Abstract
Sea level rise due to climate change affects beaches, which are a source of high recreational value in the economy. The tourism carrying capacity (TCC) assessment is one of the tools to determine the management capacity of a beach. Pattaya beach represents the character of well-known beaches in Thailand, while Chalatat beach represents the character of beaches that are the focus of domestic tourism. To evaluate beach area this study detected the shoreline position using Google Earth images with tidal correction. The Bruun rule was used for shoreline projection. TCC was calculated by using the beach area, correction factors, and management capacity. The results find that the current effective carrying capacity is approximately 200,000 for Pattaya beach and 49,000 for Chalatat beach. Although the Chalatat beach areas are larger than Pattaya, the effective carrying capacity of Pattaya beach is larger than the effective carrying capacity of Chalatat beach for all situations because TCC is affected by beach areas, correction factors, and management capacity. Because beach areas experience the effects of sea-level rise, protection against future beach loss should be considered for coastal management.
Highlights
The beach is an important ecosystem that has many benefits, including recreation, fisheries, and a buffer near the ocean
Several studies have used the Bruun rule to examine the impacts of sea-level rise on shoreline retreat that affect tourism carrying capacity (TCC), such as at Catalan beaches where physical carrying capacity (PCC) will decrease in proportion to the sea level rise [8]
Data on beach management were collected by field observation of the two beaches. These findings should be considered in the planning of near-future coastal zone management to protect the tourism carrying capacity and beach areas from future sea level rise
Summary
The beach is an important ecosystem that has many benefits, including recreation, fisheries, and a buffer near the ocean. Beach area loss from sea-level rise decreases the carrying capacity of the beach, especially in physical terms. Several studies have used the Bruun rule to examine the impacts of sea-level rise on shoreline retreat that affect TCC, such as at Catalan beaches where PCC will decrease in proportion to the sea level rise [8]. The study of TCC at Jomtien beach examined present-day scenarios, which do not account for the sea level rise from climate change in future scenarios. Data on beach management were collected by field observation of the two beaches These findings should be considered in the planning of near-future coastal zone management to protect the tourism carrying capacity and beach areas from future sea level rise
