IV. PROPOSED PROJECTS
(Projects designed and awaiting
implementation)
1.0 Abu Delieg Water Harvesting
Project
Location: 45 km south east of El Fashir,
North Darfur State.
A1.1 Problem Statement
N initial project was constructed
by the Rural Water Corporation
in 1972. The project consisted of the
following:
- An earth embankment of total
length = 4,040m
- Spill way water structure
(masonry work), length = 26.40 m
However, the earth embankment was
washed out at different sections along the
western, eastern and southern sides. The
total length of the washed out sections
is about 250m. The project is no longer
functioning because of this damage and
crops of sesame, groundnuts, vegetables
and watermelons that were grown there
have suffered.
T1.2 Project Goal
HE goal of the project is to
rehabilitate the current, damaged
structures.
T1.3 Project Description
HE project will involve the
following activities:
i. Remodelling and raising the existing
earth embankment to the level of
101.60m.
ii. Raising the existing old spillway
18
crest by 25.0cm and erecting 3 pipes
(8in each in diameter) at the spillway
wall to control the silt upstream of the
structure.
iii. Building 4 new structures to support
the original design and 3 of them to be
used to distribute the water harvested
through a system of canals while the 4th
is for draining part of the floodwater.
Canals: For proper water spreading to
be achieved, three canals are proposed:
- Canal A: Fed by New Structure No. 4
- Canal B: Fed by New Structure No. 3
- Canal C: Fed by New Structure No. 1
Field watercourses take water from
the canals, through pipes, to flood the
agricultural land.
Construction:
New Structure No. 1: The structure has
four gates, all 0.50m in diameter, for
silt control, flood control and water
regulation to Canal C.
- Spillway crest level = 100.00m
- Spillway crest length = 21.0m
New Structure No. 2: The structure has
one gate, 0.76m in diameter, for silt
control and flood control.
- Spillway crest level = 100.00m
- Spillway crest length = 7.0m
New Structure No. 3: The structure has
two gates, 0.35m in diameter each, for
silt control, flood control and water
regulation to Canal B.
- Spillway crest level = 100.40m
