Accurate estimation of saturated hydraulic conductivity (Ks) in soils is essential for various hydrological applications. Ks is difficult to characterize because of its high variability even over short distances, and measurement methods typically require considerable time and re…

While repeated transgressive and regressive sea level cycles have shaped south Florida throughout geological history, modern rates of sea level rise pose a significant risk to the structure and function of the freshwater wetland ecosystems throughout the low-lying Everglades reg…
The Nawalparasi district of Nepal lies in the headwaters of the South Asian Arsenic Crisis region, therefore, offers important insight into the arsenic mobilization process. This research characterizes temporal arsenic variability and other hydrologic parameters at 10 monitoring…
Maryland State Highway Administration (SHA) is in need for evaluation of stiffness and drainage characteristics of graded aggregate base (GAB) stone delivered at highly variable gradations to the construction sites. To fulfill the current need, the mechanical and drainage proper…
An automated method for the simultaneous measurement of water content, soil water pressure, and soil bulk electrical conductivity in soil columns was developed based on time domain reflectometry (TDR), three wire probes and pressure transducers. Soil electrical conductivity was …
Eleven saline-sodic soils in the Indus Plain of Pakistan were studied to characterize their profiles with respect to permeability to water, texture, pH, and soluble ions of Na+, Ca²⁺, Mg²⁺, Co\sb3²⁻, HCO\sb3-, Cl-, and SO\sb4²⁻. Surface and subsurface permeabilities were low, wi…
