Tunnel construction is expensive when compared to the construction of other
engineering structures. Detailed surveys indicate that the cost of a tunnel support
system ranges between 30 and 50 percent of the total project cost, and can sometimes
reach upwards of 70 percent. Currently, theoretical studies and experiences
obtained from large projects indicate that costs can be reduced by increasing the
efficiency of rock load estimation and support design. In other words, the selection
of a support system or systems suitable for rock mass conditions encountered during
construction processes plays an important role in reducing project costs. Methods
based on rock-support interaction introduce rational solutions for economical and
safe tunneling because they provide a good combination of design and construction
processes.

Watershed Water Environment And Hydrology Under The Influence Of Anthropogenic And Natural Processes
The major aims of this book, “Watershed Water Environment and Hydrology under the Influence of Anthropogenic and Natural Processes”, are to focus on innovative/new ideas on the watershed water environment from different perspectives across the field; distinguish the evolution of watershed water ecological and environmental quality; clarify the biogeochemical cycling of elements or pollutants; identify and quantify the sources of pollutants; and assess the ecological risk and human health risk of pollutants in the water environment at different watershed scales. In particular, eight peer-reviewed articles were collected, mainly reporting the hydrochemistry-based watershed weathering processes and their environmental implications, trace elements and their risks, and the nutrients cycle in river–reservoir systems. Overall, these papers contribute to several aspects of the watershed water environment and are valuable for river water resource protection and management.

Impacts of Anthropogenic Activities on Watersheds in a Changing Climate
The immediate goal of this Special Issue was the characterization of land uses and occupations (LULC) in watersheds and the assessment of impacts caused by anthropogenic activities. The goal was immediate because the ultimate purpose was to help bring disturbed watersheds to a better condition or a utopian sustainable status. The steps followed to attain this objective included publishing studies on the understanding of factors and variables that control hydrology and water quality changes in response to human activities. Following this first step, the Special Issue selected work that described adaption measures capable of improving the watershed condition (water availability and quality), namely LULC conversions (e.g., monocultures into agro-forestry systems). Concerning the LULC measures, however, efficacy was questioned unless supported by public programs that force consumers to participate in concomitant costs, because conversions may be viewed as an environmental service.

Elimination of Infectious Diseases from the South-East Asia Region
This book discusses the historical context, country experience, and best practices that led to eliminating infectious diseases from the WHO’s South-East Asia Region, such as malaria, lymphatic filariasis, yaws, trachoma, and mother-to-child HIV in the mid-twentieth and twenty-first century. The UN Sustainable Development Goals (3.3) targets to end AIDS, tuberculosis, malaria, and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases by 2030. In this context, this book is of high significance to countries from the SEA region and around the globe. It helps create national strategies and action plans on infectious disease elimination and thus attaining SDG 3.3. This is an open access book.

Lagoon Environments Around the World A Scientific Perspective
Lagoon Environments Around the World - A Scientific Perspective covers a wide range of topics. Typically bordering between land and sea, lagoons are among the most diversely utilized waterways on the planet. Lagoons are extremely important environments socio-economically, and their usage places ever increasing stress on these very sensitive aquatic regions
