South Australian experience in aquifer storage and recovery

CRC Press eBooks (2020)

N.Z. Gerges P. J. Dillon X. P. Sibenaler R. Russell Martin Paul Pavelic

Aquifer Storage and Recovery (ASR) offers opportunities for both government and the private sector to increase management options for better use and reuse of water resources. It has been used to restore saline aquifers and assist in replacing or enhancing irrigation water supplies. ASR research and development in South Australia has been unique because it has focussed on the injection, storage and recovery of poorer quality water such as stormwater, stream-water and reclaimed water. Investigations are underway that may lead to storage of 14 Mm3/yr of reclaimed water in aquifers underlying the horticulture and viticulture areas north and south of Adelaide. Currently, over 25 ASR projects are in operation, under development or being investigated, with the intention in most cases of using stormwater and/or reclaimed water for irrigation. This paper summarizes some of the activities in South Australia and comments on well construction, clogging, aquifer hydraulics and other related issues.

Measurement of 3‐D Hydraulic Conductivity in Aquifer Cores at In Situ Effective Stresses

Ground Water (2002)

Martin Wright Peter Dillon Paul Pavelic Paul Peter Andrew Nefiodovas

Abstract An innovative and nondestructive method to measure the hydraulic conductivity of drill core samples in horizontal and vertical directions within a triaxial cell has been developed. This has been applied to characterizing anisotropy and heterogeneity of a confined consolidated limestone aquifer. Most of the cores tested were isotropic, but hydraulic conductivity varied considerably and the core samples with lowest values were also the most anisotropic. Hydraulic conductivity decreased with increasing effective stress due to closure of microfractures caused by sampling for all core samples. This demonstrates the importance of replicating in situ effective stresses when measuring hydraulic conductivity of cores of deep aquifers in the laboratory.

Cooperation in hydrogeophysics: Enhancing practitioners and institutions’ groundwater assessment capacity, Vientiane Plain, Lao PDR

Geophysics (2021)

Eddie W. Banks Michael Hatch Somphasith Douangsavanh Paul Pavelic Sounthone Singsoupho

The lowland floodplains of the Lao People’s Democratic Republic (PDR) experience prolonged dry seasons characterized by pronounced and common water scarcity, with water supplies increasingly offset with groundwater. Groundwater assessment is still at a very rudimentary stage in Laos, making it difficult to ensure that new water supplies are developed successfully and managed sustainably. The goal of this study is to apply a variety of field hydrogeophysical techniques to this problem and in the process help build and strengthen human and institutional capacity with various stakeholder groups from the government, the university, and the community. The study area focuses on a cross section of the Vientiane Plain (VP) in the Lower Mekong Basin in central Lao PDR to identify and characterize the hydrogeology and groundwater quality. The research collaboration has built and strengthened stakeholder capacity by developing and progressing the hydrogeologic field mapping of the VP. It has provided local undergraduate and postgraduate training opportunities using several different near-surface geophysical and hydrogeologic techniques, some previously untested in Lao PDR. At one of the survey sites, the geophysics has indicated the spatial extent of the shallow aquifer and in the process identified an extensive conductive zone, interpreted as more saline groundwater. Any groundwater development within this or similar zones is likely to be unsuitable as sources for drinking and irrigation water. Engagement with the local village authorities has supported local community members and government to expand groundwater development for rural water supplies. Access to groundwater as a reliable, safe, and secure resource provides an opportunity for strengthening the resilience of farmers to changing climatic conditions. Participatory research collaboration of this kind can positively enhance data and build capacity, which is a required precursor for improving knowledge and management of poorly understood groundwater resources.

Integrating cost and benefit considerations with supply- and demand-based strategies for basin-scale groundwater management in South-West India

Water International (2012)

Saideepa Kumar L. Surinaidu Paul Pavelic Brian Davidson

Efforts to reverse groundwater depletion in hard-rock regions by enhancing aquifer recharge with valuable surface water present complex challenges and trade-offs related to upstream–downstream interactions and equity. Here, groundwater modelling is used in combination with economic valuation techniques to assess the effectiveness of alternative supply and demand measures under different climate change scenarios in an upper sub-basin of the Krishna River basin in India. It is found that aquifer recharge provides benefits for the sub-basin that are not apparent at the basin scale. Water recharged or crops selected in upper catchments should aim to generate economic benefits that outweigh losses faced downstream.

Management of Ground Water in Africa Including Transboundary Aquifers: Implications for Food Security, Livelihood and Climate Change Adaptation

HAL (Le Centre pour la Communication Scientifique Directe) (2011)

Yvan Altchenko Seleshi Bekele Awulachew Benjamin Brida Hama Arba Diallo Dam Mogbante

Groundwater is one of the most important sources for drinking water, livestock water, and irrigation in Africa. It is of vital importance in meeting the Millennium Development Goals (MDGs) target of accessing clean water, as most of rural Africa and a considerable part of urban Africa are supplied by groundwater. Groundwater also has a major role to play in improving food security through expansion of irrigation supplied by shallow and deep wells. As such, groundwater has high relevance to the development and wellbeing of Africa, if adequately assessed and sustainably exploited. However, impacts of rapid development and climate change on water resources, including groundwater, are expected to be very severe unless major actions are taken to address the limited human and institutional capacity and hydrogeological knowledge base needed to devise sustainable adaptive water management strategies. Whilst the potential for groundwater resources development and the extent of their vulnerability due to climate change in the African context continue to be reported in the literature, a quantitative understanding of these issues remains poor. Although groundwater systems respond to human and climatic changes slowly (relative to surface water systems), climate change still could affect groundwater significantly through changes in groundwater recharge as well as groundwater storage and utilization. These changes result from changes in temperature and precipitation or from change in land use/land cover, and increased demand. There is therefore a need for ensuring sustainability and proper management of groundwater resources through instituting proper aquifer management practices such as the establishment of groundwater monitoring systems, better understanding of the role of groundwater storage and groundwater discharges in sustaining aquatic ecosystems, understanding the interactions between various aquifers (including transboundary aquifers) and assessing the impact of increased pumping from various aquifer systems on the sustainability of groundwater abstraction. This paper provides an overview of the regional hydrogeological framework, the current state of knowledge of aquifer systems, their development potential and climate change impacts on groundwater, research gaps, and policy implications for meeting the MDGs of accessing clean water and livelihood goals in Africa.
