Abstract
A simple analytical model for flow in the creeks is formulated, built up and applied in the real conditions in Nang Hai creek, Can Gio mangrove Biosphere Reserve (Ho Chi Minh city).Observed data of current speed and water level in the creek in the year of 2005 were used to find the friction coefficients in the mangrove swamp and to apply in the model. Results from calculated modeling show obviously the tidal asymmetry in mangrove creek. The peaks of current speed at flood and ebb tides are not equal as the swamp is inundated. The friction coefficients have the great influence in the tidal asymmetry. The friction coefficient in the creek can change remarkably the current speed in the creek, inducing the changes of the current speed peaks. The friction coefficient in the swamp has much less influenced to the current speed in the creeks.
Highlights
A notable characteristic of the hydrodynamics of mangrove creeks is the asymmetry between the flood and ebb water makes the flow friction dominated, and the momentum balance reduces to a balance between the water surface slope and the friction term [1]
From the simulated model and the characteristic parameters in Nang Hai creek and its swamp, compared with the observed data of current velocities in the creek, we could predict the current flows with the suitable friction coefficients
Results show that the calculated velocity gave the most suitable data compared with the measured velocity when the friction coefficient with the order of 10-4 was chosen
Summary
A notable characteristic of the hydrodynamics of mangrove creeks is the asymmetry between the flood and ebb water makes the flow friction dominated, and the momentum balance reduces to a balance between the water surface slope and the friction term [1]. Velocity [1], [2], [3]. The aim of the study is to MODELLING formulate and to build up a simple analytical model for flow in the creeks. The water level and friction coefficients are considered in the model of swamp-creek system. A simple analytical model for flow in the creeks is formulated. Swamp is characterized by a volume-water height relation and the creek is characterized by its average width, depth and length. The system is separated into two parts: the creek where inertial has to be
