Alteración hidrológica del barranco de Lerma (Zaragoza) por la transformación en regadío
Bibliographic record
Abstract
El regadio se expande sin un verdadero conocimiento del impacto que genera ni de su evolucion en el tiempo. Este trabajo pretende analizar la alteracion que supone una transformacion en regadio sobre la hidrologia del cauce natural receptor de sus retornos de riego. Para ello, se han cuantificado tendencias e identificado variaciones estacionales del caudal, conductividad electrica y concentracion de nitrato del barranco de Lerma (Zaragoza) desde su condicion de secano (2004) hasta que el nuevo regadio estuvo consolidado (2011). La transformacion en regadio supuso un aumento de caudal (4.2 L/s ano) y concentracion de nitrato (5.6 mg/L ano). La conductividad electrica disminuyo (-0.4 mS/cm ano), aunque la masa de sales exportada tambien se incremento (232 kg/ano) a causa del ascenso de caudal. La gestion del regadio unido a las caracteristicas hidrogeologicas genero ciclos anuales, semanales y diarios en los parametros analizados. Los resultados ponen de manifiesto la alteracion hidrologica y su evolucion en el tiempo por la puesta en regadio que deberia ser tenida en cuenta para la adecuada planificacion de los recursos hidricos.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
