Geotextiles can either enhance or restrict groundwater flow depending on their permeability and installation method. Permeable geotextiles can allow water to infiltrate through them, facilitating groundwater recharge and promoting natural drainage. Conversely, impermeable geotextiles can prevent water from passing through, altering the natural flow of groundwater and potentially causing waterlogging or surface runoff issues. The selection and proper installation of geotextiles are crucial to ensure they positively impact groundwater flow and maintain the hydrological balance of an area.
Geotextiles can have both positive and negative effects on groundwater flow. When properly installed, they can act as a barrier, reducing the infiltration of surface water into the groundwater system. This can help in controlling erosion and preventing contamination of the groundwater. However, if geotextiles are not installed correctly or become clogged with sediment over time, they may impede the natural flow of groundwater, causing water to accumulate and potentially leading to localized flooding or the alteration of natural recharge patterns. Therefore, the impact of geotextiles on groundwater flow depends on their design, installation, and maintenance.
