Abstract:
... The pollution of antibiotics commonly existed throughout the entire aquaculture process, but the residues of antibiotics at different aquaculture stages have rarely been studied. This study investigated the occurrence, distribution and risk assessment of antibiotics at different aquaculture stages (the non-aquaculture stage, the early aquaculture stage, the middle aquaculture stage, and the late a ...

Abstract:
... Phosphorus (P) in sediments plays an important role in shallow lake ecosystems and has a major effect on the lake environment. The mobility and bioavailability of P primarily depend on the contents of different P forms, which in turn depend on the sedimentary environment. Here, sediment samples from Baiyangdian (BYD) lake were collected and measured by the Standards, Measurements, and Testing proc ...

Abstract:
... Sustaining environmental flows (e‐flows) is a basic requirement for river, lake and marsh management. Rivers, lakes and marshes have close hydrological and ecological connections in a river basin, and form river–lake‐marsh systems. Any measure that is designed to address problems related to only one of these water bodies in isolation of the others may lead to unexpected, undesired and sub‐optimal ...

Abstract:
... Non-staggered triangular grids have many advantages in performing river or ocean modeling with the finite-volume method. However, horizontal divergence errors may occur, especially in large-scale hydrostatic calculations with centrifugal acceleration. This paper proposes an unstructured finite-volume method with a filtered scheme to mitigate the divergence noise and avoid further influencing the v ...

Since movement of fish is the most crucial thing in the healthy river environment fish passes are necessary to predict in any place where hydraulic structures are designed or any river engineering works are applied in the river channel. Thus in our paper we are giving a proposal ...

Abstract:
... A debris flow flowing into a river may cause river blockage and form a dam. When the dam breaks, large floods can occur in the areas downstream, which can lead to fatalities and property damage. In this study, the parameters of river blockage were classified as three types of factors: morphological factors, dynamic factors, and characteristics factors of debris flows. The confluent angle, the dime ...
