Higher emissions scenarios lead to more extreme flooding in the …
网页2024年1月3日 · To better understand the role of seasonal climate drivers in driving flood extremes, we investigate the seasonality of annual maximum discharge occurrence, given the good performance of our ...
Floods: Things to Know | U.S. Geological Survey - USGS.gov
网页2018年6月8日 · Stream stage (or water level) and streamflow (or discharge) are measured at locations called streamflow gaging stations, or, streamgages. Stage is measured and recorded continuously by electronic instruments to an accuracy of 0.01 foot.
Floods and Recurrence Intervals | U.S. Geological Survey - USGS.gov
网页2018年6月11日 · Climate variability (dry cycles to wet cycles) and land-use change play a significant role, but there is a large amount of uncertainty around the flood quantile estimates (the value of discharge corresponding to the 100-year flood), particularly if there isn’t a long record of observed data at a stream location.
The Coupling Effect of Flood Discharge and Storm Surge on
网页2021年6月2日 · The flood discharge events last over 10 days and dominate the extreme flood stages of waterways in the middle and upper PRD, and dramatically escalate the low tide levels and reduce the tidal range at the Hengmen outlet. In contrast, the storm surges only last a few hours but dominate the extreme flood stages near the estuary waterway.
Extreme flooding controlled by stream network organization and flow …
网页2023年3月30日 · Limited observational data from very high-magnitude flood events hinders prediction efforts and the identification of discharge thresholds marking the rise of progressively larger floods,...
Climate change impact on flood and extreme precipitation
网页2020年8月13日 · Results show an intensification of extreme precipitation and flood events over all climate regions which increases as water availability increases from dry to wet regions.
Future climate change predicted to shift flood-generating …
网页12 小时之前 · Future flood projections based on climate scenarios suggest a region-wide intensification of flooding (i.e., greater peak discharge). Importantly, the anticipated shift in the Upper Basin's ...
Research progress on the impact of flood discharge atomization …
网页2021年5月18日 · Researchers have found that the water temperature downstream of a dam is affected by flood discharge (Habets et al. 2018). After the reservoir is built, the water depth of the waterbody increases, the flow rate decreases, and the water temperature structure of the reservoir changes significantly.
Measuring Flood Discharge | Oxford Research Encyclopedia of …
网页With a continuous global increase in flood frequency and intensity, there is an immediate need for new science-based solutions for flood mitigation, resilience, and adaptation that can be quickly deployed in any flood-prone area. An integral part of these solutions is the availability of river discharge measurements delivered in real time with ...
Flood Frequency Reports | U.S. Geological Survey - USGS.gov
网页2021年2月16日 · Flood-frequency analysis provides information about the magnitude and frequency of floods based on records of annual maximum instantaneous peak discharges. Accurate flood-frequency estimates, created using consistent and uniformly applied methods, are a key component of any effective flood risk and management program.
