Morphodynamics Model of Comaldelta In Coast Of North Central Java

Abstract

North Coastal Region of Central Java many river deltas grow and develop relatively quickly.This study aims to analyze the morphodynamic model of the Delta region on the north coast of Central Java with remote multi-temporal remote sensing techniques in 1972, 1992, 2002 and 2017. This research is descriptive-explanatory, which is trying to find the widest possible data for example to study the dynamics of Delta, and trying to explain the relationship between the factors that influence it. In support of the study, Landsat satellite imagery, Bumi Bumi Indonesia Map, ER Mapper 7.0 software, GIS Arc, GPS, and other field equipment were used. The results showed that the development of Delta Comal tends to be shaped (cuspate) and narrowed. This narrowing is not due to abrasion factor but due to wave and current factors that distribute the sedimentary material of the river to the west side as well as to the east side of the Delta.
