—Fisheries for American eel Anguilla rostrata occur mostly in estuaries, yet eel abundance in large estuaries is poorly understood and the methods for estimating eel density underdeveloped. During 1997–1999, mark–recapture experiments were conducted for six consecutive days at six sites spanning the 250-km tidal portion of the Hudson River estuary, New York. Each experiment comprised 36 baited ...
Multifractal theory provides an effective method for the scientific quantification of river network features. This has been applied to estimate structure in previous research, but there are few temporal and spatial analysis studied large basins based on multifractals. In this study, Yellow River Basin its nine provinces were selected as study area, generalized fractal dimension multifractal spe...
Clarifying the relationship between salt-affected soils and their adjacent river systems is critical to address challenges posed by soil salinization on agricultural production. Among various biophysical land management factors linked salinization, few studies have investigated importance of distance along river. Based Hetao Irrigation District Yellow River Basin, we collected 5314 samples anal...
(CSC) " , " Het Lamminga Fonds " , and the Sino-Dutch collaboration project " Effects of human activities on the eco-morphological evolution of rivers and estuaries " (08-PSA-E-01) funded by the Royal Dutch Academy of Sciences (KNAW) and the Chinese Ministry of Science and Technology (MOST) within the framework of the Programme of Scientific Alliances between China and the Netherlands. Summary ...
The natural runoff mechanism of the Dawen River, main tributary lower Yellow has been stressed in recent years as a result human activity, and hydrological situation changed dramatically. In this paper, various statistical methods such Mann–Kendall nonparametric test, cumulative anomaly, ordered clustering, sliding T rainfall–runoff double-cumulative curve were used to study evolution character...
