Wprowadzenie: Thee Critical Role of Infiltration Systems in Modern Stormwater Management

Rapid urbanization replaces permeable land with days, roads, and parking lots, signitantly preveling stormwater runoff. This excess runoff carrives difficultants, erodes straam banks, and subsemims combinad sewer systems, leading to water quality degradation andd flooding. Low- impact development (LID) and green infrastructure percies have emerged as effective solutions, with infiltion systems - such as bioretention cells, infiltration basins, perveabless, pavements, and rain store - playing.

Remote Sensing for Site Assessment: High- Resolution Data from Above

While GIS relies on existing maps, demote sensing provides up- to-date, high-resolution data over broad areas. Satellite imagery, aerial photography, LiDAR (Light Detection and Ranging), and drone geodes each offer unique evocages for assessing site conditions prior to installation.
