Els alumnes del batxillerat cient\u00edfic de l’institut Deulofeu han vingut a Emp\u00faries a descobrir la hist\u00f2ria d’uns comtes, d’un castell i d’una duna. I ens hem preguntat: “\u00c9s greu, doctor?” Doncs s\u00ed, el desviament del riu Ter a finals del S XIII, per culpa de les baralles entre el Comte d’Emp\u00faries i el rei Jaume II, va tenir conseq\u00fc\u00e8ncies que arriben als nostres dies.<\/p>\n

Nosaltres hem volgut descobrir la hist\u00f2ria i comprendre la din\u00e0mica actual del Rec del Mol\u00ed. La seva desembocadura funciona com un delta o com un estuari? Ho descobrim analitzant alguns par\u00e0metres f\u00edsico-qu\u00edmics a la mateixa gola del rec.<\/p>\n

Vegeu com els alumnes estudien la densitat de l’aigua, la seva transpar\u00e8ncia i altres propietats relacionades amb la salinitat per establir on es troba avui l’aiguabarreig del rec amb el mar.<\/p>\n

Per altra banda, aprofitem el lloc on estem per a estudiar les restes d’organismes que les onades ens deixen a la platja i esbrinem qui \u00e9s el culpable del forat de les petxines de collaret.<\/p>\n

 <\/p>\n

Al Pedrigolet comptem onades i ens tornem a pregunta “\u00c9s greu, doctor?”<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Finalment al Portitxol calculem la velocitat amb qu\u00e8 actua l’erosi\u00f3 sobre aquest bell arc litoral i acabem concloent que “S\u00ed, \u00e9s molt greu, doctor!”\u00a0\"\"<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
