| | Abstract | | A lot of effort has been made to lower the amount of carbondioxide in the atmosphere. Most of the carbon is actually stored in the tree roots. So it is important to estimate the tree root biomass accurately. Conventional methods for the estimation of tree root biomass almost all include actually excavating tree roots. Although this method is obviously highly accurate, these conventional methods also have major disadvantages. Inherent to excavating the tree roots are the destructive and labour intensive nature of these methods. Ground penetrating radar (GPR) can be a solution in this case, since it provides a non-destructive and fairly easy to use method to detect the tree roots. We developed a GPR system with Miami University that works with at high accuracy positioning system. This GPR system, which we refer as 3DGPR, can measure the position with millimeter accuracy. By using this advanced GPR system, 3D images of subsurface can be obtained clearly. We tested this system for tree roots measurement, and we could demonstrate that it can be detected with this system. By using the system, in this study, we try to estimate the biomass of tree roots quantitatively by measuring the volume of the tree roots. |
