Abstract The current study tried to investigate the hydrodynamic characteristics and pollution mixing dispersion from sub-branch through river confluence using numerical model of Flow3D. A was used with length, width, height (7 × 1 1) m. Also, nested mesh in junction refine modeling result depiction. It observed that if there is a water level difference on both sides junction, will occur much f...

—Studies of the whirling disease epizootic in the upper Colorado River drainage have suggested that Windy Gap Reservoir is a source of the fish-infective actinospore of Myxobolus cerebralis. We divided the reservoir into four quadrants (12 zones) and conducted a core-sampling study to determine the spatial dynamics of actinospore production within the reservoir from late June to early November ...

Triglavska Bistrica is a typical Alpine river in the north-western part of Slovenia. Its recharge area includes some highest peaks Julian Alps. The hydrogeological conditions and flow depend largely on groundwater exchange between karstified aquifer carbonate rocks intergranular glaciofluvial deposits. average volume up to several m3/s. In this study, water samples from different locations alon...

The notion of confluence is prevalent in graph transformation systems (GTS) as well as constraint handling rules (CHR). This work presents a generalized embedding of GTS in CHR that allows to consider strong derivations in confluence analyses. Confluence of a terminating CHR program is decidable, but confluence of a terminating GTS is undecidable. We show that observable confluence in CHR is a ...

Abstract The influence of Karun river inflow on salinity intrusion from the Arabian Gulf towards upper reaches Shatt Al-Arab estuary was evaluated by using Mike11, a one-dimensional numerical modeling technique. simulations results indicated that, during moderate and low flow conditions river, freshwater at 10 40 m 3 /s, respectively, could be capable keeping extent to not exceeded confluence l...

This study presents methodologically consistent length measurements of rivers with a total 40 kilometres or more in the Republic Croatia. These were performed by vectorising river channels from topographic map at scale 1:25,000. Contemporary orthophoto maps used as additional cartographic sources for verification. The approaches to determine starting and ending points rivers, i.e. mouths conflu...

Low-head dam impoundments modify local habitat and alter fish assemblages; however, to our knowledge, the pattern of how fish assemblages in the impoundments relate to local habitat, tributary position, and dam characteristics is still unclear. We used data collected in 62 impoundments created by low-head dams in headwater streams of the Qingyi River, China, to examine relationships between fis...

Ground confluence of term rewriting systems guarantees that all ground terms are confluent. Recently, interests in proving confluence of term rewriting systems automatically has grown, and confluence provers have been developed. But they mainly focus on confluence and not ground confluence. In fact, little interest has been paid to developing tools for proving ground confluence automatically. W...
