Gray stormwater infrastructure has a specific hydraulic capacity, which tends to get undersized when receiving the incremental input flow rate coming from new developed areas or from changes in the land use. Implementing sustainable urban drainage systems - SUDS in consolidated urban watersheds is a feasible alternative that allows managing stormwater runoff combined with the traditional infrastructure. However, its use on a massive scale in cities is a challenge for urban planning. This article shows the results from a research oriented to identifying potential areas for applying SUDS as a support for urban planning in order to define strategies for potential application of rain gardens, permeable paving, storage tanks and green roofs by using models from GIS. A case study was conducted to 10 watersheds in Barranquilla (Colombia), which has severe stormwater issues related to runoff volume and peak flow, and where SUDS may be a feasible alternative for runoff management. Physical conditions of the watershed, such as the type of soil, the water table and slope, socio-economic characteristics, land use and other environmental variables were analyzed in a decision making framework model implemented in GIS. The results allowed defining criteria for prioritizing by type of SUDS and location area in order to help ensuring their general effectiveness on the urban watersheds.
