The data basis for functional-morphological analyses has considerably broadened (census statistics, etc.). The positions of the mid-Békés towns in the settlement network have changed. Functions modified at a more rapid rate than morphology. (DLO).
Gravel transport and morphologicalchange in braided Sunwapta River, Alberta, Canada
The relation between morphologicalchange and patterns of variation in bedload transport rate in braided streams was observed by repeated, daily topographic surveys over a 25 day study period in a 60 m reach of the proglacial Sunwapta River, Alberta
, Canada. There are two major periods of morphologicalchange, each leasting several days and each involving the complete destruction and reconstruction of bar complexes.
Eger kialakulasa és fejlodése, funkcionalis és morfologiai valtozasai. (Development and evolution of Eger, its functional and morphologicalchanges)
The development of the North Hungarian town during Medieval times, in the period of capitalism and after the Liberation is studied with respect to morphological zones, distribution of industry and population and town planning.
Morphology of the Itapeva to Tramandai transgressive dunefield barrier system and mid- to late Holocene sea level change
The surface morphology of the transgressive dunefield barrier extending from Itapeva to Tramandai along the northern littoral of Rio Grande do Sul, is examined and an attempt is presented to link morphologicalchanges across the barrier to Holocene
spaced washouts during the falling period, and that this change in sea level from rising to falling therefore produced the large-scale differences in barrier morphology.
sea level changes. The AA. argue that the effect on barrier development was to suppress the development of a drainage system during the rising and maximum stages, and encourage the development of an organized drainage system in the form of regularly
Evaluating proxies for estimating subaerial beach volume change across increasing time scales and various morphologies
This study assesses the impacts of morphologic variations, associated with beach cusps and nourishment material, on volume change estimates from profiles and shoreline change at 0.5 to 3.5 year time periods. Volume changes at the edges
of nourishment areas are not captured well by profiles. When the nourishment material is graded to a ramped morphology, which minimizes across-beach morphologic variability, the shoreline-change proxy does accurately estimate volume changes. Both proxies estimate
volume changes inaccurately at beaches where volume changes oscillate between erosion and accretion on both short and long time scales because the magnitude of small-scale changes in volume from the formation and erosion of morphologic features
, such as cusps and berms, will always be similar to the longer-term net volume change. This study suggests that decadal records of shoreline change, which are commonly developed using aerial photography, can be used to help identify the best proxy for estimating
volume change; however, recent anthropogenic modifications that impact patterns of beach sedimentation, including nourishment, terminal groins, and inlet-channel dredging, makes decadal records less useful.
Changes in stream channel characteristics at tributary junctions
The classifications presented in this paper confirm that changes in stream channel morphology and sedimentology at confluences are complex. These changes do not conform strongly to expected relationships based on hydrologic considerations alone
. This study has shown that expected relationships exist only at relatively symmetrical junctions (Q2/Q1 > 0.7), where the simultaneous hydrological responses of the tributaries predominantly control channel morphology and sediment properties.
Morphological development of dunes in a subarctic environment, central Kobuk Valley, northwestern Alaska
The morphology of the dune fields is described by airphoto interpretation supplemented by field observations. Dune forms indicate that both present-day and former wind directions are parallel to the valley axis. Therefore it is proposed that wind
directions have not changed significantly since the last glacial time.
Seasonal variation of crescentic dune morphology and morphometry, Strzelecki-Simpson Desert, Australia
This short communication discusses the changes in crescentic dune morphology that accompany seasonal variation in wind directions for the Strzelecki-Simpson Desert, at Gurra Gurra waterhole.
In the coastal karstic area of the southeastern Murge (Apulia, Italy) changes in sea level, due to vertical tectonic movement and/or global climatic phenomena, generated morphological effects both at the surface (marine terraces) and underground
(variations of karstic base level), so by integrating and comparing observations of surface and subsurface morphology, a more reliable picture of the structural and palaeogeographical evolution was obtained. The calculation of topographic gradients
and spectral analysis of the topographic surface was applied to identify the morphological remnants left by coastal terraces.

Evolution of the morphology of the river Dragonja (SW Slovenia) due to land-use changes
In this paper, the impact of human interference and especially the effects of reforestation on the river morphology of the Dragonja river is studied. Furthermore, the spatial variability of river response to land-use change in the catchment
Thresholds for morphologicalchanges on an exposed sandy beach as a function of wave height
and vertical profile variations and to define wave thresholds for important morphologicalchanges. Results show that the active zone of the profile lies between 5 m above and 10.4 m below mean sea level. Based on the pattern of vertical variability, the AA
. divided the profile into 4 cross-shore sectors and calculated thresholds for significant wave height generating important morphologicalchanges in each sector.
This article investigates the morphological evolution of Sudanese and involves consideration of town planning, building form, and the pattern of land and building utilization.It identifies three broad morphologies: indigenous, African-Islamic
, and European style (colonial). The ongoing, rapid urbanization of African cities in general and Sudanese cities in particular points to a need to understand the structure of this urbanization. The morphology of cities includes not only physical structure
, but the cultural heritage, economic, and historical values on which it is based. Therefore, preservation, redevelopment, and urban policy underlying future urban expansion must be based on the nature of cities’ morphologies and development.
