Infiltration flooding. After a few days of steady rain, when spring snow-melt occurs or during an extreme rainfall event, the soil around [the] home can become saturated with water. Steady snow-melt and precipitation can also raise the ground water level to a point where it is higher than [the] basement floor. This groundwater can infiltrate into basements through cracks in basement walls(or foundation walls) and cracks in basement floors. Infiltration flooding can be a significant problem in older homes where mortar has weakened over the years and cracks have developed in stone or cinder block foundations.  1, record 1, English, - infiltration%20flooding

... a soil/duff drought index [developed by Keetch and Byram (1968]) that ranges from 0 (no drought) to 800 (extreme drought) and is based on soil capacity of 8 inches of water. Factors in the index are maximum daily temperature, daily precipitation, antecedent precipitation, and annual precipitation.  4, record 3, English, - Keetch%2DByram%20drought%20index

The Keetch Byram Drought Index(KBDI) provides a daily measure of soil dryness, which, in turn, gives an indication of water stress in plants. The KBDI represents the net effect of precipitation and evapotranspiration in producing cumulative moisture deficiency in deep duff or upper soil layers. The KBDI has a range from 0(no drought or soil moisture deficiency, i. e. soil at field capacity) to 2000(extreme drought, maximum soil moisture deficiency possible). The index can be viewed as the amount of rain needed to bring the soil back to saturation, with one mm of rain reducing the index by 10 points. The 0-2000 point scale is divided into three drought classes : 0-999=Low; 1000-1499=Moderate; 1500-2000=High. The KBDI is simple to calculate as it uses only two, daily weather observations-maximum temperature and 24-hour rainfall. The system functions in a book-keeping fashion where estimates of daily evapo-transpiration and measurements of precipitation increase or decrease the value of yesterdays index. The KBDI by itself is not a Fire Danger Rating System as it gives no indicate of the ease of ignition of the vegetation, or of the rate of fire spread, fire intensity and difficulty of control. It does however serve as a useful measure of drought occurrence.  7, record 3, English, - Keetch%2DByram%20drought%20index

Keetch-Byram Drought Index (KBDI): ... 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity. Typical of spring dormant season following winter precipitation. 200 - 400: Typical of late spring, early growing season. Lower litter and duff layers are drying and beginning to contribute to fire intensity. 400 - 600: Typical of late summer, early fall. Lower litter and duff layers actively contribute to fire intensity and will burn actively. 600 - 800: Often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.  9, record 3, English, - Keetch%2DByram%20drought%20index

There are bound to be rainstorms whose water the soil cannot fully absorb-a point of major importance in arid and semi-arid areas, for this water can be collected and used to improve productivity locally. The following four water management methods and erosion control structures apply :. runoff harvesting(catching runoff for supplementary irrigation) ;. total absorption or infiltration;. runoff diversion(redirecting excess water) ;. runoff spreading(distribution of runoff energy).... Structures to dissipate runoff energy. When rainfall exceeds the soil' s absorption capacity, the sheet runoff can be controlled by spreading it across the whole slope rather than concentrating it in channels and outlets, where it can cause problems. Its energy can be dispersed by keeping the speed below 25 cm... Such dispersion across the slope is achieved partly by cropping techniques that keep the soil surface rough(clods, many grass stalks, effect of weeds and mulching, etc.) and partly by structures such as permeable microdams, which temporarily slow the flow, allow some sedimentation, spread the flood, reduce peak flows and improve absorption.  1, record 4, English, - runoff%20spreading

watershed : The area of land from which rainfall(and/or snow melt) drains into a single point. Watersheds are also sometimes referred to as drainage basins or drainage areas. Ridges of higher ground generally form the boundaries between watersheds. At these boundaries, rain falling on one side flows toward the low point of one watershed, while rain falling on the other side of the boundary flows toward the low point of a different watershed.  4, record 5, English, - subwatershed
