<br />002851 <br /> <br />Increased Sediment Load <br /> <br />Landslides and debris flows into. streams or rivers add vast quantities of <br />sediment and bedload to the water system. This can 1) silt-up reservoirs, <br />resulting in loss of storage capacity, 2) cause damage to pumps for water <br />intakes, 3) diminish water quality for drinking, 4) kill fish, fish eggs, and <br />destroy fishing areas (resulting in loss of revenue), and 5) cause degradation <br />in crop land when silt decreases permeability. <br /> <br />Road/Railroad Blockage (total) <br /> <br />Total blockage will prevent traffic flow and affect 1) workers' ability to <br />commute, 2) access of emergency vehicles, and 3) the normal flow of commerce. <br /> <br />Bridge Destruction <br /> <br />Bridge destruction has the same effect as total road blockage. <br />pieces of the bridge may eventually cause channel blockage and <br />backwater flooding. <br /> <br />In addition, <br />result in <br /> <br />Damage to Underground and Surface Mining Facilities <br /> <br />Surface dislocation can impact both surface and subsurface mining operation by <br />1) affecting the working surface, 2) blocking entry. ways, and 3) disrupting <br />haulage roads, adits, air shafts, etc. <br /> <br />Utility Damage (sewer, water, power, gas pipelines) <br /> <br />Results of utility damage include 1) loss of life due to explosion of gas <br />lines, 2) loss of service, 3) loss of revenue, and 4) costs of repair. <br /> <br />Ground Surface and Structure Dislocation <br /> <br />Such dislocation can cause 1) utility damage, 2) crop damage, 3) irrigation <br />ditch damage, 4) road blockage, 5) bridge destruction, 6) loss of life, 7) <br />loss of service, 8) loss of revenue, and 9) create potential toxic waste <br />hazard if it involves chemical storage tanks, or fire/explosion hazards in <br />cases of gas or liquid energy fuels. <br /> <br />- 66 - <br />
