  • Modeling of the groundwater flow system in excavated areas of an abandoned mine

    Shingo Tomiyama, Toshifumi Igarashi, Carlito Baltazar Tabelin, Pawit Tangviroon, Hiroyuki Ii (Part: Corresponding author )

    Journal of Contaminant Hydrology ( ELSEVIER )  230   103617 - 103617   2020.03  [Refereed]

     View Summary

    This study evaluated the assumption that back-filled excavated areas of old mine workings can be modeled as porous media, where groundwater flow is governed by Darcy's law. The Yatani mine, located in Yamagata Prefecture, Japan, was selected for this study because several mining methods were used during its operation and detailed drawings of the excavated areas of the mine are available. The model was calibrated using combinations of hydraulic conductivities (k), with the best-matched case being selected by comparing calculated and measured AMD fluxes. Modeled AMD fluxes along the drainage tunnel (−2 L level) were consistent with measured data when the excavated areas were considered to be porous media with a specific hydraulic conductivity, and the presence of faults and permeability were taken into account. The model also successfully predicted the increasing trend of AMD flux from the shaft to adit mouth. In the numerical model, the back-filled excavated areas were assumed to behave as porous media, which was shown to be a valid assumption in this mine. The model demonstrated that back-filling the excavated areas and drainage tunnel with low permeability materials could reduce the flux of Zn in AMD by up to 61%.

  • ZN AND FE CONTAMINATION INDEX FOR RIVER USING RIVER INSECTS AND WATER PLANTS IN THE KINOKAWA RIVER CATCHMENT

    Takuma Kubohara, Hiroyuki Ii (Part: Corresponding author )

    International Journal of GEOMATE ( GEOMATE INT SOC )  19 ( 75 ) 76 - 83   2020.01  [Refereed]

     View Summary

    It has not been studied whether river insects and water plants are useful for an index of Zn and Fe contamination in the Kinokawa River catchment. Useful species as an index of Zn and Fe contamination needs a high concentration in a contaminated area, a low concentration in a non-contaminated area and a high and a wide range of their concentrations. Zn and Fe concentrations of crane fly larva around the closed Cu mine were high (88 to 420 and 1,300 to 9,300 mg/kg-dry fo rZn and Fe). Zn and Fe concentrations of bryophyte around the closed Cu mine were high (34 to 8,900 and 110 to 58,000 mg/kg-dry for Zn and Fe). Crane fly larva (81 to 420 and 110 to 9,300 mg/kg-dry for Zn and Fe) in river insects and bryophyte (24 to 8,900 and 110 to 58,000 mg/kg-dry for Zn and Fe) in water plants had high and a wide range of Zn and Fe concentration. Therefore, it was thought that crane fly larva and bryophyte were useful species for an index of Zn and Fe contamination. Zn concentrations of Pottiaceae and Fe concentrations of Brachytheciaceae around the Cu mine area (75 to 8,900 for Pottiaceae and 940 to 58,000 mg/kg-dry for Brachytheciaceae) were high. Pottiaceae (75 to 8,900 mg/kg-dry for Zn) and Brachytheciaceae (220 to 58,000 mg/kg-dry for Fe) had high and a wide range of metal concentration. Therefore, Pottiaceae for Zn and Brachytheciaceae for Fe were useful species for an index of metal contamination.

  • Relationship between rain clouds direction, topography and amount of precipitation in between the Osaka Plain and the south Ikoma Mountains, middle of Japan

    Hiroki Nishiwaki, Hiroyuki Ii (Part: Corresponding author )

    International Journal of GEOMATE ( GEOMATE INT SOC )  18 ( 65 ) 34 - 40   2020  [Refereed]

     View Summary

    The area between from the Osaka Plain to the Ikoma Mountains faces sea at only west direction and is surrounded by mountains at the other directions. Then, rain clouds can directly encounter the Ikoma Mountains only from west direction before crossing any mountains. On the other hand, rain clouds cannot encounter the Ikoma Mountains from the other directions before crossing surrounding mountains. Only when rain clouds migrated from west direction, amounts of precipitation in the Ikoma Mountains were observed to be 41 % higher than in the Osaka Plain. The altitude difference between both areas is about 400 m. When rain clouds migrated from the other directions, both amounts of precipitation for the Ikoma Mountains and the Osaka plain were almost the same. Therefore, altitude effect of amounts of precipitation for foot of mountain and top of mountain was observed only when rain clouds directly encountered the mountain before crossing the other mountains.

  • Zooplankton species richness and abiotic conditions in Thirlmere Lakes, New South Wales, Australia, with reference to water-level fluctuations

    Australian Zoologist   41 ( 1 ) 107 - 123   2020  [Refereed]

     View Summary

    Water-level fluctuations can have significant effects on lake biological communities. Thirlmere Lakes are a group of five interconnected lakes located near Sydney. Water levels in Thirlmere Lakes have fluctuated over time, but there has been a recent decline that is of significant concern. In this study, we examined over one year the species composition and richness of zooplankton (Rotifera, Cladocera and Copepoda) and abiotic conditions in Lakes Nerrigorang and Werri Berri, two of the five Thirlmere lakes, with reference to lake water level. We recorded a total of 66 taxa of zooplankton, with the first report of the rotifer Notommata saccigera from Australia, and the first report of the rotifers Keratella javana, Lecane rhytida and Rousseletia corniculata from New South Wales. There was a marked difference in abiotic conditions between the two lakes, with more variable conditions in Lake Nerrigorang. There was a significant positive correlation between zooplankton species richness and lake water level but only for Lake Nerrigorang. Although the two lakes are closely situated and thought to be potentially connected at high water levels, they show distinct ecological characters and the effect of water-level fluctuations on zooplankton species richness seems to differ between the lakes.

  • Cu, Zn and As pollution of river insect, plant and water along the metal mine tailing in Waidani area, Okayama prefecture, Japan

    Hiroyuki Ii, Shota Kumano, Akio Nishida (Part: Corresponding author )

    International Conference on Marine and Freshwater Environments, iMFE 2014     2014  [Refereed]

     View Summary

    Comparing metal concentration and distribution for river insect larva in metal contaminated and not contaminated areas, dobsonfly was clarified to be an effective indicator for metal contamination. The Waidani area was selected as metal contaminated area. Although the maximum concentration of effluent for Cu, Zn and As was 0.18, 1.5 and 0.07 mg/l, under the Japanese Effluent Standard, the maximum metal load for Cu, Zn and As reached 35, 250 and 9 kg per year, abundant of Japanese diving beetles, were only found and then specialized condition was thought to be made by the effluent. Cu, Zn and As concentrations of dobsonfly and the other river insect larva were measured in the mine areas including the Waidani mine, limestone area and not contaminated area. Dobsonfly, just one specie, Protohermes grandis, was able to cover wide concentration range for Cu (several 10 to several 1000 ppm), Zn (several 100 to several 1000 ppm) and As (0.000 to 400 ppm) and had a wide distribution. Then, its concentration was depended on metal contamination. Although the other insects had wide concentration ranges and wide distributions as well as dobsonfly, they have many kinds of species. Therefore, their concentration did not depend on metal contamination but also species.
