Jun 26, 2024 · Hydrological processes and the sustainable use of water resources in a river basin are altered by climate change and changes in human variables. This study examined the significant effects of vegetation and hydrological, climatic, and human activity changes on the basin’s biological environment and usage of water resources. The Min River Basin (MRB) in the upper Yangtze River served as the study location. Mann–Kendall and Pettitt mutation test techniques were used to examine the features ...
4 days ago · River Thames. The Thames is some 205 miles (330 km) long, running 140 miles (226 km) from the source to the tidal waters limit—i.e., from Thames Head to Teddington Lock —and, as an estuary, a further 65 miles (104 km) from there to The Nore sandbank, which marks the transition from estuary to open sea. Its basin, which receives an annual ...
Jul 1, 2024 · River - Deltas, Time, Formation: One of the most important perceptions needed to understand deltas is how their depositional framework changes with time. Because delta characteristics are controlled by factors that are subject to change, it follows that deltaic growth patterns are dynamic and variable. The most significant effect is that the site of deposition shifts dramatically with time. This occurs because the channel gradient and transporting power of a delta river decreases as the ...
6 days ago · From 1048 to 1194 changes in the course of the river occurred farther inland, where the river enters the North China Plain. In 1194 the river occupied a course running to the southern edge of the delta. In that year, after protecting dikes had been ruptured, a second arm of the Yellow River began flowing south of the Shandong Peninsula.
Jun 21, 2024 · This book provides an analysis of the ecological conditions and ecosystem goods and services of the Zambezi River Basin (ZRB), the fourth largest river in Africa. Various environmental and anthropogenic factors; inclusive of climate, environmental flows, hydrology, morphology, pollution and land use changes among others and their interactions are considered as drivers of the river ecosystems. The impacts of these drivers on aquatic biota, river ecological integrity, and the livelihoods of ...
Jul 1, 2024 · River - Valley Formation, Erosion, Deposition: The ultimate form assumed by any valley reflects events that occurred during its developmental history and the characteristics of the underlying geology. During initial valley development in areas well above regional baselevel, valley relief tends to increase as rivers expend most of their energy in vertical entrenchment. Valleys are generally narrow and deep, especially in areas where they are cut into unfractured rocks with lithologic ...
