Although there has been extensive research on the geomorphic and ecologic role of
large woody debris (LWD) in streams, the dynamics of LWD in streams are poorly
known due to various measurement difficulties during floods. In this thesis I present the

Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate...
The Endangered Species Act is hailed as the “gold standard” of species conservation legislation both in the U.S. and globally. There are scarce conservation funds that we as a society can spend on the recovery of endangered species, so it is important to understand how the parties involved with this...

ABSTRACT
Understanding the effects of disturbance and restoration on
Studies that have examined watershed groups have lacked the analysis of an empirical national data set to account for the factors that affect watershed groups growth and variation. This has made it difficult to assume any particular relationship between the presence of watershed groups and any environmental, social or political...
This dissertation consists of three essays on private landowners' response to incentives for carbon sequestration in forests.
