Abstract The analysis of the geomorphological features developed over a given area contributes to the knowledge of the processes that intervened in the evolution of the landscape, helping to reliably understand their interaction with the surface and underground water resources. The headwaters of the Rio del Oro are in the Sierra de Famatina, which is located in the north center of La Rioja Province. Based on the collection and analysis of the bibliography and images of the study area and field work, several geomorphological features of the area were identified and characterized, in order to establish links with their locations and determine the agents and processes that acted in landscape modeling. In turn, a hydrological description was made to broaden the knowledge of the water resource of this area, which is essential according to the arid climatic conditions. Despite the aforementioned context, fluvial activity stands out as one of the main relief modelers, considering the neotectonics and the Quaternary climate changes as notable factors in evolution.

阿根廷拉里奥哈省里奥德尔奥罗盆地的水文和地貌特征

摘要 对给定区域发展的地貌特征的分析有助于了解干预景观演变的过程，有助于可靠地了解它们与地表和地下水资源的相互作用。Rio del Oro 的源头在位于拉里奥哈省北部中心的法玛蒂纳山脉。基于对研究区域和实地工作的参考书目和图像的收集和分析，识别和表征了该区域的几个地貌特征，以建立与其位置的联系并确定在景观建模中起作用的代理和过程。反过来，进行了水文描述以拓宽对该地区水资源的了解，根据干旱的气候条件，这是必不可少的。尽管有上述背景，但考虑到新构造运动和第四纪气候变化是进化中的显着因素，河流活动作为主要的救济建模者之一脱颖而出。
