○Research Subject and Objectives

1.Research Objectives

 

 Securing water resources and preventing contamination of water caused by human activities in urban areas are global environmental issues in the 21st century. Heat island phenomena caused by human activities is also a big environmental problem in addition to global warming. These global environmental issues which are caused by urbanization, should be addressed strongly and prevented as population and density increases occur rapidly in urban areas.

 Most global environmental studies have long been focused on the environmental issues above ground, such as air pollution, global warming, seawater pollution, and decrease in biodiversity. Subsurface environmental issues are also important for human life in the present and future, but have been largely ignored because of the invisibility of the phenomena and difficulty of evaluations.

 Subsurface environmental problems such as subsidence due to excessive pumping and groundwater contamination, have occurred repeatedly in Asian major cities with a time lag depending on the development stage of urbanization. Therefore, we may be able to assess future scenarios if we can evaluate the relationships between subsurface environmental problems and the development stage of the city.

 

 

2.Research Content

 

 This project deals with; (1) Relationships between the development stages of the cities and subsurface environmental problems which will be assessed by socio-economic analyses and reconstructions of urban areas using historical records; (2) Serious problems in subsurface environments and changes in reliable water resources which will be studied after evaluations of groundwater flow systems and changes in groundwater storage using hydrogeochemical data and in-situ/satellite-GRACE gravity data; (3) Evaluation of accumulation of materials (contaminants) in subsurface and their transport from land to ocean including groundwater pathways using chemical analyses of subsurface water, sediments and tracers; and (4) Subsurface thermal contamination due to the “heat island” effect in urban areas by reconstruction of surface temperature history and urban meteorological analyses.

 Tokyo, Osaka, Bangkok, and Jakarta are targeted as main study cities, and Taipei, Manila and Seoul are selected as secondary study cities, depending on the four sub-themes. The project will focus on the urban subsurface environments however, we will treat the problems on a basin scale, because subsurface water, heat, and material transports are interconnected on this scale. We will assess the relationships between subsurface environmental changes and human activities during the past 100 years.

○Progress and Results in 2017

 Outline of results

(1) Field surveys on subsurface environment in targeted cities have been made, and monitoring of subsurface environments at 7 cities (Bangkok, Jakarta, Manila, Seoul, Taipei, Tokyo and Osaka) has been going on.

(2) Assessments of natural and social data in each city, and a database based on GIS have been made. Land cover/use maps based on GIS with 0.5 km mesh have been made at three development stages (1930’s, 1970’s, and 2000’s) of seven cities.

(3) International Symposium, HydroChange2008, has been organized by RIHN, with IAHS and GWSP, and the book “From Headwater to the Ocean” has been published by CRC press (679 pp).

(4) Studies on cross cutting theme such as religion-groundwater relationships have been made in Bangkok and Jakarta. The relationships between groundwater discharge and elevation of the religious facilities and soil have been investigated.

(5) Interim results of the project have been published by special issue of STOTEN (Science of the Total Environment, Elsevier) including one overview and 15 original papers.

○Future Themes

(1) New approaches on the relationship between law/institution and groundwater (private water) /surface water (public water) have been started. Integration of the chronology of the document and database will be made.

(2) New working groups on integrated model and indicators will integrate the status of social economics, water resources, environmental loads, and policy on subsurface environment.

(3) Land cover/use data based on GIS at three ages (1930’s, 1970’s and 2000’s) in 7 cities will be used for evaluating groundwater recharge rate, thermal storage in aquifer, and subsurface contamination.
