Modelo hidrodinámico en el Sistema Lagunar Navachiste, Guasave, Sinaloa, México

Abstract

Abstract.-The Navachiste Lagoon System is connected to the Gulf of California (GC) via 3 tidal channels. The system has an area of approximately 301 km 2 , with an average depth of 2.5 m and an average tide height of 1.5 m. In order to simulate tidal currents and the effect of wind, a numerical hydrodynamic model was applied, integrated in the vertical and in finite differences; to calibrate the model, lagrangean measurements were made and compared with simulated currents in the tidal channels of the system. The model simulates the hydrodynamic behavior of the lagoon system and has a correlation higher than 85% with the trajectories traced by the drift bodies and with the maximum Eulerian velocities measured in the internal channels and in the mouths of the system. Resumen.-El Sistema Lagunar Navachiste se encuentra conectado con el Golfo de California (GC) a través de 3 canales de marea. El sistema cuenta con un área de 301 km 2 aproximadamente, con una profundidad promedio de 2,5 m y una altura de mareas promedio de 1,5 m. Para simular las corrientes de mareas y el efecto del viento se aplicó un modelo hidrodinámico numérico barótropico, integrado en la vertical y en diferencias finitas; para calibrar el modelo se hicieron mediciones lagrangeanas y se compararon con las corrientes simuladas en los canales de marea del sistema. El modelo simula el comportamiento hidrodinámico del sistema lagunar y presenta una correlación superior al 85% con las trayectorias trazadas por los cuerpos de deriva y con las velocidades máximas eulerianas medidas en los canales internos y en las bocas del sistema.Palabras clave: Corrientes de marea, lagunas costeras, simulación de corrientes, modelo hidrodinámico numérico, Sistema Lagunar San Ignacio -Navachiste -Macapule

Health risk of consuming Sphoeroides spp. from the Navachiste Lagoon complex due to its trace metals and organochlorine pesticides content

“…Eighty-six fillet of the pufferfish Sphoeroides spp. were obtained from the local fishers with a fishery permit in the NAV, located in the southern part of the Gulf of California in Mexico between 25.4° and 25.7° N and 108.85°–108.55° W 28 , 29 . None of the specimens were taken alive to perform the following laboratory experiments that were performed in accordance to national or international agreements guidelines and regulations.…”

Nematode parasites in the striped mullet (Mugil cephalus Linnaeus, 1758) in the southern Gulf of California

“…The Gulf of California is the most studied body of water in all of Mexico, considered a national heritage due to its hydrological, geological, biological and fishing characteristics (Ayala-Bocos et al, 2016;Padilla-Serrato et al, 2017). Coastal lagoons are an important component of the gulf in question since they are considered natural ecosystems with high productivity; which is due to the different activities of the primary and secondary producers; in addition to this, their hydrological and ecological characteristics make them areas with rich habitats and a high rate of biodiversity (Sánchez-Lindoro et al, 2017). There are characterized by having a passive transport of suspended sediments, organic and inorganic nutrients, a condition that has _______________ Corresponding editor: Alejandra Volpedo propitiated the ideal environment for various species of fish, crustaceans, mollusks and bivalves of great commercial interest (Herrera-Valdivia, 2016).…”
