Abstract. A major concern in groundwater exploration is to determine a precise location of the groundwater resources. The geospatial technology such as UAV mapping, precise GPS surveying and GIS data management could be integrated with other geospatial information to augment the groundwater exploration. The aim of this research project is to support groundwater exploration at UTM, Johor Bahru campus by employing the geospatial approach. In doing so, the aerial photo captured by using UAV and GPS will be utilised to support geology and geophysics data collection. Subsequently, subsurface information such as lithology, stratigraphy and geological structures have been used to form the subsurface profile. Afterward, development of the groundwater geospatial database had commenced by using a GIS approach. It is expected that by integration of geospatial technology in groundwater exploration works will help to identify the location of potential groundwater zone in the study area.

Groundwater research has evolved tremendously as presently it is the need of society. Remote Sensing (RS) and Geographical Information System (GIS) are the main methods in finding the potential zones for the groundwater. They help in assessing, exploring, monitoring and conserving groundwater resources. A case study was conducted to find the groundwater potential zones in Lingasugur taluk, Raichur District, Karnataka State, India. Ten thematic maps were prepared for the study area such as geology, hydrogeomorphology, land use/ land cover, soil type, NDVI, NDWI, slope map, lineament density, rainfall and drainage density. A weighted overlay superimposed method was used after converting all the thematic maps in raster format. Thus from analysis, the classes in groundwater potential were made as very good, moderate, poor and very poor zones covering an area of 10.1 sq.km., 169.25 sq.km., 1732.31 sq.km. and 53.66 sq.km. respectively. By taking the present study into consideration, the future plans for urbanization, recharge structures and groundwater exploration sites can be decided.

The Chuetsu earthquake restoration and revival support geographic information system (GIS) project was launched after the 2004 Chuetsu earthquake. It was the first project to gather disaster GIS data at one place, and provide them by Web GIS from off–site of the disaster site in Japan. To facilitate sharing disaster geospatial information, we introduced a framework of Geography Network as GIS portal. The GIS portal was based on loosely–coupled system architecture. Therefore, it was able to change the system structure by system requirement of the project. The GIS portal was used continuously and commonly for the 2005 Fukuoka Earthquake and 2005–2006 Heavy Snow Disaster and the 2007 Chuetsu-Oki Earthquake. In this paper, we define the system requirement to share disaster geospatial information by knowledge from case studies, and describe a practical method to build the framework, demonstrate the benefit from the framework.

Abstract Coastal areas worldwide are often densely populated and host regional agricultural and industrial hubs. Strict water quality requirements for agricultural, industrial and domestic use are often not satisfied by surface waters in coastal areas and consequently lead to over-exploitation of local fresh groundwater resources. Additional pressure by both climate change and population growth further intensifies the upcoming water stress and raise the urgency to search for new fresh water sources. In recent years, offshore fresh groundwater reserves have been identified as such a potential water source. In this study, we quantify, for the first time, the global volume of offshore fresh groundwater in unconsolidated coastal aquifers and show that it is a viable option as additional fresh water source in coastal areas. Our results confirm previously reported widespread presence of offshore fresh groundwater along the global coastline. Furthermore, we find that these reserves are likely non-renewable as they were deposited during glacial periods when sea levels were substantially lower compared to current sea level. We estimate the total offshore fresh groundwater volume in unconsolidated coastal aquifers to be approximately 1.06 ± 0.2 million km³, which is roughly three times more than estimated previously and about 10% of all terrestrial fresh groundwater. With extensive active and inactive offshore oil pumping present in areas of large offshore fresh groundwater reserves, they could be considered for temporary fresh groundwater exploration as part of a transition to sustainable water use in coastal areas on the long run.

Industry of geospatial information requires a proper standard which can adapt the user requirements in parallel with the technological improvements over time. Geospatial database is an essential end product that can be used as an input to the Decision Support System. The aforementioned important role can be defined as a main indicator for effectiveness and efficiency of the provision of geospatial data and information. Standard is fundamental especially in a situation where there are so many available technologies and infrastructures on the market. Defining a robust and reliable standard and mechanism to derive the geospatial database is a main key for the successful production of the national geospatial database. NoSQL databases use a different approach to represent the storing mechanism which is generally in a form of relational structured tables. The main difference is related with the flexible model, component and storing mechanism which must not be structured in a tabular and relational way. This paper discusses geospatial database standards by using the NoSQL approach that will be implemented in order to adopt the Indonesian Geographic Feature Catalogues. The implementation of the standard in an operational stage of the geodatabase production can provide the alternative solution in competition with the traditional Relational Data Base Management System approach. Especially in the era of big data and crowd sourcing with a lot of variety in the data structure nowadays, NoSQL raises as an alternative solution to accommodate and utilize its advantages in an applicative way but still selective for the portrayal purposes.

Production Characteristics

A regional geoelectrical survey of a semiarid development area of about [Formula: see text], approximately 300 km NNE of Windhoek, has indicated a quadripartite subdivision of the Kalahari sediments of late Cretaceous to Tertiary age, with a variable development due to considerable undulations of the Damara basement. The Karroo formations are apparently less well represented. A two‐fold interpretative procedure, in which an in itial semiqualitative interpretation involving total longitudinal conductance forms the basis for a subsequent quantitative interpretation, has made it possible to map confidently the major lithological units despite the dearth of reliable stratigraphic control. By relating the geoelectrical data to the groundwater head levels, the degree of penetration and production characteristics of boreholes, and the chemical analyses of water samples, the calcareous sands and sandstones of presumed Middle Kalahari age have been seen to constitute the major aquifer in terms of higher sustained yields of good quality water. Encouraging correlations have been noted between these same production characteristics and the geoelectrically derived thickness, resistivity and transverse resistance of this aquifer. It has therefore been possible to delineate the most promising areas for future groundwater development. The Dar Zarrouk parameters form the basis of a suggested procedure for optimizing the initial stages of groundwater exploration in similar arid and semiarid regions where there is a general absence of lithostratigraphic information.

Abstract Groundwater has become an important source of water to meet the increasing requirement for domestic, industrial, and agricultural needs. The study was formulated to assess the availability of groundwater resources in Selangor State, Malaysia. An integrated MIKE SHE and MIKE 11-based surface water–groundwater interaction model was developed to fulfill the study objectives. Model results illustrated that groundwater flows from the eastern part of the hilly region to the western part and ultimately discharges into the sea. The study also revealed that Sungai Langat, Sungai Klang, and Sungai Selangor receive water from groundwater and do not feed the groundwater. Approximate potential groundwater resources based on water balance study varies from 860–960 million liter per day (MLD), 630–690 MLD, 810–870 MLD to 630–690 MLD for Langat basin, Klang basin, Selangor basin, and Bernam basin, respectively. Impacts due to extreme dry condition showed that groundwater table declined about 0.5–3 m in most of the area. However, groundwater level for the major portion of Selangor State will drop to about 0–1 m for increased abstraction due to changed land-use pattern. Study findings may be used for a holistic and comprehensive management of groundwater resources for sustainable development in Selangor State, Malaysia.
