This paper demonstrates how suspended sediment trapped by dam construction may impact the quantity of dissolved organic matter (DOM) exported discharge entering Three Gorges Reservoir (TGR). Suspended and water samples were collected along upper Yangtze River its major tributaries, their properties determined. The results provided evidence more polluted nature tributaries compared to mainstream...

Land use pattern is one of the most important factors affecting quality habitats, which taken as research objective in this study. Based on land data Ciyao river basin from 1985 to 2020, transfer matrix analysis, superposition and zoning statistics were carried out by ArcGIS. The impact main threat sources (cultivated land, urban rural residential land) water was calculated using investment mod...

The bisphenol A (BPA) concentration was determined in 12 surface water samples of the Vrbas River and its five tributaries. were taken area that belongs to city Banja Luka (Bosnia Herzegovina). BPA isolated using micro liquid?liquid extraction followed by derivatization gas chromatography?mass spectrometry analysis (GC?MS). Silylation used as a method increase volatility allow GC?MS determinati...

Open channel junction is one of the most common hydraulic structures that are used in various practical situations such as sewer, drainage, and flood control systems. Knowing the fluid flow behavior, is one of the most important topics in designing the efficient open channel junctions. The complexity and deviation of flow in the junction’s zone disrupts the proper functioning of the flowmeter d...

Background: In the field of cellular therapy, the impact of confluence degreeonharvesting or differentiation of BMMSCs and the effect of cell-to-cell contact remain controversial. Therefore, the effect of confluence on properties of BMMSCs was studied and efficiency of confluence-associated osteogenic differentiation was identified. Materials andMethods: The impact of 20, 50, 70, 80 and 100% co...

Constraint Handling Rules (CHRs) are a powerful rule based language for specifying constraint solvers. Critical for any rule based language is the notion of confluence, and for terminating CHRs there is a decidable test for confluence. But many CHR programs that in practice are confluent fail this confluence test. The problem is that the states that illustrate non-confluence are not reachable i...

The SiXianJiao (SXJ) is the first-order exchange node of West River and North redistributes water (mass) to downstream river network in Pearl Delta (PRD), South China. lateral SXJ waterway plays a critical role flow diversion between River, forming unique H-shaped compound node. Previous studies mainly focused on Y-shaped bifurcation confluence nodes, there lack research deltaic nodes. This stu...

Because of differences in the underlying surface, short flood confluence times, extreme precipitation, and other dynamic parameters, it is difficult to forecast an inflow a basin reservoir, traditional hydrological models do not achieve accuracy required for control operations. This study Fengshuba Reservoir China evaluated capacity Liuxihe model, which based on physically distributed predict f...

Cherry Valley Creek (CVC) flows from its headwaters in the town of Cherry Valley and runs south to its confluence with the Susquehanna River in the village of Milford. While historical accounts of its water quality are mostly anecdotal in nature, CVC apparently once had water of such a quality to support populations of trout. The DEC had stocked the creek with brown trout (Salmo trutta) until 1...

Paddlefish, Polyodon spathula (Walbaum), provide an important snagging and bowfishing fishery below Gavins Point Dam in South Dakota. During 2009–2020, catch rates of paddlefish decreased to presumed “normal” lower pre-2004 levels, while (harvest) significantly increased during 2000–2020. Because Paddlefish are highly migratory, both local (i.e., monthly gauge height, precipitation, air tempera...
