This book was released on 2016-06-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarises the main results of many contributions from researchers worldwide who have used the water infiltration process to characterize soil in the field. Determining soil hydrodynamic properties is essential to interpret and simulate the hydrological processes of economic and environmental interest. This book can be used as a guide to soil hydraulic characterization and in addition it gives a complete description of the treated techniques, including an outline of the most significant research results, with the main points that still needing development and improvement.

This book was released on 2016 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accurate estimation of saturated hydraulic conductivity (Ks) is of high relevance to correctly reproduce water movement in hydrological simulations. Yet, estimation of Ks is challenging particularly in semi-arid regions with particular soil surface characteristics like crusting and sealing. This study presents results of a field campaign in the semi-arid Walnut Gulch Experimental Watershed, Arizona (US), where surface and subsurface Ks measurements were undertaken across the watershed. Results reveal that the following commonly-used assumptions used in estimation of Ks are not plausible in such regions: (i) Ks decreases with increasing soil depth, (ii) soils with coarse-grained texture (sandy loam) have higher surface Ks values compared to relatively fine-grained texture (fine sandy loam), and (iii) pedo-transfer functions are not reliable methods of estimating Ks. Our results also reveal that remote sensing data can provide useful information for estimation of surface and subsurface Ks values.

Available in PDF, EPUB and Kindle. Book excerpt: Methods for measuring saturated hydraulic conductivity (Ksat) of soils are standardized, but the regulations governing the percolation test vary considerably among states. The objectives of this paper are to present an overview of selected procedures for measuring Ksat, and to compare Ksat obtained by the constant-head well permeameter method with percolation rate values for different conditions. Three different models for calculating Ksat were compared and the Glover solution was selected for comparison with percolation rate. Using various hole diameters (2r) and depths of water in the hole (H), different flow rates were used to calculate a Ksat value and a percolation rate for each r and H combination. In general, the relationship between percolation rate and Ksat obtained from the rate of water flow from a given hole is logarithmic. However, this relationship is not unique and depends on r and H. for any given Ksat value, percolation rate increases linearly with increasing r. As a result, for a given soil, different values of percolation rate can be obtained by changing the radius of the test-hole and the required depth of water in the hole within a given set of regulations. For designing septic systems, the percolation test must be standardized or Ksat measurements be used for determining and/or confirming loading rates.
