“…Analogous dependencies have also been made for smooth plastic pipes because, in some cases, separate (autonomous) lines are installed for draining surface water. A range of dependencies is suggested by Gurklys et al (2008) to perform the hydraulic calculations of the water drainage line installing clay smooth or corrugated plastic pipes. Gurklys and Miseckaitė (2010) carried out detailed analysis and additional hydraulic testing on the stand with smooth and corrugated plastic pipes.…”

The relevance of research on removing surface water from the drained areas has increased along with a rising number of drainage systems. A large part of inlets for surface water are installed in the ditches of road safety zones and / or terrain drops in safety zones where flowing surface water accumulates. The practice of constructing and rebuilding roads in Lithuania shows that each new route of the road section most frequently passes through the drained area and redistributes runoff characteristics of that sector. Each subgrade passing through the watercourse of surface water is a local dam for surface runoff. The surface water that has accumulated in road safety zones have to be drained to avoid damage to road structures and from the flood in the drained roadside areas. The article discusses the efficiency of hydro technical measures such as inlets for surface water in the mining area and highlights the specificities of hydraulic calculations when the complete drainage system for surface water Inlet–Water Drainage Line is integrally assessed. The paper also proposes a methodology for the hydraulic calculations of the system Inlet–Water Drainage Line. The article examines the condition of water inlets having the F-5 or PN-42 structure. The findings of the research carried out in 2017 demonstrate that only 15.3% of inlets for surface water were completely clean, 45.2% of the inlets were found fully contaminated and 39.5% of those were partially silted up. Thus, a clear upward trend towards polluting the crosssectional areas of inlets for surface water with soil and grass root plants and a strong downward trend towards clean cross-sectional areas of inlets for surface water are observed. 22.6% of inlets for surface water were found damaged by farmers using tillage machinery.

“…Também é usada para especificar a taxa de transmissão de água através do solo. A condutividade hidráulica também pode se alterar com o passar do tempo devido às ações químicas, mecânicas, além de outras práticas agrícolas (USDA, 2001;Kumar et al, 2006;Gurklys et al, 2008). Na condição de não saturação e em virtude da sua importância quanto ao grau complexidade, o movimento de água no solo tem sido um dos tópicos mais influentes e pesquisados na física do solo nas últimas décadas (Biassusi, 2001;Madramootoo et al, 2007;Schultz et al, 2007;Stalnacke & Gooch, 2010).…”

R E S U M ONeste trabalho se obteve uma expressão algébrica para o modelo de Dumm através do qual se descrevem suas soluções por meio de algoritmo geométrico. Utilizaram-se as técnicas de identificação de padrões potenciais, hiperbólicos, lineares e exponenciais, por intermédio de representações em gráficos monolog e dilog visando definir estratégias de ajuste pela técnica dos mínimos quadrados, sentido em que foram analisados diversos modelos e se identificou que os modelos do tipo linear e potencial ajustam muito bem a razão entre os níveis do lençol freático inicial e após t dias decorridos; além disto, a identificação de que modelos potenciais podem ajustar bem o processo, possibilitou gerar, com o uso do Solver, Office Excel da Microsoft. Inc., modelos simplificados para o problema, razão pela qual se propõe, neste estudo, o ajuste com equações empíricas do tipo potencial para representá-lo com o uso das variáveis: condutividade hidráulica, profundidade e tempo para determinar a distância entre drenos permitindo, inclusive, a descrição dessa distância sob os mesmos parâmetros que o modelo de Glover-Dumm. As soluções encontradas têm pequenas diferenças porém não significativas quanto aos modelos de Glover, Dumm e Glover-Dumm. Equations obtained from laws of conservation for design of underground drains A B S T R A C TIn this study an algebraic expression for the Dumm's model was obtained, which describes its solutions through a geometric algorithm. An algebraic expression was obtained to model the Dumm through which to describe their solutions through geometric algorithm.The techniques of identifying potential, hyperbolic, linear and exponential patterns were used, through representations in monolog and dilog aimed at defining strategies set by the technique of least squares. In this context, different models were analysed and identified that linear and potential type models adjust well to the ratio of the initial ground water table levels and days elapsed after t. Furthermore, the identification that the potential models adjust well to describe the process as well, it was possible to generate simplified models for the problem, using the Solver, Microsoft Office Excel. Inc., and for this reason, in this study, it is proposed to fit with empirical equations of potential type to represent it using the variables such as hydraulic conductivity, depth and time to determine the distance between drains, including the description of this distance under the same parameters as the model of Glover-Dumm. The solutions found present small differences but not significant compared to models Glover, Glover-Dumm and Dumm. Palavras
