The scope of this Special Issue is to gather outstanding applied analyses of coupled THMC processes in fractured geological media, specifically focusing on coupled processes and challenges in deep underground tunneling, mining and nuclear waste disposal, as well as other subsurface activities involving underground excavations. The topics of the Special Issue include, but are not limited to:
Coupled processes and challenges in deep underground tunneling and underground construction, including rock bursts
Coupled THMC processes associated withgeologic nuclear waste disposal in various host rocks (e.g. crystalline, clay and salt)
Development of EDZ under THMC conditions
Laboratory and field measurements of coupled processes in fractured/fracturing media underground research laboratories
Short-term vs. long-term effects
Interaction between coupled processes, geological settings and heterogeneities
Coupled processes relevant in deep mining, including mining induced seismicity
Multi-scale effects in fractures

Virtual Special Issue on Geoheritage in Africa: Potential, Assessment, and Conservation
The Journal of African Earth Sciences has an interest in promoting research in geoheritage, geoconservation, and geotourism in Africa, assessing the challenges and opportunities in promoting and conserving geoheritage sites, and in providing a forum where outstanding geosites and potential geosites in Africa can be described in a short, useful/practical way for readers of the journal. We are soliciting two types of manuscripts for a VSI on geoheritage in Africa: regular research papers and short reports on existing and potential geosites in Africa. Please click on the hot linked VSI title above to see the range of topics and specific requirements for these two types of submissions.

Special Issue on Advances in forest hydrology in the light of land use change and disturbances
Forests are recognized as prime regulators of the components of the hydrological cycle: they cover over four billion hectares, more than one third of the world’s land surface, and return more than 60000 km3 of water to the atmosphere through transpiration each year. Canopy architecture influences atmospheric turbulence and albedo and thus controls the energy budget and, as a result, transpiration and evaporation processes. Forests provide many hydrological benefits and ecosystem services, including favoring rapid infiltration, increasing soil moisture storage capacity, reducing rates of surface erosion and sediment transport, and moderating the effect of precipitation on hydrological responses and flood generation. Forests modify microclimates stabilizing the temperature of soils and surface waters. Tree roots influence the redistribution of water within the soil profile and add to slope stability in steep terrain. Forests exhibit unique biogeochemical processes, affecting element cycling and the export of carbon and nutrients from forested watersheds. Linking hydrological sciences and forest ecology is therefore the foundation for sustainable and integrated watershed management in forest-dominated ecosystems, even more so in the light of rapid global change. Interactions between forests and their water and energy budget are vital for the distribution of water resources, with important implications for planning and management efforts.
Forest loss is occurring globally, particularly in the tropics. Northern latitudes and large areas of South and East Asia are experiencing increased greening due to afforestation and woody encroachment. Disturbance events, including catastrophic fires and drought mortality are impacting forests in places once thought to be secure from such change. These forest cover dynamics are superimposed on a changing climate, which is also likely to exhibit more frequent weather extremes. The impacts of intersecting land cover and weather variability on the water budget, hydrological regime and ecosystem services remain poorly understood.
This proposed Virtual Special Issue ‘Advances in forest hydrology in the light of land use change and disturbances’ aims at synthesizing the current state of knowledge about physical and biogeochemical processes linking forests to water and the response of these systems to disturbance and change.
The proposed Virtual Special Issue solicits contributions showing latest advances related to the broad theme of forest hydrology, aiming at collecting under its umbrella new experiences that address the urgent need to acquire a deeper knowledge on the role of forest in the water cycle under rapidly changing conditions. The Special Issue encourages the submission of manuscripts particularly focused on process-oriented studies and on better understanding mechanisms and feedbacks between land use change and disturbances on one hand and the hydrological cycle on the other hand, also including ecohydrological aspects and ecosystem services of forests. The Special Issues encourages contributions related, but not limited to, the following research topics:
Role of forests in regulating water fluxes at the catchment scale: ecohydrological functioning of forested catchments in various climates;
Experimental forested catchments: long-term monitoring programs and their value as change detection tools;
Scaling up results obtained for the individual soil-plant-atmosphere continuum to the forest stand or catchment scale;
Changes in hydrological regimes and provision of services related to forest expansion or reforestation;
Forests and water quality: export of solutes from forested catchments;
Role of forests in preventing soil erosion and sediment export at the hillslope or catchment scale;
Quantification of evapotranspiration fluxes at the local or regional scale using isotopic and/or modelling approaches;
Rainfall partitioning: analysis of canopy interception and spatio-temporal distribution of throughfall and relevance for the water cycle;
Impact of increasing frequency of disturbance events (e.g., fire), weather extremes and changing climate on the forest water cycle;
Role of riparian zones in forested environments for controlling water quantity and quality.
