The actual efficiency of water storage is very low

Can efficiency improvement increase the demand for storage capacity?

We show that they are not always substitutes. Efficiency improvement can increase the demand for storage capacity in two scenarios: (1) if it increases water demand; (2) if, as a result of re-optimization of water inventory control, it increases the probability that the storage capacity will be exhausted.

Does increasing water storage capacity increase the value of stored water?

Increasing water storage capacity also has the potential to increase the value obtained from stored water as supplies become scarcer. However, with biased management objectives, the impact of additional storage is ambiguous.

How does water management affect storage capacity?

In reality, a large portion of water management involves the allocation of water at a daily or even subdaily time step. Therefore, to capture the value of changes in storage capacity, it is important to account for changes in the ability to control the delivery of water at a finer time scale.

How does minimum reservoir storage affect water demand?

Increasing minimum reservoir storage to manage the cold-water pool has a large effect on other water demands because constraining minimum reservoir storage effectively shrinks storage capacity for these demands and reduces the total volume of water that can be carried over from wet years for use in later years (Fig. 5G, H).

Why is water storage important?

Beyond peak reservoir storage? A global estimate of declining water storage capacity in large reservoirs Water storage is an important way to cope with temporal variation in water supply and demand. The storage capacity and the lifetime of water storage reservoirs can be significantly reduced by the inflow of sediments.

Why is water use efficiency important?

Water use efficiency (WUE) is an important indicator of plant drought resistance, and high WUE is an important way to reconcile the contradiction between vegetation growth and soil water consumption (SWC). Different vegetation types significantly influence hydrological cycle process and WUE.
