//ilearn.laccd.edu/courses/48546/discussion topics/392408 a t G Google This is a graded discussion: 13 points possible Discussion 4 (Running Water) Unfortunately there are always plenty of recent natural disasters in the news, so let's use them as learning experiences. A short news search should give you plenty of recent information on flood events. I would like you to pick one of these and answer the following. due Jul 1 at 11pm . when and where this event occurred . amount of water/area of geographic region impacted main cause of flood what flood prevention measures and regulations were in place . what main lessons can be learned The last part of this is the most important, as other flood prone regions can hopefully learn from previousExplanation / Answer
Cause of flooding- A deep sub-tropical low brought severe weather, including torrential rain causes flash flood.
RAINFALL- According to Gisborne Council figures, at least 6 locations recorded more than 115 mm of rain in 24 hours on 11 June, including Tuahu (136 mm), Tutamoe Station (126mm), Puketoro Station (122.5mm) and Mata River at Pouturu Bridge (118 mm).The rain continued to fall into 12 June, and by 18:00, many of these areas had recorded a further 60 to 90 mm of rain and Waikura had recorded 125.5mm of rain.
DAMAGES-
100 people evacuated (estimated figure)
Gisborne - June 11 to June 13, 2018
Roads damaged- 20 roads
Gisborne - June 11 to June 13, 2018
Several roads were blocked by flooding, including the highways 2 and 5. The town of Te Karaka in Gisborne was been completely cut off after flooding blocked access
PRECUATIONARY MEASURE- The families evacuated last week were moved out overnight as a precautionary measure and that no families were in the flood zone.
LESSONS-
Concrete is no longer a solution- For centuries flood protection has meant building ever higher walls and radically straightening and clearing rivers, to rush water ever faster to the sea. But a more crowded island, rising sea levels and increasing extreme weather caused by climate change mean the hard engineering approach is hitting its limit.
Flood protection often work- Despite the thousands of homes that have been flooded during this sodden and stormy winter, about a million have been protected by the defences that held out.
