Groundwater Affects the Geomorphic and Hydrologic Properties of Coevolved Landscapes

David G. Litwin et al.

Summary: This study developed a new model to explore how runoff generation affects long-term catchment evolution, focusing on hydrologic processes dominating in humid climates. The results showed the interplay between surface and subsurface water, with implications on landscape evolution and runoff generation.

Hydrology without dimensions

Amilcare Porporato

Summary: By applying the II theorem and self-similarity hypotheses, this paper explores the partitioning of water and soil on terrestrial landscapes. Through dimensional analysis, the dominant environmental controls and scaling laws for these partitionings are revealed. The study also uncovers the influence of the dryness index and storage index on rainfall partitioning, as well as the existence of macroscopic relations in landscape evolution statistics.

The Function of Boundary Conditions in the Physical Sciences

Julia R. S. Bursten

Summary: The paper discusses the misunderstanding of the function of boundary conditions in early philosophical accounts of explanation and concludes that it still persists. Through case studies in fluid mechanics and wave physics, the author identifies four explanatory functions of boundary conditions in physics, emphasizing their roles in model components.
