Monitoring the groundwater level in tropical peatland through UAV mapping of soil surface temperature: a pilot study in Tanjung Leban, Indonesia

ABSTRACT There is increasing interest in the use of unmanned aerial vehicles (UAVs) as cost-effective, high-resolution alternatives to satellites for the environmental monitoring of large areas. In this study, we tested the feasibility of using UAV-acquired soil surface temperature to monitor groundwater level in a peatland undergoing groundwater restoration to mitigate fire risk (Tanjung Leban, Indonesia). We used two UAVs (Inspire 1, with an infrared camera, and Phantom 4) to map soil surface temperatures at 459 points on bare land. Using a spline analysis of groundwater-level and elevation data in Arc GIS 10.6, we produced ground elevation and groundwater table maps and measured the groundwater level (depth from the ground surface) at each bare-land point. Spearman’s rank correlation analysis determined a negative correlation between the soil surface temperature and groundwater level. Our study shows that soil surface temperature is a reliable proxy for groundwater level in tropical peatlands. This proxy can be monitored cost-effectively using UAVs equipped with infrared cameras.

The Groundwater Drought Initiative (GDI): Analysing and understanding groundwater drought across Europe

Abstract. In Europe, it is estimated that around 65 % of drinking water is extracted from groundwater. Worryingly, groundwater drought events (defined as below normal groundwater levels) pose a threat to water security. Groundwater droughts are caused by seasonal to multi-seasonal or even multi-annual episodes of meteorological drought during which the drought propagates through the river catchment into the groundwater system by mechanisms of pooling, lagging, and lengthening of the drought signals. Recent European drought events in 2010–2012, 2015 and 2017–2018 exhibited spatial coherence across large areas, thus demonstrating the need for transboundary monitoring and analysis of groundwater level fluctuations. However, such monitoring and analysis of groundwater drought at a pan-European scale is currently lacking, and so represents a gap in drought research as well as in water management capability. To address this gap, the European Groundwater Drought Initiative (GDI), a pan-European collaboration, is undertaking a large-scale data synthesis of European groundwater level data. This is being facilitated by the establishment of a new network to co-ordinate groundwater drought research across Europe. This research will deliver the first assessment of spatio-temporal changes in groundwater drought status from ∼1960 to present, and a series of case studies on groundwater drought impacts in selected temperate and semi-arid environments across Europe. Here, we describe the methods used to undertake the continental-scale status assessment, which are more widely applicable to transboundary or large-scale groundwater level analyses also in regions beyond Europe, thereby enhancing groundwater management decisions and securing water supply.

Spatial analysis of ground water level and fluctuation at regional level in North-East of Haryana: Reference to Karnal District, India

The study was conducted to found the ground water potentials in Karnal district of Haryana with an aerial extent of 2520 sq. km. The study has analysed the spatial-temporal changes in groundwater depth in Karnal district to understand the hydrological behaviour and status of the area. Various thematic maps were prepared such as (Groundwater and its fluctuation of pre-monsoon and monsoon in two decades (1996-2017). The main objective of the study was to investigate the temporal trends in annual and monthly groundwater level with the help of central ground water board data. The result indicate a mix of negative and positive trends in the ground water level series.
