The fluvial system can be characterized from the application of geomorphological indicators. These allow understanding the dynamics of the system as well as carrying out a status diagnosis for good management. The aim of this work was to apply a group of geoindicators to diagnose and monitor the environmental status of the Oro basin (38° 4' 56.9"S 61°56' 24.17"W), Argentina. The geoindicators were grouped according to the application objective (diagnosis and monitoring) and the time scale (long, medium and short term). The field work was carried out during the period 2019 - 2021, which was the main input of information. The application of geoindicators in the medium and long term allowed the environmental characterization of the basin and recognition of the most important characteristics in terms of its fluvial dynamics, highlighting the variability of rainfall, which when it occurs in an extreme way, due to the morphometric characteristics of the basin, favors the occurrence of stream flooding events. In the short term, they allowed the identification of those indicators to be monitored to ensure optimal hydrogeomorphological quality, mainly in the riparian areas, which resulted in the highest degree of transformation.

The contribution of historical hydrogeomorphology in areas lacking hydrographic information or reliable geomorphological studies represents an interesting complementary tool to delimit potentially floodable spaces. This work aims at determining floodable areas through the historical hydrogeomorphological approach. The unit of analysis taken is the San Bernardo stream basin which is located in the mountain range system of Ventania, Buenos Aires (Argentina). The methodology used is based on different methods and techniques (hydrographic, geomorphologic, biogeographic) which, by complementing one another, allow for the zoning of the flood plain. The flooding events occurring in this area are linked to torrential rainfall events. The consequences range from material damage, to loss of infrastructure and even fatalities, in some cases.

The urban growth of Bahía Blanca city has intervened the northern periurban area with the consequent modification of the natural landscape, in particular the drainage network. Geo-morphological maps are instruments that make possible a temporal analysis and facilitate the visualization of processes and forms of the surface. The GIS software facilitates the analysis of the changes produced in the natural environment due to urban development. The aim of this work is to study the mutual implications between the geo-morphological dynamics and the urbanization process in the northern periurban area of Bahía Blanca city. The identification of geoforms and processes was carried out on the basis of geological documents of the area, visual analysis of high resolution satellite images (2009 and 2015) and field control. A geographic database was implemented using Arc- GIS 10® that enables temporal analysis and the development of thematic cartography. Natural areas modified by urbanization and new periurban areas affected by hydro-geo-morphological dynamics were identified from a quantitative and qualitative cartographic analysis.

The wind is one of the elements of the weather that most affect the population in Bahia Blanca city, predominating most part of the year. Due to its high temporal and spatial variability is essential to know their maximum speeds, directions and predominant distribution. The aim of this paper is to analyze winds behavior in its two dimensions, speed and direction, in suburban north part of Bahia Blanca city. Recorded data were analyzed by two weather stations installed in the study area for the period March 2011-September 2011. It was obtained media values of speed, frequent directions, maximum gusts and was characterized the seasonal, monthly and daily behavior. [ABSTRACT FROM AUTHOR]

The study area corresponds to the basin of "El Belisario" stream, a small valley among mountains with a surface of 26 km², located in the Ventania System. The location determines the presence of social and physical elements which constitute a high environmental vulnerability facing different kinds of threats such as massive fires and avenue phenomena of a cyclic character and marked seasonal concentration. The aim of this work is to establish links between the occurrence of avenue processes and the variation of water availability in "El Belisario" basin. Newspaper articles were gathered, annual and interannual water balances were made and environmental characteristics, which favour the occurrence of these events, were analyzed. It should be mentioned that the frequency of these phenomena is low; however, its magnitude has highly harmful consequences for the population. Important economical losses are generated, owing to the negative impact on resources-risking human lives and facilities. That is why understanding the dynamics of occurrence of these phenomena is necessary for improved local development and management of resources as well as for the watering process.

Building risk spaces differ according to the history of the urban development and the environmental context of each city. The aim of this work is to analyze historical-territorial periods that generated the construction of flood risk areas in the city of San Carlos de Bariloche, Río Negro, Argentina. The Dagwood Sandwich methodology was applied to analyze the urbanization and its transformations over time and the role played by the environment and the impacts caused by society. Correlations were observed within six historical-territorial crosscutting moments at different scales (local, provincial, national and international) and the development of exposed spaces to different dangers. This methodology allows identifying and acknowledging the current and historical environmental situation, in order to forecast possible trends of urban expansion and the generation of new flood-risk territories.
