“…Sedimentation rate estimates are relevant to reservoir management practices intended to reduce the sedimentation rates (Morris and Fan 1997, Palmieri et al 2001, López-Moreno et al, 2004. In comparison with the effect of average discharges, the less frequent floods, and especially those 10 times the average annual discharge (Q10), would be responsible for the highest rates of infilling in the Yesa reservoir during the hydrological period from 1959-2000.…”

[1] The depletion of water storage worldwide as a consequence of reservoir sedimentation is a growing problem. Effective sediment management is needed to enhance dam productivity and to extend storage life, thereby avoiding various economic and environmental losses. This paper analyzes reservoir level sediment management from a benefit-cost perspective and suggests desirable management strategies. Dynamic programming simulation has been used to analyze the long-term consequences of dam management decisions regarding reservoir sedimentation. The results indicate that doing nothing is likely to lead to inefficiencies and reduce the social welfare in the long run. Alternatively, introducing reservoir level sediment management can mitigate the economic loss due to reservoir sedimentation. Technical innovations that improve sediment removal capabilities and their cost would be vital for conserving the reservoir water storage.

“…It is reported that annually in the world an average 0.5-1% of the volume capacities of small and large reservoirs is lost because of sedimentation (Mahmood, 1987). Palmieri et al (2001) report that the loss in volume capacity requires an annual replacement cost of US$ 13 billion dollars.…”

Geostatistical approach for the assessment of the water reservoir capacity in arid regions: a case study of the Akdarya reservoir, Uzbekistan

The paper presents results of the application of a geostatistical approach to assess the water resources availability of the Akdarya reservoir in Uzbekistan. This geostatistical approach includes a (semi-) variogram analysis and interpolation (kriging and simulations -turning bands-). Techniques predicting values at unsampled locations for generating digital bathymetric surface models of reservoir bottom conditions for calculating the volume and surface area at a given water elevation are also considered. The simulation enables to have a range of reservoir volumes and surface areas with the same probability in comparison to the kriging and traditional methods.The geostatistical approach creates digital surfaces that represent relatively accurate reservoir bottom conditions and support automated reservoir volumes and surface areas calculations. This in turn significantly reduces time, work load and financial burdens for sedimentation survey projects.
