<em>Generally, reservoir can overcome problem of water availability in particular region. The reservoir collects excess water during rainy season to be used at the time of water shortage during dry season. In Pidie, the largest water sources are from Krueng Baro Geunik and Krueng Tiro. The reservoir is located at Krueng Rukoh with Krueng Tiro as the source of water supply. The reservoir provides water for irrigating and supplying domestic water in Baro (11.950 ha) and Tiro (6.330 ha) areas. There are 13 districts (216718 inhabitants) use the water from this reservoir. Given the population growing at rate of 0.52% then the water demand in the region increases. The aim of study was to estimate the volume of water entering the reservoir using the tank model. Calibration curve between the tank model output and observation data showed good correlation (R<sup>2</sup> = 0.7). The calibrated model was then used to calculate the discharge at Krueng Baro Geunik. A water balance analysis showed that the highest deficit occurred in September and the highest surplus in November. Based on this analysis, the capacity of Krueng Rukoh reservoir is able to fulfill its function assuming the rate of population growth and the irrigation area are constant.</em>

Abstract : Tukad Penet is one of the biggest rivers in Bali which is used to support farming and fresh water demand. The increasing of water demand in various sectors such as for irrigation and drink water recently using water from Yeh Penet source shows the over use of its water has caused some conflicts between the use of the water user for irrigation and another use. Therefore, it was needed to review the use of Yeh Penet water to see how big the potential of its water that could be exploited to support the water source demand. The optimal analysis of water usage was carried out in six regional irrigation (DI) used Penet river water such as DI Peneng, DI Kacangan, DI Luwuscarang Sari, DI Penarungan, DI Kapal and DI Munggu. This analysis was based on cropping, planting and water management as well as a maximum water raw demand of the regional company of drinking water (PDAM) in Tabanan and Badung regency. Based on the simulation result, water availability in each irrigation regional (DI) depended on the cropping and planting. It was needed to provide the planting and rotation system for some irrigation regionals in river fluctuation discharge. The deficit of irrigation water balance occurred in DI Peneng, DI Luwuscarang sari, and DI Kacangan. The optimal use of irrigation water in the third irrigation regional was carried out by using planting stimulation and water management. The water balance analysis result at watershed in the part of downstream Penet watershed showed the availability of water surplus occurred in alternative plan I and II. The water balance analysis showed water availability in alternative plan I of a minimum 0.04 million m3 and maximum 1.43 million m3, whereas in alternative plan II the wasted water availability of a maximum 0.25 million m3 and a maximum 1.51 million m3. The potential development of Penet watershed in alternative plan I was 0.67 million m3 (0.52 m3/sec) and in alternative plan II was 0.76 million m3 (0.58 m3/sec) was not able to support the total water demand in Badung and Tabanan regency. Besides, the water source development of Penet watershed only occurred in downstream part of Yeh Penet river to avoid some conflicts of water utilization in Penet watershed.

Total Water Demand

Abstrak Sumberdaya air penting untuk pemenuhan kebutuhan semua makhluk hidup termasuk manusia. DAS Bodri menyediakan suplai air permukaan melalui sungai-sungai yang ada dalam DAS, yang dapat dimanfaatkan oleh penduduk sekitar. Seiring berjalannya waktu, DAS Bodri mengalami perubahan penggunaan lahan yang menyebabkan terjadinya peningkatan kebutuhan air dan terjadi ketidakseimbangan antara kebutuhan dan ketersediaan air permukaan. Tujuan dari penelitian ini, yaitu mengetahui keseimbangan antara kebutuhan air di masa yang akan datang dengan ketersediaan air permukaan di DAS Bodri tahun 2040. Perhitungan keseimbangan antara kebutuhan dan ketersediaan air permukaan dilakukan dengan membandingkan antara kebutuhan air total dan ketersediaan air permukaan. Parameter kebutuhan air total terdiri dari kebutuhan air domestik, fasilitas kesehatan, fasilitas pendidikan, fasilitas peribadatan, perkantoran, industri, pertokoan dan pasar, warung makan, peternakan, irigasi, dan tambak. Kebutuhan air di tahun mendatang diketahui melalui proyeksi secara eksponensial dan tetap dari data jumlah dalam perhitungan parameter. Kebutuhan air untuk aktivitas domestik dan nondomestik diestimasikan mencapai 2,44 miliar m3 pada tahun 2040. Hasil analisis neraca air menunjukkan bahwa status neraca air DAS Bodri tahun 2010-2019 mengalami defisiensi. Hal tersebut menunjukkan bahwa potensi sumberdaya air permukaan masih belum mencukupi untuk pemenuhan kebutuhan air di DAS Bodri hingga tahun 2040. Abstract Water resources play an important role in meeting the needs of all living things, including humans. The Bodri watershed provides surface water supply through rivers on the watershed, which the local residents can use and utilize. Over time, the Bodri watershed underwent landuse change, which led to an increase in water demand, resulting in an imbalance between water demand and surface water availability. Calculation of the balance between demand and surface water availability is done by comparing the total water demand and the surface water availability. This study aims to determine the balance between future water demand and surface water availability in the Bodri watershed in 2040. The parameters used to determine total water demand consist of water needs of the following sectors; domestic, health facilities, educational facilities, religious facilities, offices, industry, shops and markets, food stalls, livestock, irrigation, and ponds. In the coming year, water demand is known through projections exponentially and permanently from the amount of data in the calculation of parameters. Water demand for domestic and non-domestic activities is estimated to reach 2.44 billion m3 in 2040. The water balance analysis results show that the status of the Bodri watershed water balance in 2010-2019 is deficient. The potential for surface water resources is still insufficient to meet the water needs in the Bodri watershed until 2040.

The Impact

Currently, water demand is increasing, both domestic, industrial and agricultural water needs. However, the increase in water demand is not due to an increase in the water availability due to changes in land use and other factors that pose a threat to increased exploitation of water resources. So it is necessary to analyze and evaluate the water needs to anticipate the impact of drought in the Asem-Tekung-Jatirowo sub watersheds. The calculation of water supply and water demand can be carried out using the water balance method, assisted by the WEAP (Evaporation and Water Planning) program, through data integration of streamflow analysis and water user in the river reach. The results showed that the sub-watershed area showed a deficit of water in 2013, with the Jatiroto region having the highest air deficit of 1.58 million m3 or 44.2%. Based on this analysis, urgently needed a recommendation of drought anticipation strategies these are planting patterns to adjust condition of water supply, storage of water reserves, conservation of critical land, and repair of channels that are at risk of water seepage.

Depok sub-district in Yogyakarta is one of the most populous areas, which also develops rapidly. The Tambakbayan watershed, which includes Depok sub-district, has been seen as one crucial watershed in Yogyakarta. This study conducted a Thornthwaite-Mather water balance analysis in the watershed in order to understand its hydrology capability. The result of the study on three stream areas of the watershed (upstream, midstream and downstream) shows that the dry months begins in May- June and ends in September-October. August tends to be the driest month in the year with total deficit value reaches 179.2 mm. Still, the annual rainfall is higher than the annual evapotranspiration. The results also show that the lower area of the watershed has a lower capability to preserve water. However, the watershed still sufficient in providing the domestic water demand in the current state. Comprehensive water management plans suggested to be applied to protect the watershed from overstressing the water resources, especially in the downstream area.

Abstract Water is one of the sources of human life. Population growth continues to increase and results in higher utilization of water sources. This will certainly affect the availability of water in the city of Yogyakarta. Water balance is a comparison between the water availability potential and the water demand of a place in a certain period. Water balance analysis is useful for knowing the amount of excess water (surplus) or lack of water (deficit) so that water use can be managed as well as possible. The calculation was done by analyzing the 10-year rainfall data using the Thiessen Polygon method to obtain the mean rainfall value. The available debit was calculated using the F.J. Mock method. The dependable discharge was calculated with 80% reliability from the 10-year debit data. The debit data was sorted from the largest to the smallest value, so that a probability value of 80% was obtained from the interpolation of the data sequence. Water demand was calculated based on the irrigation planning standard (KP-01). The results of the study show that the average water availability in the sub-watershed of Code River Yogyakarta was 527.92lt/sec. Based on the results of the analysis, the highest water deficit occurred in the first October at 278.40 l/sec and the lowest deficit was in the second July at 73.01 l/sec. However, the availability of water in certain months was quite abundant. Therefore, it is necessary to do a special study so that water is not wasted and can be used to cover water shortages in dry months.
