Over the past few years, more and more studies have demonstrated that liquid water once existed in abundance on the surface of the Red Planet. The latest studies from the Mars Express spacecraft image a former lakebed in detail, highlighting a fan-shaped river delta as well. In fact, it was the discovery of the fossi... |

A group of investigators from the Netherlands has recently augmented an existing model on soil sedimentation and erosion with data on the subsoil, thus producing one of the most advanced tools for simulating the way rivers and deltas develop over geological times.The team, based at the Delft University of Technology ... |

Investigators have determined that a body of water similar in size to the modern-day Colorado River may have flow backwards, from California to Arizona and Utah. The study reveals that the ancient California River would have appeared to be flowing backwards for modern observers trekking along its shore, or rafting on... |

A group of researchers has recently determined that the Mississippi River delta may in fact be playing a beneficial role in protecting the delicate Louisiana coastlines from the effects of crude oil contamination. With the explosion of the Deepwater Horizon drilling rig, about two months ago, the delicate ecosystems ... |

The debate as to whether or not the Red Planet was covered by a large ocean many years ago has been hotly discussed in the international scientific community for decades. Reaching a conclusion has been difficult to say the least, given that none of the evidence (pro or against) were conclusive. But the discussion may... |

Scientists have determined that the current global-warming phenomenon will not lead to all the river deltas in the world being swamped. A multitude of factors will determine which of the landscape features will be destroyed or not, including the level of tectonic activity in plates around their locations, and the typ... |

In a new, long-term plan that stretches about 100 years into the future, engineers write that diverting the sediment-rich waters from the Mississippi River towards New Orleans could result in important, new stretches of land being created around the city over the next century. The river's delta is already shrink... |

Scientists at the University of Colorado in Boulder (UCB) have recently released a new report on the situation of deltas around the world, which states that their condition is deteriorating globally. Most at risk is the low-lying variety. Human “improvements” and development made around or on them render ... |

Understanding how our planet's climate will modify over the next few decades is currently one of the most researched topics in the world, and for good reason. Figuring out how and where global warming will hit hardest may give us enough time to plan defenses, which would prevent billions of people from dying of ... |
