Guidelines for predicting and minimising sedimentation in small
dams |
|
|
Many of the small dams constructed in semi-arid regions of Africa
rapidly fill with sediments, sometimes after only a few years.
When dams silt up the rural communities that rely on them for
cattle watering or small-scale irrigation are deprived of the
water and food security that dams provide, and their livelihoods
are seriously affected.
1. Guidelines for predicting and minimising sedimentation in small
dams. The guidelines present methods for estimating future siltation
rates and water yield reductions in dams subject to siltation.
Predicting soil erosion, sediment yields and dam sedimentation
rates can be a complex task, requiring specialist expertise, and
is generally poorly covered in small dam design manuals. The guidelines
enable dams where siltation rates will be unacceptably large to
be identified and the impact of remedial measure such as catchment
conservation to be quantified. The core procedure is based on
a rapid catchment characterisation exercise that enables catchment
sediment yields to be estimated. Tables are provided to aid the
calculation of future capacity and water yield reductions
2. Excel software supporting the guidelines. The software enable
calculations of future capacity and water yield reduction to be
carried out rapidly. [right click on the link {Software - 2},

3. Technical note describing the impacts of sedimentation in small
dams on the incomes of poor rural communities.
4. Technical note describing the hydrology and water yield computation
methods used in the guidelines.
5. Technical note describing the development of catchment characterisation
and sediment yield prediction procedure used in the guidelines.
6. Technical note describing methods used to estimate the potential
for catchment conservation, check dams and sediment bypassing
to reduce dam siltation rates used in the guidelines.

found in irrigated plains in arid and semi-arid countries. This
manual provides sufficient technical information to enable implementation

Increasing
the availability of water to communities does much more than satisfy
basic human needs. It makes it possible to embark on many activities
with economic value, such as small-scale irrigation, fruit orchards,
growing livestock feed, dairy units, fish farming and brick-making,
all of which are vital in alleviating poverty. This book demonstrates
the potential of groundwater resource to support production, both
through more effective use of existing water points and through
siting and design for new wells and boreholes. The findings are
presented in a practical manner to encourage planners and practitioners
to integrate the approach into existing rural water supply programmes
in drought-prone areas.

Sediment
Hydraulic Analysis for Rehabilitation of Canals (SHARC) allows
design engineers to identify sediment problems in irrigation
canals and evaluate different solutions. The program offers
6 modules:
- Problem
diagnosis and identification of technically feasible improvements.
- Preliminary
economic screening of options for improvement.
- Design
tools, including prediction of performance.
- Hydraulic
simulation and sediment routing to predict changes in whole-scheme
performance.
- Checklists
to assist Environmental Impact Assessment.
- Economic
analysis to derive an optimum economic solution
User
training is recommended.

ENCHECK
is designed to assist with the identification of environmental
effects of irrigation, drainage and flood control works. It is
an organiser of the information required for an environmental
study of such works and it follows the guidelines published in
"The ICID Environmental Check-list" (See: Irrigation and
Environment).

Run the OptALL
pre-processor |
OPTALL
is a package that can optimise the allocation of water resources
within complex irrigation distribution networks. The optimisation
routines are based on quadratic programming and have as their
objective minimising crop yield reductions resulting from water
stress, under the constraints of canal capacities and maintaining
equity in supply. The package and supporting documentation are
available from the School of Civil & Environmental Engineering
at the University of Edinburgh. The OptALL pre-processor can be
used to set up network files and gives an indication of the potential
of the package.

This
set of 24 slides shows examples of the different techniques available
for the monitoring of sediment in irrigation or water resources
projects. It also covers the kind of conditions likely to be associated
with various catchment sizes. The slide pack includes notes on
each slide and an overview of the subject. It is intended for
use by students and teachers.

Soil
erosion has a major, detrimental impact on agricultural productivity
and on water resource infrastructure such as dams and river diversion
structures. The slides in this pack provide examples of the causes,
effects and prevention of soil erosion. The pack is intended to
enable a teacher or lecturer to base teaching material on practical
situations. The slide pack includes notes on each slide and an
overview of the subject.

A
25 minute video describing how improved water measurement and
the feedback of information between managers, field staff and
farmers can improve the equity of supply and water use efficiency.
The video is intended as a training resource.

| Sediment
discharge measurement |
Output
summary
Order details |
The
14 minute video starts by describing the problems caused by excessive
sediment in rivers and canals. The ways in which sediments of
different sizes travel and the theory of sediment transport are
illustrated to show the differences between wash load, suspended
load and bed load. The theory is then developed into a field technique
to quantify the sediment discharge at a particular site. The pump
sampling method of measurement, developed by HR Wallingford, is
then described.

erosion measurement - a drainage basin approach |
Output
summary
Order details |
The first
part of this 25 minute video describes the conditions that promote
erosion, how erosion depends on both the quantity and intensity
of rainfall and the means of reducing the effects of rainfall
through land husbandry. The second half of the film describes
techniques for measuring sediment, the amount of water running
off the catchment and rainfall. The video is intended as a training
resource.
