Fall 2017 Central Premise Karst is defined as a selforganizing aquifer Interaction and feedback between soluble matrix and solvent flow In carbonate aquifers the selforganization can occur without biota. Monica . Mustain. From groundwater encyclopedia: “. Refers to lands primarily underlain by limestone and dolomite where surface water is integrally connected to the ground water system from preferential flow routes.”.

A Global Issue…. Huge extent (40% of continental area). Generally low rainfall (seasonal or persistent dryness governs plant-soil relations). Significant human dependence and vulnerability (drought). Weathering . Students will be able to describe and give examples of chemical and physical weathering.. . Weathering. The breakdown of materials on Earth’s crust into smaller pieces.. Two Types of Weathering. Streams in karst areas sometimes lose large volumes of surface water through gradual loss into underground caverns. . Environmental Concerns with Karst. More Concerns. Cow manure in streams can lead directly to underground cavern systems.. Fall 2015. Core Questions. Primary production is controlled by time-varying soil moisture. Stochastic rainfall inputs. Soil physical properties control storage and “overflow”. Moisture-dependent ET loss. Primary production is controlled by time-varying soil moisture. Stochastic rainfall inputs.
