In spite of trying to understand processes in the same spatial domain, the catchment
hydrology and water quality scientific communities are relatively disconnected and so are …

A quantitative description of water flow and solute transport in the unsaturated zone of the
soil is required to predict the impact of human influences on the environment. This paper …

The time water spends travelling subsurface through a catchment to the stream network (ie
the catchment water transit time) fundamentally describes the storage, flow pathway …

A new method is proposed to simulate groundwater age directly, by use of an advection‐
dispersion transport equation with a distributed zero‐order source of unit (1) strength …

The hydrologic response of a channel network is defined by decomposing the process of
runoff formation into two distinct contributions, one accounting for the mechanisms of travel …

The multivariate Gaussian random function model is commonly used in stochastic
hydrogeology to model spatial variability of log-conductivity. The multi-Gaussian model is …

Groundwater Age is the first book of its kind that incorporates and synthesizes the state-of-
the-art knowledge about the business of groundwater dating-including historical …

This paper discusses the results of numerical analysis of dispersion of passive solutes in two‐
dimensional heterogeneous porous formations. Statistics of flow and transport variables, the …

A Lagrangian framework is used for analysing reactive solute transport by a steady random
velocity field, which is associated with flow through a heterogeneous porous formation. The …

Breakthrough curves of a conservative tracer in a heterogeneous two‐dimensional aquifer
are analyzed by means of their temporal moments. The average velocity and the …
