River cross-section morphology and water sediment conditions are deeply connected. In recent years, the lower Wei has experienced regular flooding drastic changes in river channel shape, causing significant harm to economy development of reaches. This research investigated morphological evolution features based on annual extensive data from hydrological stations Xianyang, Lintong, Huaxian Weihe...

Lake Muzzano (455950N 85541E, 337m a.s.l.) is a hyper-eutrophied lake located in the Tessin region of Switzerland. Almost every year, algal blooms (Microcystis) cover the lake with a thickness of 1–2 cm. These blooms associated with periods of anoxia in summer have led to fish kills in 1967 and 1994. In the hope of avoiding these blooms, a bypass bringing water away from the lake has been estab...

At the multigate sluice structure on a fluvial river, undesired sediment deposition affects normal operation of reservoir in question. Physical and numerical models are hybridized to help explore flow sedimentation patterns. Field laboratory investigations show that is attributable formation large recirculation zones at low medium discharges. As potential countermeasure, an array guide vanes re...

Nutrient and hydrologic conditions strongly influence harmful planktonic and benthic cyanobacterial bloom (CHAB) dynamics in aquatic ecosystems ranging from streams and lakes to coastal ecosystems. Urbanization, agricultural and industrial development have led to increased nitrogen (N) and phosphorus (P) discharge, which affect CHAB potentials of receiving waters. The amounts, proportions and c...
