ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...
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...
abstract quantitative investigation of effects of range management treatments on different soil and water components in rangeland ecosystems has been rarely taken into account. in the present research, the kodir summer rangeland in the southeast nowshahr in mazandaran province was selected for studying effects of open grazing and exclosure managements on infiltration, runoff and microrelief. ex...
UNLABELLED A set of 209 dwellings that represent 80% of U.S. housing stock is used to generate frequency distributions of residential infiltration rates. The set of homes is based on an analysis of the 1997 U.S. Department of Energy's Residential Energy Consumption Survey, which documents numerous housing characteristics including type, floor area, number of rooms, type of heating system, found...
use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems is not an accurate approach; because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study, the infiltration parameters were determined under real conditions of a center pivot system. for this purpose, a single ri...
ارائه یک مدل شبکه عصبی مصنوعی برای تخمین نفوذ آب در خاک بر اساس پارامترهای مدلهای SCS و کوستیاکوف
Infiltration of water into the soil accounts as a phenomenon in which most of researchers and scientists are interested so it acts a prominent role in the water cycling. Owing to temporal and spatial variation of infiltration, measuring of it in a direct way requires a long time and high cost. Thus, using a method for measuring the soil infiltration in an indirect way instead of direct way for ...
