Abstract:
A structural landform is defined by its surface morphology, controlled by tectonics, lithology (arrangement and resistance), and folded structures, and demonstrated by the characteristics and relationships between geological and geomorphic elements. It is very important to use geographic information system (GIS) technology to accurately describe and express elements of structural landforms and their relationships. In this study, a GIS approach for expressing structural landforms, based on “forms–elements–relationships”, was developed. The contributions of this paper are as follows: (1) Combined with the surface morphological characteristics, the structural landforms were abstracted into geological and geomorphic elements, and the characteristics and relationships of these elements were analyzed. (2) The elements of structural landforms and their relationships were abstracted into spatial objects and topological relationships. The spatial objects of the structural landform were designed based on the types and characteristics of structural landform elements. The topological relationships were developed based on the definition of the structural landform morphotype. (3) The structural landform markup language (SLML) method of “forms–elements–relationships” was created. (4) Two typical structural landforms, namely, Qixia Mountain and Gaoli Mountain, were used as examples to verify the feasibility and effectiveness of the GIS approach for expressing structural landforms. This paper describes and expresses the “forms–elements–relationships” of structural landforms from the perspective of GIS, which is expected to promote the joint development of structural geomorphology and GIS.

Abstract:
In this study, spatial distribution analysis was conducted on the landforms that appear within the 1st grade area using the ecology and nature map of 2023. As a result, a total of 97 landforms including tidal flat and incised meander were identified as unit landforms, and a total of 1,490 sites were distributed. The spatial distribution by administrative region was highest in Gangwon-do with 273 sites (12.8%), and by unit landform, cliff (173 sites), stream cliff (129 sites), and sea cliff (100 sites) were the most distributed. These landforms are cliffs found in mountainous, riverine, and coastal areas, respectively, and are characterized by their high geomorphological conservation value due to their large scale and geometric shape compared to other terrains. In terms of spatial distribution by landform type, stream landforms (501 sites, 33.6%) accounted for the largest proportion, and there were 24 units landforms. The results obtained can be utilized for future designation of expanded ecosystem protection areas or ecosystem monitoring surveys, along with continued landform conservation.

Abstract:
A landform is an area of a terrain with its own recognisable shape. Its definition is often qualitative and inherently vague. Hence landforms are difficult to formalise in view of their extraction from a DTM. This paper presents a two-level framework for the representation of landforms. The objective is to provide a structure where landforms can be conceptually designed according to a common model which can be implemented. It follows the principle that landforms are not defined by geometrical characteristics but by salient features perceived by people. Hence, these salient features define a skeleton around which the landform is built. The first level of our model defines general concepts forming a landform prototype while the second level provides a model for the translation of these concepts and landform extraction on a DTM. The model is still under construction and preliminary results together with current developments are also presented.

Abstract:
Landforms are the core concept of geomorphology. The definition of landforms, their characterization and classification are the core subject of geomorphology. But all these become complex when it seems to difficult to identify the landforms, especially when the area is plain land and highly modified by human activities. This paper has examined the characters of the landforms of the middle basin of the Ichamati river, the important distributary in the district of North 24 Parganas, India. It has been primarily taken an attempt to classify the landforms with the help of the satellite image, IRS P6 LISS II and LISS III. The DEM is not enough to identify the micro scale landform. To overcome this difficulty a series of field works have been conducted (2002, 2004, 2012 and 2015). The landforms have been classified according to second order derivative (Wood, 1996) method. Then ANOVA test has been applied to justify the classification. The F-statistics have indicated the effort is satisfying. The changing character of different landforms denote the river is going to be deteriorating from downstream to upward.

Abstract:
Landforms determine the locations of particular biological communities based on their components and spatial positions. This study hierarchically classified the topographic spaces serving as habitats for biological communities in the Korean Peninsula and established the habitat types that occur on the classified landform types. We classified landform types by applying cell-based modeling, map algebra, and spatial query techniques to spatial data, including digital elevation model (DEM), Sentinel 2 image, land use, and field survey data to model their ecological characteristics. Landforms were classified into four categories (designated Category 1 through 4) according to their spatial scale based on topographical characteristics such as mountains, plains, alluvial landforms, coastal landforms, islands, and special areas (Baekdudaegan, DMZ), which are found throughout the Korean Peninsula. The landforms of the Korean Peninsula were classified into 47 subcategories in Category 1, 16 in Category 2, 36 in Category 3, and 63 in Category 4. There were 62 main types of habitats that were classified based on their topographic spatial units, and there were 437 types of sub-habitats, for which soil weathering, biodiversity, and geodiversity were combined with the main habitat types. When factor analysis was conducted for the environmental factors used to determine the main and sub-habitats, the first primary components were temperature-related factors, followed by biodiversity, geodiversity, aspect, and slope. When the indicator species were analyzed by habitat type, indicator species diversity was high in Jeju Province, Gangwon Province, and Gaema Plateau. Based on these results, landform elements for species habit conservation were assigned conservation values and classified into (I) absolute conservation areas, (II) transition areas, and (III) areas for coexistence with humans. Topographic spaces are being degraded as biological habitats as a result of climate change and human development; our proposed classifications can be applied to the conservation of landforms and biodiversity.

Abstract:
Schmidt-hammer exposure-age dating (SHD) was applied to a variety of boulder-dominated periglacial landforms in an attempt to establish a local mid-/late-Holocene chronology for the Geirangerfjellet in South Norway. Landform ages were obtained by application of a local calibration curve for Schmidt hammer R-values based on young and old control points comprising fresh road cuts and a bedrock surface in proximity to the study area, respectively. The area was deglaciated ~11.5 ka ago according to independent age information. Investigation of age, formation and stabilization of the periglacial landforms and processes involved allowed assessment of the underlying Holocene climate variability and its relationship to landform evolution. Our SHD ages range from 7.47 ± 0.73 ka for glacially abraded bedrock at the valley bottom to 2.22 ± 0.49 ka for surface boulders of a rock-slope failure. All landforms shared negative skewness and largely have narrow tailed frequency distributions of their R-values. This points to either substantial reworking of the boulders within a landform or continuous debris supply. Our results show that most landforms stabilized during the Holocene Thermal Maximum (~8.0–5.0 ka). The findings do not support the hypothesis that rock-slope failures predominately occur shortly after local deglaciation. Instead, it appears that they cluster during warm periods due to climate-driven factors, for example, decreasing permafrost depth or increasing cleft-water pressure leading to slope instabilities. Periglacial boulder-dominated landforms in the western maritime fjord region seem to react sensitively to Holocene climate variability and may constitute valuable but to date mostly unexplored sources of palaeoclimatic information.

Abstract:
Abstract. This paper presents an automated landform classification in a rockfall-prone area. Digital terrain models (DTMs) and a geomorphological inventory of rockfall deposits were the basis of landform classification analysis. Several data layers produced solely from DTMs were slope, plan curvature, stream power index, and shape complexity index; whereas layers produced from DTMs and rockfall modeling were velocity and energy. Unsupervised fuzzy k means was applied to classify the generic landforms into seven classes: interfluve, convex creep slope, fall face, transportational middle slope, colluvial foot slope, lower slope and channel bed. We draped the generic landforms over DTMs and derived a power-law statistical relationship between the volume of the rockfall deposits and number of events associated with different landforms. Cumulative probability density was adopted to estimate the probability density of rockfall volume in four generic landforms, i.e., fall face, transportational middle slope, colluvial foot slope and lower slope. It shows negative power laws with exponents 0.58, 0.73, 0.68, and 0.64 for fall face, transportational middle slope, colluvial foot slope and lower slope, respectively. Different values of the scaling exponents in each landform reflect that geomorphometry influences the volume statistics of rockfall. The methodology introduced in this paper has possibility to be used for preliminary rockfall risk analyses; it reveals that the potential high risk is located in the transportational middle slope and colluvial foot slope.

Abstract:
Landforms are created, reshaped or eliminated to suit human needs. These alterations affect the mechanisms of change, freedom of movement, locations of sources and sinks for sediment, internal structure, outward appearance and spatial and temporal scales of landform evolution. The processes by which landscapes are transformed by human agency follows a progression of alterations that may be subtle or overt, planned or unplanned, but most of them are predictable. Models of change for human-altered coasts may be formulated by viewing them as open or closed systems. Alternative methodologies for examining evolution of these coasts include: 1) comparing and contrasting a developed area with an undeveloped area that is assumed to have the same process controls; 2) assuming that the kind of shoreline change that occurred in the recent past will continue unabated by local actions; or 3) basing predictions on probabilities of future human action. Evidence suggests that human alterations are an integral component of landscape evolution. Future challenges for scientists include: 1) formulating conceptual and predictive models of landform dynamics that evaluate humans as an endogenic process and include assumption about human actions; and 2) providing scientific criteria for maintaining landforms in developed areas in ways that safeguard or promote an optimal diversity of landforms, species and ecosystems. Controlled disturbance may be required to create landforms compatible with natural landforms in appearance and function if not in genesis.

Abstract:
Even though soil degradation challenges sustainable development, the use of degradation indicators such as nutrient export (NE) and nutrient replacement cost is not well documented at landform level. This study is aimed to investigate the extent of soil degradation, NE rates, and their replacement cost across landforms in the Mai-Negus catchment, northern Ethiopia. Different erosion-status sites (aggrading, stable, and eroded) in the landforms were identified, and soil samples were randomly collected and analysed. Nutrient export, replacement cost, and soil degradation were calculated following standard procedures. This study showed that soil degradation in the eroded sites ranged from 30 to 80% compared to the corresponding stable site soils, but the highest was recorded in the mountainous and central ridge landforms. Average NE of 95, 68, 9.1, 3.2, 2.5, and 0.07 kg ha−1 y−1 for soil calcium, carbon, nitrogen, potassium, magnesium, and phosphorus, respectively, was found from the landforms. Significantly strong relationships between NE and sediment yield in the landforms were observed. Annual nutrient replacement costs varied among the landforms though the highest was in the reservoir (€9204 in May 2010). This study thus suggests that while introducing antierosion measures, priority should be given to erosion sources to the reservoir such as mountainous and central ridge landforms.

Abstract:
O trabalho consiste na realização de um zoneamento geoambiental para a região de Piracicaba-SP, com base na análise de variáveis ambientais, principalmente de atributos do meio físico, tais como: geologia, solos, hidrologia, etc. A área estudada localiza-se na bacia hidrográfica do Rio Piracicaba, uma das mais importantes do estado de São Paulo e que vem apresentando intenso desenvolvimento econômico e consequentemente problemas de degradação ambiental. Este estudo foi realizado seguindo-se os pressupostos da cartografia geoambiental, mas utilizando-se também os procedimentos da cartografia geotécnica tradicional. Incorporou-se ainda ao estudo a utilização de um Sistema de Informações Geográficas (SIG) e do processamento digital de imagens de satélite, que permitiram maior agilidade e confiabilidade no levantamento, análise e tratamento das informações. Para a obtenção da carta de zoneamento geoambiental partiu-se da compartimentação do terreno em \"Landforms\", sendo que estas unidades homogêneas foram então caracterizadas e avaliadas quanto as suas principais aptidões e restrições. A carta obtida apresenta-se dividida em 16 unidades, descritas quanto a aptidões, restrições e conflitos de uso, principalmente em relação a aptidão agrícola, erosão, vulnerabilidade do aqüífero e disposição de rejeitos.
This work presents the geoenvironmental mapping of the Piracicaba (SP) region, based on the analysis of environmental attributes, such as: geology, soils and surface and ground waters. This region is located in the Piracicaba river basin, one of the more importance basins in the São Paulo state. It presents serious environmental degradation problems due to intense economic activities. This study has been based on the proposal of the geoenvironmental mapping, but using to the procedures of the traditional Engineering Geological Mapping. A Geographical Information System (IDRISI) and digital image processing were used to permit quickness and confidence on the collect, analysis and handling of the geological-geotechnical informations. The geoenvironmental zoning chart has been based on the terrain landforms division and the characterization of these homogeneous units that were evaluated with respect to the mainly aptitudes and constraints. The region was divided into 16 geoenvironmental units with their advantages and limitations analised in terms of agriculture aptitude, erosion susceptibility, aquifer vulnerability and waste disposal.

Abstract:
This thesis examines coastal form and sediments of the Marlborough Sounds, New Zealand. An important aspect of coastal behaviour in this landscape stems from linkages between catchment and coast. Focus is therefore placed on the manner in which sediment delivered from catchment sources is redistributed within the shore and offshore domains. Coastal response is shown to depend on two factors: the form of the receiving sites and the mobility of sediments within them. Investigation of coastal landforms at a range of scales identifies the framework within which sedimentation takes place. Consideration of landscape sediment redistribution at Quaternary, Holocene and human timescales establishes the locations in the coastal landscape in which change has taken place. A key factor in coastal response relates to the wide size range of sediments delivered. The fractionation of sediment within the coastal domains is used as an index by which to identify the controls on coastal sedimentation. A new conceptual model of coastal behaviour, the Ordered Response Model, is developed as a framework within which to investigate coastal response. The model is operationalised in three ways. This is done first with regard to coastal sediments and their grain-size interpretation, secondly in the context of shoreline form and sediment redistribution, and thirdly in relation to form and sediment trapping within coastal embayments. The patterns of sediment redistribution are seen to reflect trapping behaviour in the coastal landscape at a range of scales. Sediments are investigated from the viewpoint of the factors which determine their retention or accumulation in or rejection from a coastal site. Shore sites are distinguished on the basis of the extent to which they trap materials delivered to them from catchment sources. Governing factors are shoreline gradient and size grade of materials. A primary fractionation of sediments takes place at the shore and the finer fractions are by-passed to the nearshore. Sediment fractions that are relatively immobile under prevailing environmental conditions develop paved lag surfaces at a range of scales. Sediments that accumulate at the shore are distinctive in their mixed sand and xv gravel composition with a dominant mode in the granule and very coarse sand grades (-291 to 091). Sediment deposited on the intertidal surfaces is found to be redistributed by a distinctive mechanism. Migratory intertidal bedforms defined here as "clastic waves" are a means by which the low energy shores disperse sediment which is delivered to them. These waves are a distinctive form of the shoreline of the Marlborough Sounds, and have attributes different from other shoreline forms identified in the literature. Clastic waves are shore-parallel, crescentic or lunate forms with longshore crest dimensions of 0.5 to 30m, length dimension perpendicular to the crest of up to 20m, and crest heights of 0.05m to 0.5m. Rates of intermittent migration vary from 1m/day to 10m/year. Key factors in their development are identified as low wave energy, tidal range, intermediate to low intertidal gradients (<1:20) and a mixed sand and fine gravel grain-size. Bathymetric form is found to reflect the varying influence of sub-bottom morphology, sediment accumulation and hydraulic reworking. Analysis of sediment thickness identifies a mean thickness over sub-bottom of 7.33m in Pelorus Sound. Spatial variations in sediment thickness identifY marginal embayments as significant sediment traps. Mean sedimentation rates calculated over a 6,000 year timespan give Pelorus Sound a spatially averaged rate of 1.22mm/yr. Sub-bottom form is shown to have a stronger role in determining bathymetric form than previously reported. Due to the constraining effect of shallow sub-bottom form on sedimentary processes sediment thicknesses in the inner Pelorus Sound are not greater than those found in channels or embayments in the middle reaches of the Sound. A mean thickness of 5.75m from sub-bottom seismic profiles in the inner Pelorus equates to a sedimentation rate of 0.96mm/year over 6,000years, at about which time the river valleys of the Marlborough Sounds were drowned by postglacial rising sea-levels. Analysis of sub-bottom form reveals evidence of previously unreported drowned terrace remnants, which are correlated to subaerial terrace remnants. On the basis of both long profile patterns along these remnant surfaces and an analysis of bathymetric form of marginal bays and channels, an interpretation is developed of the origin of form in Pelorus Channel and Tory ChanneL Sediment trapping behaviour is identified as the most distinctive attribute of this coastal landscape, and shown to operate at a range of nested scales. As a XVI consequence of trapping behaviour, the operation of any part of this coastal landscape must be considered in relation to its operation as a whole.

Abstract:
This research is focused on mapping the geometries of surface and subsurface landforms and their relationship in the Niger Delta. Landforms on the surface are studied to improve our understanding of the spatial distribution of buried landforms. GIS techniques are applied to high resolution Landsat and SPOT imagery to map surface landforms, a necessary step in order to improve and better constraint subsurface modelling. Also, attributes from three dimensional seismic data are used to map buried landforms. Both techniques are focused on mapping the spatial distribution of landforms and analysis of their shape, size, orientation, connectivity and density. Results on the study of fluvial channels, point bars, braid bars, tidal channels, beach-barrier islands and spits are presented in this thesis. The updated map of the subarial Niger Delta covers an area of 70,000 km2. Tidal channel width increases exponentially toward the coast; in contrast the fluvial channel width decreases linearly downstream. Tidal channels are interconnected within a complex network. The tidal channels are wider in the East and West Flanks while in the centre they are narrower. Here, channel mouths are at a high angle with the coastline because of a combined effect of high sediment flux and longshore drift. Tidal channels are therefore grouped into four distinct zones; the West (Forcados River Zone), the Central (Nun River Zone), the East (Sombreiro River Zone) and the Far-East (Cross River Zone) based on their channel morphology and density. Each lobe is influenced differently by the interaction of fluvial, tidal and wave-related processes. This implies that it is appropriate to look at the Niger Delta as an amalgam of deltas geographically separated into four lobes. The morphology of the beaches also supports the considered reclassification, as they show distinct morphologies within each of the four lobes. Beaches are longer and wider on the eastern and western flanks and thin out towards the central lobe due to high sediment influx and wave reworking. Parallel channels form between scrolls and ridges and are prominent in areas where tidal influence does not extend far into the land. The correlation between the geometries of the surface and subsurface landforms is very strong and indicates that where subsurface details are missing, it is acceptable and reasonable to use surface information to make predictions about the subsurface. The result will help in constraining parameters used in modelling of geometric and dimensional properties of reservoirs and to better manage uncertainties, all elements relevant to the oil and gas industry.

Abstract:
The southern Chandeleur Islands are an ideal setting to study shoal evolution given their history of submergence and re-emergence. Here, numerical models shed light on the attendant processes contributing to shoal recovery/reemergence following a destructive storm event. Simulations of a synthetic winter storm along a cross-shore profile using Xbeach shows that convergence of wave-induced sediment transport associated with repeated passage of cold-fronts initiates aggradation, but does not lead to reemergence. A Delft3d model of the entire island chain shows that as these landforms aggrade alongshore processes driven by incident wave refraction on the shoal platform, backbarrier circulation and resulting transport become increasingly important for continued aggradation and eventual emergence. Aggradation magnitudes are a function of depth ranging from 2 – 10 mm per event (onset to recovery to near mean sea level). In the absence of big storms, this modest aggradation can be more than one meter in a few years.

Abstract:

Kongsfjordhallet is situated at 79° N on the North coast of Kongsfjorden, Spitsbergen.The landscape shows a large diversity of landforms and sediments and the aim of thisstudy has been to investigate the spatial distribution and temporal differences betweenthese landforms.The most prominent landform is interpreted as a lateral moraine dividing the area fromsoutheast to northwest. This is probably a sign of a standstill during the deglaciation ofan ice-sheet glacier tongue filling the fjord. The valley-glaciers at Kongsfjordhallet haveadvanced after this event and left end moraines on top of the lateral moraine. Largeamounts of meltwater have eroded parts of the Kongsfjordhallet, creating several fossilmeltwater channels that dissect the landscape. Erratic boulders of mainly gneiss type arescattered all over the landscape, as high up as 500 m a.s.l. In addition to the erraticboulders, a lot of allochthonous material is found incorporated in local material,especially as a diamict interpreted as till that covers large parts of Kongsfjordhallet.The till can likely be correlated to one of the diamict units in the cliff sections at theKongsfjordhallet coast. At present, two large ravines drain the area, moving water fromthe glaciers to the ocean and a beach is developing in the Southeast part of the area dueto ocean transgression. Landforms from two glacial events are found, one regional andone local. An episode of high sea-level as well as fluvial and mass-wasting activity afterthe deglaciation is also recorded. The formation of the landforms in the area is believedto be after the Last Glacial Maximum and into the Holocene, but no absolute dates areavailable.

Full text
Abstract:
Current riparian zone assessments focus on the morphological features of the stream channel and ocular vegetation measurements. This procedure fails to address the hydraulic features responsible for the floristic structure and composition of the riparian zone. We looked at how the geology and landforms function as drivers of groundwater and surface-water exchange. These can mitigate watershed processes via groundwater availability to shape riparian processes; e.g. discharge, seasonality. We hypothesized that groundwater surface-water exchange is a first order process and that it dictates riparian water availability and that the underlying geology and landform can serve as a tool to gain greater understanding of a properly functioning riparian ecosystem. We tracked groundwater surface-water exchange using wells, piezometers, water temperature, conservative tracer injections and solute conductivity on an alluvial fan in the Gallatin valley. Southwestern Montana Conservative tracer injection indicated 3% tracer losses over the 1.5km reach. Through spring and summer 2011 groundwater wells and piezometers indicated flashy transient shallow groundwater. Significant late growing season stream discharge (~300 l/s) and standard riparian monitoring assessments would suggest a larger floristic community than what is present at the site. These metrics together suggest a disconnection between the surface-water and groundwater ultimately limiting the extent of the riparian vegetation community. We further determined that the surface water is disconnected from the local groundwater table. We conclude that the lack of surface water - groundwater connectivity drives the floristic structure and character of the riparian zone. Skewed or inaccurate views of riparian functionality may occur because; the current assessment fails to address surface water - groundwater connectivity.

Abstract:
Wollaston Peninsula and most of southern Victoria Island comprise Palaeozoic carbonate lowlands, scarps, and tableland situated between rises and arches of underlying Precambrian sedimentary and igneous rocks. Quaternary sediments are hummocky, thick and ice-cored near escarpments where ice flow resistance, thrusting and meltwater concentrated glacial debris; thinner, streamlined drift occurs in lowlands. Quaternary sediments are mainly Late Wisconsinan in age. Glacial sediments predominate but surficial raised marine and periglacial sediments are noted. Fluvial modification of the landscape is minor. Many of the spectacular glacial landforms on Wollaston Peninsula are streamlined and indicate formation under thick, warm-based (i.e. free subglacial water) glaciers. A set of distinctive landforms, including ground moraine (with small moraines and marginal channels), hummocky moraine, lateral moraines, and streamlined forms, relates to varying flow conditions within one major glacial advance. Stratified drift within moraines indicates the importance of glaciofluvial processes in addition to ice action. Collectively, these landforms record ice-marginal retreat, marginal stagnation following compressional flow, surging, flooding and regional stagnation during deglaciation. Freeze-on and ice stagnation trapped extensive bodies of drift-rich ice in zones of hummocky moraine. Arborescent networks of narrow eskers record subglacial meltwater drainage beneath major ice lobes and long broad eskers record subaerial deposition by meltwater of mainly supraglacial derivation. Late glacial events are dated relative to the incursion of the sea during deglaciation of northwest areas of Wollaston Peninsula by about 12 000 BP. Active ice-marginal conditions existed just before 10 000 BP, during formation of the large Colville moraines. Ice downwasted in the area causing glacier thinning. Prominent ground-ice features include pingos, thermokarst scars, and debris-flow lobes. Ground ice occurs as massive icy bodies, ice-wedge ice, and buried pingo ice. Based on its setting in hummocky moraine, its stratigraphy, debris content, and isotopic composition, the massive ice is likely buried glacial ice. Landscape modification by thermokarst erosion has produced ubiquitous diamictons similar to till, and landforms similar to glacial forms. Thick ground ice bodies exist only above marine limit and the limits of streamlined landforms because permafrost degradation occurred below these limits. Widespread thaw slumps and large-scale thermal contraction cracks also indicate ice-cored terrain.

Abstract:
ERDC-Geo is a surface erodibility parameterization developed to improve dust predictions in weather forecasting models. Geomorphic landform maps used in ERDC-Geo link surface dust emission potential to landform type. Using a previously generated southwest United States landform map as training data, a classification model based on machine learning (ML) was established to generate ERDC-Geo input data. To evaluate the ability of the ML model to accurately classify landforms, an independent reference landform data set was created for areas in the Chihuahuan Desert. The reference landform data set was generated using two separate map-ping methodologies: one based on in situ observations, and another based on the interpretation of satellite imagery. Existing geospatial data layers and recommendations from local rangeland experts guided site selections for both in situ and remote landform identification. A total of 18 landform types were mapped across 128 sites in New Mexico, Texas, and Mexico using the in situ (31 sites) and remote (97 sites) techniques. The final data set is critical for evaluating the ML-classification model and, ultimately, for improving dust forecasting models.
