Questions and Answers List

level questions: Hard vs Soft Engineering [Done]

QuestionAnswer
What is Hard Engineering?-This is simply Man-Made Structures that Control the Rivers Essentially
What is Soft Engineering?-This is using the River Knowledge to Reduce the Effects of Flooding and making Plans as well
What is a Dam and a Reservoir?-Dams are simply a Barrier that is Built across the River, usually found in the Upper Course -Reservoir happens as a Result of the Barrier, and is simply a Lake behind the Dam -This is an Example of a Hard Engineering
Advantages and Disadvantages of using a Dam and a Reservoir?A: Reservoirs allow the Storage of Water, allows to Control the Flow of Water and can generate Hydroelectric Power to be Generated D: Has a Huge Price Tag with it, Reservoir may lead to Existing Settlements being Flooded, Material being Deposited in the Reservoir and not Downstream meaning the Land may be less Fertile
What is Channel Straightening?-This is simply Removing Meanders by making Straighter Channels -This is an Example of Hard Engineering
Advantages and Disadvantages of Channel Straightening?A: Water leaves Faster meaning the Flood Risk can go Down D: Downstream may experience Flooding, as the Increased Discharge will Quickly go Down There, More Erosion may also happen from the Increased Velocity
What is Embankments?-This is simply Rising the River Banks, that's it -This is an Example of Hard Engineering
Advantages and Disadvantages of Embankments?A: River holding more Water makes Flooding less Likely D: Expensive, and can have a Massive Catastrophe if the Water goes Above the Embankments Level
What are Flood Relief Channels?-This is making Channels to Divert the Water from Wherever they were going, or to simply have it Empty, and then Flood it if the Flood Risk is High -This is an Example of Hard Engineering
Advantages and Disadvantages of Flood Relief Channels?A: Water can be Controlled due to the Gates on the Channel - Water is Controlled D: The Discharge will simply Increase when the Relief Channel joins the River, so Flooding may happen in that Area
What are Flood Warning and Preparation?-This is having Flood Warning being Announced through the use of the Internet, and People -Buildings are Changed [Adapted] to Minimise the Damage -Households can Prepare Sandbags and Flood Boards to help the Fight against Flooding -This is an Example of Soft Engineering
Advantages and Disadvantages of Flood Warnings and Preparation?A: This gives People Time to move their Possessions Upstairs or even Evacuate, reducing the Damage that the Flood will Cause D: This does Nothing to Prevent Floods. Some People may not even be Able to access the Warnings. Making the Buildings more Protected is Expensive and People may be Shocked from a False Sense of Security [Their House will be in Ruins even with Protection]
What are Flood Plain Zoning?-This is simply Restricting Construction on the Flood Plain that has a High Chance of being Flooded
Advantages and Disadvantage of Flood Plain Zoning?A: Flood Risk becomes much lower as Impermeable Surfaces aren't Created meaning the Surface Run Off is Much lower, and the Impacts of Flooding is Lower as Buildings isn't Present D: Urban Areas on a Flood plain make this Concept Completely Useless, and even then, Expanding onto a Flood Plain may be to Sustain Population Growth [Urbanisation]
What is the Advantages and Disadvantages of Planting Trees?A: Flood Risk and Discharge falls, as Trees use Water. Soil Erosion becomes less Common as Vegetation and Trees keep it Up [No Soil = More Impermeable] D: Land becomes Limited for Farming -This is the most Easiest Solution really
What is River Restoration?-This is making the River more Natural- Removing Man Made Structures. This means the Flood Plains are Flooded Naturally
Advantages and Disadvantages of River Restoration?A: Discharge is Reduced meaning Flooding becomes Uncommon down the Stream. Not much Point to Look After, as its just Nature playing the Game and also Wildlife is more Supported D: Flood Risk Locally Increases, Especially if Nothing is Done
