“…The only experimental point that did not meet the conditions imposed by Snow (1999) was the Banana R2, I sol = 27.81 < λ = 38.15. Netto et al (2013) also observed the non-validation imposed by Snow (1999) for some experimental points, but still considered the hypothesis to be valid, following the recommendations in Clothier et (1995), which reported that for columns I sol > 15 mm, the hypothesis can be considered valid. In this study, the infiltrated Brsolution (I sol ) was greater than 15 mm.…”

“…After the infiltration test and the addition of the tracer (Br -), the soil was sampled in the center of the cylinder up to a depth of 0.15 m with the same Uhland sampler, but using a ring 0.01 m high and 0.05 m in diameter; each sample ( Figure 1-b), a total of 15 samples, were used to measure the final water volumetric content, θ f (m 3 .m -3 ) and bromide concentration in the soil, C r (mg L -1 ). (Netto et al, 2013).…”

“…In this sense, knowing the behavior and destination of water and solute in the soil is of fundamental importance, especially in issues related to environmental impact. Since the 1960s, with the initial studies of solute transport in soils (BIGGAR;NIELSEN, 1962a,b;NIELSEN;BIGGAR, 1961), the amount of research in this area has increased considerably and with this the number of experimental situations in which mathematical modeling is applied. There are existing studies in the literature involving solute transport and other chemical substances in laboratory conditions (MILFONT et al, 2006;DING et.…”

However, there are few studies in Brazil related to the determination of hydrodispersive parameters under field conditions, especially with the semi-arid soils in northeastern Brazil (NETTO et al, 2013).…”

The determination of the hydraulic and hydrodispersive properties of soil is necessary for the understanding of water dynamics and soil solute transport, and they are used as input data in several models. Determinations of soil hydraulic and hydrodispersive parameters are usually obtained by separate methodologies. Axisymmetric infiltration tests using a single ring infiltrometer with a conservative tracer (KBr) in the field (Beerkan-Solute) lead to the determination of the most realistic hydraulic and hydrodispersive properties of the study area. The objective of this work was the hydrodynamic and hydrodispersive characterization of an irrigated soil, classified as Fluvic Cambisol, from the lowland areas of the northeastern semi-arid region, located in the backwoods of the state of Pernambuco, in the municipality of Serra Talhada-PE. The hydrodispersive parameters were determined with the CXTFIT 2.0 program, using the CDE and MIM models. The studied soil presented hydrodynamic characteristics with high values of sorptivity (S) that were associated with high values of saturated hydraulic conductivity (Ks), indicating that the soil has good permeability and resistance to surface crumbling caused by rain drops or soil management. It was observed the predominance of the convective process, being the CDE model the one that presented the best performance in the transport of the KBr tracer under field conditions, indicating the absence of two water regions mobile and immobile in the studied soil.

Os eventos pluviométricos extremos são causadores de diversas tragédias e transtornos. A drenagem urbana é de essencial relevância para combater estes problemas. Nem sempre as galerias urbanas conseguem absorver toda a demanda oriunda destes eventos, logo o maior aliado dessas é o solo natural. Poucos estudos visam quantificar a parcela de contribuição desse meio na drenagem nos centros urbanos. Este estudo teve como finalidade estimar o dimensionamento necessário das galerias pluviais para sanar estes problemas, utilizando os parâmetros do solo de taxa de infiltração e a capacidade volumétrica de retenção das águas pluviais, analisando o balanço hídrico em uma área comercial e academicamente importante da cidade do Recife – PE. Foram utilizados ensaios de granulometria e de infiltração a anel simples para modelar o balanço da água nas regiões de terreno natural da área pré-determinada. O solo mostrou-se bom condutor, sendo capaz de absorver chuvas diárias de quase 49mm em seu próprio limite físico. A dificuldade encontrada foram os baixos índices de terreno natural disponíveis na região - 17% do total, reduzindo sua atuação. Verificou-se que seriam necessários aproximadamente 410 l/s como vazão necessária da rede principal dessa área urbana, para absorver a maior parte dos eventos extremos de precipitação.
