Abstract

Management of the conjunctive use of surface and groundwater resources is essential, as the combination of these two water resources result in huge advantages for the quality of water, irrigation and economic benefit for the farmers and country. The advantages of proper conjunctive management not only secure the availability of water in the whole year but also can be utilised to provide safer potable water for humans. However, it is not an easy thing to manage both resources since they face several challenges and causes conflict because the nature of surface and groundwater resources is very far different. Furthermore, in order can be used as a safe drinking water then the water resources have to be managed free from contaminants and pollutants. In term of economy, better irrigation system could increase the quality and the quantity of crop’s harvest, make the soil more fertile and productive, and elevate horticulture and viticulture industries. All these things are very essential not only to increase better lives of farmers but also lead to many economic gains to the nation.

Abstract

Excess water capacity in river areas will cause flood hazards that mostly occur in downstream areas that are flood areas at high risk as a result of natural processes and the effects of human actions. In the case of floods, water runoff undermines the embankments and drowns agricultural / settlement areas upstream, and is aggravated by considerable sedimentation. Based on the existing problems, the analysis of the discharge and the water level (water profile) becomes very important to get a precise picture of locations prone to the overflow of the river Kr. This pase. Discharge and water profile analysis using HEC RAS software for various return periods. From the results of the research is expected to get a clear picture of the location that is vulnerable to overflow so that in handling the river will be on target. Based on the calculation using HEC RAS software, at point P 581 the water level condition at 2.3 years discharge the difference of the height of the embankment and the water level is 50 cm to 60 cm, while in the discharge condition 25 years the elevation of the face almost passes through the dike's height with a selisish of about 10 -15 cm. This condition is an unsafe category because for rivers whose debit is greater than 15 m3/s the minimum wavelength is 1.00 m. So that with good conditions at 2.3 years discharge and 25 years of discharge is very potential to occur overflow.Keywords: discharge, waterlevel, flood

Abstract

This study involves the assessment of the performance of technical irrigation system in Aceh, Indonesia, namely the Pante Lhong technical irrigation system. The Pante Lhong technical irrigation system performances were evaluated using measured internal and external indicators that covered different aspect of evaluation. The Rapid Appraisal Process (RAP) is a visual assessment tool was used to evaluate the internal indicators performance. The selected indicators were grouped in terms of actual water delivery service performance and infrastructure maintenance. The external indicators were crop yield and production cost. The data are collected from the farmers in the three regions which were upstream, middle stream and downstream. Data were collected through field observation and face to face interviews with the irrigation staff and the farmers. The results for the infrastructure maintenance indicators showed that the current canal network received 74.25 % of the expected infrastructure maintenance. The results also found that the continuous supply method is quite enough to excellent performance of flexibility, reliability and equity of water distribution. However, the control flow to farmers in the next level at third canal/tertiary level and measurement of volumes delivered sub components had performed at worse than expected. In the crop yield indicator, the average maximum productivity was 3.91 ton/ha and the income generated was Rp. 11.730 million rupiahs/ha. The total production cost of the Pante Lhong technical irrigation system was Rp. 4.126 million rupiahs/ha and hence in term of return of investment (ROI), it is still profitable and feasible to be developed for the farmers.
