Thesis (Ph.D.)--Duke University, 2010.

Coastal adaptation to sea level rise and increased storm risk has garnered tremendous interest from scientists and policy makers alike. Over half the world's population lives and works in the coastal zone and is affected by coastal processes. Shoreline stabilization via beach replenishment---the process of periodically re-building an eroding beach---is now being implemented in many parts of the world to protect coastal property and infrastructure.

520 $a Coastal adaptation to sea level rise and increased storm risk has garnered tremendous interest from scientists and policy makers alike. Over half the world's population lives and works in the coastal zone and is affected by coastal processes. Shoreline stabilization via beach replenishment---the process of periodically re-building an eroding beach---is now being implemented in many parts of the world to protect coastal property and infrastructure.
520 $a Wide beaches produce value---storm protection and recreational amenities---that is, at least partly, capitalized into coastal property values. These beach values ultimately influence the benefit-cost analysis in support of shoreline stabilization policies, which in turn, influences the size and quality of the beach. In this dissertation we are concerned with understanding the feedbacks between physical processes and economic decisions in the coastal zone and the implications of these interconnected dynamic systems for coastal policy. We use non-market valuation methods, optimal control theory, and numerical modeling of coastal processes to demonstrate that dynamic feedbacks between coastal processes and policy intervention to stabilize shorelines significantly affect optimal beach re-nourishment strategies.
520 $a Consistent estimates of beach value are necessary to determine optimal shoreline management strategies. We combine real estate data on residential property with physical beach quality attributes for ten beach towns in North Carolina and estimate the value of beach width, incorporating the endogeneity of beach width when nourishment is the dominant policy. We find that ignoring this endogeneity underestimates the value of beach width; coastal properties are significantly more sensitive to changes in beach width than previously thought. In a dynamic model for optimal beach nourishment we find that optimal nourishment intervals using estimates of the value of beach width accounting for the dynamic beach and endogeneity are closer to the observed nourishment frequency in the locations where shoreline stabilization measures have been undertaken.
520 $a Beyond the implications for a single beach, we develop a two-community game theoretic model with spatial interaction between two neighboring communities. We find that there are welfare gains from coordinated management of the two beaches but there is a trade-off between higher long-run net benefits and increased inequality in the distribution of these benefits in the short term. Further, coordinated management enables both communities to better adapt to increasing rates of sea level rise.
520 $a Finally, we take a first step towards developing a spatial-dynamic model of optimal beach nourishment with a continuum of communities along a coastline making nourishment decisions. In a simple model with a straight initial shoreline and communities facing identical economic and physical characteristics, we find that it is optimal to maintain a flat shoreline. Our work strongly motivates further research in this direction for more realistic shoreline orientations.
