U.S. Geological Survey
Leake, of Tucson , Arizona , is a research hydrologist
with the U.S. Geological Survey, where he has worked
for more than 30 years. His main areas of work include
water availability, interaction of ground water and
surface water, land subsidence, and development of new
capabilities for simulating processes related to ground-water
flow. For the popular ground-water model program, MODFLOW,
Leake has developed capabilities to simulate land subsidence,
reservoirs, time-varying boundary conditions, and detailed
local models within larger regional models. His current
activities include regional perspectives on ground-water/surface-water
interaction, effects of ground-water withdrawals on
surface water features, geohydrology and water management
in an agricultural area, and further development of
ground-water simulation capabilities applicable in the
