China's water ressources and its utilization in Water in China and elsewhere.

An appraisal of water resources of India and need for national water policy in Natural Resources.

Water supply problems of Riyadh, Saudi Arabia in Water in the urban environment.

Study of water surface exploration at Yucheng integrated experimental station, Shandong, China
The relationships between evaporation form water surfaces and factors such as meteorological parameters, surface area and depth of water bodies, structure of evaporation pans and its installation have been analyzed. The daily, yearly and interannual
variations of evaporation from water surfaces are also discussed.

Water quality of lake Toya and of all the lake's in-and outflow rivers
The A. investigated the water quality (PH, temperature, conductivity and concentration of each metal ion) in order to assess the long-term influence of the eruption of Mt Usu and the changes on the standing water quality of Lake Toya. They concluded
that the general features of the lake water were considered not to have changed. - (SGA)

By combination of century-old experiences with open dug wells and surface reservoirs with scientific techniques of ground water prospecting and supply of energy, evolutionarily an alternative water management system can be developed
. This will consist of surface reservoirs for ground water recharge, natural fractures and dykes for water transport, modern exploration techniques for their identification and traditional open dug wells as water sources. (L'A.).

Manâbe'va masâ'el-e âh dar Irân, âb-hâ-ye sathi va zir-zamini va masâ'el-e bahre-bardâri az anhâ. Vol. 1.. (Sources and problems of water in Iran, surface and underground waters, and problems of their exploitation)
The A. divides his book into two sections, surface water and underground waters. He considers various governmental measures taken during the past decades for the study of measurement of water. He proposes possibilities for change| he deals with dams
, spring water and artificial wells, qanât and carst water. (ABSTR. IR.).

(Assessing the feasibility of water transfer from the South to the North by the Eastern route through historical records of drought).
Records of the occurrence of drought for the last 500 years in the three respective regions of water transferring, water exporting and water receiving schemes are analysed. Drought disasters occur simultaneously in 12 years out of every 100 in all
the three regions and of these 3 are severe droughts. There are also records of successive dry years of two to six years on a stretch These phenomena cast doubts on the feasibility of the proposed water transfer and special consideration for them is needed

Isotope hydrology of Mt. Tsukuba

The purposes of this study are : 1) to investigate temporal and spatial distribution of environmental isotopes of natural waters at a mountainous catchment| 2) to make clear the factors causing isotopic variation of natural waters| 3) to understand
the outline of subsurface water flow process in a mountainous catchment.

Physico-chemical analyses of river Water (Dungsel Khola, Central Nepal) were made before and during the monsoon. Differences in physico-chemical characteristics in response to the flow of Water are recorded and interpreted. Altitudinal zonation
of the river is emphazised in terms of physico-chemical characteristics of the Water.

Clean water for all: equity-based urban water supply alternatives for Indonesia's cities

Proposals for soil conservation, utilization of water bodies and mining in Hunan province.
Describes the rise in the rate of soil erosion in ten years, and its consequent damage to soil fertility, navigation, and water retaining capacity of lakes and reservoirs. Identifies the causes as deforestation, unsuitable exploitation of steep
slopes for agriculture, mineral prospecting, and fuel gathering. The loss of fishery resources resulting from the dwindling of water bodies is particularly lamentable. (TNC).
