What are the physical features of boscastle which made the flooding worse?

∙ 11y ago
· Three rivers - Boscastle had three rivers passing through: The Valency, Jordan and Paradise, meet on the village of Boscastle. The Valency caused the majority of the damage. It had three rivers, which increases the chances of flooding.
· Heavy rain-was caused by extreme frontal activity. In total, 3 million tonnes of water was added to a tiny drainage basin, whose size is just 40 square kilometres.
· The soil- was already saturated from previous rainfall earlier in the week, causing the overland flood to start sooner.
· The rain -matched with the high tide in the bay. This limited the rate of exit of floodwater into the harbour.

Boscastle's topography, with steep valley sides and a narrow river channel, contributed to the rapid flow of water during heavy rainfall. The surrounding impermeable slate rock also led to increased surface runoff. Additionally, the village's location at the confluence of three rivers made it more susceptible to flash flooding.

What is the importance of contour plowing?
Contour plowing helps to prevent soil erosion by slowing down the flow of water on sloped land. It also helps to retain water in the soil, improve water infiltration, and minimize runoff, which can reduce the risk of flooding and enhance crop yields.
How did life in the Chang Jiang Valley differ from life in the Huang He Valley?
Life in the Chang Jiang Valley was characterized by more stable and predictable flooding from the river, leading to fertile land for agriculture. In contrast, life in the Huang He Valley was marked by unpredictable and devastating floods, which made agriculture more challenging. The Chang Jiang Valley had a milder climate and more diverse crops, while the Huang He Valley had harsher conditions and relied more on flood control and irrigation systems.

Is the weathering of building in towns worse than in the country?
Yes, the weathering of buildings in towns can be worse than in the country due to higher levels of pollution, moisture, and foot traffic. Towns typically experience more vehicle emissions, industrial pollution, and higher population density, all of which can contribute to faster deterioration of building materials.
Why is salinization worse in some countries?
Salinization can be worse in some countries due to factors such as low rainfall which doesn't leach salts from the soil, poor drainage leading to waterlogging and salt accumulation, and inefficient irrigation practices that deposit salts in the soil. Additionally, human activities like deforestation and improper agricultural practices can exacerbate salinization in certain regions.

Discuss how flooding problems are getting worse with increased development?
Flooding problems are getting worse with increased developement because our lands are very low. As erosion increases, our land diminishes little by little. Over thousands of years the tide has risen and the land has lowered, causing an increase in floods, especially in the coastal regions of the world.

Removal of vegetation and wetlands and the creation of paved roads has increased runoff and decreased transpiration and storage of water in wetlands. As a result flooding becomes worse and more frequent.
