In 1966, "Underground waters flow to the ocean" novel was published after his death.

West Valley is in an area of heavy rainfall that environmentalists say is prone to underground water flow.

However, the process is influenced by underground water flows, causing oil to migrate hundreds of kilometres horizontally or even short distances downward before becoming trapped in a reservoir.

For example, she said, scientists have studied underground water flow for years, which is important to the repository because that is the likely means for radioactive material to spread.

Several authors have suggested that the Pleistocene stone artefacts and megafauna bones may have derived from separate contexts that have become mixed by underground water flow.

Due to an incomplete understanding of the underground water flow in the region, sewage seeped into the cave and drinking water, and the cave became severely polluted.

Wind, rain, birds, animals, and underground water flow can all spread the radioactivity to the Columbia River, which forms one border of the 470-square-mile reservation, and even farther afield.

One of the most notable aspects of this lake is the greenish aspect of its water, caused by limestone sediments being dragged into the lake by the underground water flow.

The level of the lake varies by approximately 4 to 5 meters along with the varying underground water flow during the year, hence reaches its minimum by the end of April when snow melting in the mountains increases.

The flow system has been severely attacked by building the Flims Bypass Tunnel when engineers decided to divert some 800 Litres per minute of underground water flow out of the tunnel instead of sealing it into the rock.

The estimates of how long Yucca can exist without radiation leaks are based on several factors, including how long the metal containers holding the waste would stay intact, and how fast radioactive materials would be carried through the soil by underground water flows.

One lawyer, Geoffrey Fettus of the Natural Resources Defense Council, describing the department's design as a "septic field" in which radioactive particles, carried by rain water into the underground water flows, would spread over a broad area, diluted enough at the border to meet radiation exposure standards.
