facilities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The geographic positioning of these industrial zones exposes broad land parcels to periodic torrential rainfall and rapid surface water runoff originating from adjacent eastern mountain wadi catchments.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Managing stormwater drainage networks across spread-out industrial

Jeddah Industrial Zones<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The coastal topography of Jeddah features steep inland mountain slopes that drain westward into flat coastal plains before reaching the Red Sea.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During intense seasonal thunderstorm events, surface runoff travels rapidly through dry wadi channels, descending into urban and industrial basins.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As industrial development expands across Jeddah 2nd and 3rd Industrial Cities, natural soil absorption is replaced by impermeable surfaces, such as asphalt logistics yards, concrete foundations, and metal factory roofs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This high proportion of impermeable land cover increases surface runoff volume and accelerates peak flow velocities across primary transport avenues.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Traditional static drainage ditches and underground box culverts frequently struggle to handle unmodeled water surges, leading to localized ponding near high-value manufacturing plants and electrical substations.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To mitigate recurring flood risks, municipal planners and civil engineers require dynamic, high-density elevation models that
