This paper investigates how variation in forest structural characteristics affects the water retention capacity of gaps and forests fir-beech Dinaric Karst. Forests are identified as a key element landscape for provision pristine resources, particularly highly vulnerable karst aquifers characterized by rapid infiltration recharge water, high subsurface permeability, heterogeneous underground fl...

This paper presents the multi-criteria calibration of a regional distributed subsurface water flow model for a 1400 km irrigated agricultural area in the western San Joaquin Valley of California. Two global optimization algorithms were used to identify model parameters using data on spatially distributed local water table depth measurements, district-average groundwater pumping and district-ave...

The nitrates (NO(3)-N) lost through subsurface drainage in the Midwest often exceed concentrations that cause deleterious effects on the receiving streams and lead to hypoxic conditions in the northern Gulf of Mexico. The use of drainage and water quality models along with observed data analysis may provide new insight into the water and nutrient balance in drained agricultural lands and enable...

Impacts into icy bodies often generate near-surface melt chambers and thermal perturbations that soften the ice. We explore post-impact evolution of non-penetrating impacts Europa's ice shell. Simulations viscous deformation show dense impact melts founder before refreezing. If transient cavity depth exceeds half shell thickness, over 40% drains underlying ocean. Drainage from to ocean occurs o...

Macropore flow results in the rapid movement of pesticides to subsurface drains, which may be caused in part by a small portion of macropores directly connected to drains. However, current models fail to account for this direct connection. This research investigated the interrelationship between macropore flow and subsurface drainage on conservative solute and pesticide transport using the Root...
