Drainage Systems
Definition
Drainage Systems refer to the network of natural or man-made channels that collect and convey surface water across landscapes. These systems include rivers, streams, ditches, culverts, and stormwater infrastructure. In GIS, drainage systems are modeled to understand water flow, manage runoff, and prevent flooding in both rural and urban environments.
Application
Urban planners design stormwater systems based on drainage modeling. Engineers analyze culvert placement and capacity. GIS helps simulate overland flow paths and integrates drainage systems with land use, impervious surface data, and elevation models. 3D city models and hydraulic simulations allow drainage planning under different rainfall scenarios. Environmental analysts assess how drainage systems affect erosion and wetland health.
