Home Solutions Water Resources NATURAL RESOURCES Water resources Xcalibur Smart Mapping Towards Sustainable Water Management Water resources detection The sustainable management of water is a global concern due to increasing scarcity and degradation of water resources. Access to clean water and its protection are critical challenges facing society today. Groundwater prospecting, salinity assessment, and pollution evaluation have become fundamental areas of research. Groundwater represents around 30% of the world’s freshwater, while only 1% is found in rivers and lakes. The United Nations includes it in its Sustainable Development Goals towards the 2030 agenda. Aero-geophysics and Remote Sensing offer significant advantages in sustainable water management. These techniques allow for the identification and mapping of aquifers, estimation of their storage capacity, and assessment of their vulnerability to saline intrusion and contamination. They also provide essential information for analyzing groundwater flows, interaction with surface waters, and dynamics of hydrological processes. GEOPHYSICAL METHODS FOR GOUNDWATER EXPLORATION Among the most commonly used geophysical methods are Electromagnetics, including time-domain electromagnetic (TDEM) and frequency-domain electromagnetic (FDEM) methods. TDEM methods involve the transmission of short electromagnetic pulses and provide information about electrical conductivity and subsurface formation geometry. FDEM employs a constant frequency electromagnetic signal to measure subsurface responses. Due to the current situation and the imperative of energy transition, Xcalibur Smart Mapping has developed a solution which incorporates methods for the search for groundwater while also enabling the monitoring of surface variables related to the presence of aquifers in regional studies. REMOTE TECHNOLOGIES FOR WATER RESOURCES Using airborne geophysics and remote sensing technologies to gather information about water bodies, their distribution, quality and dynamics from distance (drones, aircrafts, satellites). Airborne electromagnetic (AEM): Method that uses electromagnetic fields to map the electrical conductivity of the Earth’s subsurface. Airborne Gravimetry: Regional geoid modelling can be used to produce accurate elevation models to enhance flood monitoring and water management. Remote sensing: remote sensors capture data based on the reflection (and emission) of energy from the Earth’s surface. Different surfaces reflect or emit energy across various wavelengths of the electromagnetic spectrum. Remote data can be a valuable tool to monitor large areas, optimize resource use, and improve decision-making for conserving water resources. SURFACE WATER Mapping and monitoring Surface water quality assessment Flood monitoring and management Drought monitoring GROUNDWATER Groundwater mapping High conductivity areas Thickness and depth of aquifers Saltwater intrusion in coastal areas SPECTRAL RESPONSE FOR WATER The spectral response of water refers to how water reflects, absorbs, and transmits electromagnetic energy at different wavelengths of the electromagnetic spectrum. Water’s spectral properties are unique and are used in remote sensing to identify, map, and monitor water bodies, as well as to assess water quality. Visible: Low reflectance. Peak Reflectance in Blue-Green NIR: Strong absorption. Low reflectance: Water bodies appear very dark in NIR imagery SWIR: Higher absorption: Water absorbs almost all energy in this range, making it virtually invisible in SWIR imagery TIR: Water emits thermal radiation depending on its temperature Our projects Groundwater detection Acquifer delineation using the TEMPEST® AEM System DOWNLOAD PDF Contact us FILL THE FORM
