Full textTools for predicting rain garden performance are limited, particularly for predicting seasonal performance. Changes in temperature cause changes in the viscosity of water, infiltration rates, and evapotranspiration rates. A variably-saturated soil model, HYDRUS-1D, was calibrated and validated using observed ponding depth and soil moisture data for the Philadelphia Zoo Rain Garden, owned and operated by the Philadelphia Water Department (PWD). Warm and cold seasons were simulated with typical meteorological data and temperature-adjusted saturated hydraulic conductivity values. Design-storm simulations confirmed that the rain garden is over-performing. Maximum capacity of the system was simulated by increasing the loading ratio until overtopping occurred or ponding remained longer than 24 hours. This study will demonstrate how modeling of an operational urban rain garden offers a realistic picture of performance and could be used as a tool for informing regulations and design.

Full textMathematical models are commonly used in studies of water dynamics in unsaturated soil. The main equation to quantify water the dynamics is the differential Richards equation. Its analytical solution is impossible in almost all cases, requiring numerical methods, among which the Van Genuchten - Mualem water conductivity and water retention functions are frequently used to obtain the numerical solution. The objective of this work is to present a new method to obtain the Van Genuchten - Mualem parameters, using the inverse modeling of water content data measured periodically by gamma radiation attenuation in evaporating samples. Hydrus-1D software was used for the inverse modeling. The method was tested in samples with different textures, collected in 11 locations in the region of Piracicaba, state of São Paulo, Brazil. Of the sets of samples analyzed, only one presented an unsatisfactory result, concluding that the method is valid

Full textThe concern about the fate of chemical products and water, applied to the soil, has been motivating several researchers to develop and apply theoretical models, aiming to describe the physical processes involved in the transport of those products in soil profile. The present research had as objective the application of the model Hydrus- 1D for water and solute (nitrate and potassium) simulation profile, in laboratory conditions, using soil columns filled with two types of unsaturated soil (Oxisol (Haplustox) and Hapludox), as well to evaluate the acting and sensitivity of the model. The transport parameters were obtained for each solute by breakthrough curves (BTCs). The transport parameters obtained and the boundary conditions were inserted in the Hydrus-1D model to realize the simulations. The acting of the Hydrus-1D model was evaluated using the statistical indicators: maximum error, mean absolute error, normalized root mean-square error, coefficient of residual mass, determination coefficient, efficiency and Willmott concordance index. The model sensitivity was evaluated by the method proposed by McCuen and Snyder (1986) and applied to the parameters: input flow, soil saturated hydraulic conductivity, water content (saturation point), alpha and n (soil water retention curve parameters), distribution coefficient and dispersivity. The obtained results, experimentally, showed the nitrate displacement following the wetting front and, in relation to the potassium ion, a larger retention was observed at the superficial soil columns layers. Therefore, was possible to conclude that Hydrus-1D model was efficient for both water and potassium displacement simulations, for both studied soils and by the balance model for solute transport in soil, the Hydrus- 1D model was not efficient to simulate the nitrate displacement in both soils. The experimental procedures to estimate transport parameters, by the BTCs, were enough to describe the potassium movement in soil, generating input information necessary to the model simulation. To the simulation of the nitrate displacement, was possible to conclude that the model Hydrus-1D requests a more detailed experimental process, being necessary the estimate of a larger number of transport parameters. In relation to the sensitivity analysis of the Hydrus-1D model, when simulated the content of potassium and water at the soil columns, was observed that the model shows more sensitivity about to the parameters: water content (saturation point) and input flow. This parameters need to be estimated with more precision. There was a low sensitivity to the parameters soil saturated hydraulic conductivity and dispersivity for both studied soils.

Full textThe increased demand for food due to population growth requires that agricultural practices become increasingly intensive and very technical, including the increased use of agricultural chemicals (fertilizers). If improperly applied without considering possible impacts on natural resources, agricultural chemicals may lead to soil and groundwater contamination through their leaching from the soil root zone. They may be responsible also for increased salinity in some soils of semiarid regions in northeastern Brazil. Since many transient physical and chemical processes affect their transport in the subsurface, mathematical models have become popular tools in soil and water engineering and management in order to understand the correlation between water dynamics and solute movement in soils. Thus, this research aimed at using the HYDRUS-1D software package to simulate water and potassium movement, under laboratory conditions, in unsaturated saline soil columns filled with two soil types: an Ultisol (S1) and an Oxisol (S2). Comparisons were made with experimental data while also a sensitivity analysis was carried out to evaluate the effect of various parameters on solute transport under saline conditions. For this purpose the following studies were performed: 1) Measurement of solute breakthrough curves (BTCs) to estimate the transport parameters of the potassium ion by applying potassium solutions of 1,000 ppm, 2,000 ppm and 3,000 ppm to both soil types, 2) Application of similar potassium solutions to columns containing the same saline unsaturated soils, 3) Simulation of water and potassium distributions for different saline soil materials using HYDRUS-1D, and 4) Performance evaluation and sensitivity analyses of the HYDRUS-1D numerical model. The performance evaluation was conducted using the following statistical indices: maximum error, mean absolute error, normalized root mean square error, coefficient of residual mass, coefficient of determination, efficiency and Willmott\'s concordance index. The sensitivity analyses considered standard deviations resulting from positive and negative changes (+ 10% + 20% + 30% + 40% + 50%) (-10%, -20%, -10%, -40%, -50%) in the values of the saturated volumetric soil moisture content, the saturated hydraulic conductivity, and the parameters n and ? of van Genuchten\'s (1980) model for the unsaturated soil hydraulic functions. Results indicate that the experimental procedures (BTCs) for estimating the transport parameters of potassium for saline soil conditions were sufficient to describe potassium ion transport in the soils by generating the required input information for the simulation models. Relative to HYDRUS-1D model, the displacement of potassium was found to follow closely the wetting front, with the model providing a very efficient means for simulating the movement of both water and potassium in the two soils during saline conditions. The sensitivity analysis showed that the model was relatively sensitive to negative variations of the input data, notably the saturated water content, the saturated hydraulic conductivity, and the n and ? soil hydraulic parameters.

Na atualidade, metade da população mundial reside nos grandes centros urbanos. Grande parcela desse crescimento tem ocorrido em países em desenvolvimento. No Brasil, já se verifica um contingente de cerca de 80% da população residindo nas áreas urbanas. Neste crescente cenário de urbanização, impactos ambientais e socioeconômicos decorrentes de eventos hidrológicos têm sido recorrentes, afetando grande parte da população. O aumento da impermeabilização reduz as taxas de infiltração, que por sua vez leva à diminuição das taxas de recarga para os aquíferos e à diminuição do escoamento de base. O escoamento superficial é intensificado, aumentando em velocidade e, a frequência e magnitude dos picos de cheia, levando ocasionalmente às enchentes. Nesse contexto, têm sido empregados os telhados verdes em várias partes do mundo principalmente com finalidades estéticas de valorização do espaço urbano e para melhoria do conforto ambiental. Essas áreas verdes podem servir também para detenção do escoamento superficial, minimizando as enchentes urbanas. A simulação da dinâmica da água no solo do telhado verde realizada no programa Hydrus 1-D, a partir das características do sistema do teto verde implantado e dados obtidos em campo, proporcionou a caracterização da dinâmica da água em seu perfil de solo, fornecendo subsídios quanto ao desempenho deste dispositivo no amortecimento do escoamento superficial oriundo dos telhados

Full textSoils subjected to successive pig slurry (PS) amendments present zinc (Zn) and copper (Cu) increases, mostly on soil surface layer. The continuous application of PS causes accumulation of these heavy metals (HM) in soil, increasing risks for environmental contamination. Therefore, development of methods to estimate Zn and Cu accumulation in surface layer and their movement in soil is very important for the management planning of PS and of the agricultural soils amended with these residues. The main objective of this work was to model the vertical transport of Zn and Cu in profile of agricultural soils receiving successive application of PS at high, moderate and low doses, evaluating the effects of soil tillage and water absorption by roots on the movement of these HM. We also aimed to predict the long-term accumulation of HM in soil surface and their transport into groundwater, comparing estimated results with the threshold values established for agricultural soils and groundwater by the Conselho Nacional do Meio Ambiente (CONAMA). Two studies were performed on field experiments composed by different PS doses, the first located on an Alfisol in Santa Maria RS, and the second on an Oxisol in Campos Novos SC. Hydro-physical and chemical characteristics of these soils were measured and, accompanied by atmospheric and PS application data sets, were introduced into HYDRUS-1D for parameterization of the two-site model used. In the first study, simulations for next 100 years were performed under scenarios combining two PS doses and four time intervals between soil tillage of the arable layer. The solute transport model used on these simulations was already validated for this local soil in another study. In the second study, the validation of a solute transport model was carried out primarily, following the same approaches used for the Alfisol. Afterwards, root water uptake and root growth modules were introduced to the model. The future scenarios were simulated using applications of different PS doses during the next 50 years. The solute transport model previously validated for the Alfisol was also validated for the Oxisol, and the introduction of the root modules in HYDRUS-1D produced even better results. This increased the usefulness of the model for its use in simulations related to Zn and Cu transport on other contaminated soils. Future scenarios exhibit a great accumulation of these two HM in soil surface layer during the simulated times. Moreover, when soils are submitted to high PS annual doses, its Cu concentrations reached the maximum values established by CONAMA for agricultural soils in approximately 94 years on the Alfisol and in 29 years on the Oxisol. Reduction in PS doses and sporadic soil tillage are strategies that slow the increase of these HM concentrations in soil surface layer, decreasing so the environmental risks and making PS additions on agricultural soils viable for longer time.
Solos submetidos a sucessivas aplicações de dejeto líquido de suínos (DLS) apresentam incrementos nos seus teores de zinco (Zn) e cobre (Cu), principalmente na camada superficial. A continuidade dessa prática faz com que esses metais pesados (MP) se acumulem no solo, aumentando o potencial de contaminação do ambiente. Dessa forma, o desenvolvimento de métodos que estimem o acúmulo superficial e o movimento de Zn e Cu no solo é de extrema importância no planejamento do manejo dos DLS e dos solos agrícolas que recebem esses resíduos. O trabalho objetivou modelar o transporte vertical de Zn e Cu no perfil de solos agrícolas contaminados por aplicações sucessivas de altas, moderadas e baixas doses de DLS, avaliando o efeito do revolvimento do solo e da absorção de água pelas raízes no movimento desses MP, prevendo, no longo prazo, seus acúmulos na camada superficial do solo e suas transferências rumo ao lençol freático, confrontando os resultados estimados com os respectivos limites de concentração para solos agrícolas e águas subterrâneas estabelecidos pelo Conselho Nacional do Meio Ambiente (CONAMA). Foram realizados dois estudos em experimentos de campo com diferentes doses de DLS, o primeiro localizado sobre um Argissolo, em Santa Maria RS, e o segundo sobre um Latossolo, em Campos Novos SC. Diversas características físico-hídricas e químicas foram determinadas nesses solos para, juntamente com os dados atmosféricos e do histórico de aplicação de DLS nessas áreas, serem introduzidos no HYDRUS-1D para parametrização do modelo químico de dois sítios utilizado. No primeiro estudo foram realizadas simulações para os próximos 100 anos, considerando cenários combinando duas doses de DLS e quatro intervalos de tempo entre revolvimentos periódicos da camada arável do solo. O modelo de transporte de solutos utilizado nessas simulações já havia sido validado para o solo deste local em outro trabalho. No segundo estudo foi feita a validação de um modelo de transporte de solutos, seguindo as mesmas premissas do modelo utilizado no Argissolo. Posteriormente, módulos de absorção de água e crescimento de raízes foram incorporados ao modelo. Realizaram-se então simulações futuras de cenários considerando aplicações de diferentes doses de DLS durante os próximos 50 anos. O modelo de transporte de solutos validado previamente no Argissolo foi validado também no Latossolo, apresentando resultados ainda melhores quando os módulos de raízes foram introduzidos no HYDRUS-1D. Isso aumenta a abrangência desse modelo para simular o transporte de Zn e Cu em outros solos contaminados. Os cenários futuros mostram que ocorre grande acúmulo desses MP na camada superficial do solo durante os períodos simulados. Além disso, quando os solos são submetidos a altas doses anuais de DLS, as suas concentrações de Cu atingem os valores máximos estipulados pelo CONAMA, para solos agrícolas, em aproximadamente 94 anos no Argissolo e 29 anos no Latossolo. Reduzir as doses de DLS e revolver o solo esporadicamente são alternativas que retardam o aumento da concentração desses MP na camada superficial do solo, diminuindo o potencial de impacto ao ambiente e tornando a adição de DLS em áreas agrícolas viável por mais tempo.
