UMass Amherst Hydrologist Charts New England’s Aquatic Future: Anticipates Amplified Flooding and Extended Dry Spells


# New England Is Experiencing Warming at a Faster Rate Than the Rest of the U.S., and Alterations in the Water Cycle are Essential for Grasping Future Implications

Climate change is altering ecosystems worldwide, with various regions encountering significant environmental hurdles, though certain areas are witnessing swift changes that surpass others. New England, located in the northeastern United States, is warming more rapidly on average than any other part of the nation. This increase in temperature over the last few decades has resulted in alterations in weather patterns, leading to disturbances such as intense rainfall and prolonged dry periods.

A major consequence of these alterations is their effect on the region’s “water budget”—a complex system that regulates how water is absorbed, circulated, and stored within the environment. Understanding these water dynamics is crucial for anticipating and preparing for future devastating events like droughts and floods, along with their repercussions for ecosystems and human infrastructure.

With a recent grant of $498,999 from the United States Geological Survey (USGS), **David Boutt**, a scholar at the University of Massachusetts Amherst, is spearheading innovative research on how climate change influences the water cycle in New England. Over the next three years, Boutt, alongside his research team and collaborators from various institutions, will develop advanced hydrologic models aimed at predicting the effects that future climate scenarios could impose on the region’s water systems.

## Climate Change’s Intensifying Influence: Three Decades of Observable Changes

“We’re 30–40 years into significant shifts in New England’s climate,” states Boutt, who leads the research within the Department of Earth, Geographic and Climate Sciences at UMass Amherst. During this period, there are now clear indicators that the region’s environment has undergone considerable transformations in its natural hydrologic systems.

Boutt highlights important findings that indicate changes in the water budget, such as:
– **Elevated water tables:** Groundwater levels have been rising throughout much of New England.
– **Greater storm severity:** Rainstorms are becoming more aggressive and unpredictable, frequently overwhelming rivers and urban infrastructures.
– **Variability in drought patterns:** The length, frequency, and timing of droughts have altered, presenting new challenges for water management and planning.

Traditionally, New England has been seen as a region abundant in natural water resources, leading many to believe it would be relatively insulated from the severe droughts and water shortages affecting drier regions in the United States. Nevertheless, research indicates that climate change not only promotes warmer conditions but also brings about more extreme weather patterns—manifesting as both heavy rainfall and enduring dry spells.

## Spotlight on New England: Addressing an Increasing Demand for Research

Research on hydrology in the United States has mainly concentrated on the arid western regions where water scarcity and droughts pose immediate threats. However, the severe floods that impacted Vermont, Western Massachusetts, and other parts of New England in recent years served as a stark reminder of the notable vulnerabilities this region also faces. In light of these escalating challenges, the USGS has intensified its support for research in New England, and Boutt’s study will add to this initiative.

The research project, titled **”Identifying Climate Drivers of Water-Cycle Changes in the U.S. Northeast and Their Impact on Evapotranspiration, Groundwater Recharge Patterns, and Groundwater-Surface Water Connectivity,”** is one of several key initiatives backed by the USGS’s New England Water Cycle Center. This project will address a variety of water-related concerns from **snowmelt and erosion** to **algal blooms**—an extensive approach aimed at delivering a thorough understanding of the region’s hydrologic future.

## Tri-Phase Strategy: Monitoring, Analyzing, and Modeling Water Systems

Boutt and his team will delve into a wide range of research subjects through a three-phase strategy, integrating historical data, isotopic water analysis, and advanced modeling techniques.

### 1. Historical Data Evaluation of New England’s Water Cycle

The initial phase of the project will involve researchers scrutinizing **historical hydrological datasets** compiled over many years. Collaboration between the USGS and Massachusetts state agencies has generated an exceptional data archive, including records of **rainfall, groundwater levels, streamflow**, and beyond. Massachusetts owns one of the nation’s most thorough and longstanding environmental record sets—presenting researchers with a distinctive view of how the water system has reacted to previous changes, such as storm outflows or seasonal droughts.

In recent times, data collection techniques have progressed significantly, with water levels now measured every 15 minutes instead of the more conventional manual monthly recordings. This reduction in measurement interval permits hydrologists to accurately trace how short-lived weather occurrences affect the broader hydrological framework.

### 2. Stable Isotope Examination to Identify Water Sources

In the second phase, Boutt’s team will utilize **stable isotope analysis**, enabling researchers to “fingerprint”
