U radu se analiziraju promjene žala u uvalama Rašćine, Juto i Kutleša u posljednjih četrdeset godina. Razmotreni su osnovni prirodni čimbenici njihova oblikovanja, a osobita pozornost posvećena je ...antropogenim utjecajima koji su taj prirodni razvoj poremetili te načinu na koji obalni sustav reagira na antropogene modifikacije. Izgradnja dužobalnih konstrukcija, kao i odlaganje materijala u neposrednoj blizini obale i u more zbog naglog širenja obližnjih naselja i razvoja turizma, uzrokovali su višak sedimenta u moru koji uzrokuje progradaciju i eroziju pojedinih segmenata žala.
The scientific monograph ('Palaeofloods in karstic Ljubljanica River Catchment') presents a research on palaeofloods in the main water confluence in the Ljubljanica River Catchment, namely the area ...between the Pivka Basin, Cerknica Karst Polje, and Planina Karst Polje. Several geomorphological forms genetically related to floods have been identified, e.g. floodplains, river terraces, corrosion notches on cave walls, as well as laminated fine-grained sediments. Since they were found at higher altitudes than the present floods reach, they were considered as palaeoflood features. Morphometric analysis of the studied geomorphological forms was used to determine the volume of palaeofloods and their altitudinal range. The hydrometric characteristics of the palaeofloods where calculated by computer modelling. Petrological analyses of fine-grained sediments from the surface and caves were used to determine the origin of sediments and their settling velocities, hence to prove their flood origin. Furthermore, morpho-chronological analyses with radiometric methods 14C and U-Th on flowstones interlaying with flood sediments where carried out. The results show that the volume and altitude of palaeofloods throughout the study area fairly exceeded the highest known recent floods.
Pri multimodalnem pristopu k uravnoteženi zastopanosti oblik javnega in zasebnega prevoza tirnični sistemi prispevajo k rešitvi prometnih težav v modernih mestih. Njihovo uvajanje v urbane enote ...omogoča urbano transformacijo, ki lahko z racionalno rabo energije, zmanjšanjem hrupa in onesnaženosti zraka, zmanjšanjem prometne gneče, socialno integracijo na javnih mestnih prostorih, funkcionalnostjo urbanih enot in privlačnostjo urbane oblike prispeva k mestu, ki je trajnostno in prijazno za bivanje. Prostorske elemente tirničnih sistemov je mogoče spraviti v ustrezno razmerje z urbanimi elementi in elementi reliefa. Z oblikovanjem odnosov med temi elementi na ravni javnih mestnih prostorov, in sicer na podlagi arhitekturnih načel, je mogoče oblikovati funkcionalne urbane enote posebne oblike in urbane zasnove. Cilj dela je ugotoviti, kako je mogoče spraviti navedene elemente v prostorski odnos, da bi javni mestni prostori, ki vsebujejo tirnične sisteme, prispevali k funkcionalnosti in privlačnosti za bivanje prijazne in trajnostne urbane oblike. Cilj je tudi ugotoviti, kako konfiguracijo terena, z vsemi njenimi elementi, spraviti v proces digitalnega projektiranja urbanih prostorov, ki vsebujejo tirnične sisteme ; In the multimodal approach to a balanced representation of public and private transportation, rail systems contribute to the solution to the problem of traffic in modern cities. The introduction of these systems in urban units enables the creation of urban transformations that can contribute to livable and sustainable cities, through the rational use of energy, reduction of noise and air pollution, reduction of traffic jams, social interactions in public spaces, functionality of urban totalities and the attractiveness of the urban form. Spatial components of rail systems can be related with the urban elements and the elements of landscape. Through relating these elements at the level of public spaces, and based on architectural principles, it is possible to create functional urban totalities of specific form and urban design. The objective of this study is to determine the way in which these elements can be spatially related in order to enable the contribution of public areas containing rail systems to the attractiveness of livable and sustainable urban form. The objective is also to establish criteria based on which the configuration of terrain with all its elements will be introduced into the process of designing urban spaces that include rail systems.
A phytosociological survey of a woodland located in the central part of Umbria (Central Italy) was carried out using the Braun-Blanquet method: 80 relevés were classified through cluster analysis. ...Nine forest syntaxa were reported and three subassociations (Erico arboreae-Quercetum cerridis lathyretosum veneti, Aceri obtusati-Quercetum cerridis arbutetosum unedonis and Cyclamino hederifolii-Quercetum ilicis quercetosum cerridis) were typified. Topographic data (altitude, aspect, slope, morphology) and pedological data (soil pH, texture and depth) were collected and a synecological analysis of syntaxa was performed. In order to understand the relation between environmental factors and plant communities, a Canonical Correspondence Analysis was run. The results showed soil parameters (pH, texture and depth) and altitude as the main ecological factors explaining the distribution of plant communities in the study area. The combination of topographic factors (aspect, morphology and slope angle) influences, by contrast revealed the distribution of forest syntaxa within homogeneous geo-pedological and bioclimatic conditions.
Izvedli smo fitosociološko raziskavo gozdov v srednjem delu Umbrije (srednja Italija) z Braun-Blanquetovo metodo: 80 popisov smo uvrstili s klastrsko analizo. Obravnavamo devet gozdnih sintaksonov in opisali smo tri subasociacije (Erico arboreae-Quercetum cerridis lathyretosum veneti, Aceri obtusati-Quercetum cerridis arbutetosum unedonis in Cyclamino hederifolii-Quercetum ilicis quercetosum cerridis). Zbrali smo topografske (nadmosrska višina, ekspozicija, naklon, morfologija terena) in pedološke podatke (pH, tekstura in globina tal) in naredili sinekološko analizo sintaksonov. Za pojasnitev povezave med rastiščnimi dejavniki in rastlinskimi združbami smo naredili Canonical Correspondence Analysis. Rezultati kažejo, da so dejavniki tal (pH, tekstura in globina) in nadmorska višina glavni rastiščni dejavniki, ki pojasnjejo razširjenost rastlinskih združb v obravnavanem območju. Kombinacija topografskih dejavnikov (ekspozicija, morfologija reliefa in naklon) je odločilna za pojavljanje gozdnih sintaksonov v homogenih geopedoloških in bioklimatskih razmerah.

In 1924, the Triglav Lakes Valley was designated a protected area, which is today part of the central area of extensive Triglav National Park. The lakes give a special character to the valley, which ...also stands out for its other natural features. In terms of nonliving nature, this volume presents some of the valley’s geological, geomorphological, and hydrological characteristics, and, in terms of living nature, it presents its vegetation, focusing on botanical characteristics and forest. The volume also discusses the human presence and its impact on the appearance of the landscape.
Za razliko od dobro raziskane pleistocenske poledenitve so periglacialni pojavi v Sloveniji slabo preučeni, saj zaradi prevlade karbonatnih kamnin v visokogorju niso posebno opazni. Drugače je na ...Pohorju, zgrajenem iz magmatskih in metamorfnih kamnin, ki zaradi premajhne višine ni bilo poledenelo, pač pa so bili aktivni periglacialni procesi. V članku so prvič predstavljene nekatere periglacialne oblike na Pohorju, predvsem nivacijske kotanje v vršnih delih, in krnica Jezerc, v kateri je ob višku poledenitve obstajal doslej nepoznan manjši ledenik.
Predstavljene so meritve erozijsko-denudacijskih procesov v porečju Dragonje. Meritve so obsegale površinsko spiranje na treh različnih rabah tal, umikanje strmih golih flišnih pobočij, premikanje ...gradiva po erozijskem jarku in kemično denudacijo v porečju. Meritve so potekale od februarja 2005 do maja 2006. Namen članka je opozoriti na hitrost nekaterih geomorfnih procesov, zaradi katere bi bilo treba bolj poudariti njihov pomen pri oblikotvornosti površja.
Prispevek skuša osvetliti različne vrednote reliefnih oblik kot sestavnega dela geomorfološke naravne dediščine ter pomagati pri uveljavljanju termina geodiverziteta v Sloveniji. Članek predstavi ...razloge, zakaj vrednotiti geodiverziteto, katerim sledi razprava o specifičnih vidikih naravnih vrednot: intrinzičnih, kulturnih, estetskih, socialno-ekonomskih, funkcijskih, geosistemskih, znanstvenoraziskovalnih in izobraževalnih.
Članek predstavlja možnosti vizualnega preučevanja arheološkega potenciala ali arheološke valorizacije kraškega območja južnega dela Ribniške Male gore. Raziskovano območje je znano po jamskih ...najdiščih Lisičja jama in Koblarska jama. Do sedaj niso bili identifi cirani ostanki prazgodovinskih naselbin na površju. S terenskim preučevanjem in s pomočjo GIS-ov avtorja poskušata opredeliti potencialne možnosti za zgodovinsko poselitev na preučevanem območju. Drugi vidik njunih raziskav predstavlja sistematično pregledovanje horizontalnih jam na Koblarskem hribu. S preučevanjem naravnih, predvsem geomorfnih, in antropogenih procesov ter oblik v jamskih okoljih ugotavljata možnost zgodovinske rabe jam.
