Case study: Design Parameter Analysis for a Hydraulic Modeling of a Floodplain Protection of La Estrella River, Limón, Costa Rica

摘要: espanolEn la cuenca del rio La Estrella deforestacion en las partes altas y bajas rio, han debilitado capacidad de retencion material cuenca, aumentando frecuencia destructiva descargas extremas. Adicionalmente, el terremoto Limon ano 1991, provoco una alteracion geologica especialmente Valle Estrella, modificando dinamica tradicional estabilidad su cauce. Especificamente, sector objeto este estudio presenta dos agravantes: un asentamiento unica via acceso terrestre muy cerca cauce, lo que significa mayor riesgo para poblado consecuencia es necesario realizar obras proteccion. Para esto, se comparado los resultados modelos hidraulicos 1D 2D con fin evidenciar importancia informacion analisis toma decisiones referente al diseno EnglishIn the basin of River, deforestation in upper and lower parts river has weakened capacity for retention basin, increasing frequency destructive extreme discharges. Additionally, earthquake 1991 caused geological disturbance, especially Valley, modifying traditional dynamics stability its channel. Specifically, one section which is object this study shows two aggravating circumstances: a human settlement location only access road to that very near channel, implying higher risk need implement protection works. We have therefore compared results hydraulic models demonstrate importance information analysis making decisions about design these mitigation works
