Sea Level and Storm Hazards: Past and Present

Sea level and Storm Hazards: Past and Present is a multidisciplinary study of past changes in sea level. Prehistoric shorelines can be used as a baseline for current and future sea level changes under warmer-than-present climate. Emphasis is placed on looking at sea levels during warm periods of the last 500,000 years as well as how base level changes increase the risk of coastal inundation...

Assessing stormwater reduction using green infrastructure: Niagara River Greenway Project (Buffalo, NY)

The effectiveness of green infrastructure (porous asphalt, planter boxes, rain gardens, and the removal of impervious pavements) at reducing stormwater runoff is being assessed at the Niagara Street redevelopment project in Buffalo, New York. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, evapotranspiration, precipitation, and soil moisture.

Streamflow Characteristics and Trends in New Jersey, Water Years 1897 - 2017

Water resource managers regularly utilize streamflow statistics from the USGS for planning and regulation across the state. The impacts of climate, water use, and land use changes can alter streamflow over time. Periodically updated streamflow statistics are essential for the effective management of water resources in New Jersey.

The long-term effects of Hurricanes Wilma and Irma on soil elevation change in Everglades mangrove forests

Mangrove forests in the Florida Everglades (USA) are frequently affected by hurricanes that produce high-velocity winds, storm surge, and extreme rainfall, but also provide sediment subsidies that help mangroves adjust to sea-level rise. The long-term influence of hurricane sediment inputs on soil elevation dynamics in mangrove forests are not...
