Subsidence problems in route design and construction, 1972, Malkin Alexander Bernard, Wood John Charles,
The paper reviews the main causes of ground subsidence as it affects route design and construction in the United Kingdom. Investigation techniques and remedial measures are discussed in relation to both natural and mining subsidence. In addition to the common occurrence of subsidence problems in the coalfields, emphasis is placed on their presence elsewhere in the country. Natural subsidence problems are associated mainly with carbonate and saliferous rocks but mining activity has taken place at various times at numerous geological horizons for a variety of minerals. Future mining activity is likely to involve fewer minerals but will still be dominated by the coal industry. Experience has shown that the conflicting interests of route planners and mineral operators can usually be resolved by negotiation, accompanied in some cases by compensation

Geology and hydrogeology of the El Convento cave-spring system, Southwestern Puerto Rico., 1974, Beck Barry F.
Whereas the North Coast Tertiary Limestones of Puerto Rico are classic karst locales, their southern counterparts are almost devoid of karst development. The El Convento Cave-Spring System is the most prominent feature of the only large scale karst area developed on the South Coast Tertiary limestones. The karst topography is localized on the middle Juana Diaz Formation, which is a reef facies limestone, apparently because of the high density and low permeability of this zone as compared to the surrounding chalks and marls. In the El Convento System a sinking ephemeral stream combines with the flow from two perennial springs inside the cave. The surface drainage has been pirated from the Rio Tallaboa to the east into El Convento's subterranean course. The climate is generally semi-arid with 125-150 cm of rain falling principally as short, intense showers during Sept., Oct., and Nov. Sinking flood waters are absorbed by a small sinkhole and appear two to three hours later in the cave. In the dry season this input is absent. The two springs within the cave have a combined inflow to the system of 1.0 m3/min at low flow but half of this leaks back to the groundwater before it reaches the resurgence. The spring waters are saturated with CaCO3 and high in CO2 (26.4 ppm). As the water flows through the open cave it first becomes supersaturated by losing CO2 and then trends back toward saturation by precipitating CaCO3.

Rapid groundwater flow in fissures in the chalk: an example from south Hampshire, 1974, Atkinson Tc, Smith Di,
Projected road improvements in south Hampshire included plans to dispose of surface drainage into soakaways to be sited near an area of swallow holes in the Chalk. An experiment was undertaken to establish if there was a direct connection between the swallow holes, located near the junction of the Chalk and the Lower Tertiary strata, and major springs used for water supply in the Havant area. As the swallow holes are dry except in periods of storm rainfall a tracer, the fluorescent dye Rhodamine WT, was injected together with a large volume of water into one of the swallow holes. Water samples were collected from the springs at Havant and analysed for Rhodamine WT using a Turner fluorometer. The tracer was found at both sets of springs sampled and the straight line velocity from input point to spring was in excess of 2 km per day. Computations based on the concentration of dye recovered from the springs show that in the event of a tanker spillage within the proposed drainage scheme severe contamination would be expected to occur at the springs. The experiment and the results obtained make it clear that extreme caution should be exercised to avoid contamination of fissure-flow within the Chalk aquifer

Investigations into the watertightness of the proposed Gordon-above-Olga hydro-electric storage South-west Tasmania, 1974, Roberts Glyn T. , Andric Miodrag,
The Gordon-above-Olga scheme is one of several major hydro-electric developments under investigation in the south-west of Tasmania. The proposed storage area includes a zone of Palaeozoic limestone forming part of the eastern limb of a synclinal structure which provided a potential for the existence of leakage paths capable of threatening the viability of the scheme. The geology of the area is described and the methods used in assessing the likelihood of existence of subjacent karst are detailed. The conclusion is drawn on several grounds that neither recent nor ancient activity is likely to have markedly affected the limestone through the synclinorium. In consequence the water-tightness of the proposed reservoir is predicted
