Isophreatic curves of groundwater wells in the upper zone of Cerro de Hula, Santa Ana, Francisco Morazán

Abstract

The research is part of a master's research thesis, the aim of which is the generation of groundwater well curves in Cerro de Hula, located south of the capital of Honduras, which serves as a baseline to understand the movement of groundwater flow in the area preliminarily. To achieve this, groundwater level surveys were carried out in the field in April 2022 (dry season), which were analyzed, processed, and interpolated using the Kriging method in ArcGis software. The main findings show the survey of 21 groundwater extraction points, belonging to shallow and deep wells that supply around 2900 people in the area, and that the preliminary water movement according to the isophreatic curves corresponds to a radial flow, with curves ranging from 5 m deep of the water table remaining in the western part of the area (highest part), and moving downwards to the 100 m deep curves (eastern region). It is conclusive to mention that this is a preliminary tool for managing the area's underground water resources. Keywords: groundwater, water table, isophreatic curves, radial flow.
