Depressions, or dolines, are fairly common, although cenotes open to the watertable are exceedingly rare in most of the study area. Likewise, failure and success may not always be predicted by distance from the coast or depth of the watertable. These changes he interpreted as a response to variations in watertable levels. The watertable in the experimental site ranged from 1.2 to 1.4 m throughout the crop growth periods. Because the watertable was below 2.0 m depth, the soil was medium textured, and the area was flat, capillary rise was ignored. Nodulation occurred on tabular buttresses in horizontal lines just above the watertable level. The nodules below the watertable showed a similar distribution of colour. These gradual rises in the number of plant species reflect improved peat-forming conditions resulting from local rises of the watertable. This is particularly suggested by the succession of evaporite couplets, which are attributed to pulsating episodes of watertable change. The watertable had an average depth of 25 cm along the sampled radial segment and was visible in the depressions. Both environmental changes could result in watertable changes fatal for survival of some plant species. It is produced in the dry season, in areas with a high watertable or with irrigation, and in the rainy season. In either case the toxic or radioactive waste is trapped in the solid, preventing it from leaching into the local watertable. According to the relative abundance of legume species, possibilities for comparisons between plots, and watertable, representative species and individuals were chosen for nodulation studies. Blocks with water extraction more than recharge indicate receding watertable zones. The formation of inertinite-rich coals is generally related to peat oxidation due to watertable drop or fluctuation. Many hand-dug wells went dry or became contaminated because of the sudden drop in the watertable. This scramble, however, contributed to the further depletion of the already low watertable. The knowledge of the local community about rainfall, watertable elevation, its spatial variability and hydrochemistry was compared with data from a hydrological monitoring program. As an example, thin impure coal seams can form in places other than where a permanent watertable allows peat accumulation, even in semi-arid conditions. These salts cannot be flushed because of the high watertable, hence the accumulation of saline lands in large-scale irrigation systems. It is impossible to measure directly the acreage of land successfully drained and the incremental progression of the gradual lowering of the watertable. Leaching through the subsurface drainage system decreased soil salinity and lowered the watertable. Where conditions allow, it will be grown often in areas with a high watertable to allow production in the dry season. Often, therefore, crops are grown in areas with a high watertable at this time. On the other hand, no attempts were made (at the policy level) to strengthen the natural resource base in terms of replenishing the watertable. An optimal tax will differ by location on the aquifer and will change over time as the watertable and demands change. This would be expected where a subaerial pipe met the watertable. The alternating dark and light gypsum couplets are attributed to pulsating episodes of the watertable. Leakage between the nozzle and watertable was prevented by the use of grease and weights. In wetland habitats, the amplitude of daily fluctuating temperatures becomes large in spring, due to an increasing irradiance and a lowering of the watertable. These soils generally have a shallow saline watertable and often remain waterlogged or submerged for quite a long time. The watertable in the dry season was also deeper than in the wet season, resulting in higher percolation losses. The elevation of the top of the ledge should therefore reflect the height of the watertable. A large proportion of the households draw water from the shallow watertable. A capacitance proximity gauze was mounted on a movable gantry spanning the width of the watertable. The watertable is controlled in the fields by equidistant drains (tertiary canals), which empty into peripheral canals (secondary canals) on which barges navigate. It is more likely to have been formed by tectonic and solutional activity along a vertical joint entirely below the watertable. Optimizing water management and nitrogen fertilization under shallow watertable conditions. This watertable would have settled various sedimentary deposits. When the watertable was above the soil surface, the depth was measured directly. Below the watertable soil is almost completely saturated and gasses travel relatively slowly by diffusion through the water. A high watertable in grassland sites eliminates the possibility of burrowing deep to escape hostile surface conditions. To avoid increased accession to the watertable, guidelines are in place, setting maximum water use levels depending on irrigation and drainage infrastructure. Herbaceous vegetation with hygro-halophyllous plant species dominate in lower areas, under fluvial and watertable influences, while halophyllous succulent scrublands are associated with elevated areas occasionally subject to flooding. At the moment, rainwater seeps away naturally down to the watertable. Many ecological factors are associated with altitude, including light availability in the understorey, soil texture, leaf-litter t hickness, depth to watertable, and frequency of inundation. The watertable was of great importance. By the mid1970s, a falling watertable and declining soil fertility in the longestcultivated village gardens were requiring growers to spend more on fertilisers and motorised pumps. The impact of the declining watertable and the drying up of open wells is reflected in the changes in the composition of wells over the period. Tectonics and basin inversion resulted in the collapse of coal measure forests only locally, that is, where they resulted in watertable drop and improved drainage. These effluents also pose a threat to inland and coastal fisheries and seepage into the watertable means an entry of toxic chemicals into the soil and food chain. The most important reason, according to the farmers, for the increase in bore wells is the declining watertable and the drying up of open wells (table 7). One could have a part of a watershed where the watertable was very near the surface. From the Hansard archive Example from the Hansard archive.
