A series of remarkable hydrogeological achievements has been carried out by China Geological Survey（CGS）in recent 20 years. A national groundwater resource and related environment investigation project was implemented in plains, basins and the key economic areas from 2000 to 2005. To meet the needs of groundwater supply and ecological protection, the 1:50,000 hydrogeological survey, following standard sheet format, has been launched since 2003. Up to now, a standard combined of field investigation, mapping & database management has been set up, and 600,000 square kilometers has been finished. A new version of 1:50,000 hydrogeological maps have been produced . From 2005 to 2015, National Groundwater Quality and Pollution Investigation, which was implemented by CGS for the first time,covered an area of 4.4 million square kilometers,completed 36000 sets of groundwater samples with 72 testing indicators,and ascertained the current status of baseline groundwater quality involving the inorganic and organic contaminants. From 2015 to 2017, National Groundwater Monitoring Project has been established progressively. The range of this project contains large-scale plains, basins and contiguous karst areas with controlling areas of 3.5 million square kilometers, and the general objective for this project is to construct a comprehensive national groundwater monitoring system, integrated with information collecting, transporting, processing, analyzing and customized servicing. With the aims of summarizing investigation and research results, promoting the theoretical innovation of hydrogeology, engineering geology and environmental geology, CGS is responsible for Atlas of Geological Environment of China,including 8 groundwater maps, such as Map of Groundwater Resources in China(1:5,000,000), Map of Groundwater Environment in China(1:5,000,000), Hydrogeological Map of Chinaetc.

Groundwater Management Downunder – Lessons Learned From the Australian Experience
Martin Søgaard Andersen1,2
1Connected Waters Initiative Research Centre, UNSW, Sydney, Australia
2School of Civil and Environmental Engineering, UNSW, Sydney, Australia
The Murray-Darling river basin is Australia’s largest and economically most important river basin. Much of the basin is located in the arid and semi-arid climatic region of Australia with low and unreliable rainfall. Groundwater therefore plays an important role in securing domestic and agricultural water supplies in parts of the basin and in times of low surface water flows. Due to a combination of droughts and water-overuse the basin has been the cause of much political tension and conflict between various users and interest groups for over almost a century. As a consequence different management and water allocation strategies have been implemented, such as the recent Murray-Darling Basin Plan agreed in 2012. Underlying these strategies has been a desire to base the water management of the basin on a better scientific understanding and quantification of flows and processes, which has spurred much scientific research. This talk will focus on the role of groundwater in the Murray Darling Basin, and in particular the scientific advances in the understanding of groundwater processes in the Basin. The talk will also highlight some of the challenges and research questions still remaining.

Do you know where your catchment ends? The role of inter-basin groundwater flow and hydrogeologic transience in hydrologic processes
David F. Boutt1
1Department of Geosciences,
University of Massachusetts-Amherst, Amherst, MA, USA, 01003
A fundamental concept in the hydrologic analysis of watersheds is that the water draining to the outlet of the basin originates within the basin itself. Groundwater hydrologists have long understood the role and impact of inter-basin groundwater flow, defined here as the subsurface transfer of water across topographic boundaries. This inter-basin transfer of water leaves a distinct impact on the hydrologic and solute budgets of the catchments. This talk addresses when and where topographic catchment divides correspond to groundwater divides and how this is affected by climatic variability and geologic heterogeneity. Examples from a range of climates and geologic environments (northern Chile, Great Basin of the United States, Trinidad and Tobago, and coastal Massachusetts) will highlight the relevance of inter-basin flow on hydrologic and geologic processes. Additionally, the coupling of hydrologic transience and changes in groundwater storage is also discussed, since these two processes are often difficult to separate in practice. Finally, I present recommendations and suggestions for new approaches to conceptualization of hydrogeologic watershed boundaries that take into consideration both geologic uncertainty and climate variability.
Fluid injection induced seismicity: a hydrogeologic perspective
1Department of Geological Sciences,
University of Colorado Boulder, Boulder, Colorado, USA
Frequent seismicity has been occurring in the past decade in tectonically quiescent regions such as the central eastern USA. Studies have identified spatiotemporal associations between the seismicity and deep wastewater injection related to oil and gas production, but many injection sites experienced no seismicity. Although pore pressure change from deep-well injection has been known to be the primary culprit for inducing earthquakes since the 60s, questions remain with regard to hydrogeological and poro-mechanical processes in causing seismicity, as well as what injection operational parameters make some sites more prone than others to induced seismicity. This presentation offers an overview and insights gained from studying fluid injection induced seismicity in recent years from hydrogeological and poro-mechanics perspectives. Case studies are presented to illustrate how pore pressures play a role in inducing observed seismicity. Modeling of pore pressure diffusion suggests that high-rate injections create an intense hydrogeological perturbation to the subsurface system, which emerges as an important factor in contributing to induced seismicity. As pore pressure front propagates from the injection site, it could trigger seismicity as it encounters rock weaknesses such as fractures or faults. Assuming the Earth’s crust is critically stressed, relatively small pore pressure perturbation could trigger seismicity. The spatial extent of pore pressure influence could reach tens of kilometers from high-rate injection wells in a few years. Continuing research to probe interactions among pore pressure propagation, ambient background stress, and spatial distribution of fractures and faults in heterogeneous geologic formations will further advance our understanding on hydrogeological, mechanical, and seismologic processes. Ultimately, these efforts can help provide much needed guidance for best practices and mitigate induced seismic hazard in the quest for energy resources.

Electrical Hydrogeology: A Picture is Worth 1000 Wells
1School of Geology, Oklahoma State University, Stillwater, OK, USA
The science of hydrogeology was developed by creating conceptual models of the subsurface based on chemical or physical hydrogeology principles. Numerical and analytical modeling added significantly to the science to understand how to best sample and test these subsurface ideas. The ability to collect high density electrical data on an academic and commercial basis has allowed us to make several new advancements in the science. This talk will look at how electrical data can allow us to determine the location of flow paths, find meter-scale structures that change our conceptual models, and monitor life in the subsurface as it grows. Examples will include water supply in porous media and karst domains as wells as contaminated sites affected by microbial activity.
Exploring better and new utilizations of groundwater in Korea
1School of Earth and Environmental Sciences,
Seoul National University, Seoul 08826, Korea
Groundwater in some countries has been used as a precious water resource by providing major drinking waters to residents. In some other countries, however, groundwater is being recognized as auxiliary water reserved for severe drought or unexpected and urgent water crisis caused by accidental contamination of the main water reservoirs such as lake or river. Not being utilized as a precious water supply renders groundwater as a poorly managed resource because not much investment is allowed under the economic point of view based on the benefit/cost ratio frame. This in return causes groundwater usage more shifted to be trivial. In order to reverse this negative feedback to positive feedback, finding methods of high-value groundwater utilization are necessary. Here I want to describe several efforts to find ways for good and distinct utilization of groundwater: 1) premium drinkable water through big data analyses, 2) wellbore energy storage and groundwater heat pump, 3) cold water for thermoelectric generator, 4) dual resources of energy and water normally energy source switchable to water supply in case of drought. Groundwater quality data, well hydrogeological data, and time-series observation data in several regions of Korea were analyzed to obtain data structure mapping relevant to the groundwater with premium qualities for specific purposes. Monitoring and analysis data of groundwater heat pump installation and operation are provided with the efficiency of electricity saving. The analysis and discussion about the groundwater heat pump is extended to wellbore energy storage. Thermoelectric generator application by using groundwater is also presented. Possibility of groundwater utilization as renewable energy source in normal time and make it switchable to water supply to cope with drought or water emergency case is discussed.

How Urbanization, Poverty, and Populations are Shaping Asia’s Groundwater Future
Franklin W. SCHWARTZ1
1School of Earth Sciences, The Ohio State University, Columbus, Ohio, USA
Increasingly, groundwater management in Asia can be increasingly characterized as a race to the bottom with more and more pumping for irrigation, chasing less and less groundwater, for example, in Northern China and Western India. Not surprisingly, associated problems of diminished food security, land subsidence and saltwater intrusion in coastal aquifers are also widespread. If there was ever to be progress towards groundwater sustainability in Asia, it should have already started. After all, the theory and tools necessary to manage groundwater sustainably have existed for many years, supported by a variety of successful experiences. For example in Orange County, California, there is aggressive recharge of excess surface water and recycled waste water, and hydraulic barriers working to block saltwater intrusion. In Central Valley, groundwater sources depleted from agricultural irrigation were replaced by imported surface water. For many Asian nations, there are both financial and technical impediments to sustainability. The upfront costs for getting into the sustainability game for groundwater are large. There are informational and infrastructure needs to be met before even starting, e.g., detailed characterization of aquifer systems, and comprehensive monitoring systems. Augmentation of groundwater sources with imported, recycled, or artificially-recharged water is challenged by cost, technical complexity and the inability to capture water from relatively short-lived monsoonal deluges. Locally, water problems of cities, especially megacities, are an emerging concern. A case in point is Jakarta, Indonesia, which exemplifies difficulties rapidly-growing cities are experiencing in managing groundwater sustainably. With a population growth rate of ~4% per year, expected to reach 25 million by 2025, groundwater resources are at substantial risk of depletion and contamination. Elsewhere, large existing populations e.g., China, India and Pakistan reduce the resiliency for coping with stresses to the water resources. If, for example, groundwater scarcities develop, it may be simply infeasible to replace a large existing demand for groundwater. The reality for many nations is that water shortages are not their most serious problems. Crises, stemming from insurgencies and natural disasters, like flooding, earthquakes, and from the need to keep economies growing often demand immediate attention, as compared to the more slowly developing environmental and health problems. Yet, heading off future water supply problems demands immediate concerted action.

Global sustainability with groundwater in Asia
1Research Institute for Humanity and Nature, Kyoto, Japan
Global sustainability depends on groundwater governance in Asia, not only because of large water footprints through global trade of agricultural/industrial materials, but also due to carbon emissions through human activities using groundwater in Asia. On the other hand, sustainable groundwater governance has cultural dependency because of differences in hydroclimate, hydrogeology, water management, and water culture in each area. Historical literacies on hydrogeology show that cultural dependency and strong interactions between humanity and nature can be found in many areas in Asia. They can also tell us how much humanity and nature are closely related to each other in Asia. This interaction is important for finding solutions towards sustainability for the current complicated and wicked global environmental problems. In this keynote speech, global sustainability with groundwater in Asia is overviewed in terms of interdisciplinary and transdisciplinary studies. These studies on hydrogeology are categorized into two types of studies; a) integrated discipline-oriented studies of groundwater as a part of seamless water movement on the earth, such as land-ocean interactions including saltwater intrusion and submarine groundwater discharge, and b) integrated holistic understandings of groundwater with different disciplines and stakeholders. Challenges for the future of hydrogeology towards global sustainability are discussed from the viewpoints of system knowledge, target knowledge, and transformation knowledge. Regarding system knowledge, interactions beyond the nexus including groundwater, and groundwater footprints with sustainability indices are essential as the center of information among nature, society and humanity. Back cast scenarios and future designs are important for target knowledge. Transformation knowledges are related to human behavioral changes and technological innovations. Natural and social tipping points, regime shifts, and resilience are keys for the future of hydrogeology and a sustainable society.
