This research evaluates natural flood management strategies in a mountain basin, the Olivares-Minitas creek in Manizales, Colombia, to quantify the effectiveness of their application in reducing floods. Hydraulic and hydrological modeling was performed simultaneously in Iber software. Multiple scenarios were proposed for three natural flood management alternatives: (1) making room for the channel, eliminating contractions and structures limitations, (2) changing the vegetation cover of the upper part of the basin, increasing the ground roughness, and (3) reconnect the stream with their floodplains, allowing the stream to dissipate flow and energy. Applying these strategies, the simulations resulted of the decrease the high discharges and the delay in peak times for the hydrographs. In conclusion, from natural solutions like rehabilitating, recovering the water body, and their ecosystem, is possible to manage and reduce the flooding risk, Attaining benefits through long-term reduction of flooding and enhancement of the river and its ecosystem.

A methodological approach which overcomes the lack of data available for 2D hydrodynamic modeling in deltaic floodplains is proposed. By digitizing the elevation data available in Google Earth™ and integrating them with river cross sections data surveyed on the field, plus additional topographic data available, a topographic point cloud was obtained. This was later interpolated in a Triangulated Irregular Network, and finally, a Digital Terrain Model was generated. A two-dimensional simulation (with IBER v2.3.2) for a flood event together with a solution alternative including a structural measure (levee) to protect a vulnerable community were carried out. Overflow occurred only in the final stretch of the riverbed. Therefore, it did not influence the urban area of the city of Riohacha. The levee would artificially avoid the flooding on the target area for protection but increasing the flood risk due to possible failure that would occur when a swelling river occurs. Based on results, the proposed methodology is useful for determining flood prone areas in deltaic zones and well supports decision making in data-scarce regions. [ABSTRACT FROM AUTHOR]
