“…Table 3 summarizes the simulation scenarios. Based on Zarriello et al (2012), flow discharges corresponding to the 50, 100, and 500 years were estimated as 196, 250, and 424 m 3 /s, respectively at the USGS Gauge 01116500 in Cranston.…”

“…The flow hydrographs produced by HEC-HMS were applied as the upstream boundary conditions. For the steady-state cases, the peak discharge or the computed discharge for specific return periods (Zarriello, Ahearn, & Levin, 2012) were applied. The downstream boundary condition was the stage hydrograph that was extracted from NOAA database at a nearby station in Narraganset Bay: NOAA Providence Station 8454000.…”

“…Here, we discuss how changes in extreme precipitation, and consequently in flood flow discharges, will result in a large uncertainty in the prediction of the 100-year flood event which is a basis for determination of flood zones. The 100-year flow discharge at the USGS 01116500 was 188 m 3 /s until 2009, and was was increased to 250 m 3 /s after the 2010 event (Zarriello et al, 2012). There is an additional uncertainty in the extreme value analysis as the peak flow data usually do not exactly follow a generalized extreme value distribution curve.…”

“…Therefore, confidence intervals are reported for the peak discharge values corresponding to various return periods. For the 100-year event, the lower and upper 95% confidence limits are reported as 180 and 680 m 3 /s, respectively (Zarriello et al, 2012). The upper confidence limit is more than twice the mean value.…”

In March 2010, a sequence of three major rainfall events in New England (United States) led to a record-breaking flooding event in the Pawtuxet River Watershed with a peak flow discharge of about 500-year return period. After development of hydrological and hydraulic models, a number of factors that played important roles in the impact of this flooding and other extreme events including river structures (reservoirs, historical textile mill dams, and bridges) were investigated. These factors are currently omitted within risk assessments tools such as flood insurance rate maps. Some management strategies that should be considered for future flood risk mitigation were modeled and discussed. Furthermore, to better understand possible future risks in a warmer climate, another extreme flood event was simulated. The synthetic/hypothetical storm (Hurricane Rhody with two landfalls) was created based on the characteristics of the historical hurricanes that severely impacted this region in the past. It was shown that while the first landfall of this hurricane did not lead to significant flood risk, the second landfall could generate more rain and flooding equivalent to a 500-year event. Results and the methodology of this study can be used to better understand and assess future flood risk in similar watersheds.

Table 1 shows catastrophic loss by cause for about two decades in the United States (1996-2016 1). Losses of 91.9% were caused by weather-related events including tornadoes, hurricanes, and winter storms in which flooding has a significant contribution. Previous studies indicated that the risk of riverine flooding is increasing due to climate change

The STORMTOOLS Coastal Environmental Risk Index (CERI) has historically been used to assess the damage to residential and commercial structures from coastal flooding, including the effects of sea level rise (SLR) in RI. In the present study, CERI was extended to address the impact of flooding for 100 yr storm, including the effects of SLR, to the newly renovated Warren, RI wastewater treatment facilities (WWTF), located on the tidal Warren River, using FEMA HAZUS damage curves. The analysis shows that the average damage for 100 yr flooding, across all components of the facility, increases with sea level from 16% (0 ft SLR), 23% (2 ft SLR), 26% (3 ft SLR), to 28% (5 ft SLR). The primary settling and chlorination tanks are at most risk and the aeration and reaction tanks at least risk. In an effort to validate the FEMA HAZUS WWTF damage curves, CERI was applied to predict flood damage during the 3 day, March/April 2010 flooding event (500 yr) to the Cranston, Warwick, and West Warwick WWTF located on the Pawtuxet River, RI. The predictions of the damage to each WWTF from this event were compared to observations of the damage made by the plant operators. The percent damage was estimated by comparing the cost of the damage to the assessed value of the facility. Using the FEMA HAZUS damage curves for the observed level of inundation (7 to 8 ft) predicted that the Warwick and West Warwick facility damage ranged from 15 to 45% with an average value of about 30%. The Cranston WWTF damage was very low (<1%) because of the elevation of the facility. The observed damage for the 2010 flood event was approximately 21% for the Warwick facility and 18% for the West Warwick facility, between the FEMA HAZUS lower and average values. Damage to the Cranston facility was consistent between FEMA HAZUS and observed values at <1%.
