| Question | Answer |
|---|---|
| Slope Stability | mineral composition;consolidation;zones of weakness; permeability; slope steepness; height; climate; vegetation; time |
| Common Soil Hazard Perceptions | few people aware of these. best solution to avoid building in areas of hazards. obtain insurance if in area of hazard. |
| Downstream Flood | Cover large area, multiple watersheds, produced of large storms (runoff). charictorized by large rise and fall of discharge at particular location. |
| watershed | drainage basin. a topographically bounded area in which runoff is collected and drained by a single stream |
| relative sea level | location of sea at shoreline. affected by: earthquakes, glacier melt, rates of desposition erosion subsidence, tides caused by moon, weather. |
| Karst Topography | associated with subsidence in areas of soulable bedrock. rocks dissolved, evaporates, carbonates. common in humid climates |
| runoff | surface drainage, occurs when amount of water at ground surface exceeds capacity of surface material. eventually flows into streams or rivers |
| Subsidence | ground failure charictorized by sinking or vertical deformation of land. associated with karst topography, thawwing of frozen ground, compaction of sediment, earthquakes, drainage of magma |
| Coastal Erosion Factors | wave volume, storms, climate, sea height, tectonics, weather, human activity, running water, landslides, storm surges |
| minimize landslide hazard | move of important buildings, landslides may be stopped with drains, personal: evaluation of property, avoid vally mouth, monitor small slides, look for weak signs. |
