study of the spatial variability of infiltration characteristics is essential to estimating infiltration parameters on a local scale. the objectives of the present study were to scale the parameters of a philip two-term model for infiltration and survey the variability of infiltration characteristics geostatistically using wastewater in the bajgah catchment. infiltration was measured at 30 poin...
The aim of this study was to evaluate the spatial distribution of soil infiltration using geostatistics methods in a regional scale on 400 hectares of Mansour Abad Plain, in Larestan region, Fars Province. Sampling and parameters measurement were done for 78 points in a regular grid with a distance of 100*100 meters; for these variables, the best variogram model between linear, exponential, Gau...
infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...
The process of infiltration is one of the most important components of the hydrological cycle. On the other hand, the direct measurement of infiltration process is difficult, time spending and expensive. Infiltration models play a main role in managing water resources. Therefore, different types of models with various degrees of complexity were developed to reach this aim. So, this research ca...
growth analysis is a valuable method in the study of quantitative of growth, development and crop production. in order to study the physiological growth indices of lentil plant under dry- farming conditions, an experiment was carried out as a randomized complete block design with three replications at the agricultural research station of lorestan university during 2010. in this experiment two c...
DAS Lesti, Kabupaten Malang mengalami alih fungsi lahan yang besar akibat pesatnya pembangunan di era modern ini sehingga mempengaruhi laju infiltrasi. Studi ditujukan guna mengetahui infiltrasi dengan Model Horton dan Philip, kemudian didapatkan model memiliki prediksi paling sesuai pengukuran lapangan. Pengambilan data berupa hubungan antara waktu besarnya penurunan air titik-titik menggunaka...
infiltration and its modeling are important in design and implementation of irrigation projects, drainage, water-resources management, soil-conservation, hydrological studies, and artificial-recharge of groundwater and are influenced by different characteristics of soil and infiltrated water including the amount of salinity and sodium. the aim of this study was to evaluate the infiltration mode...
