3 hari yang lalu · There are two major methods for controlling ground water including exclusion technique (Figure 1a) and pumping technique (Figure 1b). Figure 1a: Ground water control in excavations by exclusion. Figure 1b: Ground water control in excavations by pumping. Figure 2: Controlling Ground Water in Shafts.
3 hari yang lalu · Abstract. A substantial carbon (C) debt has been accrued due to long-term cropping for global food production emitting carbon dioxide from soil. However, the factors regulating the persistence of soil organic C (SOC) remain unclear, with this hindering our ability to develop effective land management strategies to sequester organic C in soil. Using a Ferralsol from semi-arid subtropical ...

Since the spatial distribution of soils is required for mapping soil erosion risk, soil erosion locations were mapped using SAS Planet images (Fig. 1).Each soil erosion event was mapped as a point feature based on the interpretation image, and all watershed areas and appropriate spatial distribution of soil erosion were properly considered.
2 hari yang lalu · In areas where erosion control or ground stabilization is required, Geocells are an excellent solution. A geocell for erosion is a cellular confinement system designed to secure soil and prevent erosion. These cells interlock to form a flexible, absorbent, and durable structure that confines and stabilizes the soil.
