Spatio-temporal study of water quality in a subtropical reservoir and related water bodies in Southern Brazil [PDF]

, 2018
The importance of hydroelectricity to the world energy grid motivates the implementation of dams and formation of reservoirs. This implies changes in the ecosystem, and therefore those waters must be constantly monitored.

Estimation of The Relationship Between The Travel Time of Flood Peaks and Peak Discharge on The Poprad River by Multilinear Flood Routing [PDF]

, 2015
The empirical relationship between travel-time of flood peaks and peak discharge was studied on a reach of the Poprad River in Slovakia. The data were fitted by regression and compared with the expected shapes as described in the literature.

A Group Search Algorithm for Optimal Scheduling of Cascade Hydropower Stations

Renmin Zhujiang
The coronavirus herd immunity optimizer (CHIO) algorithm was introduced to address the optimal scheduling problem of cascade hydropower plants, and an improved algorithm called LCHIO was proposed. The CHIO algorithm was enhanced by adopting two strategies: the Latin hypercube strategy for generating initial population solutions and dynamic social ...
