The sequence and timing of large late Pleistocene floods from glacial Lake Missoula
Glacial Lake Missoula formed when the Purcell Trench lobe of the Cordilleran ice sheet dammed Clark Fork River in Montana during the Fraser Glaciation (marine oxygen isotope stage 2). Over a period of several thousand years, the lake repeatedly filled and drained through its ice dam, and floodwaters coursed across the landscape in eastern Washington. In this paper, we describe the stratigraphy ...
متن کاملMagnitudes and implications of peak discharges from glacial Lake Missoula
New field evidence and discharge calculation procedures provide new estimates of maximum late Pleistocene glacial Lake Missoula flood discharges for two important reaches along the flood route. Within the Spokane Valley, near the point of release, the peak discharge probably exceeded 17 ± 3 million m-sec. Downstream at Wallula Gap, a major point of flow convergence, peak discharge was about 10 ...
متن کاملFloods and Drowning Incidents by Floods
Floods as natural disasters can cause severe even fatal damages to many communities such as loss of lives and properties every year. The aim of this study is to present the risks of floods for the human life and the basic characteristics of the citizens who lose their lives as a result of floods. For this study, online archives related to flood events have been examined via search engines, “www...
متن کاملMapping hazards from glacier lake outburst floods based on modelling of process cascades at Lake 513, Carhuaz, Peru
Recent warming has had enormous impacts on glaciers and high-mountain environments. Hazards have changed or new ones have emerged, including those from glacier lakes that form as glaciers retreat. The Andes of Peru have repeatedly been severely impacted by glacier lake outburst floods in the past. An important recent event occurred in the Cordillera Blanca in 2010 when an ice avalanche impacted...
متن کاملThe Importance of Lake Overflow Floods for Early Martian Landscape Evolution: Insights from Licus Vallis
Introduction: Open-basin lake outlet valleys are incised when water breaches the basin-confining topography and overflows. Outlet valleys record this flooding event and provide insight into how the lake and surrounding terrain evolved over time [1–5]. Here we present a study of the paleolake outlet Licus Vallis, a >350 km long, >2 km wide, >100 m deep valley that heads at the outlet breach of a...
