The National Atmospheric and Oceanic Administration (NOAA) calculates the surge probability distribution along the coast from their long-term tidal stations. This process is sufficient for predicting the surge from common storms but tends to underestimate large surges. Across 23 long-term tidal stations along the East Coast of the United States, 100-year surges were observed 49 times, although they should have occurred only 23 times. We hypothesize that these 100-year surges are not the tail outcome from common storms but are actually caused by major hurricanes. Matching these 100-year surges with major hurricanes revealed that major hurricanes caused 43 of the 49 surges. We consequently suggest a revised approach to estimating the surge probability distribution. We used tidal data to estimate the probability of common surges but analyzed major hurricane surges separately, using the return rate of major hurricanes and the observed surge from each major hurricane to predict hurricane surges. The revision reveals that expected coastal flooding damage is higher than we thought, especially in the southeast United States.

 Storm surges associated with severe cyclonic storms are common occurrences along the east coast of India. The coastal districts of Andhra Pradesh have experienced major surges in the past. Storm surges and the rains associated with cyclones are major causes for coastal flooding in this region. An attempt has been made, in this paper, to simulate surges along the Andhra coast that would have occurred due to severe cyclones during 1891-1996. Inland inundation due to surges is also estimated by using an empirical formula. The computed results are validated with the available observations. The comparison using post-storm survey reports, appears reasonably good to assert that the model is capable of predicting the peak surge amplitude and its location. Frequency of occurrence relationships is obtained for various zones along the coastal region for the purpose of risk analysis.

Abstract. This paper provides a comparison of the causes, effects and aftermaths of the coastal flooding that occurred on the east coast of England in 1953 and the west coast of France in 2010 that resulted in 307 and 47 deaths respectively. The causes of both events are strikingly similar. Both were caused by a combination of high tides, low atmospheric pressure, high winds and the failure of poorly maintained flood defences. In both cases the number of deaths was related to the vulnerability of the buildings and people. Buildings in the flood zones were often single storey bungalows and the people who died were mostly over 60 yr of age. Both tragedies were national disasters. The 1953 flood in England acted as a catalyst for an acceleration in flood risk management policy and practice. It resulted in: the development of a Storm Tide Warning System for the east coast of England; the setting of new design standards for coastal flood defences; increased investment in improving coastal defences; and a substantial new research effort into coastal processes, protection and forecasting. In France there has also been an episodic shift in flood risk management policy with the focus falling on: control of urban developments in areas at risk of flooding; improved coastal forecasting and warning; strengthening of flood defences; and developing a "culture of risk awareness". This paper outlines the lessons that can be learnt from the two events and provides recommendations concerning how future loss of life as a result of coastal flooding can be reduced.

Abstract. To improve our understanding of the influence of tropical cyclones (TCs) on coastal flooding, the relationships between storm surge and TC characteristics are analyzed for the east coast of the United States. Using observational data, the statistical dependencies of storm surge on TCs are examined for these characteristics: distance from TC center, TC intensity, track path angle, and propagation speed. Statistically significant but weak linear correlations are found for nearly all sites. At each location, storm surge is influenced differently by these characteristics, with some locations more strongly influenced by TC intensity and others by the distance from the TC center. The correlation for individual and combined TC characteristics increases when conditional sorting is applied to isolate strong TCs close to a location, though the fraction of surge variance explained is never greater than 60 %. The probabilities of TCs generating surge exceeding specific return levels (RLs) are then analyzed for TCs that pass within 500 km of a location, where between 7 % and 26 % of TCs were found to cause surge exceeding the 0.5-yr RL. If only the closest and strongest TCs are considered, the percentage of TCs that generate surge exceeding the 0.5-yr RL is between 30 % and 50 % at sites north of Sewell’s Point, VA, and over 70 % at almost all sites south of Charleston, SC. Overall, this analysis demonstrates that no single TC characteristic dictates how much surge will be generated and offers a unique perspective on surge probabilities that is based on all TCs rather than focusing only on those that cause extreme surge.

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.

Large areas of North Island hill country are producing below potential as a result of low fertility and poor pasture composition. Removal of undesirable species and replacement with a higher producing pasture is essential for increased productivity but is difficult to achieve. A development programme is described where the use of glyphosate in close association with oversowing and stock management has allowed rapid pasture establishment, marked increase in carrying capacity and a quick return on investment. Keywords: Pasture establishment, glyphosate, oversowing, white clover, subdivision, productivity.

Lincoln Park

In late September 2018, multiple generations of Chicago’s storied social movements marched through Chicago’s Lincoln Park neighborhood as part of the sold-out, three-day Young Lords Fiftieth Anniversary Symposium hosted by DePaul University—an institution that, alongside Mayor Richard J. Daley’s administration, had played a sizeable role in transforming Lincoln Park into a neighborhood “primed for development.” Students, activists, and community members—from throughout Chicago, the Midwest, the East Coast, and even as far as Texas—converged to celebrate the history of Puerto Ricans in Chicago, the legacies of the Young Lords, and the promises and possibilities of resistance. As Elaine Brown, former chairwoman and minister of information for the Black Panther Party, told participants in the second day’s opening plenary, the struggle against racism, poverty, and gentrification and for self-determination and the general empowerment of marginalized people is a protracted one. “You have living legends among you,” Brown insisted, inviting us to associate as equals with the Young Lords members in our midst. Her plea encapsulated the ethos of that weekend’s celebrations: “If we want to be free, let us live the light of the Lords.”
