Brief Report

Result view original soils and climate control the interior movement of water in and thru regolith. This dynamic process, called soil hydrology (also called hydrogeology), are often approached within a framework of conceptual models that combine the influences of regional climate (with local variations), stratigraphy (pedo- and geo-stratigraphic circumstances) and topography (macro- and micro-topography). When combined, these elements can provide a practical understanding and prediction of how and where water within the vadose zone will typically move within a landscape. These conceptual models also can be extended to larger land areas, with adjustments made because the elements, like stratigraphy, vary. In situations where highly detailed monitoring isn't cost-effective; soil hydrology provides a way of incorporating what's known about water flow into our understanding, presentation and use of the soils cape. Soil hydrology can, in turn, be wont to explain soil features (soil morphology), distributions (soil geography) and ecosystem functions (dynamics). It also can be wont to guide land management decisions by providing a basis for partitioning the landscape into subsets with different input tolerances. Water functions both as a catalyst for pedogenic processes within soil and as a vehicle for the transport and redistribution of materials and energy within and between soils.

 Soil hydrology, the study of water movement within soils and thru landscapes, represents a nexus that bridges the various disciplines of pedology, hydrology, and geology and ecosystems analysis. Soil hydrology can substantially explain soil morphology, soil geography and ecosystem function (e.g., fluxes of soluble constituents: distributions and direction of movement). Soil hydrology also can serve as a tool for choosing optimal land use decisions for specific applications and tailored to different parts of landscapes, like vadose zone issues regarding contaminant movement above and to the groundwater table. Lastly, soil hydrology commonly involves more than just the uppermost 2 m emphasized in soil taxonomy and soil inventory. Vadose zone water movement is affected not only by the supply of water (inputs minus the outputs), but also by the thickness of porous media available to carry and internally transport water. Unless an aquiclude or permanent groundwater table occurs near the land surface, the vadose zone will commonly exceed the uppermost 2 m. Consequently, such deep regolith must be encompassed in models and analyses if it affects vadose zone dynamics considerable advances are made in recent years in extending the hydrologic cycle to an understanding and articulation of soil hydrology.

  This has evolved in two related but different contexts: (a) Theoretical MathML:/mathematical modelling approach generally focused on laboratory or limited point data and (b) in place (field) measurement and landscape assessment. Both contexts recognize the necessity to know both the precise details of how and why water moves in porous media, also as the way to project these processes to large land areas. The stress here is upon the second context of determining and exploiting field and landscape-scaled conceptual models and subsequent inferences of water movement through landscapes.
