Estuarine Salinity Response to Freshwater Pulses

نویسندگان

چکیده

Freshwater pulses (during which river discharge is much higher than average) occur in many estuaries and strongly impact estuarine functioning. To gain insight into the salinity response to freshwater pulses, an idealized model presented. With respect earlier models on spatiotemporal behavior of estuaries, it includes additional processes that provide a more detailed vertical structure salinity. Simulation observed pulse Guadalquivir Estuary (Spain) shows this important adequately simulate structure. The used determine dependency for different background discharge, tides, intensities durations pulses. Results indicate change salt intrusion length due proportional ratio between peak depends linearly duration if there no equilibration during pulse. adjustment time, time takes estuary reach equilibrium after increase scales with discharge. recovery is, decrease does not depend amount caused by strength tides minor importance dynamics

Home advantage? Decomposition across the freshwater-estuarine transition zone varies with litter origin and local salinity.

Expected increases in the frequency and intensity of storm surges and river flooding may greatly affect the relative salinity of estuarine environments over the coming decades. In this experiment we used detritus from three contrasting environments (marine Fucus vesiculosus; estuarine Spartina anglica; terrestrial Quercus robur) to test the prediction that the decomposition of the different typ...

Simulating the Response of Estuarine Salinity to Natural and Anthropogenic Controls

The response of salinity in Apalachicola Bay, Florida to changes in water management alternatives and storm and sea level rise is studied using an integrated high-resolution hydrodynamic modeling system based on Curvilinear-grid Hydrodynamics in 3D (CH3D), an oyster population model, and probability analysis. The model uses input from river inflow, ocean and atmospheric forcing and is verified ...
