Lake basins contain depositional systems whose stratigraphy and sedimentology are highly influenced by allogenic and authigenic processes. Identifying the relative roles of these controls is complicated in settings where both tectonic and climate influences control sediment inpu…

Forest advance into tundra has several ecosystem repercussions. Treeline advance and increased forest density have been observed across the Arctic. Here I document spruce treeline advance as forest advance at 23 sites across Alaska’s Brooks Range. I do this by interpreting histo…

This dissertation consists of six distinct research studies that are broadly classified into two parts. The first part is concerned with the application of emerging data analysis tools rooted in causal inference, nonlinear chaotic dynamical systems, and information theory to det…

In recent years, irrigation projects worldwide, and in the Andean region of Bolivia in particular, have besides solving water problems also generated water conflicts. Historically, most irrigation systems in Bolivia have been set up by peasant communities, and only more recently…

Knowledge of denudation rates over geologic timescales provides important insight into the processes that govern soil formation, the regulation of Earth’s climate, and the evolution of landscapes. Accurately establishing long-term denudation rates is also key to understanding ho…

The Giant Foresets Formation in the Taranaki Basin defines the present-day continental margin of the west coast of New Zealand’s North Island. Using regional 2D and 3D seismic datasets calibrated with exploration wells, this thesis presents a new highresolution seismic stratigra…

The collision of cosmic projectiles with a terrestrial planet’s surface forms topographic depressions, known as impact craters. Since planetary surfaces are continuously bombarded, these features can be observed on nearly all solid bodies in the Solar System. On airless bodies w…

Reynolds Creek, a 239 km2 watershed, was used to study the interplay between constructive and erosive processes in a volcanic landscape. The study was conducted using LiDAR-based geomorphic mapping, field observations, geochronology, and topographic modelling. A lacustrine depos…

Nil Havzası’nın aşağı kıyıdaş ülkesi konumunda bulunan Mısır, havzadaki diğer ülkelerle karşılaştırıldığında, tarihsel süreçte Nil Nehri sularından en fazla yararlanan ülke olmuştur. Bu özellik, yeryüzündeki diğer nehir havzalarıyla karşılaştırıldığında istisnai durumlardan biri…

The Nanaimo Group of southwestern British Columbia has been the source of significant scientific interest due to its relationship with the Baja British Columbia (Baja BC) hypothesis -- the idea that the Nanaimo Group, along with much of western British Columbia, was originally l…
