Long term predictability of river stages under ENSO influence
TL;DR: In this paper, the authors explored the bases for alternative approaches to river flow and hydrologic time series forecasting and found that the precipitation that forces river flow contains significant modes of variability beyond simple noise randomness and these structured statistical properties may be used advantageously in forecasting river flow.
Using forecasts to improve reservoir operations

TL;DR: In this paper, a review of methods to incorporate streamflow forecasts into reservoir policies and operating decisions is presented, including the use of streamflow forecast in deterministic optimization models, use of multiple stage decision trees, stochastic analytical optimization models with linearized reservoir dynamics, and sophisticated stochastically models that can describe the joint distribution of streamflows and forecasts in the optimization of reservoir operations.
