Potentiometric Surfaces and Groundwater-Level Changes

In the past, groundwater pumped from the Santa Fe Group aquifer system was the principal source of water for the Albuquerque metropolitan area of central New Mexico. The large quantity of groundwater pumping relative to recharge resulted in substantial drawdown in the aquifer system.

Changes in Watershed Hydrologic Response Time with Post-wildfire Changes in Vegetation and Surface Fuels Along a Severely-burned, High-desert Canyon, Bandelier National Monument, NM

Flash flooding can be a destructive and life-threatening response of watersheds to intense rainfall events, particularly in sparsely­ vegetated, or burned watersheds. Studies have been conducted to estimate the magnitude of hydrologic responses of burned watersheds to rainfall events, however the time that it takes a flood to travel through a burned watershed and reach a critical or populated...
