similar fractured rock formations elsewhere. One possible means for obtaining such estimates is the use of The search for a permanent storage facility for the geological distension infiltrometers. posal of high-level nuclear waste has motivated extensive research Tension infiltrometers have long been used in soil hyduring the past several decades to characterize and predict fluid flow into and ...

in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.

Prediction of soil characteristics over large areas is desirable for environmental modeling. In arid environments, soil characteristics often show strong ecological connectivity with natural vegetation, specifically biomass and/or canopy cover, suggesting that the soil characteristics may be predicted from vegetation data. The objective of this study was to predict soil infiltration characteris...

The knowledge of the soil saturated hydraulic conductivity (Ks) is essential for irrigation management purposes and for hydrological modelling. Several attempts have been done to estimate Ks in base of a number of soil parameters. However, a reliable enough model for qualitative Ks estimation based on the expert assessment of field characteristics had not been developed up to date. Five field c...

Changes in land use the Air Dingin watershed (DAS) area Padang City, Indonesia, lead to a decrease rainwater infiltration volume ground. Some Latung sub-watershed capacity with an increase surface runoff. This research aims determine effect of land-use changes on and Purposive sampling method was used this research. The measured directly field using double-ring infiltrometer, data processed Hor...

This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

The stability of a rock slope is strongly influenced by the pattern groundwater flow through fracture system, which may lead to an increase in water pressure partly open joints and consequent decrease wall strength. comprehension challenging but vital aspect engineering geology since fractures’ spatial distribution, connectivity, aperture guide both movement quantity within volume. In literatur...
