GG231 Lecture Notes - Lecture 3: River Engineering, Grand River Conservation Authority
Document Summary
What is vulnerability: is considered in the study of flood and vulnerability index as the extent of harm, which can be expected under certain conditions of exposure, susceptibility and resilience. Data shows a relation between the peak discharge of a flood and its average recurrence. Floods peak discharge can be compared at any station along the river can be compared with discharges measured overtime at that station. Formula used to recurrence is r = (n + 1) m. M = the rank of the individual flow within the recorded years. The grand river conservation authority has developed a strategy for a flood warning system. The modification of the stream channel such as straightening or deepening, and often occurs in urban areas where the stream is fitted to the built structures. Putting house or building or stilts main is now the second floor and the 2nd floor is now the 3ird and so on.
