Compound Coastal, Fluvial, and Pluvial Flooding During Historical Hurricane Events in the Sabine–Neches Estuary, Texas

چکیده
Abstract When storm surge, river discharge, and rainfall occur simultaneously or in succession, they may cause compound flooding exacerbate impacts coastal communities. In traditional modeling approaches, these driving processes are simulated separately, leading to discrepancies between observed data highlighting the need for coupled frameworks. Here, we develop a coastal–fluvial–pluvial model Sabine–Neches Estuary southeastern Texas using Delft3D simulate flood extent depth during Hurricanes Rita, Ike, Harvey. For each hurricane, four scenarios (i.e., coastal, fluvial, pluvial, compound) modeled determine relative contribution of force water levels across domain. Our results reveal that tropical cyclones such as Harvey accompanied by extended periods produce largest longest duration flooding. Such storms also highly dynamic evolving patterns over their duration, with multiple peaks can inhibit response recovery efforts. simulating storms, provide substantial improvements coastal‐, fluvial‐, pluvial‐only models, decreasing root mean square error 69%, 79%, respectively. contrast, short‐duration moderate severe surge less extensive flooding, which is typically dominated coastal–pluvial interactions. further highlight potential at locations critical infrastructure assets, suggesting adaptation approaches robust types

An analysis of the combined consequences of pluvial and fluvial flooding.
Intense rainfall in urban areas often generates both pluvial flooding due to the limited capacity of drainage systems, as well as fluvial flooding caused by deluges from river channels. The concurrence of pluvial and fluvial flooding can aggravate their (individual) potential damages. To analyse the impact caused by individual and composite type of flooding, the SIPSON/UIM model, an integrated ...

In the summer of 2001, an intense thunderstorm in southeastern Caspian Sea triggered a catastrophic flood in the Madarsoo basin . Use of methods including high-resolution aerial photographs and satellite images interpretation, multi-date mapping, hydraulic calculations and field observations made possible the documentation of the geomorphic impacts on the Madarsoo River and its tributaries.

متن کاملRapid Communication Contribution of relative sea-level rise to historical hurricane flooding in New York City
Flooding during hurricanes is a hazard for New York City. Flood height is determined by storm surge characteristics, timing (high or low tide) and relative sea-level (RSL) change. The contribution from these factors is estimated for seven historical hurricanes (1788–2012) that caused flooding in New York City. Measurements from The Battery tide gauge and historical accounts are supplemented wit...
متن کاملFlooding the Vote : Hurricane Katrina and Voter Participation in New
To what extent did the extensive flooding caused by Hurricane Katrina affect voter participation in the 2006 mayoral election? This article uses voting record data from 20 election cycles, GIS-coded flood-depth data, and census data to examine the voting behavior of registered voters in New Orleans before and after Hurricane Katrina. We use a variety of statistical techniques, primarily propens...
