Water Resources Research, Volume 61, Issue 9, September 2025.Abstract Beavers (Castor canadensis) alter river corridor hydrology by creating ponds and inundating floodplains, and thereby improving surface water storage. However, the impact of inundation on groundwater, particularly in mountainous alluvial floodplains with permeable gravel/cobble layers overlain by a soil layer, remains uncertain.

Geological modeling of Altavilla Milicia (Sicily) using HVSR data
, 2014 At today the use of inversion of HVSR curves is mainly limited to derive average parameters of the shear wave velocity, although recently they have been used also for a detailed reconstruction of the roof of the seismic bedrock (Di Stefano et al.

Dizhen xuebao, 2020 地球物理反演浅地表土层波速剖面通常基于初始速度结构模型，为避免对地勘资料产生较多依赖，充分利用地震和背景噪声等被动源观测记录，快速简便地构建出土层反演的初始模型，本文基于场地土层的频散曲线和水平与竖向谱比提出了一种改进半波长法。该方法首先通过水平与竖向谱比确定场地土层的卓越频率，获取场地覆盖层厚度，确定反演所需的频带范围；其次，利用瑞雷波相速度对剪切波速的偏导数随土层深度的变化规律反演出场地的初始速度结构，并结合工程场地勘探中的半波长法 ...

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon
Earth and Space Science, Volume 12, Issue 9, September 2025.Abstract One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic ambient noise techniques—including seismic interferometry, H/V spectral ratios ...
