IS 01 - ZONG, ISHKOSHIM: Irrigation
Agricultural land belonging to the village of Rotm in Zong Jamoat is situated adjacent tothe Pyanj River. It is supplied with irrigation water, via canals, from mountain streams and drainage is via a collector channel immediately adjacent to the river, hydraulically separated by an embankment to permit gravity discharge further downstream. A 1.6km length of embankment has been washed away by flooding resulting in ineffective drainage of some 200 ha of land and rendering much of that land at considerable risk of flooding.
Owing to the poor drainage, some 50 ha of this 200 ha plot is currently not cultivated.
The lack of embankment also means that this valuable and scarce agricultural land is subject to erosion at an estimated rate of 1 ha per year.
In order to improve the drainage of the agricultural land in question, and to prevent further erosion the drainage network will be de-silted and the stretch of collector destroyed by the river will be reconstructed. The precise cross section and alignment of the embankment that will form the outer wall of the drainage collector will be determined during detailed design by way of hydrological and morphological studies. The proposed interventions comprise:
- Cleaning of collector and drainage network 1000 m
- Rehabilitation of 2 sluice gates
- Reconstruction of outer wall and protection embankment of main drainage collector for a length of 1.6 km
- Provision of 1 hydraulic excavator for on-going maintenance of the embankment structure
- Provision of capacity building, training and advice to the local water users‟ association (WUA)
- Protection of 50 ha of irrigated land from flooding and returning it to cultivation
- Halting erosion of agricultural land
- Increase in crop yield level
IS 03 - VRANG, ISHKOSHIM: Flood Protection
The village of Trich in Vrang Jamoat is constructed with the Vrang stream running throughit, between two sections of residential properties. The stream is prone to flooding during times of high snow melt and considerable debris and mud flow characterizes such events.
Owing to the shape and roughness of the stream bed mud tends to block causing overtopping of the walls on either side of the channel. Damage to dwellings and lands then results.
Rehabilitation of stream bed in Trich Village, including:
- clearing channel of debris
- dismantling of existing stone walls
- re-construction of same in reinforced concrete and re-facing with original stone
- partial strengthening of Vrang stream bed downstream of the main road to Langar
- population: 12 households and their property
- irrigated lands; 2 ha
- road Langar-Ishkoshim 120 m
- power line
Land acquisition resettlement issues
- Temporary removal / dismantlement of private property boundary walls followed by reconstruction and re-facing with original some to preserve original appearance.
- Temporary disruption during construction
