Abstract Photovoltaic (PV) power generation plays an important role in the clean energy. Placing PV on water has therefore become interesting alternative siting solution. In this paper, floating photovoltaic system is divided into four categories: fixed pile system, platform and tracking principles, technologies future challenges of systems will be reviewed. Other encountered with are discussed...

Global constraints on fresh water supplies and the need to dispose of agricultural, municipal, and industrial waste waters have intensified interest in water reuse options. In many instances, the value of the water is decreased solely because of its higher salt concentration. Although quantitative information on crop salt tolerance exists for over 130 crop species, there are many vegetables whi...

Tensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand, especially during the dry season. The arguments a...

Since October 1, 1950, hydrologic-station records in USGS reports have been listed in order of downstream direction along the main stream. All stations on a tributary entering upstream from a mainstream station are listed before that station. A station on a tributary entering between two mainstream stations is listed between those stations. A similar order is followed in listing stations on fir...
