“…Water dynamics in the soil is an essential continuous process both for studies focused on investigating surface runoff and flooding, mainly in urbanized areas, and for studies conducted in agricultural areas, since it can affect water and nutrient availability for plants. It can be described, among other methods, based on water infiltration into the soil (NETTO et al, 2000), which, according to Cecílio et al (2013), refers to the process through which surface water enters the environment.…”

Water infiltration into the soil plays key role in proper soil and water conservation and management processes. The aim of the current study is to assess water behavior in soil infiltration processes by using the Horton and Kostiakov models. Double-ring infiltrometer method was used to determine water infiltration into the soil. In addition, soil samples were collected at depths of 0-10 cm, 10-20 cm and 20-30 cm, to determine soil moisture. Cumulative infiltration (IA) and instantaneous infiltration rates per time interval (TiR) were calculated. Equations describing the investigated phenomena were adjusted, according to the Horton and Kostiakov models. High water infiltration rate was observed at the beginning of the process, likely due to low moisture level at the top soil layer. Both models tend to underestimate the initial infiltration rate value. However, the Horton model tends to overestimate most of the instantaneous infiltration values up to 25 minutes. The Kostiakov model, on the other hand, tends to overestimate most of the instantaneous infiltration rate values after 80 minutes. Despite the large fluctuation observed in TiR values in the soil, the assessed models have satisfactorily described the infiltration behavior at the experimental site. Based on the heat map analysis, the Kostiakov model was the one capable of determining the infiltration values closest to actual one.

“…Increased erosion may result from increased runoff and lead to lower recharge of aquifers, reducing base flow and increasing maximum outflows of watercourses. The reverse process will occur if there is increased infiltration (Nearing et al, 2011;Cecílio et al, 2013). In this sense, the understanding of the mechanisms that are related directly or indirectly with the erosion process is a necessary step for an effective environmental management of the natural resources of a river basin, as Lelis et al (2012) points out.…”

Information regarding the soil erosive processes that comprise the detachment, transport and deposition, are essential when analyzing hydrological processes associated with the generation of the flow in the landscape and water recharge. The USPED (Unit Stream Power Erosion and Deposition) model has been applied in several regions around the world for providing more accurate estimates, since it adds a physical base that relates the relief morphology with the erosion-defining runoff parameters. The current study aims to analyze erosion and deposition using the USPED model in a sub-basin on Mogi Guaçu River’s margins, municipality of Mogi Guaçu, SP, Brazil, and generate subsidies for future diagnoses regarding areas in the region with greatercapacity for water storage, based on less erosion. The loss of mineral and organic particles arising from the erosive process changes the soil’s effective depth, texture and structure, directly and negatively impacting its capacity to absorb and retain water. 60% of the sub-basin’s area was unaffected by considerable processes of erosion and deposition, both due to the current arboreal vegetation, but also the smooth relief of the site. The erosion and deposition sites have totaled 23.42 and 15.76% of the sub-basin area respectively, being adjacent to one another and preferably near or within the drainage network. The results of the spatialization were validated by the Kappa Index and revealed that the UPSED model obtained an excellent agreement with the “ground truth”. Stability in terms of erosion, favors the water recharge in area, since the soils present a sandy texture and in addition, the Latossolos, which make up 63% of the sub-basin, are deep and possess a high water storage...

“…O teste de infiltração é imprescindível para a elaboração de um projeto de irrigação com objetivo de obter maior rendimento das culturas. Entre as propriedades físicas do solo, a infiltração é uma das mais importantes quando se estudam fenômenos que estão ligados ao movimento de água e quantificar a parcela de chuva e a lâmina de irrigação que não infiltra no solo, ocasionando o escoamento superficial(CECÍLIO et al, 2013).…”
