Abstract

Blorong small dam situated on the Blorong River, Kendal Regency. Blorong small dam is planned to meet the requirement of water in Kedung Pengilon irrigation area experiencing water shortages during the dry season, the months of September and October. Area has experienced drought during the dry season is expected around 1200 Ha. Discharge mainstay Blorong River calculated based FJ. Mock method with the possibility of not being met by 20%. Small dam reservoir volume is 1,589,705.56 m3 which is at an elevation of +39,00 to +53,00. Results of water balance calculations indicate that in September and October there is a shortage of water, each for 1.253.648 m3 and 122.758 m3. Flood discharge plan obtained from HSS Gama I method is equal to 503.7558 m3/s return period of 25 years (Q25 = 503.7558 m3/s). The planned small dam 19 m high, with a base elevation ponds +39.00, +58.00 dam crest elevation, surveillance 2.00 m high, 7.00 m wide dam crest, upstream slope of 1:2,5, 1:1,75 downstream slope. In planning this Blorong small dam used ogee type spillway width 30.00 m with a height of 14 m and a spillway crest elevation of +53.00, using an eject USBR Type IV with a length of 15.70 m. This project implementation is scheduled for 35 weeks with a budget plan  of Rp 24.242.419.000,00.

Abstract

In addition to the construction of an alternative form of water reservoirs, to tackle the problem at the Weirs Karangtalun can also be by way of construction of the barrage. The reason for the need for the construction of the dam movement emerged based on the survey results, which show that Karangtalun weir downstream conditions are now damaged due deggredasi riverbed downstream. Weir crest had already suffered some damage due to collision damage to the stone. It is feared that one day the dam will collapse.Barrage to capture the motion of the water to drain Progo river can be more time in the count because of the barrage that comes w ith taking the doors and door rinse. raw water needs in the catchemet area Progo 2 of irrigation kalibawang and mataram, flood discharge plan is designed with 100-year return period of 1157 m3/sec.Barrage height of 10 m. Weir is equipped with radial main door, stilling basin using the threshold type width of 35 m. Construction of barrage to cost about 222 billion and a plan of implementation 40 weeks.

Abstract

Increasement of water demand that caused from the population increasement and land use change over at Progo Basin, inversely with water supply to that area. So that, the solution to conquer the problem is to build a water reservoir. One of the alternative is Salak Dam which located at Kalibawang District, Kulon Progo Regency, Yogyakarta. Salak Dam is a vertical core earthfill dam, which built on Salak River with 9.4 km2 of catchment area. This dam aims to fulfill public water supply and watering three fields area and designed with 100 years of return period with inflow discharge valued 46.9 m3/second. Salak Dam designed 48.5 meters of height, with 18.5 million cubic meters of capacity. This dam equipped with 2.2 meters of diameter outlet pipe, Ogee type of spillway with 20 meters of width, and USBR III of stilling basin. Construction of Salak Dam costs around 450 billion Rupiahs and scheduled for 39 weeks.

Abstract

Drainage system with retention pond and pumping station is the most effective and efficient system to manage flood in drainage area. Semarang River catchment area has became one of important area in Semarang, because it ends near Tanjung Mas Port, that is basically one of central business district in Semarang, so that the flood which inundate that area become major problem for local government. Retention pond and pumping station drainage system are designed using 10 year return period flood discharge. From the result of 10 year recurrence interval rainfall data processing by using Nakyasu method, thus can be obtained Q design = 63,983 m3/sec, that  will be used to design drainage channel. By comparing existing drainage channel and designed drainage channel, it’s obtained that drainage channel in M.H. Thamrin Street and Gajah Mada Street need to be replaced, because they can’t intercept and retain flood discharge. By using flood routing method with 10 year recurrence interval Q, it can be obtained the area of retention pond  is 68.000m2 and 88.400m3 with  8  pumps in total with 5 m3/sec capacity for each pump.

Abstract

Juana river’s located in two administrative regions Kudus and Pati had superficial. This is because the slope of the river is quite gentle and the level of environmental degradation in the watershed (DAS) Juana river’s have increased. Based on these conditions, it is necessary to plan the construction of sediment control (check dams) to reduce sedimentation along the river and optimize the function of the Juana river’s. Planning is performed on Dawe river’s ,the branch of Juana river’s. From the calculation results obtained 7 m high main dam, main dam foundation depth of 2,8 m, width of crest main dam 32 m, the water level above the crest 1,60 m, high freeboard 0,6 m, thick of main dam crest wing 2 mand capacity of sediments for 20.851,063  m³. The total cost needed to build the check dam Dawe river’s is Rp. 6.511.846.000,00 already includes VAT and 23 weeks old craftsmanship.
