  28. 28. Catchment Area Boundary Flood water in gullyTerrain Contour Storm water run-off SLOW LANES FAST LANES Before there was development in Unur, Today, there is less vegetation to absorb water, vegetation on the ground absorbed storm so more storm water reaches the gully. Since water before it reached the gully. 50% of the catchment area is developed with khashaas, run-off has increased by 5% to 10%.
  29. 29. A Section A – Steep slope B Extended Plot Section B – Flat area N 0 25 50 m. 0 5 10 m.WHY SOME AREAS FLOODWhere the gully is narrow and the slopes steep, the gully has enough space to carryflood water, but where the gully is wide and flat, the flood water spreads out. These flatareas are usually where khashaas owners have extended their plots.
  30. 30. EXISTING CONDITIONVehicles and people share an unpaved road located in a gully.
  31. 31. DO # 1 –Do allow water to absorb into the ground at the khashaaslevel by creating a trench filled with boulders and pebbles.
  32. 32. MIMIC ROLE OF VEGETATION ON KHASHAAS PLOTBy digging a trench and filling it with boulders, pebbles, or other coursematerials, khashaas owners can capture as much storm water on the plot aswould be retained by vegetation if the ground were in a natural condition.
  33. 33. DOS # 2 & 3 –Do make storm drains along roads with repaving.Do make culverts at places where road crosses storm waterdrainage and at khashaas entrances.
  34. 34. GABION WALL Stone and tires can be used MANY RESOURCES for gabion walls, but khashaas owners may be unwilling to give up land and the working season is very short.

Unur area to distribute information. RESETTLEMENT There already is a municipal policy for resettling residents away from vulnerable FEW RESOURCES areas, but the available land is far from the city center and lacks basic infrastructure, so the current policy doesn’t work for residents.HOW TO READ THIS MAP. . .This map interprets and summarizes participants’ discussion of resources and barriersfor implementing the toolkit. Residents thought, for example, that they already possessresources for the tools in the upper right quadrant, so these are the highest priorities.This map can help evaluate solutions, but is not the only decision-making tool.
