Potential for Increased Inundation in Flood-Prone Regions of Southeast Florida in Response to Climate and Sea-Level Changes in Broward County, Florida, 2060–69

The U.S. Geological Survey, in cooperation with Broward County Environmental Planning and Resilience Division, has developed county-scale and local-scale groundwater/surface-water models to study the potential for increased inundation and flooding in eastern Broward County that are due to changes in future climate and sea-level rise. The purpose is to provide information that can be used to...

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...

Reconstructing Ocean Circulation & Hydroclimate in the Subtropical Atlantic

Changes in rainfall patterns as a result of anthropogenic climate change are already having large ecological and socioeconomic impacts across the globe. Increases in flood damage, wildfire damage, and agricultural losses can all be attributed to anomalous rainfall events and prolonged droughts across the United States in recent years. Additionally, Atlantic Ocean circulation, which has a large...

Actual Evapotranspiration for Florida

Evapotranspiration is a large component of the Florida water budget – generally second only to rainfall, but exceeding rainfall and all other components during droughts. The prominence of evapotranspiration highlights the need to accurately quantify this hydrologic component in quantitative analyses of watershed hydrology.  Spatio-temporal estimates of evapotranspiration throughout Florida are...

Reference and Potential Evapotranspiration

Evapotranspiration can be computed as reference, potential, or actual evapotranspiration.   Reference evapotranspiration is that from a grass surface that is well-watered.  Potential evapotranspiration is that from a surface that has unlimited water (such as a lake). 

Reference and potential evapotranspiration are computed at a 2-kilometer spatial resolution and daily timestep for the...
