Section 785.19 (d) Continued. <br />• an economic analysis. <br />(vii) Such other data as the regulatory authority may require. <br />(3) The surveys required by this paragraph should identify those <br />geologic, hydrologic, and biologic characteristics of the alluvial <br />valley floor. Charcteristics which support the essential hydrologic <br />functions and which must be evaluated in a complete application include, <br />but are not limited to: <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 />• <br />(B) The relief, slope 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 />(ii) Characteristics supporting the function of storing water which <br />include, but are not limited to-- <br />• <br />785-20 <br />
