Journal of Water and Land Development - is a peer reviewed research journal published in English. Journal has been published continually since 1998. From 2013, the journal is published quarterly in the spring, summer, autumn, and winter. In 2011 and 2012 the journal was published twice a year, and between 1998 and 2010 it was published as a yearbook. Papers may report the results of experiments, theoretical analyses, design of machines and mechanization systems, processes or processing methods, new materials, new measurements methods or new ideas in information technology.The Journal of Water and Land Development is the quarterly journal devoted to the publication of papers dealing with the following subjects:
- development of water resources in small river basins: assessment of surface and ground water resources, drought and floods, the methods of assessment of man activity influence on water resources;
- sustainable development of agricultural landscape: farm arrangement, wetlands protection, the role of forest and grassland;
- protection of water resources quality: non-point contamination from agriculture, villages and farms, methods of surface and ground water pro-tection;
- irrigation and drainage: management, maintenance and operation, water use, water-crop relations, the influence of drainage and irrigation on environment;
- hydraulic structures for water management in small basins, earth structures, river conservation, etc.
