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...

Tree species, e.g., shallow vs. deep rooting tree have a distinct impact on hydrological properties and pore size distribution of soils. In our study, we determined the soil hydrologic at three forest stands one pasture as reference soils with stagnant water conditions. All sites are located in Wermsdorf Forest, where historical studies demonstrated severe silvicultural problems associated soil...

Abstract The main goal of this research was to conduct a biophysical, economic, social, and perception-based approach foresee the solutions that could be used mitigate soil loss problem cost-effectively in “La Ribera del Xúquer” district (Valencia Region, Spain). To achieve these goals, farmer perception survey carried out, an assessment biophysical impact catch crops on organic matter, bulk de...

It is located on a calcareous hillside facing SSE and composed of nine erosion plots (4 x 20 m). In summer 2003, after eight years of soil and vegetation recovery from previo...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract After pointing out the importance of the saturated hydraulic conductivity (k s) measurements and the difficulties and uncertainties that are present, and after recalling salient aspects of three well-known measurement methods of this param...

Abstrak. Infiltrasi merupakan proses masuknya air ke dalam tanah secara vertikal. Air hujan yang jatuh permukaan akan masuk dan tertampung di selanjutnya mengalir tempat lain lebih rendah apabila pori telah terisi sepenuhnya dengan air, sebagai aliran (runoff). Lubang resapan biopori (LRB) suatu teknik konservasi dapat membantu penyerapan besar sehingga laju infilltrasi menjadi cepat, hal ini d...

The effects of urbanization on soil structure can be extensive. Infiltration of rain water through soils can be greatly reduced, plus the benefits of infiltration and biofiltration devices can be severely jeopardized. Our research group (along with others), have been studying disturbed urban soils for several decades, both in the laboratory and in the field. The effects of compaction on infiltr...

packed gravel that overlies a thin (3–10 cm), fine-grained, gravel-poor, vesicular A (Av) soil horizon.1 Desert paveDesert pavements are prominent features in arid environments ments are prominent features in arid environments and and consist of a surface layer of closely packed gravel that overlies a thin, gravel-poor, vesicular A (Av) soil horizon. Well-developed Av can be found on a variety ...

Slow infiltration rates constrain effective and economical irrigation in some sandy loam soils in California. Polyacrylamide (PAM) has increased soil infiltration in some areas, especially in soils high in clay or silt. Field trials near Fresno, CA, with PAM failed to show improved infiltration. Laboratory experiments were conducted to investigate PAM effect on infiltration of various quality w...
