This fact sheet describes the hydrological modeling of the La Vieja river basin in Colombia using the Water Evaluation and Planning (WEAP) tool. The project, funded by USAID and running from July 2012 to June 2015, aimed to strengthen societal adaptation to climate change in the management of water resources in the Otún and La Vieja river basins.

• The hydrological model of the La Vieja river basin was developed using the WEAP (Water Evaluation and Planning) tool to simulate hydrology and water resource management across various scenarios. The model was constructed at a sub-basin scale, further divided by elevation bands every 500 meters, and utilized a soil moisture rain-runoff method, which is a one-dimensional quasi-physical model.
• The model incorporated 37 tributary watercourses (both direct and indirect) of the main channel. It accounted for 16 water demands for human consumption in major population centers and 4 demands for hydroelectric power generation on the Quindío river, as well as agricultural and coffee-growing demands in catchment areas.
• The La Vieja river basin covers approximately 2,880 km2 and is distributed across three Colombian departments: Quindío (68%), Valle del Cauca (22%), and Risaralda (10%). It is formed by the confluence of the Quindío and Barragán rivers and serves as a major tributary to the Cauca river, with a general water yield of 34.34 l/s/km2 and an annual water supply of 2,975.74 Mm3.
• To determine climate change adaptation strategies and uncertainties, the project employed the XLRM analytical methodology developed by the RAND Corporation. This resulted in the creation of 1,728 scenarios to be executed via computer programming, with results visualized using Tableau to assist decision-makers.
• Model calibration focused on adjusting peak and base flows, identifying the runoff resistance factor (RRF) and hydraulic conductivity in the root zone (Ks) as the most sensitive parameters. In this study, RRF ranged from 3.00 to 6.50, and Ks ranged from 90mm to 180mm.
• A discrepancy was noted at the 'bocatoma EPA' measurement station in the Quindío river sub-basin, where simulated and measured curves did not correlate well. This led to the hypothesis that the river may be losing water to an aquifer system known as the Glacis del Quindío, though this interaction has not yet been studied by regional entities.
