Three Rivers

Merauke Regency has three major rivers i.e Bian River, Kumbe River and Maro River (BIKUMA), the three rivers have large horizontal tidal potential. To know the potential of tides in the development of lowland irrigation in Merauke Regency needs to be studied. This study is supported by hydrometry and hydraulic surveys which has been conducted during the dry season during at spring tide and neap tide simultaneously for all three rivers. The survey included measuring river geometry activities with a range of 5 Km, river hydrometry measurements (observation of water fluctuations with proportional distances for model calibration and upstream river velocity for discharge). Limitations of river upstream measurements are limited by the distance where the Bian River along 125 Km, the River Kumbe along 171 km, and the Maro River along 66 km from the estuary. Then, performed a Sobek 1D hydrodynamic modeling that describes the movement of water from upstream into downstream. From the results of modeling is known that the water entering from the sea to the Bikuma River is greater than the water out to sea. The potential for tides is 1.7 Billion m3. Furthermore, the simulation of Sobek 1D2D to obtain the extent of natural condition, the area that can be inundated is 123.609 ha. Utilization of tidal potential can be channeled to the development zone through an integrated lowland irrigation water management system so that water utilization can be optimal.

<span><em>Damage to irrigation areas in Indonesia covering an area of 0.37 million hectares for severe damage and </em><span><em>an area of 1.25 million hectares for moderate and mild damage, has an impact on Indonesia's ability in </em><span><em>rice production; rice imports were almost half a century, and only the adequacy of rice was 2 X, i.e. 1984 </em><span><em>and 2009. This was due to low irrigation services which resulted in less optimal carrying capacity of food </em><span><em>security. The deterioration in the function of irrigation services can be grouped into 5 causes of low </em><span><em>irrigation pillars, namely: vulnerability of water sources, lack of irrigation infrastructure, low irrigation</em><br /><span><em>water management, weak management institutions, and low human resources. The cause will be eliminated </em><span><em>by the irrigation modernization program by working on these five pillars. One of the pillars in the </em><span><em>modernization of irrigation that needs to be improved is the irrigation management system.

Air, baik air tanah maupun air permukaan merupakan sumber kehidupan yang tidak dapat tergantikan oleh apa pun dan tanpa air, manusia, hewan dan tanaman tidak akan dapat hidup terutama sebagai air minum. Tetapi dalam pemanfaatannya, masih banyak yang tidak sesuai dengan peruntukannya ataupun mempergunakan sampai diluar batas, sehingga disatu sisi banyak yang terbuang dengan sia-sia tetapi dilain sisi banyak yang membutuhkan. Penggunaan air selama dasa warsa terakhir ini meningkat disebabkan oleh beberapa faktor, antara lain oleh kegiatan manusia yang semakin bervariasi, pertambahan jumlah penduduk yang meningkat, maka jumlah air untuk kebutuhan manusia juga meningkat dan hal ini berpengaruh terhadap kualitas air. Selain itu juga berpengaruh terhadap keterbatasan air dan kondisi alam. Untuk itu diperlukan suatu system pengelolaan air yang sangat baik dengan memperhatikan akan kondisi alam dan ketersediaan akan air sehingga tercapai suatu pengelolaan yang sesuai dengan tata kelola air. Kata kunci : air, pengelolaan air, lingkungan AbstractWater, both ground water and surface water is the source of life that can not be replaced by anything and without water, people, animals and plants will not be able to live.But in its utilization, there are still many who are not as intended or use to beyond the limit, so that on one hand many are wasted in vain, but on the other side of the many in need. Use of water during the last decade has increased due to several factors, among others,by human activities increasingly varied, the number of population increases, the amount of water for human needs has also increased and this contributes to water quality. It also affects the limitations of water and natural conditions. It required a water management system is very good with attention to natural condition sand the availability of water in order to reach an appropriate management of the water governance and the availability of clean wateris needed.  Keywords: water, water management, environment

Allocation Patterns

In this study, an integrated agricultural water management system based on interval mixed two-stage stochastic programming (ITSP) has been applied to the long-term planning of water management activities in Yongxin County, Jiangxi Province, China. A conjunctive use of water system is structured for characterizing the developed model. The model can effectively reflect dynamic, interactive, and uncertain characteristics of the water management system in the area. Solutions of the model provide optimal water allocation patterns for decision makers. The results are helpful to address the conflicts existing between the water resources and socio-economic development.

Due to extreme water scarcity Jordan is integrating reclaimed water resources in the national water management system. This paper describes the recent framework conditions for reclaimed water use in agriculture in Jordan, with a focus on the central and southern Jordan Valley. The possible impacts of lower quality irrigation water on soil, groundwater, crops and human health are considered while appropriate guidelines and monitoring proposals are being developed. Testing of the guidelines and implementation of the monitoring systems have started with the final purpose of integrating them into the Jordanian standard and legal system and thus ensuring safe food for consumers and protection of the environment.
