Abstract:

The infiltration capacity is a decisive factor to ensure the effective operation of groundwater reservoir. This study analysis the infiltration capacity variation and its factors based on the data of infiltration test in Hutuo River Groundwater Reservoir. The results show that, there is a high infiltration rate in the alternative field, the infiltration rate is 3m/d, and decreased by 50% as 1.4m/d 6 days later; the contrast of soil permeability, vertical permeable rate of aerial zone, permeability of saturation zone between pre-test and post-test show that, the vertical permeable rate of aerial zone and permeability of saturation zone vary little, the descend of soil permeability is the main factor of the infiltration capacity decay.

Abstract:

Thinning is a crucial practice in the forest ecosystem management. The soil infiltration rate and water storage capacity of pine-oak mixed forest under three different thinning intensity treatments (15%, 30%, and 60%) were studied in Qinling Mountains of China. The thinning operations had a significant influence on soil infiltration rate and water storage capacity. The soil infiltration rate and water storage capacity in different thinning treatments followed the order of control (nonthinning): <60%, <15%, and <30%. It demonstrated that thinning operation with 30% intensity can substantially improve soil infiltration rate and water storage capacity of pine-oak mixed forest in Qinling Mountains. The soil initial infiltration rate, stable infiltration rate, and average infiltration rate in thinning 30% treatment were significantly increased by 21.1%, 104.6%, and 60.9%, compared with the control. The soil maximal water storage capacity and noncapillary water storage capacity in thinning 30% treatment were significantly improved by 20.1% and 34.3% in contrast to the control. The soil infiltration rate and water storage capacity were significantly higher in the surface layer (0~20 cm) than in the deep layers (20~40 cm and 40~60 cm). We found that the soil property was closely related to soil infiltration rate and water storage capacity.

Abstract:

The infiltration of rainfall into a slope surface may affect slope stability; thus, it is important to understand the amount of rainfall infiltration (hereafter referred to as the “infiltration capacity”) for a slope surface layer when evaluating slope stability. This research focuses on slope gradient, a factor affecting the infiltration capacity, and performs two types of water-spraying experiments using pit sand under the same conditions but with different slope gradients. In the first experiment, the surface flow rate and soil loss were measured using an earth-tank model with a horizontal distance of 0.5 m, depth of 0.1 m, and width of 0.2 m to form slope gradients of 2°, 20°, and 40° to clarify the effect of slope gradient on the infiltration capacity. In the second experiment, a water-spraying experiment that closely simulated natural rainfall was performed at a large-scale rainfall facility owned by the National Research Institute for Earth Science and Disaster Resilience (NIED), Japan. This experiment used an earth-tank model with a horizontal distance of 1.21 m, depth of 0.5 m, and width of 0.5 m to form slope gradients of 2°, 10°, 20°, 30°, and 40° with the aim of proposing a quantitative evaluation method for the relationship between the slope gradient and infiltration capacity. The results showed that the soil loss and infiltration capacity increased as the slope gradient increased in the case of the pit sand used in the experiments. This was confirmed to be due to the fact that an increased gradient allowed grains with diameters of <50 μm in the slope surface layer to flow out easily, thereby increasing the infiltration capacity. In addition, the relationship between the rainfall intensity and infiltration capacity revealed that the infiltration capacity varied depending on the rainfall intensity and slope gradient, which is unlike the relationship for constant values such as the permeability coefficient. Moreover, the research findings indicated a strong, positive linear relationship (R2 = 0.98) between the slope gradient and fitting factor Ic. Therefore, the relationship between rainfall intensity and the infiltration capacity could be expressed using the fitting factor Ic. This suggests the possibility of quantitatively evaluating the relationships between rainfall intensity, the infiltration slope gradient, and the infiltration capacity.

Abstract:

Analyzing the Influence of Rain Frequency Infiltration Rate and Infiltration Capacity in Common Soil Type (Laboratory Testing Study With Rainfall Simulator). Infiltration is the flow of water into the ground through the soil surface. This process is a very important part of the hydrological cycle and in the process of transferring rain into the flow of water in the soil before reaching the river. Infiltration (infiltration rate and capacity) is influenced by various variables, including soil type, slope inclination, density and type of vegetation, soil moisture content, and rainfall intensity. This study aims to determine the effect of rainfall frequency on the infiltration rate and infiltration capacity on common soil types. This research is a type of laboratory experimental research, using rainfall simulator tool. The soil used in this study is common soil type. Furthermore, artificial rain was provided with intensity I5, I15, and I25 and performed infiltration rate reading on the Drain Rainfall Simulator. The rate and capacity of infiltration in common soils increase proportionally to the increased intensity of rainfall, the higher the intensity of rainfall the higher the infiltration occurring at the same level of rain frequency. The rate and capacity of infiltration in common soils decrease proportionally to the increasing frequency of rain, the more the frequency of rain the smaller the infiltration occurring at the same level of rainfall intensity

Abstract:

This research used a newly developed, full-scale infiltration testing (FSIT) procedure to determine the saturated surface infiltration rate of 16 existing permeable pavement installations in the Netherlands that have been in service for a number of years. Newly installed permeable pavements in the Netherlands must demonstrate a minimum infiltration capacity of 194 mm/h (540 L/s/ha). Only four of the 16 pavements tested in this study had an infiltration capacity higher than 194 mm/h. Most previous research has focused on unsaturated infiltration rates. However, the results of this study show that the difference in infiltration capacity between saturated and unsaturated can differ by up to 300%. If the unsaturated infiltration capacity is used as design input for computer models, the infiltration capacity may be significantly overestimated. The study demonstrated that the FSIT method is a reliable and accurate way to measure surface infiltration rates of permeable pavements. However, it is recommended that a minimum of three different FSIT tests should be undertaken at the same pavement location, and that the results should be averaged, to ensure appropriate infiltration rates are observed, recorded, and used in design. The results of this study should help stormwater managers with the planning, testing, and scheduling of maintenance requirements for permeable pavements with more confidence so that they will continue to perform satisfactorily over their intended design life.

Abstract:

Increased urbanization causes pervious greenfields to be converted to impervious areas increasing stormwater runoff. Most of the urban floods occur because existing drainage systems are unable to handle peak flows during rainfall events. During a storm event, flood runoff will carry contaminants to receiving waters such as rivers and creeks. Engineers and scientists have combined their knowledge to introduce innovative thinking to manage the quality of urban runoff and harvest stormwater for productive purposes. The introduction of pervious pavements addresses all the principles in Water Sensitive Urban Design. A pervious pavement is a load bearing pavement structure that is permeable to water. The pervious layer sits on the top of a reservoir storage layer. Pervious pavements reduce the flood peak as well as improve the quality of stormwater at source before it is transported to receiving waters or reused productively. To be accepted as a viable solution, understanding of the influence of design parameters on the infiltration rate (both from the bedding and the sub-base) as well as strength of the pavement requires to be established. The design of a particular pavement will need to be customized for different properties of sub layer materials present in different sites. In addition, the designs will have to meet local government stormwater discharge standards. The design of drainage systems underneath pervious pavements will need to be based on the permeability of the whole pervious system. The objectives of the research project are to: Understand the factors influencing infiltration capacities and percolation rates through the pervious surface as well as the whole pavement structure including the bedding and the sub-base using a laboratory experimental setup. Obtain relationships between rainfall intensity, infiltration rate and runoff quantity based on the sub-grade material using a computational model to assist the design of pervious pavements. A laboratory scale pavement was constructed to develop relationships between the surface runoff and the infiltration volume from a pervious pavement with an Eco-Pavement surface. 2 to 5mm crushed gravel and 5 to 20mm open graded gravel were chosen as the bedding and sub-base material. Initial tests such as dry and wet density, crushing values, hydraulic conductivity, California Bearing Ratio tests for aggregate material were conducted before designing and constructing the pavement model. A rainfall simulator with evenly spaced 24 sprays was set up above the pervious pavement surface. The thesis presents design aspects of the laboratory scale pavement and the tests carried out in designing the pavement and the experimental procedure. The Green and Ampt model parameters to calculate infiltration were obtained from the laboratory test results from aggregate properties. Runoff results obtained from rainfall simulator tests were compared with the Green and Ampt infiltration model results to demonstrate that the Green and Ampt parameters could be successfully calculated from aggregate properties. The final infiltration rate and the cumulative infiltration volume of water were independent of the rainfall intensity once the surface is saturated. The model parameters were shown to be insensitive to the final infiltration capacity and to the total amount of infiltrated water. The Green and Ampt infiltration parameters are the most important parameters in designing pervious pavements using the PCSWMMPP model. The PCSWMMPP model is a Canadian model built specially for designing pervious pavements. This is independent of the type of sub-grade (sand or clay) determining whether the water is diverted to the urban drainage system (clay sub-grade) or deep percolation into the groundwater system (sand sub-grade). The percolation parameter in Darcy's law is important only if the infiltrated water recharges the groundwater. However, this parameter is also insensitive to the final discharge through the subgrade to the groundwater. The study concludes by presenting the design characteristics influencing runoff from a pervious pavement depending on the rainfall intensity, pavement structure and sub-grade material and a step-by step actions to follow in the design.

Abstract:

Title: The Esthetic Outcome and the Infiltration Capacity of Three Resin Composite Sealers Compared to ICON (DMG, America). Objective: The aim of these studies, including a randomized control in-vitro study and a survey study was to answer the following question: In treating initial caries lesions, is the esthetic outcome and the infiltration capacity of the three resin composite sealers; BisCover LV (Bisco Dental), Optiguard (Kerr), PermaSeal (Ultradent) similar to that of the gold standard ICON (DMG, America) resin infiltrant. Methods: A sample of 75 extracted human permanent molars were painted with an acid resistant nail varnish (Revlon, USA) to protect the tooth surface from demineralization leaving only two panels of 1x7 mm of exposed enamel on the buccal and the lingual surfaces of each tooth to be demineralized. Samples were immersed in an acidic gel (500g of Fisher G-8 Gelatin, 275 Bloom, 0.1% thymol, lactic acid, pH 4.30) for a period of 3 months to create artificial initial caries lesions. Seventy-five specimens were randomly assigned to 5 groups: I: ICON (DMG, America), B: BisCover LV (Bisco Dental), O: Optiguard (Kerr), P: PermaSeal (Ultradent) and C: control group. Specimens were hemi sectioned yielding two halves, each with a panel of 1x7 mm of initial caries lesion. One side was used to assess the esthetic following the caries lesion resin infiltration with ICON, BisCover LV, Optiguard and PermaSeal applied according to ICON manufacturer instructions. The control group (C) did not receive any treatment and was only included in the esthetic part of this study. Preoperative and postoperative photographs were taken. Two sets of photographs were taken for the control group. The preoperative, postoperative and control group photographs were installed in a PowerPoint presentation and placed side by side on a black background. A total of 17 operative faculties and residents at the department of operative dentistry at the University of Iowa (UI) participated in the survey. The esthetic improvement was assessed based on a 100-mm visual analogue scale (VAS). A value between 0 and 20 indicated slight esthetic improvement. A value between 20 and 40 indicated mild esthetic improvement. A value between 40 and 60 indicated moderate esthetic improvement. A value between 60 and 80 indicated high esthetic improvement. A value between 80 and 100 indicated outstanding esthetic improvement. A value of 100 indicated full esthetic recovery. Each subject was asked to look at the preoperative and postoperative photographs of a specimen in each slide and place a line on the respective VAS according to her/his opinion of esthetic improvement. The survey was conducted twice in two different sessions to evaluate the inter-rater and intra-rater reliability. For lesions on the opposite side, the resins: ICON, BisCover™LV, Optiguard and PermaSeal were applied according to the indirect dual fluorescence technique protocol using the red ﬂuorophore rhodamine B isothiocyanate (RITC 0.1%; Sigma Aldrich, Steinheim, Germany) and the green sodium ﬂuorescein (NaFl; Sigma Aldrich). Specimens were sectioned in a mesio-distal direction yielding thin sections of 200 μm and were visualized under the Confocal Laser Scanning Microscope (CLSM, Leica Microsystems, Buffalo Grove, IL.) to assess the infiltration depth percentage (ID%) and the infiltration area percentage (IA%) following the application of the different resins. Statistical analysis: The effect of treatment type on ID% and IA% was evaluated using the one-way ANOVA. The effect of treatment type on esthetic improvement measures represented by VAS scores was evaluated using the non-parametric analogue of the one-way ANOVA; Kruskal-Wallis test. All pairwise comparisons were performed using the Tukey method with an overall 0.05 level of significance. Spearman rank correlations were used to assess the relationship between esthetic improvement measures and infiltration measures. Validity of assumptions related to normality and variance homogeneity were assessed using the Shapiro-Wilk and Brown-Forsythe tests, respectively. The intra-class correlation and associated 95% confidence interval reflecting the reproducibility of the mean VAS scores and the reliability among the evaluators were obtained using the method of Shrout and Fleiss. The Wilcoxon Signed Rank procedure was used to evaluate differences between sessions for individual evaluators. The paired student’s t-test was used to detect any systematic differences between the mean VAS scores at session 1 and 2. Bonferroni adjustment for multiple testing was made for the 17 tests associated with individual raters, using an overall 0.05 level of significance. Results: the mean IA% values were significantly higher in the ICON group compared to the other three treatment groups. Optibond and Permaseal groups resulted in intermediate values that did not differ significantly from each other. Biscover group yielded the lowest mean values and were significantly lower than that of the other three treatment groups. The results of the ID% values were consistent with the results of the IA% values. the mean ID% values were significantly higher in the ICON group compared to the other three treatment groups. Optibond and Permaseal groups resulted in intermediate values that did not differ significantly from each other. Biscover group yielded the lowest mean values and were significantly lower than that of the other three treatment groups. The distribution of esthetic improvement outcomes represented by the average VAS scores for session 1 (AVGVAS1), average VAS scores for session 2 (AVGVAS2), and the combined average VAS scores (AVERAGED_VAS) for each sample obtained from the two sessions were all significantly lower in the control group than in the other four treatment groups. Biscover yielded intermediate average VAS values. ICON, Optiguard and Permaseal yielded significantly greater average VAS values than both the control and Biscover groups and were not significantly different from each other. According to the Spearman rank correlations which was used to assess the relationships between the esthetic improvement measures; AVGVAS1, AVGVAS2 and AVERAGED_VAS for each sample and the two measures of infiltration; the IA% and the ID%, all results were highly significant (p<0.0001) and indicative of a moderately large positive correlation between each of the infiltration measures and the three esthetic improvement measures. The Spearman coefficients for the six relationships evaluated were quite similar, ranging from about 0.523 to 0.548. Conclusion: The resin composite sealers BisCover LV, Optiguard and Permaseal can infiltrate artificial initial caries lesions. The esthetic outcome of artificial initial caries lesion following resin infiltration with Optiguard and Permaseal was similar to ICON and thus might be adequately used in caries resin infiltration. BisCover LV showed the least esthetic improvement and thus might not be indicated for the esthetic management of initial caries lesions but might be used for caries prevention purposes. The esthetic improvement is correlated to the resin infiltration depth to a certain extent after which the esthetic outcome will not be visually impacted.

Abstract:

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico
A antropizaÃÃo de florestas nativas causa desequilÃbrios de ecossistemas, modificando propriedades fÃsicas, quÃmicas e biolÃgicas do solo. Dentre os efeitos encontra-se a reduÃÃo da recarga de aquÃferos. Na Chapada do Araripe ocorre reduÃÃo de vazÃes de fontes que surgem na encosta, e o desmatamento com seus efeitos na estrutura do solo e na recarga dos aquÃferos pode ser a causa. Na Chapada do Araripe existem planos de manejos florestais importantes para o desenvolvimento econÃmico regional; mas sem monitoramento podem provocar danos ao solo. Neste trabalho foram avaliados os parÃmetros: teores de matÃria orgÃnica e umidade do solo, capacidade de infiltraÃÃo, resistÃncia do solo Ã penetraÃÃo, macro e microporosidade e densidade de indivÃduos da macrofauna edÃfica de uma unidade de manejo florestal de vegetaÃÃo nativa na Chapada do Araripe, comparando-os com os de uma Ãrea preservada. As amostras de solos coletadas foram ordenadas em trÃs grupos de matÃria orgÃnica quantitativamente semelhante, sendo o de maior valor representativo da floresta preservada (Grupo 1) e os demais representativos das Ãreas manejadas (Grupos 2 e 3). Os talhÃes jÃ explorados (Grupo 3) apresentaram menor teor de matÃria orgÃnica que os talhÃes com exploraÃÃo em andamento, os ainda nÃo explorados e o da Ãrea de reserva legal (Grupo 2). O Grupo 1 apresentou maior teor de umidade e capacidade de infiltraÃÃo. No perÃodo seco a umidade deste grupo foi superior Ã dos demais, mesmo no perÃodo chuvoso, indicando que o aporte de matÃria orgÃnica conserva a umidade. A capacidade de infiltraÃÃo no Grupo 1 apresentou menor variaÃÃo, indicando solos de infiltraÃÃo homogÃnea; no Grupo 2 apresentou valor intermediÃrio, indicando solos em fase de recuperaÃÃo, tendendo a homogeneidade da infiltraÃÃo; e no Grupo 3 apresentou valor elevado, indicando solos com infiltraÃÃo heterogÃnea. Na profundidade de 0 a 40 cm, os solos do Grupo 1 apresentaram menor resistÃncia Ã penetraÃÃo que os dos Grupos 2 e 3; mas na profundidade de 40 a 60 cm, nÃo apresentaram diferenÃa significativa, indicando fraca interferÃncia das aÃÃes antrÃpicas neste perfil. A macroporosidade apresentou maior valor para o Grupo 1, mostrando que a quantidade elevada de matÃria orgÃnica Ã associada com o aumento de macroporos, levando a uma reduÃÃo da resistÃncia Ã penetraÃÃo e consequentemente, a um aumento da capacidade de filtraÃÃo. A densidade de indivÃduos da macrofauna edÃfica no perfil de 0 a 30 cm de solos apresentou maior valor mÃdio para o Grupo 1, intermediÃrio, para o Grupo 2 e menor, para o Grupo 3. Verificou-se que as aÃÃes antrÃpicas na vegetaÃÃo e no solo reduziram direta e indiretamente o teor de matÃria orgÃnica, a densidade de indivÃduos da macrofauna edÃfica e a porosidade biolÃgica, contribuindo com uma reduÃÃo na infiltraÃÃo de Ãgua.
Anthropization of native forests causes imbalances of ecosystems, changing the physical, chemical and biological properties of soil. Among those imbalances, we can mention the reduction in groundwater recharge. Springs or the slope of the Araripe plateau show signification reduction in discharges, and deforestation, with its effects on soil structure and on the recharge to aquifers, may be the cause. For the Araripe plateau there are forest management plans aiming at regional economic development; but without monitoring those plans can cause soil damage. In this study we evaluated the following parameters of the soil macrofauna a forest management unit of native vegetation on the Araripe plateau and compared them to the parameters in a preserved area: levels of organic matter and soil moisture, infiltration capacity, soil resistance to penetration, macro and micro porosity and density of individuals.of soil macrofauna. Soil samples collected were sorted into three groups of quantitatively similar organic matter, so that the group having the highest value represented preserved forest (Group 1) and the other groups represented managed areas (Groups 2 and 3). The plots already exploited (Group 3) presented lower organic matter content than those under exploitation, those not yet exploited and that of legal reserve area (Group 2). Group 1 presented a higher moisture content and infiltration capacity. Even in the dry period, the moisture of this group was higher than that of the others in the rainy season, indicating that the organic matter maintains moisture. The infiltration rate in Group 1 presented a lower coefficient of variation, indicating soils of homogeneous infiltration; Group 2 presented an intermediate infiltration variation, indicating soils under restoration and tending to uniformity of infiltration; and Group 3 showed a high level of infiltration rate variation, indicating soils with heterogeneous infiltration. In the 0 to 40 cm layer. Soils from Group 1 had a lower resistance to penetration than those from Groups 2 and 3. However, at depths from 40 to 60 cm, soils did not differ significantly, indicating a low influence of anthropogenic activity in this profile. The macroporosity presented a higher value for Group 1, indicating that the high amount of organic matter contributes to the increase in macropores, leading to a reduction in resistance to penetration and, as a result of that, to an increase in infiltration capacity. The density of individuals of the soil macrofauna in the upper 30 cm layer and soil presented the highest average value for Group 1, an intermediate value for group 2 and the lowest one for Group 3. We observed that the anthropogenic influences on vegetation and soil cause a direct and indirect reduction in the organic matter content, in density of individuals of the soil macrofauna and in biological porosity, contributing to a lower water infiltration rate.

A antropização de florestas nativas causa desequilíbrios de ecossistemas, modificando propriedades físicas, químicas e biológicas do solo. Dentre os efeitos encontra-se a redução da recarga de aquíferos. Na Chapada do Araripe ocorre redução de vazões de fontes que surgem na encosta, e o desmatamento com seus efeitos na estrutura do solo e na recarga dos aquíferos pode ser a causa. Na Chapada do Araripe existem planos de manejos florestais importantes para o desenvolvimento econômico regional; mas sem monitoramento podem provocar danos ao solo. Neste trabalho foram avaliados os parâmetros: teores de matéria orgânica e umidade do solo, capacidade de infiltração, resistência do solo à penetração, macro e microporosidade e densidade de indivíduos da macrofauna edáfica de uma unidade de manejo florestal de vegetação nativa na Chapada do Araripe, comparando-os com os de uma área preservada. As amostras de solos coletadas foram ordenadas em três grupos de matéria orgânica quantitativamente semelhante, sendo o de maior valor representativo da floresta preservada (Grupo 1) e os demais representativos das áreas manejadas (Grupos 2 e 3). Os talhões já explorados (Grupo 3) apresentaram menor teor de matéria orgânica que os talhões com exploração em andamento, os ainda não explorados e o da área de reserva legal (Grupo 2). O Grupo 1 apresentou maior teor de umidade e capacidade de infiltração. No período seco a umidade deste grupo foi superior à dos demais, mesmo no período chuvoso, indicando que o aporte de matéria orgânica conserva a umidade. A capacidade de infiltração no Grupo 1 apresentou menor variação, indicando solos de infiltração homogênea; no Grupo 2 apresentou valor intermediário, indicando solos em fase de recuperação, tendendo a homogeneidade da infiltração; e no Grupo 3 apresentou valor elevado, indicando solos com infiltração heterogênea. Na profundidade de 0 a 40 cm, os solos do Grupo 1 apresentaram menor resistência à penetração que os dos Grupos 2 e 3; mas na profundidade de 40 a 60 cm, não apresentaram diferença significativa, indicando fraca interferência das ações antrópicas neste perfil. A macroporosidade apresentou maior valor para o Grupo 1, mostrando que a quantidade elevada de matéria orgânica é associada com o aumento de macroporos, levando a uma redução da resistência à penetração e consequentemente, a um aumento da capacidade de filtração. A densidade de indivíduos da macrofauna edáfica no perfil de 0 a 30 cm de solos apresentou maior valor médio para o Grupo 1, intermediário, para o Grupo 2 e menor, para o Grupo 3. Verificou-se que as ações antrópicas na vegetação e no solo reduziram direta e indiretamente o teor de matéria orgânica, a densidade de indivíduos da macrofauna edáfica e a porosidade biológica, contribuindo com uma redução na infiltração de água.

Abstract:

AbstractGlioblastoma multiforme (GBM) develops on glial cells and is the most common as well as the deadliest form of brain cancer. As in other cancers, distinct combinations of genetic alterations in GBM subtypes induce a diversity of metabolic phenotypes, which explains the variability of GBM sensitivity to current therapies targeting its reprogrammed metabolism. Therefore, it is becoming imperative for cancer researchers to account for the temporal and spatial heterogeneity within this cancer type before making generalized conclusions about a particular treatment’s efficacy. Standard therapies for GBM have shown little success as the disease is almost always lethal; however, researchers are making progress and learning how to combine therapeutic strategies most effectively. GBMs can be classified initially into two subsets consisting of primary and secondary GBMs, and this categorization stems from cancer development. GBM is the highest grade of gliomas, which includes glioma I (low proliferative potential), glioma II (low proliferative potential with some capacity for infiltration and recurrence), glioma III (evidence of malignancy), and glioma IV (GBM) (malignant with features of necrosis and microvascular proliferation). Secondary GBM develops from a low-grade glioma to an advanced-stage cancer, while primary GBM provides no signs of progression and is identified as an advanced-stage glioma from the onset. The differences in prognosis and histology correlated with each classification are generally negligible, but the demographics of individuals affected and the accompanying genetic/metabolic properties show distinct differentiation [3].

Abstract:

Urban drainage has become one of the most important aspects of urban development. Ensuring long-term functioning of sewer systems and waste-water treatment plants is associated with constantly rising costs, and it is clear nowadays that the contemporary method of urban drainage cannot possibly be implemented worldwide because of the financial burden. The existing method of urban drainage continues to threaten the status of water flow and water sources. Urban hydrology has evolved to improve the way urban run-off is managed for flood protection, public health and environmental protection. The essence of the future solution resides in finding an acceptable compromise or an alternative solution for rainwater drainage from urban areas. The content of this paper is research focused on the infiltration of water from surface run-off and comparison of ground testing, laboratory analysis and numerical analysis of filtration coefficient. The foundation for improving the effectiveness of urban drainage will be created through the proposal and comparison of infiltration conditions. The topic of the paper emerged because of insufficient information about infiltration systems in the Slovak technical regulations and the lack of support for water infiltration from surface run-off. This paper points out the fundamentals, principles and development of proposals for infiltration facilities. The aim of the paper was to expand the body of scientific knowledge in research and solutions for infiltration of water from surface run-off with emphasis on the infiltration capacity of the selected area and intensity of precipitation.
