1 Water Harvesting from Roads in Ethiopia: Techniques and Approaches 1 By: Kifle Woldearegay 1, Frank van Steenbergen 2, Kebede Manjur 1, Marta Agujetas Perez 2, Taye Alemayehu 2 ( 1 Mekelle University, Ethiopia; 2 MetaMeta, The Netherlands) A Paper Presented at the International Conference on Geology, Mining, Mineral and Groundwater Resources of the Sub-Saharan Africa: Opportunities and Challenges Ahead ; July 11-13, 2017; Livingstone, Zambia
2 2 Outline 1. Introduction 2. Road and Water: Interactions and Effects 3. Approaches and Techniques of Road Water Harvesting (RWH) 4. Effects of RWH: Hydrological Monitoring 5. Design considerations for RWH 6. Concluding remarks
3 1. Introduction Road development 3 changes the hydrology (surface and groundwater) leading to: Concentrated surface runoff, or Altering groundwater movement. Concentrated water flow is a resource, if harvested/managed. How could roads be used to harvest/manage water?
4 Why water harvesting from roads? Road building is one of the 4 largest public investments. Unmanaged water from roads often lead to negative effects including to the road itself. Water scarcity is a major issue in many parts of Ethiopia, and SSA. Managing water from roads has economic, social and environmental benefit; an opportunities to be tapped.
5 2. Road and Water: Interactions and Effects 5 Ethiopia (a) Increase in erosion of local streams and road side drainages Ethiopia Nigeria
6 6 (b) Sedimentation: reservoirs, farm lands, roads, etc
7 (c) Water logging/flooding 7 (Highland) (Lowland)
8 (d) Opening springs 8 Spring: road cuts in mountainous area. Spring: in flat areas at soil-rock interface.
9 9 Typical Example of a bridge under annual maintenance due to siltation problem Waja town Flood protection Downstream Upstream Panoramic View of Waja bridge, Waja area, Tigray, Ethiopia
10 (e) Water-induced 10 hazards Landslides Earth fissures
11 3. Approaches and Techniques: Water Harvesting from roads in Ethiopia Approaches Agricultural Offices: overall lead. Woreda Offices: coordinating the implementation. Communities: Implementing the interventions. Road contractors and consultants: support the overall activity. Research consortium: capacity building, evidence generation, and sharing.
12 3.2 Techniques Used 12 (a) Construction of Deep trenches at downstream side of roads to recharge the groundwater and improve moisture conditions of soils. Culvert Deep trenches
13 (b) Road side ponds/ pits to recharge groundwater and enhance in-situ moisture in soils
14 14 (c) Road side runoff or water from culverts stored in ponds for surface water storage and groundwater recharge.
15 Pond 15 (d) Water from culverts channeled into farmlands (used for groundwater recharge and improving soil moisture. Diversion Culvert
16 16 (e) Road side runoff is channeled into farmlands (used to improve soil moisture and reduce runoff to downstream areas).
17 (f) Runoff from a town (Freweign) is managed through a number of options: 17 Construction of deep trenches to reduce runoff and enhance groundwater recharge. Diverting water from culverts into a borrow pit for surface water storage and groundwater recharge. Borrow pit Culverts Deep trenches Communities which used to have been affected by flooding are saved from flooding.
18 Road 18 Check-dam (g) Water from culvert is channeled into check-dams (for surface water storage and groundwater recharge. Hand-dug well Bridge Gabion check-dam
19 (h) Water from a bridge is spread into series of 19 deep trenches and percolation ponds to recharge groundwater. Hand-dug well which used to be dry became productive after the intervention. Bridge Hand-dug well Deep trenches Percolation pond (i) Road side drainage connected to percolation pond for groundwater recharge. Road side drainage
20 20 (j) Hand-dug wells at upstream of Irish Bridge in Megab area, Tigray, Ethiopia. Irish Bridge Hand-dug well Irish Bridge with handdug well at upstream. Hand-dug well upstream of the Irish Bridge
21 Culvert 21 (k) A pond developed for harvesting water from culverts and Bridges in Northern Ethiopia: To enhance water availability during the 2015/2016 droughts. Pond Pond Bridge 21
22 22 (l) Roads as dam embankments; used for: Surface water storage, Water Road Sediment/Sand storage. Groundwater recharge. Water Road
23 23 4. Effects of Road Water Harvesting: Hydrological Monitoring Positive effects: Enhancing recharge to shallow groundwater, Enhancing soil moisture (in-situ), Cessation of gully expansion, Reduction in flooding, Enhancing productivity as supplementary irrigation, Sources of water in drought periods.
24 Groundwater level below surface (m) 4.1 Effects on groundwater level 24 Water from a culvert and road side drainage channeled into a pond: Enhanced the shallow groundwat er Groundwater level flactuation in Freweign area, Tigray, Ethiopia Month Note: Borrow pit was used as water storage in the month of July
25 Groundwater level below surface (m) 4.2 Effects of checkdams Culvert 25 Check-dam Month Hand-dug well
26 In-situ moisture (%) 4.3 Effects on soil moisture In-situ moisture distribution in soils (Megab area, Tigray, Ethiopia) W1 W2 W3 W4 W1 W2 W3 W4 W1 W2 W3 W4 Sept Oct Nov Month
27 4.4 Supplementary irrigation 27 Diverting water from culverts and roadsides are important sources of water for supplementary irrigation. Productivity has increased by 50% in 2014/2015 harvest season.
28 4.5 Sources of water in dry periods Sept Ponds are important sources of water in dry periods: as witnessed in 2015/2016 drought periods. April 2016
29 5. Design considerations for RWH 5.1 Scenarios and approaches 29 Three options could be considered: Use existing roads to harvest/manage water. Design modifications to existing roads. Adapt and implement new design approach: integrate road water harvesting options: Guideline/standard.
30 In all the three options, a landscape continuum approach is preferred: 30 Road Road development: based on landscape continuum water management model. Different techniques along the landscape: upstream, integrated with roads, and downstream of roads.
31 5.1.1 Techniques at Upstream/Upslope 31 Techniques that: Enhance infiltration, Reduce erosion, flooding and siltation, Enhance soil moisture and groundwater recharge. Example: Surface runoff has reduced by 80% as a result of the upstream intervention.
32 5.1.2 Techniques integrated with the roads Roads: as water storages and diversions. 32 Water Road as dam embankment River crossings: water buffering. River crossing Pond Water and sand at upstream of crossings Roadside runoff diverted into a pond
33 5.1.3 Techniques at Downslope/ Downstream Culvert Promote 33 technologies that: Storage surface water, Enhance groundwater recharge, Control flooding, Reduce negative effects: erosion, siltation, etc Enhance sustainable/ productive use of water. Check-dam Hand-dug well Culvert
34 6. Concluding remark a. There is a great potential to turn 34 the negative effects (of water from roads) to positive through introduction of appropriate technologies. b. Road development is part of land use planning: need for collaboration among various sectors. c. Towards multi-functional and climate resilient roads: adapt landscape continuum based water management. d. Develop guidelines and standard procedures for road water management. Road Culvert Water channeled into farm lands Pond
