The effect of Mississippi River diversions on oyster production

The Mississippi River diversions are intended to build new land by diverting floodwaters from the river into open water, wetlands there. Since oyster cultivation depends on the oyster beds seeing a narrow salinity range, there is a concern that the diversion…

OHIO RIVER BASIN– Formulating Climate Change Mitigation/Adaptation Strategies through Regional Collaboration with the ORB Alliance

Generally, modeling results indicate a gradual increase in annual mean temperatures between 2011 and 2040 amounting to one-half degree per decade, with greater increases between 2041 and 2099 of one full degree per decade. Hydrologic flow changes show substantial variability…

Mississippi River Flood History

The record of Mississippi River floods goes back to the earliest explorers: High Flows and Flood History on the Lower Mississippi River Below Red River Landing, LA (1543­ – Present) and the paleoclimate records show megafloods greatly exceeding even the 1927 flood: Brown,…

Corps of Engineers systematically underestimates river flood risk

Playing Politics with Morganza?

Took a drive up to the Old River Control Structure and the Morganza Spillway on the 12th of May. I was curious about what is keeping the Corps from opening the spillway until the flow hits 1.5 M CFS. One…

Mississippi River Flood of 2011

At least as to river heights, the Flood of 2011 may be second or third largest Mississippi River Flood in modern times. Total volume of the flood is hard to compare because the river and the tributaries are more constrained than in the past. Water in a leveed river will be much higher than in a river without levees where it can spread out horizontally.

Projected flood heights – NOAA (Morganza floodway projections)[…]

The Control of Nature – Morganza Spillway

John McPhee has written a fascinating history of the River Control Structure at Morganza. While it is not clear that the Mississippi still wants to go down the Atchafalaya, losing the River Control Structure in a flood would still be a…
