“…Two sets of field measurements were used to address our objectives: (i) pedon‐scale irrigation events on 10‐m by 10‐m plots with hourly measurements of soil VWC, and (ii) small watershed observations of soil VWC over a period of months with bimonthly soil moisture observations in 2008 and 2009 (Dinka et al, 2013). Measurements of VWC were compared with PALMS simulations with the M&M module turned on and off (PALMS matrix only).…”

Core Ideas Time for water to fully drain from cracks and mesopores was 24 to 72 h. In moist, cracked soil, water moved to 60 cm after 2 h. On dry, cracked soil, water moved to >120 cm in <1.5 h. The mesopore infiltration module improved estimation of soil profile water content. At the pedon scale, the mesopore module improved ponding predictions. Water is preferentially conducted away from the soil surface through large cracks formed in shrink–swell soils, which complicates our ability to calculate the partitioning of water into infiltration and runoff. Preferential flow paths affect the hydrology of a landscape but often are not included in hydrology models. The Precision Agricultural‐Landscape Modeling System (PALMS) contains a Mesopore and Matrix (M&M) module that allows preferential flow and was tested on cracking soil at the pedon and small watershed scale for this study. Four irrigation events were conducted on 10‐m by 10‐m plots of a cracking soil, and volumetric water content (VWC) output for PALMS with and without the M&M module was compared with that measured by a neutron moisture meter. Additionally, measurements of VWC on a 4.4‐ha small watershed were compared with PALMS predictions. At both scales, the M&M module simulated water movement down the soil profile more quickly and eliminated unobserved ponding at the pedon scale relative to the PALMS matrix only. Simulations of water content of the soil profile were generally improved when the M&M module was used. Furthermore, PALMS M&M was relatively easy to parameterize using obtainable and physically relevant parameters, rendering it applicable to shrink–swell soils in a variety of systems.

“…These features are indicative of poorly drained soils within a fine-grained floodplain (Aslan and Autin, 1998). Slickensides and pressure faces suggest the occurrence of significant variations in soil water content (Dinka et al, 2013), implying strong seasonal variability with summer drought. Palaeosols displaying seasonal wet-dry cycles cover an area of several square kilometers, which suggests that they are not localized occurrences associated with periodic channel levee breaching.…”

a b s t r a c tThe Vale do Forno archaeological sites (Alpiarça, central Portugal) document the earliest human occupation in the Lower Tejo River, well established in geomorphological and environmental terms, within the Middle Pleistocene. In a staircase of six fluvial terraces, the Palaeolithic sites were found on the T4 terrace (þ24 m, above river bed) which is made of a basal Lower Gravels unit (LG) and an overlying Upper Sands unit (US). Geomorphological mapping, coupled with lithostratigraphy, sedimentology and luminescence dating (quartz-OSL and K-feldspar post-IRIR 290 ) were used in this study. The oldest artefacts found in the LG unit show crude bifacial forms that can be attributed to the Acheulian. In contrast, the US unit has archaeological sites stratigraphically documenting successive phases of an evolved Acheulian. Luminescence dating and correlation with the Marine Isotopic Stages suggest that the LG unit has a probable age of ca. 335 to 325 ka and the US unit an age of ca. 325 to 155 ka. This is in contrast to previous interpretations ascribing this terrace (and lithic industries) to the Last Interglacial and early phases of the Last Glacial. The VF3 site (Milhar os), containing Micoquian (Final Acheulian) industries (with fine and elaborated bifaces), found in a stratigraphic level located between the T4 terrace deposits and a colluvium associated with Late Pleistocene aeolian sands, is younger than 155 ka but much older than 32 ka.© 2016 Elsevier Ltd.

For Western Europe and specifically in Iberia, insights into the Palaeolithic occupation is similarly derived from its major rivers (from north to south: Douro, Tejo/Tagus, Guadiana, Guadalquivir) (e.g. Santonja and Villa, 2006). Within this context, the Vale do Forno archaeological sites (Alpiarça, in central Portugal; Fig. 1) provide the earliest and most well documented human occupation in the Lower Tejo (the Portuguese part of the Tejo basin). Lower Palaeolithic bifacial sites are common, often well represented by lithic industries. Their local stratigraphy and technological characteristics indicate successive phases of what is commonly named as the Acheulian. However, they were chronologically poorly constrained.From the Spanish border to the Atlantic coast, the Tejo crosses major faults which provide a natural geomorphological subdivision of the river into a series of valley reaches (I to V;Cunha et al., 2005). * Corresponding author.E-mail addresses: pcunha@dct.uc.pt (P.P.

A b s t r a c t. The general characteristics: particle size distribution, pH, cation exchange capacity, organic matter content, total NPK, surface area; and physical properties: coefficient of linear extensibility, tensile strength, shear strength and cracking, were investigated in unproductive soils of Northern China. Principle component analysis showed that tensile strength, cohesion, cracking characteristics, clay content, cation exchange capacity and coefficient of linear extensibility were positively correlated with each other, whereas negatively correlated with angle of friction, indicating that these properties were subjected to clay % and smectite content. These correlations might be mainly responsible for low productivity (low yields) in Northern China.
