The paper deals with measurements of water infiltration carried out on a well-developed forest floor formed by needle-leaf litter Norway spruce. Three field methods (tension disk permeameter, single-ring infiltrometer and Guelph permeameter) were used to determine the soil hydraulic conductivity. results strongly influenced repellency at interface between O- A-horizons. This was severely repell...

Abstract The determination of soil hydraulic properties is important in several environmental sciences but may be expensive and time consuming. Therefore, during the last decades, a great effort has been made to develop relatively easy, robust, inexpensive methods for characterization. In this manuscript, we reviewed discussed different infiltrometer techniques light available experimental appl...

Abstract The land load in the Air Dingin Sub-watershed is increasing due to relocation of Padang City administrative center district. Subsequently, this not only reduces catchment area but also increases surface runoff, because open green space, which originally served as a area, has been converted into settlements. A random measurement infiltration rate with double-ring infiltrometer was used ...

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

A wetting soil water characteristic curve (SWCC w ) is necessary for understanding and interpreting the re-distribution of infiltrated rainwater, percolation rate, contaminant transport. Direct determination SWCC tedious needs destructive sampling invasive sensor installation. This study demonstrates an indirect method determining based on infiltration measurements using a mini disc infiltromet...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

A key parameter for the design of soil drainage and irrigation facilities modelling surface runoff erosion phenomena in land-formed areas is saturated hydraulic conductivity (Ks). There are many methods determining its value. In situ laboratory measurements commonly regarded as most accurate direct methods; however, they costly time-consuming. Alternatives can be found increasingly popular mode...

In the hydrological watershed, some natural processes take place in which interaction of water, soil, climate and vegetation favors capture water. The present study aimed to evaluate preliminary information regarding response water balance a small research watershed with tropical forest cover (15°01'44''N 92°13'55''W, 471 m, 2.3 has). Events precipitation, direct runoff, infiltration rate basef...
