Abstract. The area of agriculture in the Moyo Hulu sub-district of Sumbawa Regency is 6000 hectares with irrigation water sources from Batu Bulan Dam, which is the largest dam in Sumbawa Regency with an area of 932 hectares. Considering that Sumbawa Regency is one of the regions with a high level of drought, information on irrigation water requirements for land preparation needs to be known because it can optimize the allocation of the use of dam water discharge. And one of the important stages needed in the planning and management of irrigation systems. Based on this, the aim of this study is to forecast water requirements for land preparation in the irrigation area of Batu Bulan Dam by using cyclical methods because the data patterns are cyclical or seasonal. The factors that influence water requirements for preparing agricultural land are topography, hydrology, climatology and soil texture. From these factors, the data is then analysed so that the volume of water preparation needs to be obtained every month so that the results of the analysis can be predicted for the next period.

Abstract Accurate quantification of irrigation water requirement at different physiological growth stages of okra (Abelmoschus esculentus L.) life cycle is important to prevent over or under irrigation. Field experiments were therefore initiated to model okra irrigation water requirements at the four physiological growth stages of okra life cycle using CROPWAT model. Derived savannah 1 (DS1), derived savannah 2 (DS2) and humid forest (HF) occupying 493.36 ha, 69.83 ha and 305.25 ha respectively were used. Some selected soil physical properties coupled with weather parameters were used to develop irrigation water requirements for okra crop. In DS1, the estimated crop co-efficient (Kc) values were 0.30, 0.52, 0.84 and 0.70 for the germination, crop growth, flowering and fruiting stages, respectively. Corresponding Kc values in DS2 were 0.30, 0.54, 0.90 and 0.84 and in the HF were 0.30, 0.56, 0.87 and 0.86 respectively. Daily crop evapo-transpiration values ranged from 1.16 to 3.36, 1.17 to 3.64, and 1.2 to 3.38 mm day-1 for DS1, DS2 and HF respectively with significant (p = 0.05) peak at the flowering stage for the three locations. Sustainable okra cultivation would require maximum daily irrigation water at flowering stage (reproductive phase) to meet the crop physiological needs and evapo-transpiration demand of the atmosphere.

According to Kunming 1980-2010 monthly weather data and CROPWAT software and the corresponding crop data, crop water requirements and irrigation water use are calculated. By frequency analysis, irrigation water requirement was get for different guaranteed rate. The results show that: corn, potatoes, tobacco, and soybeans average crop water requirements were 390.7mm, 447.9mm, 361.8mm and 328.4mm, crop water dispersion coefficient is small, period effective rainfall during crop growth in most of the year can meet the crop water requirements, so irrigation water demand is small. While the multi-year average crop water requirements were 400.8mm, 353.5mm, 394.3mm for small spring crops of wheat, beans, rape. Because the effective rainfall for these crops during growth period is relative less, crop irrigation water requirements for small spring crop is much. Vegetables and flowers are plant around the year, so the crop water and irrigation water requirements are the largest.

The Cubo Trienggadeng Irrigation scheme has a potential area of 1,545 Ha while the functional area is 1,090 Ha. Based on the Irrigation Network scheme, Cubo Trienggadeng Irrigation Area consists of 3 (three) zones: Zone I, Zone II and Zone III. In Zone III of the Cubo Trienggadeng Irrigation Area which is the latest area receiving water from the Cubo Trienggadeng Weir often occurs in water shortages especially during the Gadu planting season (second planting season). Embung Paya Sepat is the reservoar found in Zone III D.I. Cubo Trienggadeng that is not being fully optimized in use. This study aims to optimize the utilization of Paya Sepat Reservoar so that it can meet irrigation water demand in Zone III D.I Cubo Trienggadeng by using the Water Balance method. This reservoar does not have a channel that supplies inflow discharge, so rainwater harvesting becomes a parameter in analyzing the supply of water to the reservoar. The optimization technique used uses a non-linear program using the Solver facility in Microsoft Excel software. Based on the results of the calculation of irrigation water requirements for an area of 204.50 Ha in the Gadu planting season, the maximum volume of irrigation water demand is 40,461,55 m3 at first periode in June, from the results of the optimization using the Maximize Release method, the results show that the water reservoar in Paya Sepat Reservoar can meet the water requirements in the Gadu planting season with an average reliability of 100%.. Therefore it is necessary to regulate the release of irrigation water that is well regulated and coordinated between the reservoar management and water users/farmers.

Abstract. Irrigation agriculture plays an increasingly important role in food supply. Many evapotranspiration models are used today to estimate the water demand for irrigation. They consider different stages of crop growth by empirical crop coefficients to adapt evapotranspiration throughout the vegetation period. We investigate the importance of the model structural versus model parametric uncertainty for irrigation simulations by considering six evapotranspiration models and five crop coefficient sets to estimate irrigation water requirements for growing wheat in the Murray–Darling Basin, Australia. The study is carried out using the spatial decision support system SPARE:WATER. We find that structural model uncertainty among reference ET is far more important than model parametric uncertainty introduced by crop coefficients. These crop coefficients are used to estimate irrigation water requirement following the single crop coefficient approach. Using the reliability ensemble averaging (REA) technique, we are able to reduce the overall predictive model uncertainty by more than 10%. The exceedance probability curve of irrigation water requirements shows that a certain threshold, e.g. an irrigation water limit due to water right of 400 mm, would be less frequently exceeded in case of the REA ensemble average (45%) in comparison to the equally weighted ensemble average (66%). We conclude that multi-model ensemble predictions and sophisticated model averaging techniques are helpful in predicting irrigation demand and provide relevant information for decision making.

Cikarang Bekasi Laut (CBL) is a fixed-dam river-flow that flows through the building for upstream srengseng channel. Srengseng Hilir Secondary-Channel has 32 buildings for watering the rice fields in the Sukatani sub-district. The problem happened in the distribution of water when there is a loss of irrigation water due to infiltration of water into the soil where the soil is saturated. This causes a shortage of debit for field irrigation due to water loss in the secondary channel. The method used in Water Supply Evaluation of Irrigation Cikarang Bekasi Laut (CBL) for the Secondary Channel Srengseng Hilir D.I. Jatiluhur are the maximum discharge data, minimum discharge, and average discharge of the Fixed Cikarang Bekasi Laut (CBL) Dam in 5 year-period and calculating water requirements and water availability in D.I. Jatiluhur. Result showed that the P1 channel has an irrigation area of 105 ha and a channel length of 1906 m with an actual discharge of 2714 liters/sec and has irrigation efficiency of 5.71%.
