A global water supply reservoir yield model with uncertainty analysis

Uncertainty analysis for water supply reservoir yields

Global Storage-Reliability-Yield Relationships for Water Supply Reservoirs

Storage-Reliability-Yield (SRY) relationships are used to determine the reservoir storage capacity for delivery of a specified yield with a given reliability, or to compute the yield and/or reliability of an existing reservoir system. Several studies have developed generalized SRY relations using synthetic inflows arising from a variety of theoretical streamflow models. Fewer studies have used ...

An Integrated Model for a Two-supplier Supply Chain with Uncertainty in the Supply

The objective of this paper is to study an integrated two-supplier supply chain whose suppliers are unreliable. An unreliable supplier is alternative between available (ON) and unavailable (OFF) states which are considered to be independent exponential variables. The suppliers apply a continuous review policy and the retailer uses an adapted continuous review base on an(R,Q) policy. Transportat...

Reservoir Model Optimization under Uncertainty

Computerized reservoir simulation models are widely used in the industry to forecast the behavior of hydrocarbon reservoirs and connected surface facilities over long production periods. These simulation models are increasingly complex and costly to build and often use millions of individual cells in their discretization of the reservoir volume. Simulation processing time and memory requirement...

Revisiting reservoir storage–yield relationships using a global streamflow database

Annual and monthly streamflows for 729 rivers from a global data set are used to assess the adequacy of five techniques to estimate the relationship between reservoir capacity, target draft (or yield) and reliability of supply. The techniques examined are extended deficit analysis (EDA), behaviour analysis, sequent peak algorithm (SPA), Vogel and Stedinger empirical (lognormal) method and Phien...
