<p>A variety of anthropogenic activities are now known to have triggered earthquakes. These include mining, filling of artificial water reservoirs, production of petroleum and geothermal energy, high- pressure fluid injections into shallow crust and many more. Among these, artificial water reservoir triggered seismicity (RTS) is most prominent, with the largest triggered earthquake of M 6.3 having occurred at Koyna, India in 1967. Whether, the devastating Mw 7.8 Sichuan, China earthquake of 8 May 2008 that claimed some 80,000 human lives was triggered by filling of the nearby Zipingpu reservoir, continues to be debated.</p><p>There are over 100 sites globally where RTS events of M ≥ 4 have occurred. Here we present an over view of RTS, common characteristics of the RTS earthquake sequences that help to discriminate them from normal earthquake sequences and also help selection of safer sites for locating dams to create artificial water reservoirs.</p><p>Koyna, near the west coast of India continues to be most prominent site where triggered- earthquakes have been occurring since the impoundment of the reservoir in 1962 and have continued till now with 22 M ≥ 5, ~ 200 M ≥ 4 and several thousands smaller earthquakes. It was argued that Koyna is a very suitable site for near field investigations of triggered earthquakes. Discussions were held in dedicated ICDP workshops and finally a go ahead was given. As a precursor to setting up a near field laboratory at ~ 7 km depth, a 3 km deep Pilot Borehole has been completed in June 2017 and investigations are being carried out for necessary input for setting up the deep borehole laboratory. Salient features of this project are also presented.</p>

Artificial Origin

Opencast fields mining leads to land disturbance when conducting mining operations and storing of overburden rocks. The timely reclaiming of the disturbed lands according to the legislation requirements is an immediate duty of the subsoil user. The reclamation of the previously mined-out space of quarries refers to an extremely important tasks of the mining enterprise. The use of water management direction in reclamation assumes the use of previously mined-out space of a quarry to create the water reservoir through various methods of rehabilitation. There are presented various ways of designing the coastal zone of the created artificial water reservoirs in the previously mined-out space of the quarries located worldwide, which are used for the recreational purposes. The various profiles of slopes of artificial water reservoirs in a quarry with more low gradients, suitable for swimming and recreation are shown. Designing of a coastal area on the site of a quarry, intended for water reservoirs, depends on the water level position in the created body of water. The water reservoir, as the lake of artificial origin, created on the former quarry site, is shown. The purpose of the article is to substantiate the methodological approaches and engineering solutions concerning reclamation of the mined-out space after the opencast mining for the recreational purposes.

Artificial water reservoirs in Kalmykiya, which has limited water resources, were developed for a potable water supply for the local population, cattle breeding, and irrigation. Currently, they are strongly contaminated by biogenic substances. Calculations are provided in this study that confirm the hypothesis that cattle breeding (watering points of cattle and run-off from cattle breeding areas) developed in the water catchment area suppl 12 tons or from 20 to 700 g of phosphorus per 1 m2 of water surface per year in the absence of other contaminants; this is the main reason that phosphorus content in all water reservoirs exceeds the maximum allowable concentration established for fishery water reservoirs (MACf) by tens of thousands of times. The highest proportion (80%) of the overall volume of incoming phosphorus originates from the bovine cattle. Phosphorus loads exceed the allowed and critical values for functioning of the water ecosystem by from 1 to 3 orders of magnitude, forming conditions for eutrophication and rendering water of these reservoirs unsuitable for potable water supply, including for cattle watering points.

AbstractRotifer diversity was studied in three different types of artificial water bodies situated in one of the largest cities in Poland. The bodies of water were as follows: a fountain in a city park, the Nowa Huta dam reservoir, and the Bagry gravelpit. The lowest number of rotifer species (23) was noted in the urban fountain, and the highest (36) in the Bagry gravel-pit lake. Rotifers’ communities in the investigated water reservoirs showed different levels of diversity and density. The most numerous species in the dam reservoir was Trichocerca similis (2511 ind. l
