Mitigating the effects of hydrologic variability in Ethiopia: an assessment of investments in agricultural and transportation infrastructure, energy and hydroclimatic forecasting por Block, Paul J.

“…The model indicates that large-scale development typically produces b-c ratios from 1.6- 2.1 under historical climate regimes for the projects specified. Climate change scenar- ios indicate potential for small b-c increases, but reflect possible significant decreases. stochastic modeling of scenarios representing a doubling of the historical frequency of El niño events indicates b-c ratios as low as 1.0 due to a lack of timely water. …”
