To understand how new data may affect the flood-frequency curve, you can follow these steps:
1. Read the articles provided in the links to gain a thorough understanding of the topic. These articles discuss the impact of new data on flood-frequency curves.
2. In the first link, "http://www.atypon-link.com/IAHS/doi/abs/10.1623/hysj.50.2.193.61795?cookieSet=1&journalCode=hysj," you will find a study published in the Hydrological Sciences Journal. This study focuses on the incorporation of new data into flood-frequency analysis and the implications it has on flood risk assessments.
3. The second link, "http://water.usgs.gov/admin/memo/SW/sw77.04.html," directs you to a technical announcement by the U.S. Geological Survey. This announcement discusses updates to the agency's policy regarding the use of new data in establishing flood-frequency curves.
4. Review the key findings and conclusions of these articles. Pay attention to any discussions of how new data can impact flood-frequency curves, such as changes in flood magnitude, recurrence intervals, or uncertainty estimates.
5. Consider the limitations and uncertainties associated with the new data. New data may come with its own set of assumptions, measurement errors, or biases. Understanding these factors is crucial in assessing the reliability and accuracy of the updated flood-frequency curve.
6. Reflect on how the incorporation of new data affects flood-risk assessments and management strategies. With more accurate and up-to-date flood-frequency curves, decision-makers can make more informed decisions regarding flood control measures, land-use planning, and insurance premiums.
By following these steps and studying the provided articles, you can gain a comprehensive understanding of how new data may affect the flood-frequency curve.
