Abstract:
... The karren formation and karren features of bare slopes is studied. The occurrence of various karren features was measured on slopes with different inclination. The occurrence of various karren features on slopes has been presented according to slope inclination values. The slopes were put into slope categories and their karren features were given. Thus, the karren formation of the bare slopes of ...

Abstract:
... Trees in semi-arid conditions survive despite water scarcity and shallow soils because they commonly have access to subsoil water resources. Currently, conventional models do not include groundwater transpiration and the results frequently underestimate the actual evapotranspiration and overestimate the net recharge. Therefore, in this work we focus on how a multi-variable calibration with a multi ...

The balance structure of the pumpage sourses of riverside water-intakes, developing a subsoil aquifer or intermediate water that hydraulically interacts with it, can show the effect of the processes of water balance adjustment in the unsaturated zone to the accompanying subsoil water level drawdown. In this case, because of the shallow depth to subsoil water, its level drop due to water withdrawal ...

Abstract:
... Most soil functions, such as food production, carbon and nutrient cycling or water regulation and filtration strongly depend on soil structure quality (SSQ). But SSQ is increasingly threatened by compaction, carbon loss and erosion. SSQ should be protected by environmental regulations, however, reliable and easy methods for SSQ assessment are still missing. The aim of this study was to define a cl ...

Eight regional to continental scale datasets providing Cd concentrations in subsoil (C horizon or mineral soil collected at depth) and topsoil are used to compare the statistical distribution of Cd in the two soil layers. Topsoil is invariably enriched in Cd when compared to subsoil. When both horizons are mineral soil the concentration ratio CdTOP/CdSUB is 1.3–2.2. This ratio is substantially lar ...

Subsoil manuring is a practice that involves placing high rates of organic amendments in bands at the base of rip-lines that extend down into the subsoil to a depth of 30–40cm, in order to ameliorate poorly structured clay subsoils. The objective of this study was to determine whether the increases in crop yield from this practice, which occurred at one site in the high-rainfall zone in Victoria f ...

Abstract:
... The heat and mass transfer simulation model of a ground heat exchanger (GHE) directly affects the design and operation performance of a ground-coupled heat pump system. The GHE models based on the response function (like the Green function and g-function) can achieve a fast calculation speed. However, the heat sources in these models are limited to points or whole boreholes, leading to low calcula ...

Effect of soil thermal saturation can be reduced to some extent in longer EATHE pipe but it is uneconomical. In the present study sub-soil moisture content is increased to enhance soil thermal properties an ...

We compared BD (0–120 cm) from hydraulic samples (BD) with soil pit samples (BD) within a corn (, L.)–soybean [ (L.) Merr.] rotation field in central Iowa. Although BD varied substantially compared with BD with RMSE of 0.15 g cm and with increasing soil depth, ...

Abstract:
... Inter-individual variability of tree drought responses within a stand has received little attention. Here we explore whether the spatial variations in soil/subsoil properties assessed through Electrical Resistivity Tomography (ERT) could explain variations in drought response traits among trees. We used ERT to compute the percent variation in resistivity (PVR) between dry and wet conditions as an ...
