Floods on the Lena River

Floods on the Lena River

In the span of three weeks, spring crept over the Siberian landscape surrounding the northern half of the Lena River. Many of the rivers in Earth’s temperate zones run high in the spring when melting snow and spring rain flood river basins. On the Lena River, however, spring flooding is almost inevitable for another reason: ice. Like other north-flowing rivers, the upper reaches of the Lena melt before their downstream counterparts. Because the northern mouth of the river remains frozen while the southern body of the river flows freely, water naturally builds behind the ice, forming a temporary reservoir that drains as the ice dwindles.

Springtime Comes to the Niagara River

Springtime Comes to the Niagara River

The eastern end of Lake Erie is clogged with ice that is pushed against the shoreline by the prevailing westerly wind. The ice collects in Lake Erie, and the Lake Erie-Niagara River Ice Boom prevents it from flowing down the Niagara River, which is the international boundary between the Canadian Province of Ontario, and New York State. A boom is deployed each December. Operational since 1964, the boom serves several functions: it protects the water intakes for the Niagara River power plants, and it minimizes ice runs (large blocks of ice flowing downstream as ice breaks up in the spring) and blockages that can create damage and flooding along the river.

Ice Jams the Ob River

Ice Jams the Ob River

Russia’s Ob River flows from south to north, and each summer, it thaws in the same direction. The result is that an ice jam sits downstream from thawed portions of the river, which is laden with heavy runoff from melted snow.
