Basin Characterization Model - Simulating Effects of Iowa Soil Management on Water Availability

As a result of climate change, heavy rainfall, as well as extended dry periods, are becoming more common in the Midwestern United States. These trends are only expected to continue. So, increasing the capacity of soil to store water has become more critical. Storing water increases availability in dry conditions. And the absorption of additional water in wet conditions reduces potential...

A random-walk algorithm for modeling lithospheric density and the role of body forces in the evolution of the Midcontinent Rift
