Numerical morphological modelling of braided rivers is increasingly used to explore controls on river pattern and for applied environmental management. This article reviews and presents a taxonomy of braided river morphodynamic models and discusses the challenges facing model development and use, illustrating these challenges with a case example. The taxonomy is contextualised by an initial dis...

Braided bialgebras were defined by mimicking the definition of bialgebras in a braided category; see [Ta]. In this paper we are interested in those braided bialgebras that are connected as a coalgebra, and such that, up to multiplication by a certain scalar, their braiding restricted to the primitive part is a Hecke operator. To every braided bialgebra as above we associate a braided Lie algebr...

Under a specific tectonic background, the change in paleoclimate can show different facies associations and depositional architecture. The Jurassic China continent was an important region for transforming Paleotethys domain to circum-Pacific domain, its information entirely preserved continental sedimentary successions. Middle Zhiluo Formation, Ordos Basin, at just critical period of paleostruc...

The Triassic Yanchang Formation in the Ordos Basin is one of main exploration targets. Based on detailed outcrop at southern margin Basin, combined with previous results, a systematic analysis lithology, rock assemblage, sedimentary facies characteristics and temporal evolution carried out. results show that Changchang 9 oil-bearing group can be divided into lithofacies types, three types facie...

Wetlands and water bodies in the Parana Delta River and Ibera System of northeast Argentina were studied for scaled chrysophytes. The Delta region of the Parana River is composed of a series of braided channels, streams and lagoons that extend over 17,500km2. Although the Delta is situated in the temperate zone, it experiences a more subtropical climate. The water ways of the Ibera System consi...

Anastomosing rivers constitute an important category of multi-channel rivers on alluvial plains. Most often they seem to Ž . form under relatively low-energetic conditions near a local base level. It appears to be impossible to define anastomosing rivers unambiguously on the basis of channel planform only. Therefore, the following definition, which couples floodplain geomorphology and channel p...

Metric resolution digital terrain models (DTMs) of rivers now make it possible for multi-dimensional fluid mechanics models to be applied to characterize flow at fine scales that are relevant to studies of river hydraulic geometry (HG) and ecological habitat, or microscales. These developments are important for managing rivers because of the potential to better understand system dynamics, anthr...
