1.Research on geothermal heat utilization records and database compilation
In this fiscal year, we carried out literature investigation to collect existing case studies on GSHP utilization as well as groundwater information, and we compiled/synthesized those data for database development.
We collected the GSHP utilization about 116 examples, and the number of effective thermal conductivity data obtained by thermal response test (TRT) we collected was 89 examples. In addition, we collected groundwater level of Kanto District mainly and compiled it based on a priority of the model construction.
2.Construction of the 3D geological structured model
In this fiscal year, we focused on Kanto region and built 3D geological feature structured model including 23 wards of Tokyo, Kanagawa and Saitama. The horizontal resolution is range of 50 to250m and vertical resolution is 1m. The model was constructed based on boring data. However, in where have limited boring data, geological maps and cross sections were used.
On the other hand, the quantity of data embedded in the model exceeded 100 million, and we found that such huge amount of data was difficult to handle (data extraction and analysis) using existing software tools we have used so far. We are going to develop the data inspection tool which is available for processing such big data in upcoming 2015 fiscal year.
3.Development of the multi-scaled integrated watershed models for national water and thermal circulation
For the Kanto-Tohoku region with the area of 200,000km2, we have started numerical modeling and computation that simulate surface and subsurface-coupled water and thermal circulation behavior. Using the collected data, we have started to develop the 3D numerical model for the Kanto-Tohoku regional area. The horizontal spatial resolution is 500m and total number of grid-blocks is 27,500,000. We developed a novel workflow for more efficient modeling task with the emphasis on efficient improving and/or updating the existing models according to the update of field information. Using the developed model, we have demonstrated numerical simulation by applying the surface and subsurface-coupled watershed modeling technologies with computer code GETFLOWS.
4.Technology development for evaluating GSHP potential and integrated informative system
We have started to develop the data processing procedure that enables us to map comprehensive GSHP potential data in different depth and to offer evaluated results to users quickly and efficiently. The target users of the developed information system are local government and developers/designers of GSHP system.
