Geophysical logging For hydrogeology
Geophysical logging is the measurement and analysis of electrical, acoustic, nuclear, and other physical properties in a borehole using wireline or direct push technology. Geophysical logging is one of the primary methods of collecting subsurface information for hydrogeologic investigations. Groundwater scientists and engineers should have a basic understanding of borehole geophysics and how it is

Getting Started with MODFLFOW
Numerical modeling of groundwater flow systems was once accessible only to modeling specialists in the hydrogeological community. Software such as MODFLOW—the most frequently used groundwater modeling program in the world—and associated graphical user interfaces (GUIs) have made modeling possible for most groundwater scientists. This book provides the bridge from understanding to implementing mode

Bayesian applications in environmental and ecological studies with R and Stan
Modern ecological and environmental sciences are dominated by observational data. As a result, traditional statistical training often leaves scientists ill-prepared for the data analysis tasks they encounter in their work. Bayesian methods provide a more robust and flexible tool for data analysis, as they enable information from different sources to be brought into the modelling process. Bayesian

Electrical imaging for hydrogeology
Geophysical methods offer hydrogeologists unprecedented access to understanding subsurface parameters and processes. In this book, we outline the theory and application of electrical imaging methods, which inject current into the ground and measure the resultant potentials. These data are sensitive to rock type, grain size, porosity, pore fluid electrical conductivity, saturation, and temperature.

Geology & mineralogy of the Old Mine Park area Trumbull Connecticut
Old Mine Park, in the northern Trumbull area (also known as Long Hill) of southwestern Connecticut, is a recreation area encompassing the mineral-rich hill of “Saganawamps” and owned by the Town of Trumbull. Most of its 72 acres are wooded, rocky and undeveloped but it is surrounded by dense infrastructure and transportation, residential, retail, and commercial development (Figure 1). It preserves

Spreading like wildfire: The rising threat of extraordinary landscape fires - A rapid response assessment
Free-burning landscape fire is an important natural phenomenon critical to the healthy functioning of many ecosystems. It is an important land management tool, culturally, economically, and ecologically. Therefore, not all vegetation fires are unwanted. This Rapid Response Assessment (RRA) focuses on the apparent increase in the occurrence, extent, duration, and consequences of wildfires – unusual

Turtles of the World: A guide to every family
Turtles of the World reveals the extraordinary diversity of these amazing reptiles. Characterized by the bony shell that acts as a shield to protect the softer body within, turtles are survivors from the time of the dinosaurs and are even more ancient in evolutionary terms than snakes and crocodilians. Of more than 350 species known today, some are highly endangered. In this beautiful guide, turtl

Visitors count! Guidance for protected areas on the economic analysis of visitation
The value of protected areas is often hidden from direct view. Once managers understand the number and behaviour of visitors they host, and the revenues and costs they generate, informed decisions on management plans and tourism strategies can be made.
Demonstrating the positive impact of protected areas on the local economy
can lead to greater buy-in and ownership of conservation practices and
