  of Italy\, Research Institute for Geo-Hydrological Protection (CNR-IRPI)\
 , Padova\, Italy.\n\nIn recent years\, the intensification of the effects 
 of climate change has led to an increase in the frequency and intensity of
  extreme weather events\, making the territories increasingly vulnerable. 
 In this context\, watershed management and monitoring are playing an incre
 asingly central role in mitigating hydro-geological risk\, which can be re
 duced through effective and sustainable interventions. Nowadays\, Remote S
 ensing data combined with analysis in GIS environments are fundamental too
 ls to support these activities. However\, these technologies are not yet w
 idely widespread or user-friendly\, as the available tools are diverse and
  require specific expertise\, making it difficult to standardise workflows
  and obtain comparable results. To address these limitations\, the Univers
 ity of Udine\, in collaboration with CNR IRPI\, has developed a plugin for
  the QGIS software designed to support hydrological\, geomorphological and
  multi-temporal analysis of Digital Elevation Models (DTMs). \nThe develop
 ed plugin “HydroGeomorphology Tools for QGIS”\, includes several funct
 ionalities such as: i) exploiting the Kinematic Local Excess Model (KLEM) 
 distributed hydrological model\, to simulate the hydrological response of 
 catchments\, with particular reference to rainfall-runoff transformation p
 rocesses during flood events\; ii) useing DTMs to automatically derive cat
 chment boundaries\, flow directions\, upstream catchment areas\, channel n
 etworks\, and design hydrographs\; iii) integrating existing tools for geo
 morphological and multi-temporal analysis\, enabling the calculation of th
 e Connectivity Index (IC) and DoD (DTM of Difference\; i.e. the quantifica
 tion of erosion and deposition volumes by comparing DTMs acquired at diffe
 rent times). A additional module is dedicated to supporting the survey and
  management of the Torrent Control Structures: through morphological analy
 sis of the DTM and the longitudinal channel profiles\, the plugin supports
  the identification of potential structures along the channel network. \nT
 he plugin is distributed under an open-source licence to encourage its wid
 espread use and promote the standardisation of workflows in the hydro-geom
 orphological field. It is organised into five modules – Connectivity\, G
 eomorphology\, Hydrology\, Multi-temporal DTMs Analysis and Torrent Contro
 l Structures DB Manager – each of which incorporates the functionalities
  described above. \nThis work highlights how the development of open-sourc
 e tools\, such as the plugin presented here\, can help to support decision
 -making processes related to land management\, making advanced methodologi
 es accessible to those working in such contexts. In particularly vulnerabl
 e environments\, as mountainous areas\, such tools enable planning and man
 agement decisions to be made in a more informed manner\, helping to optimi
 se the use of economic resources towards effective and targeted interventi
 ons.\n\nAcknowledgement: This work was funded by the European Union - Next
