Impacts of Climate Change on Colombia's Water Resources

PI: Lina Acevedo
Institution: Universidad Nacional de Colombia, Medellín, Colombia
General Objective:

To contribute to our understanding and improve forecasts of the hydro-climatic effects of future climate change on Colombia~s water resources, through diagnostic of historical data, and using diverse model outputs of future climate change scenarios for the region of tropical South America. We will focus on the study of the impacts of climate change on average long term water balances and in the dynamics of hydrological extremes (floods and droughts). The results will contribute to assess the vulnerability of water resources of Colombia at national and regional levels with important apllications for water supply and hydrologic design.

Specific objectives:

a.. To quantify the existence of signals of climate change in Colombia, using long time series of hydro-climatic records.

b.. To evaluate the impact of diverse models and scenarios of climate change on diverse hydro-climatic variables including precipitation, soil moisture, evapotrnspiration, runoff and streamflows), in a wide range of space-time scales over tropical South America.

c.. To quantify the effect of diverse climate change scenarios and modelos on the behavior of hydrometeorological extremes (intense storms, floods and droughts) in Colombia, and their implications in hydrological design.

d.. To downscale the results of diverse climate change scenarios and model outputs according to different statistical and physical techniques, with the purpose of studying the probability distribution functions of the dynamics of different hydro-climatic fields at smaller spatial scales.
