To improve our understanding of how fluvial architectures record responses to changes in the ratio between accommodation rate and sediment-supply rate (A/S), two case studies are analyzed, including a densely drilled subsurface fluvial reservoir imaged with a seismic cube, and an outcropping fluvial succession. The subsurface dataset provides a larger, three-dimensional perspective, whereas the outcrop dataset enables observation at higher resolution. On the basis of both datasets, channel-body density, channel-body stacking patterns and their formative river types are interpreted at different scales, and how these may reflect responses to A/S change (the rate of accommodation creation relative to the rate of sediment supply) are discussed. The results indicate that (i) channel-body stacking patterns undergo four evolutionary stages along with the A/S increase, i.e., multi-story, mixed multi- and two-story, two-story, and isolated patterns;(ii) channel-body density decreases along with the channel-body stacking patterns varying from multi-story to isolated;(iii) formative rivers types are interpreted as evolving from braided planforms to braided-meandering planforms and then to meandering ones, with the increase of A/S.展开更多

The bank is in NWW direction, approximately parallel to the coastline. The bank consists of sandy silt or clayed silt. Sand waves and megaripples are observed on the north side, which result from strong tidal currents around the headland and storm waves in winter. These bed forms indicate that the bank is influenced by the modern hydrodynamics. The bank is separated from the coast and Holocene subaqueous clinoform around the Shandong Peninsula in its east part. High-resolution seismic profiles reveal that the bank was formed during two periods： the earlier seismic unit Ua, and later seismic units Ub and Uc which overlays Ua with erosional surfaces on its south side and north side, respectively. As comparing with the clinoform, the bank has a different internal architecture. In the west of the bank, however, topography and surface sediment characteristics suggest that the bank links to the clinoform. The authors propose that seismic Ua is a residual part of early clinoform deposit. After the sediments in the north and south of Ua were eroded by strong currents, the Ub and Uc started to deposit probably by a complex hydrodynamic process. These results provide new insights into the evolution of the bank and its relation with the Holocene subqueous clinoform.展开更多

Visual art space is based on spatial vision, artistic forms of point, line, surface and body are major visual elements of spatial form. Visual elements can be demonstrated in various forms, and even more diversified in the context of spatial design, interact with each other according to the form principle of beauty, and construct artistic forms of the space. Manifestation of the nature of public art also relies on visual elements, and the public aesthetic experience and feelings about architectural public art are expressed by visual elements.展开更多

In that sense, the primary objective of this study is to examine the Core Concepts and Forms of traditional architecture, as well as their cultural connotations, in three regions of Saudi Arabia: the central, eastern, and western regions. Non-participant observation, ethnographic, and descriptive approaches were used in the study, which was based on a multi-dimensional comparative observational model. It was determined that the traditional Saudi built environment relied on forty Core Concepts and Forms that were divided into four categories: constant, semi-constant, semi-flexible, and flexible core forms to regulate the production process and maintain its continuity over centuries.展开更多
