Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise
Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Specific yield (SY) is a key parameter in estimating groundwater storage change. Accurately predicting SY in unconfined aquifers remains challenging, as SY varies with groundwater‐level fluctuations and unsaturated‐zone moisture fluxes. This challenge is particularly evident in the North China Plain (NCP), which has experienced substantial ...

Presidential Extra‐Territorialization: How Presidents Go Abroad to Bypass Domestic Constraint
Presidential Studies Quarterly, Volume 56, Issue 1, March 2026.ABSTRACT This paper introduces the concept of presidential extra‐territorialization—the process whereby presidents act through or within a foreign jurisdiction in order to achieve a policy goal which implicates the rights commonly held by US citizens or residents.

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Understanding the mixing of groundwater age and of nonpoint source (NPS) pollutants in water samples is crucial for interpreting age tracer and NPS pollutant data from production wells. Traditionally, diffusion and mechanical dispersion have been key mixing processes embedded in physical models for simulating and interpreting age tracer and ...

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Seepage boundary conditions are commonly used in groundwater simulations to allow groundwater to discharge at the upper surface of the model when groundwater head exceeds atmospheric pressure. However, the extent and transient behavior of the seepage zone are often unknown a priori and difficult to predict.
