The map to the right shows a flood map for the City of York, including the floodplain for a 1 in 100-year flood (dark blue), the predicted floodplain for a 1 in 1000 year flood (light blue) and low-lying areas in need of flood defence (purple). The most sustainable way of reducing risk is to prevent further development in flood-prone areas and ...
Ohio produces three billion dollars worth of natural gas and $844 million of oil annually. Coal deposits were first recognized in the 1740s by early settlers and were mapped as early as 1752. Decreased demand due to increased natural gas production has reduced coal mining in the 2010s, although one underground mine and three surface mines ...
A floodplain or flood plain or bottomlands [1] is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. [2] The soils usually consist of clays, silts, sands, and gravels deposited during floods. [3]

Floodplain restoration can also increase biodiversity by creating new or restoring degraded habitat and encourage growth of native species. [7] [8] Methods of wetland restoration in the floodplain, can help better water quality. [9] Reconnecting rivers to their floodplains promotes carbon storage in soil and regulates processes within soil. [8]
River erosion can be driven by tectonic uplift, climate, or potentially both mechanisms. It is difficult in many areas, however, to decisively pinpoint whether tectonism or climate change can individually drive tectonic uplift, enhanced erosion, and therefore terrace formation. In many cases, simplifying the geologic issue to tectonic-driven vs ...
The process is often a result of a sudden fall in sea level or the rise of land. The disturbance enables a rise in the river's gravitational potential energy change per unit distance, increasing its riverbed erosion rate. The erosion occurs as a result of the river adjusting to its new base level. [1]
Southern Ohio was in for a slight − and temporary − shake on Monday afternoon, when a 3.3 magnitude earthquake hit the area. The U.S. Geological Survey reported that the seismic event occurred ...
