Trees and forests play a central role in watershed hydrologic processes. Inforested watersheds, net precipitation accumulates overtime and infiltrates into the soil, percolating downward to deep groundwater or moving laterally through the soil to a lotic orlentic system. When the soil is completely ...
Figure 14shows a schematic diagram of a mine-waste impoundment. The generation of acidic drainage results from the exposure ofsulfide mineralsin the vadose zone of the tailings impoundment to atmospheric O2. Oxygen penetrates the sulfide-bearing wastes by downward and inward movement. Limiting O2trans...
Regional water and land use changes suggest that ponds and rice fields may contribute significantly to groundwater recharge during the dry season. In the last 35 years, the number of irrigation wells has increased from <100,000 to >1.7 million25primarily to support dry-season irrigation, which ...
In this study, a data-driven approach employed by utilizing the product called JRC-Global surface water mapping layers V1.4 on the Google Earth Engine (GEE) to map and monitor the effects of climate change on surface water resources. Key climatic variabl
rills gush downward, terrace by terrace, channeling the stone rails of the balusters, leaping from step to step, dripping into mossy conches, flashing in spray from the horns of sea-gods and the jaws of mythical monsters, or forcing themselves in irrepressible overflow down the ivy-matted ...
and installations to graphic works are all internally connected. Likewise, similar functions can be obtained through the ingenious use of water surfaces or mirrors. When the water is upward, the sky seems downward in the reflection of mirrors. What’s more, there is also holy water inside the...

Field capacity is the soil water content a few days after the soil has been thoroughly wetted, when downward movement of gravitational water has become very slow. The permanent wilting percentage is the soil water content at which plants remain wilted unless the soil is rewetted. It is obvious...
Downward-facing bulbous load casts of sand are separated by upward-pointing flame structures of mud (Figure 2). Some occur on otherwise flat bedding surfaces, whilst others accentuate erosional or depositional irregularities. In extreme cases, sand may be detached from its source bed and occur as...
