How landscape change causes flooding in towns and cities
‘In all the industrial countries, rivers have suffered from forest clearance in the uplands, farm drainage in the lowlands and water-proofing in urban areas. Forest clearance took place on the hills, in the valleys and on the plains. This accelerated water runoff. Ploughing and drainage took place in agricultural areas. This accelerated water runoff. River channels were deepened, widened, straightened and fixed. This accelerated water runoff. Large new urban areas were rendered partially impervious, with roofing and paving materials. This accelerated water runoff. The capacity of washlands and flood plains to accommodate peak volumes was diminished by building upon them. Accelerated water runoff raised flood peaks. It then became necessary to place urban rivers into underground culverts or concrete canals, or to supplement their capacity with ‘flood relief channels’. Flooding in urban environments can lead to widespread property damage and even disturb sewage systems. Homeowners may require sewage damage cleanup services to help with the restoration of affected homes. The net effect of all the changes was a dramatic increase in peak storm discharge. Embankments had to be built to prevent overtopping by floodwater. When these works are viewed together it is clear that they do not constitute a good use of public or private expenditure.’ (Tom Turner Landscape planning and environmental impact design 2nd edition 1998 p.294)
It seems that many people struggle with floods, due to the aforementioned reasons. If your property ever becomes flooded or suffers any damage from flood waters, you might want to look into something like ServiceMaster Restoration by Zaba to get things fixed as soon as possible. These floods can destroy the foundations of your home, as well as cause excessive rain damage to parts of your home, such as the roof. Sometimes in adverse weather conditions like flooding, trees can fall over, also posing a large risk to homeowners’ roofing. It is possible to fix a damaged roof though and specialists in roof repair (such as this roofing company: beemerkangaroof.com/service-areas/spartanburg-roofing-contractor/) can be called out in emergencies when damages are severe. Flooding can also cause damage to internal features, such as your home furnace and if that is damaged you will need specialist help to restore it. Working with experts like Buric Heating and Air Condition (www.burichvac.com/beltsville-heating-furnace/) will help homeowners who are discovering issues that have been created by rising water levels. Everybody knows how devastating floods can be. The good news, though, is that landscape architects can offer an ecological and economical solution to the flooding problem in villages, towns, cities and other urban areas: water should be detained and infiltrated. Collectively, these policies can be described as Urban Surface Water Management, Sustainable Urban Drainage Systems and Water Sensitive Urban and Landscape Design.
