Subsurface hydrology of tile‐drained headwater catchments: Compatibility of concepts and hydrochemistry

نویسندگان

چکیده

Concepts and terms used in previous multidisciplinary studies of tile-drained aquitard-dominated catchments (TDADC) are inconsistent confusing. We provide a well-defined, comprehensive conceptual model the subsurface hydrology TDADC by selecting seven mutually compatible consistent concepts. These concepts are: (1) groundwater as main source baseflow headwater streams, (2) dominance ‘pre-event’ water stormflow, (3) importance both macropores matrix, (4) changes flowpaths with rate stream discharge, (5) shallow, lateral flow, (6) interactive nature water, (7) transpiration groundwater. This was successfully ‘field-tested’ examining data collected rural area southern Ontario, Canada. The consist mainly chemical isotopes tracers samples (headwater groundwater, precipitation, tile soil-surface water), supplemented levels meteorological data.

Seasonal Isotope Hydrology of Three Appalachian Forest Catchments

Seasonal oxygen-18 variations in precipitation, throughfall, soil water, spring ̄ow and stream base ̄ow were analysed to compare the hydrology of two forested basins in West Virginia (WV) (34 and 39 ha) and one in Pennsylvania (PA) (1134 ha). Precipitation and throughfall were measured with funnel/bottle samplers, soil water with ceramic-cup suction lysimeters and spring ̄ow/base ̄ows by grab and...

Probabilistic risk analysis in subsurface hydrology

[1] We present a general framework for probabilistic risk assessment (PRA) of subsurface contamination. PRA provides a natural venue for the rigorous quantification of structural (model) and parametric uncertainties inherent in predictions of subsurface flow and transport. A typical PRA starts by identifying relevant components of a subsurface system (e.g., a buried solid-waste tank, an aquitar...
