Numerical modelling in support of a conceptual model for groundwater flow and geochemical evolution in the southern Outaouais Region, Quebec, Canada [PDF]

, 2017
A two-dimensional vertical-section numerical model for groundwater flow and transport using age, tritium and chloride was used to help validate a conceptual model of geochemical evolution within a representative regional-scale hydrogeological system in ...

Isogeochemical Characterization of Mountain System Recharge Processes in the Sierra Nevada, California

Water Resources Research
Mountain System Recharge processes are significant natural recharge pathways in many arid and semi‐arid mountainous regions. However, Mountain System Recharge processes are often poorly understood and characterized in hydrologic models. Mountains are the

Increasing Groundwater Availability and Seasonal Base Flow Through Agricultural Managed Aquifer Recharge in an Irrigated Basin [PDF]

, 2019
Groundwater aquifers provide an important “insurance” against climate variability. Due to prolonged droughts and/or irrigation demands, groundwater exploitation results in significant groundwater storage depletion.

Developing a preliminary recharge model of the Nile Basin to help interpret GRACE data [PDF]

, 2009
GRACE data provides a new and exciting opportunity to gain a direct and independent measure of water mass variation on a regional scale, but the data must be combined with hydrological modelling to indicate in which part of the water cycle the mass ...

Assessing the Sustainability of Community‐Managed Irrigation Systems Using Multicriteria Analysis and Sustainability Indicators in Northern Ethiopia: A Holistic Approach

Irrigation and Drainage, EarlyView.
ABSTRACT Reservoir‐based irrigation schemes (RBISs) have been developed to minimize the adverse effects of moisture stress and improve the livelihoods of smallholder farmers in semi‐arid regions. However, many RBISs perform below expectations. A multistage expert elicitation approach and an indicator‐based Sustainability Assessment of Food and ...

Constraining recharge and groundwater models with HydEOmex soil moisture observations [PDF]

, 2016
Estimation of groundwater recharge has underpinned a wide variety of groundwater resource and quality assessments within the UK at a range of scales. For example, there are many studies that have quantified time‑varying recharge rates in order to model ...

Transforming Agricultural Water Management Through the Water–Energy–Food Nexus: Trends, Opportunities, Barriers and Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural water management (AWM) is increasingly transitioning towards transformative thinking, where interconnected sectors, including water, energy and food, are managed holistically. Trends point towards cross‐sectoral and harmonised strategies to optimise water use efficiency and productivity, integrate renewable energy, promote ...
