Which of the following combinations of catchment characteristics would most significantly lead to a high peak discharge and a short lag time on a hydrograph?
Question 2
A river catchment experiences a period of intense, localized thunderstorms after several weeks of moderate rainfall. How would the antecedent moisture conditions influence the flood magnitude from these thunderstorms?
Question 3
Which of the following human activities, when implemented on a large scale within a river catchment, is most likely to lead to a decrease in lag time and an increase in peak discharge on a hydrograph?
Question 4
A flood management strategy involves constructing a series of upstream dams and reservoirs. While these structures can regulate flow, under what specific conditions might they paradoxically exacerbate flood risk downstream?
Question 5
A river basin is characterized by a high drainage density. What is the most significant implication of this characteristic for the river's response to a sudden, heavy rainfall event?
