摘要

利用从地中海流域提取的地表水,即智利中部的马塔基多河,评估了水化学的时空变化。控制流域水化学动态的过程是通过评估水文事件(降雨、河流流量、径流率)、物理化学性质和河流主要离子浓度/分布之间的关系来确定的。在雨季,主要离子水平主要受风化(降雨)控制。在干旱期,海水入侵是控制水化学的主要因素。异常高的氯和硫酸盐浓度表明进入盆地的离子有人为来源。因此,流域内工业和农业活动造成的污染在数量上可能是重要的,在今后对这一领域的研究中应予以考虑。

Temporal and spatial changes in surface water chemistry in a Mediterranean river of central Chile: The case of the Mataquito river (~35°S)
Spatial and temporal changes in water chemistry were evaluated using surface water extracted from a Mediterranean river basin, i.e., The Mataquito River, central Chile. The processes that control water chemistry dynamics in the basin were determined by assessing the relationship between hydrologic events (rainfall, river flow, runoff rates), physical-chemistry properties, and major ion concentrations/distributions along the river. During the rainy period, major ion levels were controlled predominantly by weathering (rainfall). During the dry period, seawater intrusion was the main factor controlling water chemistry. Unusually high chlorine and sulfate concentrations suggested anthropogenic sources of the ions entering the basin. Thus, pollution from industrial and agricultural activities in the basin might be quantitatively important and should be considered in future studies of this area.

期刊介绍: Published by the Mexican Institute of Water Technology, Water Technology and Sciences (Tecnología y ciencias del agua) is a highly specialized journal which reflects two important characteristics: The interdisciplinary nature of its articles and notes. The international scope of its authors, editors, reviewers, and readers. It constitutes the continuity of the journal Irrigación en México (Irrigation in Mexico) (1930-1946); Ingeniería hidráulica en México (Hydraulic Engineering in Mexico) (1947-1971); Recursos hidráulicos (Hydraulic Resources) (1972-1978), and Ingeniería hidráulica en México, second period (1985-2009). The journal is aimed at researchers, academics, and professionals who are interested in finding solutions to problems related to the water. The journal’s contents are interdisciplinary and contain previously unpublished articles and notes that offer original scientific and technological contribution that are developed in the fields of knowledge related to the following disciplines: Water and energy. Water quality. Hydro-agricultural sciences. Political and social science. Water management. Hydrology. Hydraulics.
