Question

Quizplus · Accepted Answer

Monitoring water levels and evaluating past behavior of a stream are both important factors in predicting floods. By monitoring the current water levels, scientists can determine if the stream is nearing flood stage. By evaluating past behavior, such as how the stream has responded to heavy rainfall in the past, scientists can anticipate how the stream may behave in the future. Therefore, the best choice is D, monitoring water levels and evaluating past behavior for a stream.
