‘Effective discharge’ is defined as a discharge that carries maximum amount of sediments over a prolonged period of time. Magnitude–Frequency Analysis (MFA) provides a mathematical framework to determine effective discharge. MFA considers (1) the discharge at a location that follows a lognormal probability distribution and (2) sediment load which e...

... It was distinguished from the circumpolar N. sahlbergi Morton, 1896 by the different cercus and paraproct, while considered as its subspecies on the basis of similar epiproct, coloration and size (Zwick 1973). Later, several closely related Far Eastern Nemoura Latreille, 1796 species were described, and fine details of the epiproct proved to be essential in species distinction (Zwick 2010, Teslenko & Boumans 2018). ...

By finding the epiproct slide preparation of the holotype of Nemoura sahlbergi problematica Zwick, 1973, which was considered to be lost, the identity of the taxon is resolved. It is raised to species rank, Nemoura problematica Zwick, 1973 stat. nov., and Nemoura jilinensis Zhu & Yang, 2003 is considered as its junior synonym. The species is widespread in the Korean Peninsula, known also from NE China (Jilin Province) and the Russian Far East (Khabarovsk and Primorsky Krai). New Korean records are listed, its distribution is detailed and depicted on map. Nemoura sahlbergi Morton, 1896 is known from the Russian Far East but not from China and Korea.
A new species of forest stonefly, Nemoura jixiangwangi Yang & Li, sp. nov., is described and compared with related taxa, based on specimens from the Qilian Mountain National Park, Qinghai Province, northwestern China. Nemoura geei Wu, 1929, Nemoura papilla Okamoto, 1922 and Nemoura securigera Klapálek, 1907 are recorded from the province and the mountain range for the first time.
