• Laboratory Flushing Tests of Dissolved Contaminants in Heterogeneous Porous Media with Low-Conductivity Zones

  Tomoki Kurasawa, Yoshitaro Takahashi, Mariko Suzuki, Kazuya Inoue

  Abstract The retention of contaminants within low-conductivity regions such as clay lenses and aquitards can greatly affect groundwater remediation processes. The aim of this study was to experimentally investigate the effects of the geometry of low-conductivity zones, conductivity contrast, and flow regime on solute flushing. We conducted a series of flushing tests in cylindrical models containing a cylindrical low-conductivity zone (i.e., low-K zone) embedded in a highly conductive medium (i.e., high-K zone). Seven models comprising four high-conductivity-contrast (SL, SS, LL, and LS), one medium-contrast (LLM), one low-contrast (LLL), and one homogeneous (H) models were considered. Experiments were conducted at two flow rates (Q = 0.6 and 26 cm³/min) for each heterogeneous model (SL, SS, LL, LS, LLM, and LLL) to compare the flushing processes in different flow regimes. First, we verified the validity of our experiments by comparing the results of the H model from an analytical solution with our experiment. The results of the high-contrast models showed that for a diffusion-dominated regime (Q = 0.6 cm³/min), the pore volume injected (PVI) required to flush out solute mass was much smaller than that in an advection-dominated regime (Q = 26 cm³/min). To evaluate the pore volumes required to flush out solutes for the four high-contrast models, we introduced a parameter P_0.01, which is defined as the PVI needed for the relative concentration to become 0.01 at the middle of the low-K zone. P_0.01 decreases with increasing the specific surface area of the low-K zone for diffusion-dominated regimes, while it increases with increasing the length of the low-K zone for advection-dominated regimes. We also determined the importance of the effect of K contrast on solute retention by comparing the results of three different models of K contrast (LL, LLM, and LLL).

• A stepwise route to domesticate rice by controlling seed shattering and panicle shape

  Asian rice ( Oryza sativa L.) is consumed by more than half of the world's population. Despite its global importance, the process of early rice domestication remains unclear. During domestication, wild rice ( Oryza rufipogon Griff.) acquired non-seed-shattering behavior, allowing humans to increase grain yield. Previous studies argued that a reduction in seed shattering triggered by the sh4 mutation led to increased yield during rice domestication, but our experiments using wild introgression lines show that the domesticated sh4 allele alone is insufficient for shattering loss in O . rufipogon . The interruption of abscission layer formation requires both sh4 and qSH3 mutations, demonstrating that the selection of shattering loss in wild rice was not as simple as previously suggested. Here we identified a causal single-nucleotide polymorphism at qSH3 within the seed-shattering gene OsSh1 , which is conserved in indica and japonica subspecies but absent in the circum -aus group of rice. Through harvest experiments, we further demonstrated that seed shattering alone did not significantly impact yield; rather, yield increases were observed with closed panicle formation controlled by SPR3 and further augmented by nonshattering, conferred by integration of sh4 and qSH3 alleles. Complementary manipulation of panicle shape and seed shattering results in a mechanically stable panicle structure. We propose a stepwise route for the earliest phase of rice domestication, wherein selection of visible SPR3 -controlled closed panicle morphology was instrumental in the sequential recruitment of sh4 and qSH3 , which together led to the loss of shattering.

• RELATIONSHIP BETWEEN SPATIAL DISTRIBUTION CHARACTERISTIC OF HYDRAULIC CONDUCTIVITY AND SOLUTE DISPERSION FOR UPSCALED STRATIFIED POROUS FORMATIONS

  KURASAWA Tomoki, SUZUKI Mariko, INOUE Kazuya

  The objective of this study is to investigate the effect of upscaling on spatial distribution characteristic of hydraulic conductivity and solute dispersion for a stratified porous model. A geostatistical analysis allowed quantification of spatial characteristic for the upscaled models. As a result, the smoothing of spatial distribution due to upscaling reduced the heterogeneity, whereas the spatial correlation scale was preserved. In order to identify the relationship between the degrees of solute dispersion and upscaling, a combined experimental and numerical investigation is conducted. The data from the experiment are utilized to validate a numerical model that is then used to estimate the strength of the dispersion processes (i.e., longitudinal and transverse macrodispersivities) in the upscaled models. It is shown that upscaling does not affect the transverse macrodispersivity, while the longitudinal macrodispersivity is underestimated due to the decrease of heterogeneity during the upscaling process. Moreover, the result suggested that the mass transfer between layers be altered by increase in the layer thickness due to upscaling, leading to the plume spreading in the longitudinal direction.

• Physical and Mechanical Properties of Dehydrated Cake Discharged from Crushed Stone Quarry

  SUZUKI Mariko, SAITO Hirohito, MATSUKA Takeju, MATSUSHITA Haruhiko, INOUE Kazuya

  Most of dehydrated cake which was generated by turbid water treatment of the process for making crushed stone and crushed sand is subjected to landfill disposal. The effective use of dehydrated cake discharged from crushed stone quarry is required to relieve the tightness of the residual capacities of disposal sites and to secure limited natural resources. In this study, a dehydrated cake discharged from crushed stone quarry with excellent caking properties was examined to see if it can be used for soil materials, such as impermeable materials. In addition, physical and mechanical tests were conducted on the dehydrated cake, and then its properties were compared with those of commonly used cohesive soils. It was found that the dehydrated cake had significantly different properties from those of general cohesive soils, and it also did not match the mechanical properties of general compacted soils. Thus, it was concluded that the dehydrated cake cannot be handled based on the commonly used soil standards. In addition, it was found that reducing the water content and adjusting the particle size are effective in increasing the strength of dehydrated cake and that reducing the water content is particularly effective.

• Effects of upscaling of physically heterogeneous porous media on solute transport macrodispersion phenomena

  Tomoki KURASAWA, Kazuya INOUE

  Intermediate-scale laboratory solute transport experiments were conducted in physically heterogeneous and homogeneous porous formations to investigate the impacts of upscaling of hydraulic conductivity on the behavior of solute macrodispersion. Solute transport in porous media based on geostatistics was visualized and solute macrodispersion parameters were quantified by using dye tracer imaging technique. The results showed the longitudinal and transverse macrodispersivity estimates decrease with the increase of the degree of upscaling due to a lower heterogeneity corresponding to the upscaling. The macrodispersivity estimates were almost constant in heterogeneous porous formations having the cell size of less than 6 cm, which is the correlation length of non-upscaled porous formation, whereas for large cell sizes macrodispersivity estimates depended strongly on the length of the cell. As the degree of upscaling increased, the horizontal distance between forward and backward edges of the solute plume decreased.

• Spatial and Temporal Moment Approaches to Quantify Laboratory-Scale Macrodispersion in Stratified Porous Formations

  Inoue Kazuya, Kurasawa Tomoki, Tanaka Tsutomu

  In this study, intermediate scale dye tracer experiments were conducted in a 1m length, 1m height and 0.03m thickness sandbox to quantify macrodispersion phenomena in stratified porous formations and to elucidate the effect of the layering on the degree of macrodispersion. Spatial and temporal moment approaches based on a snapshot of tracer distribution and NaCl concentration at a point, respectively, were applied to identify the macrodispersivities in longitudinal and lateral directions. The experimental results indicated that the longitudinal macrodispersivity depends on the travel distance of solute and the degree of heterogeneity in stratified formations with two or four layers, while the transverse macrodispersivity decreases with the increase of travel distance and depends on the magnitude of the initial solute distribution. A difference between longitudinal macrodispersivity estimates using spatio-temporal moments was also clarified.

• Quantification of solute macrodispersion phenomena and local heterogeneity using intermediate-scale solute transport experiments in heterogeneous porous formations

  INOUE KAZUYA, FUJIWARA TAKAYUKI, KURASAWA TOMOKI, TANAKA TSUTOMU

  Intermediate-scale laboratory solute transport experiments were conducted in heterogeneous porous formations comprised by 144 sand cells. Visualization of dye solute was applied to transitional estimates in longitudinal and transverse macrodispersivities caused by the presence of heterogeneities. Results showed that a distinct transition of the longitudinal macrodispersivity was confirmed due to the local heterogeneity while a continuous decrease in transverse dispersivity was shown despite of the initial source location. Quantification methodologies were proposed to achieve the ensemble estimation of five distinct transitions of macrodispersivities and the local heterogeneity quantification based on solute pathways, leading to appropriate outcomes relevant to not only the variation and distribution of estimates but the degree of the longitudinal macrodispersivity.

  SAWADA YUTAKA, 園田 悠介, 小野 耕平, INOUE KAZUYA, 毛利 栄征, 有吉 充, KAWABATA TOSHINORI

  近年，耐用年数を迎える農業用管路の増加に伴い，非開削での施工が可能な管路更生工法の採用が進展している。しかしながら，更生管の力学挙動は未解明で，設計手法も確立されていない現状にある。更生工法では，老朽化した既設管を撤去せずに管路を更新するため，半永久的に更生管外周に既設管が残存する。本研究では，既設管損傷レベルと荷重条件を変化させた土中埋設実験を実施し，既設管が更生管力学挙動に与える影響について検討した。その結果，既設管損傷レベルの進行に伴い，更生管のたわみが増大することが明らかになった。また，損傷状態によっては，既設管と更生管が点接触することで，局所的に卓越したひずみが発生することがわかった。さらに，地表面偏心荷重の場合，ひずみが卓越する箇所が損傷レベルにより異なることが明らかになった。

• Influences of Damage Levels of Outer Aging Pipes on Mechanical Behavior of Rehabilitated Pipes

  SAWADA Yutaka, SONODA Yusuke, ONO Kohei, INOUE Kazuya, MOHRI Yoshiyuki, ARIYOSHI Mitsuru, KAWABATA Toshinori

  Recently, trenchless rehabilitation methods for aging irrigation pipes are often used. In this method, a new pipe is inserted into an aging pipe. Therefore, the rehabilitated pipeline consists of the outer aging pipe and the inner rehabilitated pipe. However, the mechanical influences of the damaged outer pipes on the inner rehabilitated pipes are not clear. In the present study, in order to reveal the influences, model experiments were conducted under the different damage levels of the aging pipe and loading positions. Experimental results indicate that the deflection of the rehabilitated pipe increases according to the damage level of the aging pipe. In addition, the strain concentration occurs at the top and the bottom of the rehabilitated pipe due to the point contact of the edge of the aging pipe. It is also found that the deflection and the strain distribution of the rehabilitated pipe under the eccentric load are significantly affected by the damage level of the aging pipe.

The former is an element test which is not allowed to move soil particles under different conditions. The latter is a model test which is not allowed to move soil particles under different conditions. The results of the former test concluded that there is no difference between specimen reinforced with Geogrid and specimen unreinforced Geogrid when their compaction degrees were enough. The results of the latter test concluded that Geogrid restricts the movement of soil particles.

  近年,様々な有害物質による土壌・地下水汚染が報告されており,人の健康や生態系への影響が懸念されている.そのため,多くの研究者や研究機関によりリスクに関する研究が進められているが,環境リスク評価手法が確立されていないのが現状である.地盤内において汚染物質は物質自体の特性や地盤特性に応じて様々な挙動を示し,地下水への溶出形態も多様である.本研究では地下水汚染の環境リスク評価に焦点を当て,汚染物質の移動解析で用いるモデルパラメータが評価結果に及ぼす影響を考察する.解析解を用いることで仮想地盤における物質移行問題を単純化し,パラメータの差異による濃度変化やそれを用いたリスク評価に関して検討する.

• Mass Transport Analysis with Nitrogen Species Transformation Model in Soil

  INOUE Kazuya, KOBAYASHI Akira, AOYAMA Shigeyasu

  An one-dimensional finite element mass transport model with nitrogen species transformation was developed to predict the transport of nitrate-nitrogen (NO₃-N), nitrite-nitrogen (NO₂-N), and ammoniumnitrogen (NH₄-N) in porous media. Field experiments using sulfate ammonium wereperformed and temporal and spatial distributions of NO₃-N concentration and volumetric water content were measured. The numbers of nitrifers and denitrifers, and pH values were also measured. The rate of aquifer recharge and rate coefficients of the transformation were calibrated to fit the measured distributions of water content and NO₃-N concentration at 28th day of experiments. The validity of this model was examined and confirmed by comparing the results of numerical analysis under the calibrated values with measured data at 42nd day of experiments. It was found that there is a good correlation between the number of microbe and rate coefficients, which greatly affect the prediction results. The variation of the NO₃-N concentration is able to be predicted through this model in the experimental site when appropriate rate coefficients are used based on environmental conditions, which have the effect on microbial activity.

  既設開水路内に管路を敷設する開水路内配管工法の確立を目標に，老朽化した開水路内に設置された管路屈曲部を対象にスラスト力を模擬した水平力を負荷する実験を実施してきた．令和2年度に実施した模型実験では，載荷中に模型管が軸方向に回転し，正確に水平抵抗力が計測できていないことが明らかとなった．そこで，令和3年度には，載荷装置を改良し，同条件での実験を実施した．概ね前年度と同様の結論を得たが，水路底板と水路壁が固定された実験条件では，管と開水路模型が一体となり挙動する様子が観察され，前年度と異なる新たな知見を得た．また，管と水路壁の間の距離を変えた条件での実験ケースについて，より詳細な検討を行い，本研究で実施された埋設条件では，距離と抵抗力が概ね線形で近似できることを示すとともに，画像解析を通して，管および水路壁周辺地盤の変形挙動ならびに抵抗力発揮メカニズムを解明した．さらに，既設開水路内に2本の管路が敷設される二条配管時の力学挙動を解明するため，2本の模型管に定荷重を負荷した載荷実験に着手し，現在までに基本ケースの実験を終了した． 上記のスラスト力を受ける管路屈曲部の力学挙動の検討に加え，管底側部の応力集中の緩和を目的としたEPS基礎を提案し，その有効性についても実験的に検証してきた．令和2年度に実施した模型実験では，模型管の外径が165mmと小さく，一部のEPS基礎では，応力集中を抑制する効果が確認できなかった．そこで令和3年度には，模型管の外径を313mmとし，地盤の相対密度を前年度の30%から60%に変更することで，より実際に近い埋設条件を再現した．実験結果よりEPS基礎を用いた全てのケースで管底側部の応力集中を抑制する効果が確認された．


• 異常輸送理論と群知能を融合した「地下ダム管理モデル」の構築と実装

  本研究は，地下ダム湖にて肥料成分が移動，濃縮，流出する力学現象に関する科学的洞察と人工知能の一分野である群知能・機械学習により，新たな「地下ダム管理モデル」の構築と実装を目的としている．本年度は，3つのテーマに対して実験的・数値解析的に取り組んだ． 1つ目は，実フィールドを対象として，物理的・経済的に制約の強い実フィールドのパラメータ推定の効率化を図るべく，単独の観測孔を利用した単孔式希釈試験に基づく簡易推定手法を開発した．対象フィールドは，喜界島の琉球石灰岩地域である．単孔式希釈試験ではNaClをトレーサとして，観測孔内部の地下水域へ均一に投入し，複数の深度にてNaCl濃度を時系列計測した．観測濃度データを理論解と適合して，ダルシー流速，地下水流速を簡便かつ迅速に推定した．実験の結果，当該地域では帯水層の深部ほど希釈スピードが低減することが確認され，深度とともに透水係数は小さくなることを示唆した．また，周辺の地下水の動水勾配と現場透水試験の結果から得られた水平地下水流速と比較すると，単孔式希釈試験から得られた流速の推定値は概ね一致し，提案手法による地下水流速の推定は一定の信頼性があることを結論付けた．2つ目は，喜界地下ダム流域の地下水流動にかかわる三次元有限要素モデルを再構築した．群知能を用いて地下ダム帯水層の透水係数分布を効率よく同定するとともに，モデル拡張したランダムウォーク粒子追跡解析により各集水井の硝酸態窒素の取り込み状況について数値解析した．3つ目は，模型実験にて喜界第2地下ダム湖の移流分散現象を定量化した．喜界第2地下ダム湖における溶質輸送経路は塩水くさびの影響を受けて上昇し，北堤帯水層の高透水層は溶質分布の拡大に寄与する．また，地下水面付近の移流分散現象は北堤と南堤で差異はなく，ダム壁建造後は，北堤より南堤の方が観測濃度は高くなる可能性があることを示した．

  To achieve the method and procedure of performance based design for agricultural irrigation facilities, detailed performance of both material and structures are necessary. Behavior of important materials such as concrete, soil and rock materials are investigated with experimental and analytical method. For concrete material, the fracture energy, which is an important parameter for numerical fracture analyses, is measured by newly developed experimental method. The method is proved to be applicable to dam concrete which contains coarse aggregate of large size. Magnitude and behavior of shrinkage in dam concrete are also investigated through experiments. For concrete structures, the depth of cracking are measured using ultrasonic measures and its validity and accuracy are studied. Soil is another important material for embankment and basement, but piping and other kind of seepage fracture leads to catastrophic destruction. Using stochastic, numerical, and experimental methods, the danger of seepage fractures are evaluated. The obtained result will be used to determine the design standard of embankments to prevent seepage fractures. For rock materials, the effect of weathering is investigated. For artificially weathered rock materials, the strength and deformation characteristics are measured. By these experiments, the conditions which lead to serious weathering are also examined.
