“…H Gin = ρ w c p G in (T Gin − T L ) (10) where ρ w is the groundwater density, c p is the specific heat (J/kg/K) of water and T L is the representative lake water temperature (K) (273.15 K = 0 • C + 273.15). Here, if T L is supposed to be the bottom water temperature 275.45 K (2.3 • C) and 275.25 K (2.1 • C) averaged over the periods of 2019-2020 and 2020-2021, respectively, T Gin is given at 278.75 K (5.6 • C) and 279.05 K (5.9 • C), respectively.…”

“…This means that the groundwater inflow to Okama in the ice-covered period is smaller than that in the rainfall season. For example, if G in = 0.010 m 3 /s at the calculated H Gin = 2.5 and 2.9 W/m 2 , Equation (10) gives T Gin = 279.45 K (6.3 • C) and 279.85 K (6.7 • C), respectively. Hence, the calculated temperatures 5.6 • C and 5.9 • C appear to correspond to the lowest values in the ice covered period.…”

Hydrological and Chemical Budgets of Okama Crater Lake in Active Zao Volcano, Japan

et al. 2022

The Okama Crater Lake is located in the highly active Zao Volcano on the boundary of Miyagi and Yamagata Prefectures, Japan. At present, the lake stays relatively calm with neither bubbling, steaming nor gas smell at a pH of 3.2–3.4, though the lake did change color with steaming from the water surface in 1939 as the result of one of Zao’s volcanic activities. In order to clarify the geothermal effect on Okama and the groundwater flow system below or around Okama, field observations were performed in 2019 and 2020. Groundwater inflow and outflow in Okama were separately evaluated by estimating the hydrological and chemical budgets of the lake, based on the hydrometeorology, water temperature and river inflow measured in the field. The average groundwater inflow and outflow were estimated at 0.012 m3/s and 0.039 m3/s during the non-rainfall periods of 2020, respectively. A surplus of groundwater outflow makes the lake level consistently decrease during non-rainfall periods or the completely ice-covered season. In the completely ice-covered periods, the water temperature consistently increased at 0–15 m above the lake bottom, which is probably due to thermal leakage from a hydrothermal reservoir below the lake bottom. The heat fluxes averaged over December 2019–April 2020 and December 2020–March 2021 were calculated at 2.5 and 2.9 W/m2, respectively. A coupling between the estimated groundwater inflow and the calculated geothermal heat flux was used to evaluate the temperature of inflowing groundwater.

“…With the maturity of GFS theory, people actively apply Tothian theory to practical hydrogeological work. For example, people in countries such as Canada, the United States, China and Japan have widely used GFS theory in hydrogeological survey and mapping, water source and sewage discharge site selection, ecosystem protection and so on; and fruitful theoretical and practical results were achieved (Cloutier et al, 2006;Palmer et al, 2006;Han et al, 2009;Toth, 2009;Lei et al, 2012;Zhang et al, 2015;Ono et al, 2019). By means of isotopes, it was found that there was not only a recharge relationship between surface water and groundwater, but also a GFS at the bottom of the ocean (Krall et al, 2017;Xu et al, 2018b;Danish et al, 2020).…”

Tóthian theory refers to the gravity driven groundwater flow system (GFS) theory represented by Tóth, which mainly expounds the driving and distribution law of groundwater. The establishment and development of this theory not only deepened people’s understanding of the driving and distribution law of groundwater, but also greatly promoted the study of groundwater chemical evolution (GCE). Modern GCE research is mostly based on Tóthian theory, characterized by combining with advanced scientific and technological means. Based on the clue of time, this paper is divided into two parts. The first part mainly summarizes the establishment and development of Tóthian theory, including the exploration of groundwater driving force and distribution form by hydrogeologists before Tóthian theory, and the enrichment, development and application of Tóthian theory by geologists after its establishment. The second part mainly combs the main theories and application progress of GCE mechanism research, including the main theories and findings of GCE research before the emergence of Tóthian theory, as well as the research progresses of GCE after the emergence of Tóthian theory. With the flow of groundwater in GFS, groundwater undergoes continuous chemical evolution, which eventually leads to the transformation of hydrochemical types and the gradual increase of total dissolved solids (TDS). The distribution of GFS and GCE complement each other. The distribution of GFS directly determines the model of GCE, and the results of GCE also play a certain role in the distribution of GFS. GCE mainly includes dissolution, precipitation, cation exchange and adsorption, which is affected by the physical and chemical conditions of permeable media, organic matter content and microorganisms. GCE has the characteristics of universality, sustainability and diversity. With the increasing global population and the progresses of science and technology, the impact of human life, industrial and agricultural production on groundwater is deepening. The aggravation of pollution directly changes the chemical compositions of groundwater, resulting in changes of the law of GCE.

“…Investigations into groundwater flow systems, as proposed by József Tóth [2][3][4][5][6], have been reported in several countries, e.g., Australia [12], Canada [13], China [14][15][16], Hungary [17,18], Japan [19]. In Mexico, local studies on the application of the groundwater flow systems have been carried out by Carrillo-Rivera et al [20,21], Huizar-Álvarez et al [22,23], Carrillo-Rivera et al [24][25][26], Cardona et al [27], and Ouysse et al [28].…”

The dynamics of the underground part of the water cycle greatly influence the features and characteristics of the Earth’s surface. Using Tóth’s theory of groundwater flow systems, surface indicators in Mexico were analyzed to understand the systemic connection between groundwater and the geological framework, relief, soil, water bodies, vegetation, and climate. Recharge and discharge zones of regional groundwater flow systems were identified from evidence on the ground surface. A systematic hydrogeological analysis was made of regional surface indicators, published in official, freely accessible cartographic information at scales of 1:250,000 and 1:1,000,000. From this analysis, six maps of Mexico were generated, titled “Permanent water on the surface”, “Groundwater depth”, “Hydrogeological association of soils”, “Hydrogeological association of vegetation and land use”, “Hydrogeological association of topoforms”, and “Superficial evidence of the presence of groundwater flow systems”. Mexico’s hydrogeological features were produced. The results show that 30% of Mexico is considered to be discharge zones of groundwater flow systems (regional, intermediate, and recharge). Natural recharge processes occur naturally in 57% of the country. This work is the first holistic analysis of groundwater in Mexico carried out at a national–regional scale using only the official information available to the public. These results can be used as the basis for more detailed studies on groundwater and its interaction with the environment, as well as for the development of integrative planning tools to ensure the sustainability of ecosystems and satisfy human needs.
