Nine empirical equations that estimate saturated hydraulic conductivity as a func- tion of grain size in well-graded sands with gravels having large uniformity coecients (U > 50) are evaluated by comparing their accuracy when predicting observed conduc- tivities in constant head permeability tests. According to the ndings of this thesis, in decreasing order of accuracy these equations are: USBR (Vukovic and Soro, 1992; USBR, 1978), Hazen (Hazen, 1892), Slichter (Slichter, 1898), Kozeny-Carman (Carrier, 2003), Fair and Hatch (Fair and Hatch, 1933), Terzaghi (Vukovic and Soro, 1992), Beyer (Beyer, 1966), Kruger (Vukovic and Soro, 1992), and Zunker (Zunker, 1932). These re- sults are based on multiple constant head permeability tests on two samples of granular material corresponding to well-graded sands with gravels. Using the USBR equation sat- urated hydraulic conductivities for a statistical population of 874 samples of well-graded sands with gravels forming 29 loads from a heap leaching mine in northern Chile are calculated. Results indicate that, using the USBR equation, on average the hydraulic conductivity of the leaching heaps has a two standard deviation range between 0.18 and 0.15 cm/s. Permeability tests on the actual material used in the heaps provided by the mine shows that the results presented in this thesis are consistent with actual observa- tions and represent saturated conductivities in heaps up to 3 m high under a pressures of up to 62 Kpa. In future work hydraulic conductivities can be combined with water retention curves, discharge rates, irrigation rates, porosities, and consolidation so as to evaluate the relationship between copper yields and the hydraulic conductivities of the heap

In-situ hydraulic conductivity tests have been widely used in field investigations for construction project nowadays. In this study, in order to estimate the cause of various outcomes, in-situ hydraulic testes such as Double-Ring Infiltrometer, Two-Stage Borehole Permeameter, Guelph Permeameter, and Simplified Borehole Test were conducted to compare their applicability in silty and clayey soils. In addition, numerical analysis was performed with a finite-element program, FEMWATER, to further analyze the results of the in-situ tests. The tests were simulated with FEMWATER by using the hydraulic conductivity and soil water characteristic curves obtained from laboratory experiment. The effect of anisotropy of hydraulic conductivity was also studied. Due to the difficulty of quantifying the influence of macropores and fissures in the soils on the hydraulic conductivity, the soils were assumed to be homogeneous. The study showed that the in-situ hydraulic conductivity obtained by the Guelph Permeameter was the lowest and the closest to that from the laboratory tests. On the other hand, the hydraulic conductivity measured by the Double-Ring Infiltrometer tests and Simplified Borehole tests difference were much greater. However, considering the effect of anisotropy and macropores of soil, Double-Ring Infiltrometer test could give more reliable results than Guelph Permeameter and Simplified Borehole Test.

Because of its low permeability, compacted clay is often used as liners in landfills. Under certain conditions clays may be subject to organic contamination, resulting in the change in hydraulic conductivity. This study tries to explore the dissolution of kaolinite in the presence of oxalic acid in terms of hydraulic conductivity of compacted kaolinite and bentonite-field soil mixtures. Compaction test was performed by the standard Proctor methods, and flexible-wall permeameter was used. Specimens werefirst permeated with 0.01 N CaCl2 until a stable hydraulic conductivity was observed and the oxalic acid was then introduced. Batch dissolution results show that both increasing surface protonation and decreasing surface protonation enhance thedissolution rate, and the dissolution rate was affected by the concentration of oxalic acid. Furthermore, the dissolution of kaolinite is surface controlled. Permeability test results show that in the kaolinite and bentonite-field soil mixtures systems, with the introduction of oxalic acid, hydraulic conductivities slightly decrease. The decrease is attributed to the dissolution of clods, which in turn clogged the soil pores and reduced the hydraulic conductivity. With the ratio of bentonite to field soil 12 %, the hydraulic conductivity is close to 10-8 cm/sec. In the mixtures, field soil forms the load-supporting framework and bentonite acts as a seepage barrier, and the mixture was not influenced by permeating with oxalic acid.

While groundwater flows through an unconfined aquifer due to heterogeneity, the vertical average saturated hydraulic conductivity is a function of hydraulic head. In this study, the MODFLOW model was used to calculate the relationship between hydraulic head and hydraulic conductivity in Pingtung Plain. In the model, the hydrology stress and boundary conditions were adopted study by other researches. The hydraulic conductivity was transformed with exponential function to examine the distribution properties of fuzzy membership function of the fuzzy theory. The result shows that hydraulic conductivity had fuzzy properties following the changes of groundwater head in observation wells in Pingtung Plain. This analysis indicated that the hydraulic conductivity could not be assumed as a constant value when in situ groundwater flow was simulated with numerical model. Key word : Pingtung plain, hydraulic conductivity, fuzzy theory

The property of fractured rock is highly spatial variable, and the directionality of fractures has a great influence on the hydraulic conductivity. This study presents the representative elementary volume (REV) of hydraulic conductivity of fractured rock mass. When the rock sample is smaller than the representative elementary volume (REV), the sampled hydraulic conductivity would be discrete, variable and not representative. Then use the REV to investigate the effect of the fracture orientation and Fisher constant on the hydraulic conductivity. Finally, the relationship of the connectivity is defined by the influence parameters of the fractured rock mass. Due to the research of hydraulic conductivity of fractured rock mass usually needs a large number of specimens to do the test, which is difficult to conduct due to high time-consuming and cost. In recent studies, the discrete fracture network (DFN) was widely used to simulate the fractured rock. FracMan was used to generate DFN in rock mass models and execute the systematical sampling in this study. Conventional Oda and Oda gold were adopted to estimate the hydraulic conductivity of the fractured rock mass. A series parametric study including size of rock mass model, specimen volume, dip angle, dip direction, Fisher constant κ, fracture diameter, and fracture intensity was conducted in this study. The quantized model of mean and coefficient of variance of hydraulic conductivity was established based on the results of parametric study. And consolidated the quantized result of the parameters which influence on the connectivity. Then, integrated these results to represent the quantized model of the connectivity. Finally, according to the results of the quantized model, the hydraulic conductivity and the connectivity of the fractured rock mass can be determined, which is applied to the local assessment and prediction of the flow and transmission behavior in the fractured rock mass. It has effective prevention and benefits to the engineering.

Bouwer and Rice is one of the estimation methods of slug test of obtaining the hydraulic conductivity, but it’s a synthetic value of fully drilling, do not know the hydraulic conductivity of each layers. Because of the phenomenon of the delaminated aquifer, so the Bouwer and Rice is the main method discussed in this research that purpose improving the synthetic value, because that can’t know the values of each layers. This research was based on the different circulating area of the recharge and recovery to get two formulas, use Newton-Raphson method to obtain the hydraulic conductivity values in double-layers aquifer. After verification we use the data of Dong Ju to apply to this model. According to the different ratio of transmissivity to discuss the variance, and execute the sensitivity analysis of the parameters to discuss the identifiability. Pumping test is another field test that estimating the hydraulic conductivity, it’s a large scale test that can get the hydro-geological parameters of wide range. Pumping test effected by boundary easily, according to Cooper-Jacob method, use the data of pumping test to draft the semi-log graph and obtain the hydro-geological parameters. When the pumping test encountered the boundary effect, the graph will show two different lines. If there is only one observation data, this method only knew the distance between the observation and boundary. In order to find the location of the boundary, we suggest using the data of one pumping well and two observations to determine the position of boundary, using the pumping test data of Dong Ju to discuss it.

Due to geological characteristic and high rainfall, soil erosion is generally quite serious in Taiwan. The fine soil particles were eroded easily and the gravel content in soil increased gradually. It will affect the water movement in the soil and change soil saturated hydraulic conductivity. Sieved soil sample with eight treatments, namely, 0%, 5%, 10%, 20%, 30%, 40%, 50% and 60% of volumetric content gravel in soil column were packed to measure soil saturated hydraulic conductivity using constant-head apparatus. Field experiment were measured by Guelph permeameter and cores. Relationship between repacted and in situ saturated hydraulic conductivity was developed, and saturated hydraulic conductivity of repacked soil was fitted by the concept of Kozeny-Carman formula. Experimental results indicated that, bulk density increased with increasing of soil gravel content. On the other hand, porosity decreased with increasing of soil gravel content. The change of soil saturated hydraulic conductivity may divide into three stages: ( ), when 0% < < 10% (1) ( ), when 10% < < 30% (2) ( ), when 30% < < 60% (3) where, is gravel volume content (%). Guelph permeameter and cores cannot be used in high gravel content locations. Only Guelph permeameter results were fitted with the first stage of repacked soil and the relationship function is: ( ), when 0% < <12% where, is gravel weight content (%). and is the saturated hydraulic conductivity measured by Guelph permeameter and the predicted value from equation(1).
