Steady propagation of wetting front within the unsaturated cohesionless dam materials resulted in a decrease in matric suction (negative pore-water pressure) which caused a reduction in interstitial voids, as evidenced by the formation of concave upward depressions at the central part of the dam crest.
In this case, crest settlement is related to the formation of a concave-upward depression at the center of the dam crest, as a result of internal erosion and piping within the material underlying the dam crest.
This consequently led to the formation of concave-upward depressions, mostly at the center of the dam crest.
This was usually followed by the settlement of the entire dam, and subsequent formation of concave-upward depressions at the center of the dam crest.
Concave-upward depressions observed during the initiation of internal erosion and piping were monitored by positioning one of the sensors (H d1) directly above the center of the dam crest, while the other sensor (H d2) was fixed 0.07 m from the central part of the crest.
"I think it took me until I was 23 to really come out of the depression, but the upward process started at 19, as soon as I stopped smoking weed".
The upward recharge induced by the depression cone is verified based on water level records, major ions, 2H, 18O and kinds of statistical analyses.
They were preparing to surf a standing river wave in the St . Lawrence where high-velocity water roars over a steep river-bottom depression, pitches back and upward, and creates a waist-to-overhead breaker.
Significant effect size heterogeneity was observed across sample types, methods of assessing upward counterfactual thinking, and types of depression scale.
The prevalence rates of mental health conditions and in particular, anxiety and depression have shown an upward trend in recent years, probably exacerbated by the current economic situation and high rates of employment in our setting [ 38].
Electrocardiography revealed a regular narrow QRS complex but diffuse PR segment depression and localized concave upward ST segment elevation in leads aVL and V1 V3 with reciprocal changes in the inferior leads.
