About

Nicholas Pinter is a Professor and Associate Director of the UC Davis Center for Watershed Sciences in the Department of Earth and Planetary Sciences. He earned his Ph.D. from UC Santa Barbara in 1992. His research focuses on earth-surface processes, particularly geomorphology and applied geoscience, with recent work involving rivers, fluvial geomorphology, flood hydrology, floodplains, and flood-related public policy. Pinter's group applies tools such as fluvial geomorphology, hydrologic and statistical methods, GIS, and other approaches to assess river dynamics and flood hazards. Although much of his current research centers on rivers and flooding, he continues to study a broad range of processes that shape the earth surface, especially over anthropogenic time scales. A significant aspect of his work involves managing risk from natural hazards, where his team has worked extensively on quantifying risks, guiding mitigation efforts, and providing scientific foundations for natural-hazards policy.

• Managing the Sundhnúkagígar–Grindavík volcanic emergency in Iceland, 2023–2026

  articleOpen access1st authorCorresponding

  After eight centuries of relative quiet, a cycle of episodic volcanic activity began on Iceland’s Reykjanes Peninsula in 2021. In late 2023, the eruption sequence began threatening the Blue Lagoon tourist center, Svartsengi geothermal power plant, and the town of Grindavík. Grindavík’s 3790 residents were evacuated on Nov. 10–11, 2023, and most remain displaced more than 28 months later. Damage to date has resulted from surface deformation, fissuring, and lava flows, but has been limited. Most damage was prevented by construction of lava barriers that today stretch 14 km long and reach up to 25 m high. The most sweeping response to this disaster has been the social safety net provided for the displaced residents of Grindavík, including the buyout of over 950 residences (> 90%) in the town by Þórkatla, a government-chartered corporation. Safeguarding the town and caring for residents have been Iceland’s spotlight political challenge for the past >2 years. Þórkatla’s buyouts in Grindavík began as a short-term humanitarian program, but the long duration of this volcanic sequence and the continued uncertainty are growing challenges to the original vision. Iceland’s investment in this disaster currently exceeds $1.0 billion US dollars, or about 2.6% of its annual GDP. This total, proportional to Iceland’s size, is larger than most other world disasters. The adage that “Civilization exists by geological consent” is nowhere truer than in Iceland, and Grindavík residents and Icelandic leaders find themselves balancing the short time scale of human impacts with long-term geological hazards.

• Exploring International Freshwater Ecosystem Management Strategies for New Perspectives: the Noce River, Italy and Yuba River, California, USA

  2026-03-14

  articleOpen access

  We compared freshwater ecosystem management of the Yuba River, in California, USA, and the Noce River in the Province of Trento, Italy to examine how cultural and political practices can shape freshwater ecosystem management strategies within similar geographical and hydrologic contexts. Specifically, we compared climate, land-use history, flow regulation, restoration approaches, and associated challenges and successes. The Yuba and Noce catchments both have Mediterranean climates, runoff sourced by rainfall and glacial or snowmelt, and developed water supply resources for agriculture, municipal water supply, recreation, and power generation. Both rivers have long histories of human modification, including damming in the 20th century to accommodate escalating energy demand and intensive agriculture. Dam releases for power generation on the Noce River result in hydropeaking, altering the eco-morphodynamics and limiting biodiversity. Water supply storage, diversion for agricultural use, and gravel extraction on the Yuba River results in highly altered flow regimes and degraded instream habitat. Contrasts between the rivers’ respective regulatory frameworks and their intended goals yield different management actions. In the Yuba, the US Endangered Species Act drives targeted restoration for species-specific recovery, limiting broader holistic protections for the aquatic ecosystem. Whereas in the Noce, the European Union Water Framework Directive mandates broad ecosystem benchmarks be met, with restoration focused on improving habitat, biodiversity, and water quality. However, the top-down approach may limit stakeholder involvement. Recently, success in coalition building among California water managers, academic institutions, conservation groups, and private landowners has led to reconnecting floodplain habitats and providing environmental flows for native salmonids. Implementing alternative hydropower generation schemes in the Noce has led to improved aquatic biodiversity metrics and increased recreation opportunities. As climate change exacerbates impacted river functions worldwide, comparison of freshwater ecosystem management between international catchments offers potential new solutions for sustaining essential ecosystem services.

• Shared Challenges, Divergent Solutions: Groundwater Management in California and Catalonia

  2025-03-15

  preprintOpen accessSenior author

  Sustainable groundwater management is critical in semi-arid regions, where competing demands from agricultural, urban, and industrial sectors strain water resources. California and Catalonia share a Mediterranean climate, where the peak growing season coincides with the driest months, necessitating significant reliance on stored water for irrigating agriculture. Here, we examine the science-policy interface in groundwater management by comparing Catalonia, Spain, and California's Central Valley—regions possessing similar climatic pressures but having developed distinct regulatory frameworks under differing hydrogeological contexts.California's Central Valley is characterized by a vast, deep sedimentary aquifer system that supports the largest agricultural economy in the United States. However, over-extraction has led to domestic and agricultural wells running dry, severe land subsidence, and widespread nitrate contamination. In contrast, Catalonia's aquifers are generally smaller, shallower, and are more susceptible to saltwater intrusion from the ocean. In 2014, California passed the Sustainable Groundwater Management Act (SGMA), representing a shift towards regulated groundwater use. However, the state’s complex water rights system—featuring separate allocation frameworks for groundwater and surface water—combined with the immense scale of the Central Valley Aquifer system, complicates the effective implementation of SGMA and its goal of sustainable groundwater management. Conversely, Catalonia, guided by the EU Water Framework Directive of 2000, has adopted an integrated approach to groundwater and surface water management within a unified framework that emphasizes public supply and sustainability.We analyze the contrasting approaches of these two regions to explore what each can learn from the other’s management strategies. For California, Catalonia highlights the importance of treating groundwater and surface water as a single, interconnected resource within a unified regulatory framework. This demonstrates how conjunctive water regulation can improve long-term resource sustainability. Conversely, California’s extensive monitoring networks, basin characterization programs, and advancements in data collection offer valuable tools that could enhance Catalonia’s water management efforts. By focusing on these lessons, we aim to underscore how shared insights can inform more effective water governance in distinct hydrogeological and regulatory contexts.This comparative analysis highlights the critical role of understanding the hydrogeological context in shaping blue diplomacy policies. It underscores the importance of interdisciplinary approaches, such as leveraging diplomatic tools and scientific expertise to address water security challenges and build resilience to climate extremes in semi-arid regions globally.

• A “Parallel Evolution” of Flood Risk Management along the Rhine and the Sacramento Rivers

  2024-03-09

  preprintOpen access

  The Sacramento River in California, USA, and the Rhine River in Europe both have histories of major flooding events and great efforts to manage flood risk. We compare these two watersheds with an interdisciplinary lens to explore the goals, approaches, outcomes, and “parallel evolution” of differing flood risk management paradigms.The two basins share hydrologic similarities, but each approach to managing floods reflects the basin’s unique historical, environmental, and governance context. The Sacramento basin is entirely within the state of California, whereas the Rhine is a transnational river that drains nine European countries. The Rhine basin is larger and has a much larger population compared with the Sacramento basin.  The Sacramento basin has high interannual precipitation variability and receives most of its precipitation in the winter with significant mountain snowfall. The hydrology of the Rhine is also strongly influenced by mountain snowpack, but has precipitation that is more evenly distributed throughout the year. Flood-risk management on both the Sacramento and Rhine Rivers has evolved from ad hoc and local approaches, towards more systematic planning, culminating in significant state-level control in California, and state, federal, and transnational management on the Rhine. This transition was driven in recent years by the Central Valley Flood Protection Act and the European Floods Directive.Management of each basin has been shaped by an event-based evolution, in which disasters have driven management responses, tools, and approaches. Flood-risk paradigms in both basins include significant investment in engineering protection and, increasingly, soft-policy adaptations. Over time, flood management methods and objectives in each basin have become more diverse. For example, single-objective approaches have evolved towards multi-benefit projects. Both basins are expanding consideration of floodplain ecosystem importance and both now consider climate change to some in flood risk management.  Flood-protection levels are higher on the Rhine than on the Sacramento. Some areas of the Rhine have 1000-year or better protection whereas a  200-year-level protection for urban areas is now required in the Sacramento basin.The Sacramento River and the Rhine River are geographically and hydrologically similar in surprisingly many ways, including in the flood risk they pose.  But the flood-risk management paradigms in the two basins have evolved differently.  We argue that the differences are a form of “parallel evolution,” reflecting historical and political contrasts between the two systems.  Such contrasts present opportunities for alternative tools and lessons that can be explored and perhaps imported in both directions.
