measurement accuracy and measuring speed altogether while performing measurement continuously.
On the basis of it, the research team developed a bottom materials identification program and another program to decide on the thickness of sedimentary bed layer, making it possible to control the underwater ultrasonic prospecting instrument and to collect, process and analyse data in a comprehensive way.
The sonic prospecting method proved to be advantageous in practice.
By using this method the research team could help eliminate the risk of flood damage by accurately determining the locations and distribution of stone heaps in the basin of the Taedong River and the amount of dredging.
Now the institute concentrates efforts on the research into developing new prospecting ways and methods of analysis for the survey of underwater resources.
