Hydrological modelling for assessing spatio‐temporal groundwater recharge variations in the water‐stressed Amathole Water Supply System, Eastern Cape, South Africa
; Eley, Malte; Schöniger, Matthias; Gwapedza, David; Tanner, Jane; Mantel, Sukhmani Kaur; Scheihing, Konstantin (Hydrological Processes, 2021-06-23)
Abstract To increase the resilience of regional water supply systems in South Africa in the face of anticipated climatic changes and a constant increase in water demand, water supply sources require diversification. Many ... -
Hyper-Resolution Continental-Scale 3-D Aquifer Parameterization for Groundwater Modeling
; ; Maxwell, Reed (Water Resources Research, 2020)
Groundwater is the world's most important freshwater resource. Despite this importance, groundwater flow and interactions between groundwater and other parts of the hydrological cycle are often neglected or simplified in ... -
Identification of groundwater mean transit times of precipitation and riverbank infiltration by two-component lumped parameter models
; ; ; ; ; ; (Hydrological Processes, 2019)
Groundwater transit time is an essential hydrologic metric for groundwater resources management. However, especially in tropical environments, studies on the transit time distribution (TTD) of groundwater infiltration and ... -
Importance of Spatial Resolution in Global Groundwater Modeling
; ; ; ; ; (Groundwater, 2020)
Global-scale gradient-based groundwater models are a new endeavor for hydrologists who wish to improve global hydrological models (GHMs). In particular, the integration of such groundwater models into GHMs improves the ... -
Improved understanding of dynamic water and mass budgets of high‐alpine karst systems obtained from studying a well‐defined catchment area
; Goeppert, Nadine; Goldscheider, Nico (Hydrological Processes, 2021-04-29)
Large areas of Europe, especially in the Alps, are covered by carbonate rocks and in many alpine regions, karst springs are important sources for drinking water supply. Because of their high variability and heterogeneity, ... -
Monte Carlo Simulations as a Decision Support to Interpret δ15N Values of Nitrate in Groundwater
; ; (Groundwater, 2019)
Intense farming is often associated with the excessive use of manure or fertilizers and the subsequent deterioration of the groundwater quality in many aquifers worldwide. Stable isotopes of dissolved nitrate (δ15N and ... -
Use of Stable and Radioactive Isotopes and Gaseous Tracers for Estimating Groundwater Recharge, Time of Residence, Mixing of the Different Types of Groundwater and Origin in the Silao Romita Aquifer, Guanajuato, Central Mexico
(Freiberg Online Geosciences; Vol. 17.2006)Sogenannte Multi-Tracer-Studien sind eine effektive Methode um die Fließbedingungen von Grund- wässern zu bestimmen. Stabile und radioaktive Isotope sowie gasförmige Spurenstoffe wurden zu- sammen mit wasserchemischen ... -
Using Thermal Springs to Quantify Deep Groundwater Flow and Its Thermal Footprint in the Alps and a Comparison With North American Orogens
; Winter, Theis; ; ; ; (Geophysical Research Letters, 2020-11-21)
Deep groundwater flow in mountain belts and its thermal effects are uncertain. Here, we use a new database of discharge, temperature, and composition of thermal springs in the Alps to estimate the extent of deep groundwater ...
