  • Possibilities for water conservation in Bulgaria
  • Bulgaria ; Consumption ; Demand ; Water ; Water economics ; Water management ; Water use
  • Existing water resources can become inadequate if water losses are too important and if there is an irrational use of water. Water conservation could solve some water supply problems by providing more reasonable water consumption and additional time
  • for development of new resources. The possibilities for reducing water use and the need for developing a national conservation program are discussed. An analysis of the variables which affect water use is performed. Developing of water-use efficiency standards
  • for plumbing fixtures and conservation-oriented water rates and measures are proposed.

  • Mineral waters and hydrogeothermal resources in Bulgaria
  • Water resources of Bulgaria
  • Aquifer ; Bulgaria ; Geological structure ; Geothermics ; Mineral water ; Natural resources ; Neotectonics ; Water ; Water resources
  • This paper presents generalized information and evaluation of the geological structure and neotectonic features of Bulgaria and their control on the formation, reproduction and accumulation of thermal mineral waters; the spatial, qualitative
  • and quantitative features of the principal groups of thermal mineral waters and their aquifer systems; and the prospects for utilization of the hydrogeothermal wealth in the social and economic life of this country.

  • The water resources of Bulgaria: an overview
  • Water resources of Bulgaria
  • Bulgaria ; Climatic variability ; Drainage network ; Hydraulic works ; Mountain ; Orographic effect ; Precipitation ; Water ; Water management ; Water resources ; Water use ; Watershed
  • Bulgaria's indigenous water resources derive largely from mountains watersheds where orographic effects enhance precipitation. These watersheds provide resources upon which lowland communities, industry, and irrigation depend. This paper explores
  • the physical and human geography of Bulgarian water resources as aperspective from which the multiple dimensions of current Bulgarian water research and water issues can be seen.

  • Non-conventional water for irrigation during drought in Bulgaria

  • Applied hydrology ; Bulgaria ; Crop ; Drainage ; Drought ; Health ; Irrigation ; Polluted water ; Pollution ; Risk ; Sea water ; Soil ; Water ; Water quality ; Water resources
  • Under the drought conditions that have occurred in Bulgaria during the last decade, agricultural use of non-conventional water may be an important resource. This is a specific case of simultaneous purification and utilisation by soil ecological
  • systems. However, using non-conventional quality water presents a number of ecological and health risks and poses problems connected with soil and surface and groundwater contaminated and with producing crops of acceptable quality. This paper reviews
  • the work of the AA. in assessing the irrigation potentials of waste water in Bulgaria.

  • Comprehensive planning for water resources exploitation and water pollution control for Changli County - a case study for small towns in China
  • China ; Drainage network ; Environment ; Environmental conservation ; Pollution control ; Small town ; Tourism ; Water pollution ; Water resources
  • With rapid development of socio-economy and urbanization, many new small towns have occurred in China, and the concerned ecological problems such as water pollution and soil erosion have been gradually changed into local point source pollution
  • . The Research Center of Water Problems undertook a research project of comprehensive planning of urban environment of Changli County, Hebei Province. The planning is aimed to protect and to improve the environment with the least cost, to promote the suitable

  • Variation in water content and wetting patterns in Dutch water repellent peaty clay and clayey peat soils
  • Clay ; Netherlands (The) ; Peat ; Runoff ; Soil ; Soil moisture ; Soil properties ; Soil water
  • The variation in water content of grass-covered peaty clay and clayey peat soils was studied at 6 sites in the Netherlands. The topsoils were water repellent during dry spells. However, the measurements revealed that preferential flow
  • was not limited to macropore flow: irregular, fingerlike wetting patterns were also formed in the soil matrix. Due to these typical wetting patterns, soil water content varied over short distances at all sites at all sampling dates.

  • This article presents the results of a study carried out in the Puck Bay concerning the alterations of pore water chlorinity, pore water (O 18, D) isotope composition and near-bottom water salinity caused by groundwater seepage. The groundwater
  • seepage decreases the chlorinity of interstitial water and the salinity of near-bottom water. The comparison of the oxygen and hydrogen isotope composition of underground, interstitial and near-bottom waters indicated a reduction of the content of heavy
  • isotopes in the interstitial water and thus gave evidence of freshwater seepage through the sea floor.

  • Nuisance cyanobacterial blooms are an important environmenttal pproblem. The sustainable management of toxic cyanobacteria would increase the conservation and amenity value of affected water bodies, and decrease on-site water treatment costs
  • . Different management strategies are therefore considered within the context of the current state of the UK water industry. Particular reference is made to the potential impact of the 1994 Ofwat-determined water-price increase limits on environmental policy

  • Relief peels in the study of palaeoflood slack-water sediments
  • This paper shows that relief peels are an effective, and in some cases, indispensable aid in the description and interpretation of especially very fine-grained palaeoflood deposited slack-water sediments. Also it shows that the description of slack
  • -water sediments as massive and structureless, is erroneous in most cases where relief peels are studied in conjunction with field-outcrop sections. Relief peels are an important tool in differentiating between palaeoflood, nonpalaeoflood and intraflood
