Section 785.19 (d) Continued. <br />I • <br />(i) Characteristics supporting the function of collecting water which <br />include, but are not limited to-- <br />(A) The amount and rate of runoff and a water balance analysis, with <br />respect to rainfall, evapotranspiration, infiltration and ground water <br />recharge; <br />(B) The relief, elope, and density of the network of drainage channels; <br />(C) The infiltration, permeability, porosity and transmissivity of un- <br />consolidated deposits of the valley floor that either constitute the <br />aquifer associated with the stream or lie between the aquifer and the <br />stream; and <br />(D) Other factors that affect the interchange of water between surface <br />streams and ground water systems, including the depth to ground water, <br />the direction of ground water flow, the extent to which the stream and <br />associated alluvial ground water aquifers provide recharge to, or are <br />recharged by bedrock aquifers. <br />(13) Characteristics supporting the function of storing water which <br />include, but are not limited to-- <br />(A) Surface roughness, slope, and vegetation of the channel, flood <br />plain, and low terraces that retard the flow of surface waters; <br />(B) Porosity, permeability, waterholding capacity, saturated thickness <br />and volume of aquifers associated with streams, including alluvial <br />aquifers, perched aquifers, and other water bearing zones found beneath <br />valley floors; and <br />(C) Moisture held in soils or the plant growth medium within the allu- <br />vial valley floor, and the physical and chemical properties of the <br />. subsoil that provide for sustained vegetation growth or cover during <br />extended periods of low precipitation. <br />785-31 <br />
