Special Issue Information
Dear Colleagues,
Geothermal resources are valuable clean and recyclable renewable resources with great utilization value, and can be widely used in various fields such as power generation, heating, physiotherapy, greenhouse, and aquaculture. In their natural state, geothermal resources have the characteristics of deep burial, slow groundwater recharge, and slow regeneration.
In order to maintain the pressure of thermal storage, avoid the continuous decline of water levels caused by the long-term large-scale exploitation of geothermal water, and realize the sustainable utilization of geothermal water, the surface’s clean water source or used geothermal tail water is reinjected into the thermal reservoir through the recharge well, which can achieve the purpose of increasing the mining output of geothermal water, alleviating the continuous decline in the groundwater level and reducing the environmental pollution caused by the direct discharge of geothermal fluid. It is an effective means to ensure the sustainable development and utilization of geothermal energy.
Although geothermal water reinjection can increase the artificial supply source, replenish the consumed groundwater resources in a timely manner, and play a role in improving the geothermal mining output, maintaining the pressure of heat storage and alleviating the decline in the groundwater level, etc., disorderly and excessive geothermal reinjection may accelerate the emergence of "thermal breakthrough", resulting in irreversible changes in the geothermal field, temperature field, water flow field, and chemical field. Therefore, it is necessary to strengthen the dynamic monitoring of geothermal water and the study of its dynamic characteristics during reinjection.
This Special Issue is organized into three sections:
Section 1: The origin of geothermal water. The study on the origin of geothermal water can directly explain the characteristics of the recharge, runoff, and discharge of geothermal water, which is very important for the monitoring of geothermal water;
Section 2: Hydrochemical research. The dynamic monitoring and analysis of the chemical composition of geothermal water is very important for understanding changes in the chemical composition of geothermal water;
Section 3: The monitoring of fractured rock aquifers. By monitoring fractured aquifers and strengthening the dynamic monitoring of geothermal water and the study of its dynamic characteristics, the characteristics of geothermal water’s temperature field, flow field, and chemical field can be dynamically understood.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
