Anatomía De Un Cenote Con El Uso De Dron

Abstract

<p><strong>Background:</strong> Detailed geomorphological analysis of the karst depressions in Yucatán has received little attention because the measurement of morphometric parameters taken in the field involves a lot of work, time and costs. A pioneering exercise is presented that arose with two questions. What would be the characteristics of the relief that can be observed and / or measured in a cenote through images acquired with a drone? Would they be features similar to those seen with Google Earth images? <strong>Objective:</strong> To identify the units of the relief and morphometry of a cenote using images from two different platforms. <strong>Methodology:</strong> An open cenote located in the municipality of Chapab, Yucatán, was studied. A flight was carried out with a drone obtaining 259 images in 14 minutes, with which an orthomosaic, a digital elevation model and a point cloud were generated. We proceeded to the analysis of the data of the visible range (RGB), work with filters in ArcMap; the same spatial analysis procedure was performed with an image from Google Earth. <strong>Results:</strong> Nine units of the relief were identified in detail (permanent lake, intermittent lake, an area subject to flooding, beach, mouth, flooded slope, upper slope, scarp and lake coast); the differences between inputs are mainly in the morphometric parameters and in the values of the elevations. <strong>Implications:</strong> Drones facilitate imaging that allows detailed characterization of karst depressions to represent attributes that cannot be expressed on small scales. <strong>Conclusion</strong>: The anatomy of the Polol cenote technically corresponds to a sinkhole that houses a karst lake; nine relief units were identified that reveal limnological processes generating a karst-lacustrine environment that leads to the geomorphological enrichment of this region.</p>

“…Estos, a su vez, se clasifican por su grado de desarrollo del karst, (Ayuntamiento de Tulum 2021-2024 y Universidad Autónoma del Estado de Quintana Roo, 2023). El término regional de cenote tiene su origen en la lengua maya "dzonot", que significa abismo (Arroyo-Arcos et al, 2019;, utilizado de manera general para referirse a depresiones naturales originadas en la roca y con presencia permanente o estacional de agua (Gijón-Yescas et al, 2021). Constituyen el rasgo topográfico y característico más importante del territorio, distribuidos principalmente en la zona norte (Beddows et al, 2007;Mondragón-Mejía et al, 2019).…”

Past and Present Drivers of Karst Formation of Ciénega de El Mangle, Panama

“…The lack of proper management in karst areas can lead to several issues, such as soil erosion [15,16], aquifer pollution, subsidence [17][18][19], and collapse [12]. Studying karstic depressions is vital for understanding groundwater dynamics and land stability, offering valuable insights into water resource management and geohazard mitigation [20][21][22]. Therefore, detailed knowledge of karstic areas is crucial for the sustainable management and evasion of environmental problems in the future, as well as for the improvement of landscape and land use planning [23][24][25][26].…”
