Abstract Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify
molecular movements and chemical reactions governing groundwater recharge, quality …

The separation of storm hydrographs using stable isotope tracers dates back to the late
1960s. These studies ushered in a paradigm shift in how hydrologists conceptualized runoff …

Understanding the relative influence of catchment structure (topography and topology),
underlying geology, and vegetation on runoff response is key to interpreting catchment …

The Export Coefficient Model (ECM) has been widely used to estimate non-point source
(NPS) pollution loads for its ease of application. The model uses an export coefficient …

Subsurface runoff dominates the hydrology of many steep humid regions, and yet the basic
elements of water collection, storage, and discharge are still poorly understood at the …

Phosphorus and nitrogen pollutions from agricultural non-point source put heavy burden on
water environment. Total nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH 3 …

The effect of bedrock permeability and underlying catchment boundaries on stream base
flow mean transit time (MTT) and MTT scaling relationships in headwater catchments is …

This study aimed to investigate the seasonal variability of runoff generation processes, the
sources of stream water, and the controls on the contribution of event water to streamflow for …

The heavy rain event of July 2018 and Typhoon Hagibis in October 2019 caused severe
flash flood disasters in numerous parts of western and eastern Japan. Flash floods need to …

How does hillslope structure (eg, hillslope shape and permeability variation) regulate its
hydro‐geochemical functioning (flow paths, solute export, chemical weathering)? Numerical …
