Custom Soil Resource Report <br /> Water Management <br /> This folder contains a collection of tabular reports that present soil interpretations <br /> related to water management. The reports (tables) include all selected map units <br /> and components for each map unit, limiting features and interpretive ratings. Water <br /> management interpretations are tools for evaluating the potential of the soil in the <br /> application of various water management practices. Example interpretations include <br /> pond reservoir area, embankments, dikes, levees, and excavated ponds. <br /> Ponds and Embankments JZA - Pond) <br /> This table gives information on the soil properties and site features that affect water <br /> management. The degree and kind of soil limitations are given for pond reservoir <br /> areas; embankments, dikes, and levees; and aquifer-fed excavated ponds. The <br /> ratings are both verbal and numerical. Rating class terms indicate the extent to <br /> which the soils are limited by all of the soil features that affect these uses. Not <br /> limited indicates that the soil has features that are very favorable for the specified <br /> use. Good performance and very low maintenance can be expected. Somewhat <br /> limited indicates that the soil has features that are moderately favorable for the <br /> specified use. The limitations can be overcome or minimized by special planning, <br /> design, or installation. Fair performance and moderate maintenance can be <br /> expected. Very limited indicates that the soil has one or more features that are <br /> unfavorable for the specified use. The limitations generally cannot be overcome <br /> without major soil reclamation, special design, or expensive installation procedures. <br /> Poor performance and high maintenance can be expected. <br /> Numerical ratings in the table indicate the severity of individual limitations. The <br /> ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate <br /> gradations between the point at which a soil feature has the greatest negative <br /> impact on the use (1.00) and the point at which the soil feature is not a limitation <br /> (0.00). <br /> Pond reservoir areas hold water behind a dam or embankment. Soils best suited to <br /> this use have low seepage potential in the upper 60 inches. The seepage potential <br /> is determined by the saturated hydraulic conductivity(Ksat) of the soil and the depth <br /> to fractured bedrock or other permeable material. Excessive slope can affect the <br /> storage capacity of the reservoir area. <br /> Embankments, dikes, and levees are raised structures of soil material, generally <br /> less than 20 feet high, constructed to impound water or to protect land against <br /> overflow. Embankments that have zoned construction (core and shell) are not <br /> considered. In this table, the soils are rated as a source of material for embankment <br /> fill. The ratings apply to the soil material below the surface layer to a depth of 5 or 6 <br /> feet. It is assumed that soil layers will be uniformly mixed and compacted during <br /> construction. <br /> The ratings do not indicate the ability of the natural soil to support an embankment. <br /> Soil properties to a depth even greater than the height of the embankment can <br /> affect performance and safety of the embankment. Generally, deeper onsite <br /> investigation is needed to determine these properties. <br /> Soil material in embankments must be resistant to seepage, piping, and erosion and <br /> have favorable compaction characteristics. Unfavorable features include less than 5 <br /> 26 081 <br />
