The manual assists both national and donor agency planners to determine the need for and carry out a program to improve the tertiary irrigation conveyance systems. Topics covered include evaluating and diagnosing problems in the present channel systems, proposing and testing solutions to the diagnosed problems, combining the solution techniques into improvement strategies, evaluating the improvement strategies and developing the institutions necessary to carry out the improvement programs. The manual deals both with processes, which will be of primary interest to the planners; and techniques, which would be useful to the engineers, economists and sociologists.

(Location: IWMI-HQ Call no: 627.122 G662 FIS Record No: H0540)
This report contains details of a hydrographic survey carried out in July 1982 of Wlingi reservoir which is situated on the Brantas river, East Java, Indonesia. The survey revealed that the reservoir appears to be silting up at a rate which is five times greater than was expected at the design stage. Most of the sediment appears to be entering the reservoir from tributaries originating in valleys affected by the lava flows from the eruptions of the volcano Gunung Kelud. Debris control structures in these tributaries are thought to be almost full and consequently no longer trap sediment effectively. This is presented as the major reason for the large increase in sedimentation rates in Wlingi reservoir.
6 Kadiro, D.; Santoso, T. 1982. Warujayeng-Kertosono canal survey. Wallingford, UK: Hydraulics Research Station. 41p. (Hydraulics Research Station report no.OD/42)
(Location: IWMI-HQ Call no: 631.7.6.2 G673 KAD Record No: H0380)
The Warujayeng-Kertosono canal has experienced siltation problems since 1951. The canal is to be rehabilitated and quantitative estimates of the sediment problem are needed. This report analyses the data gathered from surveys carried out in 1975 and 1981. The results highlight the need for sediment exclusion or extraction presently being carried out by a dredger.

(Location: IWMI-HQ Call no: 627.122 G662 BRA Record No: H0268)
A programme of research was undertaken to study the siltation of Karangkates reservoir, East Java, Republic of Indonesia. The objectives of the research are: (1) To quantify the amount of sediment deposited within the reservoir since impoundment. (2) To determine the distribution of that sediment within the reservoir basin. (3) To identify areas of significant erosion within the catchment and to measure the sediment yield from these areas to the reservoir. To provide background knowledge, data collected from various sources is presented in this report. The data includes rainfall, river flow and sediment discharge. Suggestions on how to improve and continue the data collection network are included.
9 Warner, J. W.; Gates, T. K.; Fahim, W.; Ibrahim, M.; Awad, M.; Ley, T. W. 1984. Hydraulic conductivity and vertical leakage in the clay-silt layer of the Nile alluvium in Egypt. Cairo, Egypt: Egypt Water Use and Management Project. ix, 88p. (EWUP technical report no.60)
(Location: IWMI-HQ Call no: 631.7.2 G232 WAR Record No: H0878)
Data were collected from three sites in Egypt's Nile Valley and Delta to determine saturated hydraulic conductivity in the clay-silt water table aquifer and vertical leakage to the underlying Nile River sands. Auger hole test results gave saturated horizontal hydraulic conductivities of 1103 mm/day for Abyuha in the Middle Nile Valley, 197 mm/day for Beni Magdul near Cairo, and 103 mm/day for Abu Raya in the northern Delta. Auger hole, permeameter, and consolidation tests resulted in saturated vertical hydraulic conductivities of 0.03 to 4.9 mm/day for Abyuha, 0.03 to 0.87 mm/day for Beni Magdul, and 0.03 to 0.45 mm/day for Abu Raya. Several methods were used to determine vertical leakage: Darcy's law, water table decline, water budget, pumping test, and analytical solution. Average vertical leakage rates were very low for each site: 0.59 mm/day in Abyuha, 0.64 mm/day in Beni Magdul and 0.47 mm/day in Abu Raya. These results indicate poor natural drainage characteristics in the clay-silt layer which contribute to the high water table conditions observed throughout Egypt.
