In the present Outcome Based Education in Engineering, higher order skills in psychomotor domain are required as per Dave’s Taxonomy,Simpson’s Taxonomy and Anita Harrow’s Taxonomy.Not only computational skills are required but also experimental skills to develop the engineering skills life long. According to Walter J. Rawls et.al(1993), infiltration and soil water movement play a key role in surface runoff, groundwater recharge,evapotranspiration, soil erosion and transport of chemicals in surface and subsurface waters.The ASTM International Standard D 3385- 03 describes the “ Standard Test Method for Infiltration Rates of Soils in field using Double Ring Infiltrometer”. The present paper describes the methodology of development of Kostiakov Infiltration Equations from the field tests of Double Ring Infiltrometer,as part of various student projects of design and evaluation of irrigation methods. As properties of soil also influence the infiltration rate, soil properties are also determined. In one test, the Kostiakov infiltration equation fitted is in the form y=0.44t0.65. The basic infiltration rate is 44 millimeters/hour. Other methods of infiltration equations are briefly mentioned.\

Infiltration models are used in designing and optimizing irrigation projects as they are capable of predicting infiltration rate and accumulated infiltration depth to a reasonable level of accuracy. The objective of this study deals with obtaining the parameters of infiltration models like Kostiakov and Philip, applying these models to the soil of Dediapada and evaluating their performance by comparing it with the observed infiltration. Firstly, the accumulated infiltration and infiltration rates were determined by the field measurement using a double ring infiltrometer. Kostiakov’s and Philip’s infiltration models were then applied to obtain simulated data once its parameters were ascertained. The estimated parameters ‘m’ and ‘n’ for the Kostiakov model were 0.1311 and -0.3092 respectively and the corresponding equations obtained for estimating infiltration rate and accumulated infiltration depth were 0.13t-0.30 and 0.19t0.69. The estimated parameters ‘s’ and ‘k’ for the Philip model were 0.32 and 0.014 respectively and the corresponding equations obtained for estimating infiltration rate and accumulated infiltration depth were 0.16t-0.5+0.014 and 0.32t0.5+0.014t. The coefficient of determination values for evaluating the performance of the model were obtained in excess of 0.95 for both the models. Due to lack of research on the application of infiltration models on the clay loam soil of Dediapada, this study would prove to be useful for estimation of infiltration rate and depth.

INFILTRAÇÃO DE ÁGUA EM UM LATOSSOLO ROXO MUITO ARGILOSO EM DOIS SISTEMAS DE MANEJO   Mário Artemio UrcheiCarlos Ricardo FietzEmbrapa Agropecuária Oeste, Caixa Postal 661, 79804-970 – Dourados, MSE-mail: [email protected] e [email protected]   1 RESUMO              Este trabalho objetivou caracterizar a infiltração de água em um latossolo roxo muito argiloso em dois sistemas de manejo (preparo convencional - PC e plantio direto - PD) e avaliar a adequação das equações de Horton e Kostiakov-Lewis para a estimativa da taxa de infiltração básica. O trabalho foi desenvolvido na área experimental da Embrapa Agropecuária Oeste, em Dourados, MS, durante os anos de 1994 e 1995. Em cada um dos sistemas foram realizados 25 testes de infiltração pelo método do infiltrômetro de duplo cilindro. Considerou-se como taxa de infiltração básica observada a média aritmética dos valores lidos após 120 minutos, enquanto sua estimativa foi feita pelas equações de Horton e de Kostiakov-Lewis. A taxa de infiltração básica, nos dois sistemas de manejo, ajustou-se à distribuição normal, de acordo com o teste de Kolmogorov-Smirnov, sem diferença entre as médias de 92,2 e 92,8mm h-1 (Tukey, 5%), para os sistemas PC e PD, respectivamente, consideradas muito altas. Esses valores apresentaram alta variabilidade nos dois sistemas, com coeficientes de variação de 78,6% para o PC e 83,5% para o PD. Apesar de as duas equações terem apresentado bom ajuste, os índices estatísticos evidenciaram que a equação de Kostiakov-Lewis é mais adequada para estimar a taxa de infiltração básica no latossolo roxo estudado.   UNITERMOS: Equações de infiltração, plantio direto, preparo convencional.   URCHEI, M. A.,  FIETZ, C.R.  WATER INFILTRATION IN AN OXISOL UNDER TWO CROPPING SYSTEMS   2 ABSTRACT   This work aimed to characterize water infiltration and evaluate the adequacy of Horton and Kostiachov-Lewis’s equations to estimate basic infiltration rate in an Oxisol under conventional tillage (CT) and no tillage (NT). The work was carried out over 1994 and 1995 in an experimental area of Embrapa Agropecuaria Oeste in Dourados city, Mato Grosso do Sul State, Brazil. For each  system  25  infiltration  tests  were  performed  by  the  double  ring infiltrometer method. Basic infiltration rates were  the average  of  infiltration measured  after  120 min of adding water on the soil surface. Estimation of basic infiltration rates has been performed by using Horton and Kostiakov-Lewis’s equations. Basic infiltration rates in both systems followed normal distribution according to Kolmogorov-Smirnov’s test. Average values for basic infiltration were 92.2 and 92.8 mm h-1 for CT and NT systems, respectively. No significantly different means have been observed  (P<0.05). The variation coefficients were 78.6% for CT and 83.5% for NT. In spite of two equations good adequacy, statistical indexes showed that Kostiakov-Lewis’s equation has been more fitted to estimate basic infiltration rates for the  studied Oxisol.  KEYWORDS: Infiltration equations, no tillage, conventional tillage.

The processing of adequate information of characteristics of soils is essential for designing quality soil management and construction practices on agricultural and urban lands. Little is known about the infiltration capacity of soils in institutions of higher learning, this study therefore evaluated the infiltration capacity of soils in the Landmark University, Omu-Aran. The double ring infiltrometer with an inner ring of 30 cm and a 50 cm diameter outer ring with a height of 30 cm above the ground was used to test infiltration rates at two sites, namely the University of Omu-Aran’s orchard area (OA) and the new college building area (NCBA). Six points labelled (A, B, C, D, E and F) were identified at 10 m grid intervals at which infiltration rates were determined using a 30 cm inner ring double ring infiltrometer and a 30 cm height outer ring. Results of soil analysis suggests sand dirty and silt texture and bulk density and particle density varied from 2.54–3.03 g/cm3 and 1.31–1.52 g/cm3 respectively. The infiltration rates ranged between 0.007 to 0.011 cm/sec with a mean of 0.009cm/sec in orchard area (OA) and 0.011 to 0.035 cm/sec with a mean value of 0.021 cm/sec in NCBA indicating a significant difference at both locations. The infiltration rate of soils at the OA is very low compare to that of NCBA therefore the OA is more prone to flooding. Effective drainage control system is recommended along the orchard area to prevent flooding.
