Lula, Bolsonaro seek to disqualify each other ahead of Brazil runoff - Al Jazeera

When rain falls onto the earth, it just doesn't sit there, it starts moving according to the laws of gravity. A portion of the precipitation seeps into the ground to replenish Earth's groundwater. Most of it flows downhill as runoff. Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion. Flowing water has tremendous power—it can move boulders and carve out canyons; check out the Grand Canyon! Runoff of course occurs during storms, and much more water flows in rivers (and as runoff) during storms. For example, in 2001 during a major storm at Peachtree Creek in Atlanta, Georgia, the amount of water that flowed in the river in one day was 7 percent of all the streamflow for the year. Some definitions of runoff:1. That part of the precipitation, snow melt, or irrigation water that appears in uncontrolled (not regulated by a dam upstream) surface streams, rivers, drains or sewers. Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or groundwater runoff.2.

A drone strike on a market in a border region disputed by Sudan and South Sudan killed at least 153 people on Monday, according to a local official, the latest in a wave of deadly attacks. The strike pushed the toll from attacks in recent days to more than 250, underscoring the lethality of airstrikes in Sudan’s war, which ⁠erupted in April 2023 between the Sudanese Armed Forces ⁠and the paramilitary Rapid Support Forces (RSF). Yohanna Akol Ngor, the Abyei administration’s caretaker information minister, blamed Sudan’s military, without providing evidence, for Monday’s attack on Amiet market, north of Abyei town. “We have recorded 153 deaths,” Akol said. Sudan’s military did not respond to a request for comment. A witness said he heard five large explosions that led to a fuel depot nearby catching fire. “People started evacuating the casualties. They ​had injuries from shrapnel on their stomach and legs … In one site, I saw 28 bodies that were burnt,” the witness said, asking not to be named for safety reasons.
