V Slovenji se povprecna temperatura zraka v drugi polovici 20. stoletja in na zacetku 21. stoletja zvisuje, medtem ko kolicina padavin upada. Manjse je tudi stevilo dni s snežno odejo, zmanjsuje pa se tudi visina snežne odeje. Spremembe kolicine padavin v povezavi s spremembami rabe tal vplivajo na spremembe pretokov rek, ki v zadnjega pol stoletja beležijo upadajoc trend pretokov oziroma zmanjsanje vodnih kolicin. V clanku so predstavljeni trendi temperatur in padavin ter trendi pretokov rek v Idrijskem hribovju med letoma 1961 in 2010. Rezultati na obravnavanem obmocju kažejo narascanje letne temperature, padanje kolicine padavin in stevila dni s snežno odejo, v upadanju pa so tudi letni pretoki rek. In Slovenia, the average air temperature is since the second half of the 20th century and at the beginning of the 21st century increasing, while the amount of precipitation decreases. The number of days with snow cover is also lower, and the height of the snow cover decreases. Changes in the amount of precipitation associated with changes in land use affect the changes in river discharges, which in the last half century have recorded a downward trend or a decrease in water quantities. The article presents trends in temperatures and precipitation and trends in river discharges in the Idrija hills between 1961 and 2010. The results show the increase in the annual temperature, the drop in precipitation and the number of days with snow cover, as well as in river discharges.

Geografski institut je leta 1946 ustanovila Slovenska akademija znanosti in umetnosti in ga leta 1976 poimenovala po najvecjem slovenskem geografu, akademiku Antonu Meliku (1890–1966). Od leta 1981 je sestavni del Znanstvenoraziskovalnega centra Slovenske akademije znanosti in umetnosti (ZRC SAZU). Zdaj je s 33 raziskovalci najvecja slovenska geografska ustanova. Izdaja sest periodicnih znanstvenih publikacij: revijo Acta geographica Slovenica in pet knjižnih zbirk. Njegovi raziskovalci se ukvarjajo predvsem s temeljnimi in z uporabnimi geografskimi raziskavami Slovenije in njenih pokrajin. Pripravljajo temeljne geografske knjige o Sloveniji, sodelujejo pri stevilnih domacih in mednarodnih projektih, organizirajo znanstvena srecanja, izmenjujejo znanstvene obiske, izobražujejo mlade raziskovalce, poucujejo na fakultetah.The Geographical Institute was founded in 1946 by the Slovenian Academy of Sciences and Arts. In 1976 it was named after Slovenia’s greatest geographer, academy member Anton Melik (1890–1966). Since 1981, the Institute has been one of the members of the Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU). With 33 researchers the Institute is now the largest Slovenian geographical institution. The institute issues six scientific periodical publications: the Acta geographica Slovenica journal and five book series. The Institute researchers are engaged in basic and applied geographic research on Slovenia and its landscapes. They prepare basic geographical books on Slovenia, participate in numerous national and international projects, organize scientific conferences, participate in professional exchanges, train junior researchers, and teach at universities.

V clanku predstavljamo hidro-geomorfne procese, ki so povezani z naravnimi in umetnimi pregradami. Ob zajezitvah, ki nastajajo za pregradami, prihaja zaradi razlicnih vzrokov, kot je nihanje vodne gladine, do proženja zemeljskih plazov in skalnih podorov. Taksni pojavi lahko povzrocijo prelitje ali podrtje naravnih pa tudi umetnih pregrad. V tem oziru posebej poudarjamo Vajontski zdrs, ki je zaradi cloveskega vzroka, velikosti in katastrofalnih posledic eden bolj znanih tovrstnih pojavov v Evropi. Predstavljamo tudi povecini spregledane pojave v Sloveniji ter nekaj vecjih pojavov po svetu. The article presents hydro-geomorphic processes associated with natural and artificial dams. Landslides and rockfalls are triggered behind the dams due to different causes, e.g. fluctuation of the water level. Such phenomena can cause overspilling or demolish natural and artificial dams. In this regard, the article presents the Vaiont rockslide, which is due to human-related causes, its size and the catastrophic consequences one of the most well-known phenomena in Europe. Some other examples from the world and in Slovenia are presented.

Za obmocje Slovenije obstaja dolgoleten niz letalskih posnetkov ciklicnega aerofotografiranja Slovenija (CAS). Njihova uporaba je bila v geografiji med drugim povezana s spremembami rabe tal, s preucevanjem degradacije okolja, pa tudi za ugotavljanje nekaterih naravnogeografskih sprememb v pokrajini, na primer za ugotavljanje sprememb ledenikov ali za premikanja recnih strug. V clanku predstavljamo uporabnost CAS za spremljanje intenzivnosti pobocnih procesov. Z njihovo pomocjo smo izmerili velikost dveh skalnih podorov: podor slapu Cedca v Kamnisko-Savinjskih Alpah ter odlom na pobocju Glave pod Triglavom. Poleg tega smo ugotavljali reliefne spremembe na meliscu Birski plaz pod Velikim vrhom na Kosuti ter v hudourniski dolini potoka Suhelj v Zgornjesavski dolini.A set of cyclical aerial photogrammetric measurements of Slovenia (CAS) taken over the course of many years is available. Among other things, their use in geography has been connected with exploring changes in land use, studying environmental degradation, and determining specific physical geographical changes in the landscape, such as changes in glaciers and river beds. This article presents the usefulness of CAS for monitoring the intensity of slope processes. CAS stereoimages were used to measure the size of two rockfalls: one at Cedca Falls in the Kamnik-Savinja Alps and one on the slopes of Mt. Glava below Mt. Triglav. Also studied were terrain changes on the Birski plaz talus below Mt. Veliki Vrh on the Kosuta Massif in the Karavanks, and in the torrent valley of Suhelj Creek in the Upper Sava Valley.
