“…Silt, clay, and sand content variabilities were classified as very high, medium, and low, respectively (53.35, 18.21, and 4.64% CV). These findings agree with those of Klinke, Oliveira and Pereira, (2017), who studied the physical properties of a Typic Haplustox (Oxisol) and obtained a very high variability for silt, medium for clay, and low for sand, with CVs of 52.03%; 17.37%; 6.18%, respectively. Thus, the granulometric attributes of the soil showed different variability, silt with very high variability, clay with medium variability, and sand with low variability, which indicates soil heterogeneity.…”

Effects of soil attributes using the geostatistical tool improves the interpretation of specific soil management. Thus, this study aimed to evaluate the physical, chemical, and microbiological properties of a Typical Haplustox (Oxisol), identifying those with the best linear and spatial correlation with eucalyptus (Eucalyptus spp.) vegetative growth. The experiment was conducted at the Teaching, Research, and Extension Farm (FEPE) of the Universidade Estadual Paulista (UNESP), Campus of Ilha Solteira. Thirty-five points spaced 13 meters apart were demarcated for analysis, which were distributed in 5 rows of 7 points each. From each point, 2 soil samples were collected from the 0-10 cm depth layer. The physical, chemical, and microbiological soil properties evaluated were: sand, silt, and clay contents; penetration resistance (PR), gravimetric moisture (GM), real density (RD), microbial biomass carbon (MBC), respirometry (CO2-C), metabolic quotient (qCO2), organic matter content (OM), and hydrogenionic potential (pH). The eucalyptus attributes assessed were: plant height (PH) and circumference at breast height (CBH). Each attribute was analyzed by descriptive statistics using the SAS software. Data frequency distribution was verified by the Shapiro Wilk method, and geospatial changes were analyzed by the GS+ software. The soil property that best explained the variability in eucalyptus dendrometric attributes was real density (RD). Except for RD, all properties did not show spatial dependence (i.e., pure nugget effect), which significantly represents eucalyptus vegetative performance.

“…This could be due to the textural variation and the consequent variation of the micro and macro porosity of the data, which were not measured and affected the result of the total porosity. Klinke Neto et al (2017) found a correlation of 0,53 the saturated hydraulic conductivity and macroporosity, being this the best result found among all attributes studied (texture, bulk density, total porosity, macroporosity and microporosity). Analyzing the spatial variability of the data, for the LVA soil class, the same authors found anisitropy only for the data of saturated hydraulic conductivity, macroporosity and total porosity.…”

This study investigated the influence of the environmental characteristics and soil properties on the soil infiltration rate in urban permeable area. The experiments were conducted at nine sampling points located in the urban perimeter of Campo Grande, capital city of Mato Grosso do Sul State, in the Brazilian Midwest. The infiltration rates were determined using a portable integrated rainfall and overland flow simulator. Each experiment was repeated three times, and a total of twenty-seven plots were collected. At the same time, environmental characteristics and soil physical properties, that may affect infiltration rate, were also evaluated. The relationship between the infiltration rate, the environmental plot characteristics and the soil physical properties was verified using a linear correlation matrix.

“…Klinke Neto et al (2017) analyzed soil erosion processes in a subbasin of the MGEES and applied the USPED (unit stream power erosion and deposition) model. The sub‐basin presented 60% of the area with low taxes of erosion processes (due to low declivities) and sandy texture of soils (from eroded sediments of Group Itararé rocks), which are deep with high storage capacity and permeability, favouring groundwater recharge.…”

Hydrogeochemical evaluation of groundwater and surface water interactions in an alluvial plain, Southeast Brazil

Alluvial plains are transition areas between terrestrial and aquatic environments where groundwater (GW) and surface water (SW) interactions occur. They are the subject of our present study, using hydrochemistry and environmental isotopes. Two water sampling campaigns in dry and wet seasons for studying physicochemical and natural isotope analysis provided 44 groundwater samples and watertable level measurements from monitoring wells and eight water samples from river, creek, and lake.In the dry season, lake and creek waters presented TDS (<3.64 mg L À1 ) and high values of TDS in groundwater and river (average 47.71 and 108.7 mg L À1 , respectively), showing CaMgHCO 3 , NaHCO 3 , and NaHCO 3 Cl types and precipitation prevalence. However, GW-SW interaction occurred in CaMgCl and CaMgSO 4 groundwater with TDS varying from 93.8 to 164.7 mg L À1 and weathering dominance close to riverbanks. The TDS, sulfate, and sodium were monitoring markers of this interaction. In the wet season, superficial waters and groundwater were more diluted, presenting CaMgHCO 3 , NaHCO 3 , and NaHCO 3 Cl types and precipitation dominance. Overall, the ion exchange was the main hydrochemical process. The δ 18 O, δ 2 H, and d-excess indicated groundwater recharge with a weak evaporation process, rainwater mixture, and water-rock interaction. Maps of the distribution of ions, isotopes, and d-excess showed GW-SW interaction along the riverbanks and depleted groundwater in a large portion of the alluvial plain. The alluvial plains are susceptible areas to precipitation changes due to fast and direct infiltration. Their monitoring can be essential to understand the climate variability and reduce impacts on the shallow aquifer that sustain forests and human life.pristine area, recharge and discharge, riparian zone, São Paulo State, shallow aquifer | INTRODUCTIONThe alluvial plains are considered a transition environment between aquatic and terrestrial ecosystems. They are groundwater discharge (or recharge) areas of local, intermediate, and regional hydrogeological systems (Fetter, 1994;Freeze & Cherry, 1979), relating them to GW-SW interactions, landscapes analysis, and climate conditions (Larkin & Sharp, 1992;Sophocleous, 2002).The GW-SW interactions are intrinsic processes of integrated watershed management, due to the connectivity and interactions between environments (biological, geological, climatic, and human) and water resource availability (quality and quantity).
