Daily Water

This study aimed to develop a water balance model capable of daily analysis of the water supply situation in a multi-composite area, evaluate the utility of the model, and conduct a water balance analysis. The multi-composite water balance model, which was developed to determine the daily water balance in an area, includes five modules: "Weather data build and area mean data," "Rainfall-runoff analysis," "Benefit area and demand estimation," "Reservoir water balance analysis," and "River basin water balance analysis." The study selected eight cities in northwestern Chungcheongnam-do in Korea as target areas and evaluated the utility of the water balance model. Further, the study used observation and model simulation data for its analysis, which found a high degree of accuracy as well as correlation. In addition, daily water balance analysis was conducted to estimate the potential supply, demand, supply, shortage, surplus supply, and shortage days in the river basin, while the ratio of shortage to demand was also determined to identify areas vulnerable to drought. In the future, it will be possible to establish drought countermeasures and facility operation plans by identifying areas with water supply vulnerability using the developed model.

The article presents the results of the field studies and observations that carried out on the territory of the hilly, low-mountain and foothill agro landscapes of the Kyzylsu-yuzhnaya (Kyzylsu-Southern) River Basin of Tajikistan. Taking into account the high-altitude location of households and the amount of precipitation in the river basin, the annual volumes of water accumulated with the use of low-cost systems of collection and storage of precipitation have been clarified. The amount of water accumulated in the precipitation collection and storage systems has been established, the volume of water used for communal and domestic needs,the watering of livestock and the amount of water that can be used to irrigate crops in the have been determined. Possible areas of irrigation of household plots depending on the different availability of precipitation have been determined. It has been established that in wet years (with precipitation of about 10%) the amount of water collected using drip irrigation will be sufficient for irrigation of 0.13 hectares, and in dry years (with 90% of precipitation) it will be possible to irrigate only 0.03 ha of the household plot. On the basis of the basin, the total area of irrigation in wet years can be 4497 ha, and in dry years only 1087 ha. Taking into account the forecasts of population growth by 2030 and an increase in the number of households, the total area of irrigation of farmlands in wet years may reach 5703 hectares,and in dry years – 1379 hectares. Growing crops on household plots under irrigation contributes to a significant increase in land productivity and increases the efficiency of water use of the Kyzylsu-yuzhnaya basin.

<p>Area studi terletak di bagian tenggara Dataran Tinggi Blackwood, Australia Barat mencakup 71 km<sup>2</sup>. Akifer Yarragadee di daerah studi utamanya tersusun oleh batu pasir yang mengandung lapisan-lapisan batu lempung dan liat. Akifer ini merupakan akifer tak-tertekan karena muncul dipermukaan sepanjang alur Sungai Blackwood pada daerah hilir di Nannup dan merupakan sumber airtanah yang keluar ke sungai. Sungai Blackwood mengalir melintasi Dataran Tinggi Blackwood. Selama musim kering, aliran permukaan ke dalam Sungai Blackwood dapat diabaikan, namun aliran dasar dari airtanah menjadi sumber utama bagi aliran sungai. Neraca air pada daerah studi dilakukan dengan menggunakan analisa jaring-aliran dan kesetimbangan air guna mengevaluasi masukan airtanah dari akifer Yarragadee ke dalam Sungai Blackwood. Mayoritas sel-sel jaring-aliran adalah sel-sel keluaran dan kebanyakan aliran airtanah masuk ke dalam Sungai Blackwood di daerah studi. Curah hujan rata-rata tahunan area studi sekitar 6.7 x 10<sup>7</sup> m<sup>3</sup> a<sup>-1</sup>. Sekitar 9 % dari total curah hujan rata-rata tahunan ini masuk ke dalam tanah sebagai sumber bagi air tanah dan 91 % hilang melalui proses evapotranspirasi. Volume total airtanah yang masuk ke dalam Sungai Blackwood antara stasiun Darradup dan Layman Flat yang dihitung menggunakan analisis jarring-aliran dan kesetimbangan air sekitar 8.1 GL a<sup>-1</sup>.  </p>
