Claim: These tidal floods are often just a foot or two deep, but they can stop traffic, swamp basements, damage cars, kill lawns and forests, and poison wells with salt.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The area is prone to winter floods of fresh water and occasional salt water inundations, the worst of which in recorded history was the Bristol Channel floods of 1607, which resulted in the drowning of an estimated 2,000 or more people, with houses and villages swept away, an estimated 200 square miles (520 km2) of farmland inundated and livestock destroyed.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Wells with water tables that mixed with tributaries (or the non-tidal Thames) faced such pollution with the widespread installation of the flush toilet in the 1850s.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Coastal salt marshes can be distinguished from terrestrial habitats by the daily tidal flow that occurs and continuously floods the area.

Passage: High salt marsh Arrow-grass (forb) panne Briefly flooded, very shallow with a moderate amount of vegetation usually dominated by Arrow grass (Triglochin maritimum), with the deeper sections possibly remaining unvegetated.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Contaminants can enter a water source naturally through flooding.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, or the volume of water leaving an estuary at Ebb tide.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Lack of capacity, or poorly planned or executed drainage or grading of the surface can cause problems after severe storms or heavy extended periods of rain fall, such as flooding, washout, mud flows, sink holes, accelerated erosion, wet rot to wood elements, drowning of plants trees and shrubs and even foundation problems to an adjacent home like cracking the foundation, basement flooding due to water infiltration, pest infiltration like ants and other insects entering through damaged areas.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Flood tide is the rising tide of an ocean, the opposite of ebb tide

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Fatalities connected directly to floods are usually caused by drowning; the waters in a flood are very deep and have strong currents.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Close to of land have been submerged.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In addition to causing water erosion and pollution, surface runoff in urban areas is a primary cause of urban flooding, which can result in property damage, damp and mold in basements, and street flooding.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The two notable floods are the following :
