Iași Municipality as other urban areas around the world has a long history of landslide activity which needs to be studied considering the urban sprawl. We performed a first landslide susceptibility modeling for Iași Municipality based on the AHP method using weights given by expert judgements regarding the influence of preparatory and conditional landslides factors (slope, ruggedness, lithology, historic landslide density and hydrogeology) and weights given by the historic landslide density over the factors.

Ground deformations are the result of interactions between terrain and various processes. Their identification and monitoring becomes an important step as they can provide insights about Earth’s dynamics or process triggering conditions. This paper aims to show the potential use of Sentinel-1 SAR images to identify ground deformations induced by neotectonics. Hence, we applied PS-InSAR stacking technique on Sentinel-1 ascending dataset in the area of Focșani basin, Eastern Romania. High density of PS obtained in populated areas allows the detection of tectonic fractures.

SRTM1 Digital Elevation Model for many mountain ranges in Romania were processed to provide slope gradient distributions for each 50 m band of altitude. The effects of cirques are seen in an increase in standard deviation of gradient, and a spread in all percentiles, especially an increase in the 95th, at relevant altitudes. Otherwise, variations in median gradient with altitude differ between ranges, and do not show the general increase found in the Alps below cirque floor altitudes by several authors.

SRTM data is still one of the most used data in geosciences for various purposes: geomorphometric analysis, environmental covariate modelling or geomorphic change detection. Although high resolution national/regional DEMs exist, very often accessing them is expensive, or their coverage is not complete over specific areas (only floodplains or cities are covered). Because of this SRTM still remains the best choice when elevation data is needed for regional/national or global areas.

As a tribute for a great romanian geomorphologist we list his biography and his published materials, and were we have access and license to publish, we also deliver the .pdf version of the document.

Flusskanäle sind Landschaftsformen, die von fließenden Gewässern geschaffen werden.
Im digitalen Format können die Flusskanäle als Kanäle oder als Polygone dargestellt werden.
Für ihre geomorphometrische Analyse ist es notwendig, die mittlere Linie des Flussbettes zu erstellen. Um die mittlere Linie des Flussbettes aus der Polygon-Topologie zu erzeugen, muss sie in eine Linie und dann in Punkte umgewandelt werden, wobei sich diese in einer bestimmten Entfernung füllen.
Unter Verwendung von Thiessen-Polygonen werden Thiessen-Polygone verwendet.
